# WordPress packaged by Bitnami
WordPress is the world's most popular blogging and content management platform. Powerful yet simple, everyone from students to global corporations use it to build beautiful, functional websites.
[Overview of WordPress](http://www.wordpress.org)
## TL;DR
```console
$ helm repo add my-repo https://charts.bitnami.com/bitnami
$ helm install my-release my-repo/wordpress
```
## Introduction
This chart bootstraps a [WordPress](https://github.com/bitnami/containers/tree/main/bitnami/wordpress) deployment on a [Kubernetes](https://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
It also packages the [Bitnami MariaDB chart](https://github.com/bitnami/charts/tree/main/bitnami/mariadb) which is required for bootstrapping a MariaDB deployment for the database requirements of the WordPress application, and the [Bitnami Memcached chart](https://github.com/bitnami/charts/tree/main/bitnami/memcached) that can be used to cache database queries.
Bitnami charts can be used with [Kubeapps](https://kubeapps.dev/) for deployment and management of Helm Charts in clusters.
## Prerequisites
- Kubernetes 1.19+
- Helm 3.2.0+
- PV provisioner support in the underlying infrastructure
- ReadWriteMany volumes for deployment scaling
## Installing the Chart
To install the chart with the release name `my-release`:
```console
helm install my-release my-repo/wordpress
```
The command deploys WordPress on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) section lists the parameters that can be configured during installation.
> **Tip**: List all releases using `helm list`
## Uninstalling the Chart
To uninstall/delete the `my-release` deployment:
```console
helm delete my-release
```
The command removes all the Kubernetes components associated with the chart and deletes the release.

| `externalDatabase.port` | External Database server port | `3306` |
| `externalDatabase.user` | External Database username | `bn_wordpress` |
| `externalDatabase.password` | External Database user password | `""` |
| `externalDatabase.database` | External Database database name | `bitnami_wordpress` |
| `externalDatabase.existingSecret` | The name of an existing secret with database credentials. Evaluated as a template | `""` |
| `memcached.enabled` | Deploy a Memcached server for caching database queries | `false` |
| `memcached.auth.enabled` | Enable Memcached authentication | `false` |
| `memcached.auth.username` | Memcached admin user | `""` |
| `memcached.auth.password` | Memcached admin password | `""` |
| `memcached.service.port` | Memcached service port | `11211` |
| `externalCache.host` | External cache server host | `localhost` |
| `externalCache.port` | External cache server port | `11211` |
The above parameters map to the env variables defined in [bitnami/wordpress](https://github.com/bitnami/containers/tree/main/bitnami/wordpress). For more information please refer to the [bitnami/wordpress](https://github.com/bitnami/containers/tree/main/bitnami/wordpress) image documentation.
Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
```console
helm install my-release \
--set wordpressUsername=admin \
--set wordpressPassword=password \
--set mariadb.auth.rootPassword=secretpassword \
my-repo/wordpress
```
The above command sets the WordPress administrator account username and password to `admin` and `password` respectively. Additionally, it sets the MariaDB `root` user password to `secretpassword`.
> NOTE: Once this chart is deployed, it is not possible to change the application's access credentials, such as usernames or passwords, using Helm. To change these application credentials after deployment, delete any persistent volumes (PVs) used by the chart and re-deploy it, or use the application's built-in administrative tools if available.
Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
```console
helm install my-release -f values.yaml my-repo/wordpress
```
> **Tip**: You can use the default [values.yaml](values.yaml)
## Configuration and installation details
### [Rolling VS Immutable tags](https://docs.bitnami.com/containers/how-to/understand-rolling-tags-containers/)
It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.
Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.
### Known limitations
When performing admin operations that require activating the maintenance mode (such as updating a plugin or theme), it's activated in only one replica (see: [bug report](https://core.trac.wordpress.org/ticket/50797)). This implies that WP could be attending requests on other replicas while performing admin operations, with unpredictable consequences.
To avoid that, you can manually activate/deactivate the maintenance mode on every replica using the WP CLI. For instance, if you installed WP with three replicas, you can run the commands below to activate the maintenance mode in all of them (assuming that the release name is `wordpress`):
```console
kubectl exec $(kubectl get pods -l app.kubernetes.io/name=wordpress -o jsonpath='{.items[0].metadata.name}') -c wordpress -- wp maintenance-mode activate
kubectl exec $(kubectl get pods -l app.kubernetes.io/name=wordpress -o jsonpath='{.items[1].metadata.name}') -c wordpress -- wp maintenance-mode activate
kubectl exec $(kubectl get pods -l app.kubernetes.io/name=wordpress -o jsonpath='{.items[2].metadata.name}') -c wordpress -- wp maintenance-mode activate
```
### External database support
You may want to have WordPress connect to an external database rather than installing one inside your cluster. Typical reasons for this are to use a managed database service, or to share a common database server for all your applications. To achieve this, the chart allows you to specify credentials for an external database with the [`externalDatabase` parameter](#database-parameters). You should also disable the MariaDB installation with the `mariadb.enabled` option. Here is an example:
```console
mariadb.enabled=false
externalDatabase.host=myexternalhost
externalDatabase.user=myuser
externalDatabase.password=mypassword
externalDatabase.database=mydatabase
externalDatabase.port=3306
```
Refer to the [documentation on using an external database with WordPress](https://docs.bitnami.com/kubernetes/apps/wordpress/configuration/use-external-database/) and the [tutorial on integrating WordPress with a managed cloud database](https://docs.bitnami.com/tutorials/secure-wordpress-kubernetes-managed-database-ssl-upgrades/) for more information.
### Memcached
This chart provides support for using Memcached to cache database queries and objects improving the website performance. To enable this feature, set `wordpressConfigureCache` and `memcached.enabled` parameters to `true`.
When this feature is enabled, a Memcached server will be deployed in your K8s cluster using the Bitnami Memcached chart and the [W3 Total Cache](https://wordpress.org/plugins/w3-total-cache/) plugin will be activated and configured to use the Memcached server for database caching.
It is also possible to use an external cache server rather than installing one inside your cluster. To achieve this, the chart allows you to specify credentials for an external cache server with the [`externalCache` parameter](#database-parameters). You should also disable the Memcached installation with the `memcached.enabled` option. Here is an example:
```console
wordpressConfigureCache=true
memcached.enabled=false
externalCache.host=myexternalcachehost
externalCache.port=11211
```
### Ingress
This chart provides support for Ingress resources. If an Ingress controller, such as nginx-ingress or traefik, that Ingress controller can be used to serve WordPress.
To enable Ingress integration, set `ingress.enabled` to `true`. The `ingress.hostname` property can be used to set the host name. The `ingress.tls` parameter can be used to add the TLS configuration for this host. It is also possible to have more than one host, with a separate TLS configuration for each host. [Learn more about configuring and using Ingress](https://docs.bitnami.com/kubernetes/apps/wordpress/configuration/configure-ingress/).
### TLS secrets
The chart also facilitates the creation of TLS secrets for use with the Ingress controller, with different options for certificate management. [Learn more about TLS secrets](https://docs.bitnami.com/kubernetes/apps/wordpress/administration/enable-tls-ingress/).
### `.htaccess` files
For performance and security reasons, it is a good practice to configure Apache with the `AllowOverride None` directive. Instead of using `.htaccess` files, Apache will load the same directives at boot time. These directives are located in `/opt/bitnami/wordpress/wordpress-htaccess.conf`.
By default, the container image includes all the default `.htaccess` files in WordPress (together with the default plugins). To enable this feature, install the chart with the value `allowOverrideNone=yes`.
[Learn more about working with `.htaccess` files](https://docs.bitnami.com/kubernetes/apps/wordpress/configuration/understand-htaccess/).
## Persistence
The [Bitnami WordPress](https://github.com/bitnami/containers/tree/main/bitnami/wordpress) image stores the WordPress data and configurations at the `/bitnami` path of the container. Persistent Volume Claims are used to keep the data across deployments.
If you encounter errors when working with persistent volumes, refer to our [troubleshooting guide for persistent volumes](https://docs.bitnami.com/kubernetes/faq/troubleshooting/troubleshooting-persistence-volumes/).
### Additional environment variables
In case you want to add extra environment variables (useful for advanced operations like custom init scripts), you can use the `extraEnvVars` property.
```yaml
wordpress:
extraEnvVars:
- name: LOG_LEVEL
value: error
```
Alternatively, you can use a ConfigMap or a Secret with the environment variables. To do so, use the `extraEnvVarsCM` or the `extraEnvVarsSecret` values.
### Sidecars
If additional containers are needed in the same pod as WordPress (such as additional metrics or logging exporters), they can be defined using the `sidecars` parameter. If these sidecars export extra ports, extra port definitions can be added using the `service.extraPorts` parameter. [Learn more about configuring and using sidecar containers](https://docs.bitnami.com/kubernetes/apps/wordpress/configuration/configure-sidecar-init-containers/).
### Pod affinity
This chart allows you to set your custom affinity using the `affinity` parameter. Learn more about Pod affinity in the [kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity).
As an alternative, use one of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the [bitnami/common](https://github.com/bitnami/charts/tree/main/bitnami/common#affinities) chart. To do so, set the `podAffinityPreset`, `podAntiAffinityPreset`, or `nodeAffinityPreset` parameters.

## Notable changes
### 13.2.0
Removed support for limiting auto-updates to WordPress core via the `wordpressAutoUpdateLevel` option. To update WordPress core, we recommend you use the `helm upgrade` command to update your deployment instead of using the built-in update functionality.
### 11.0.0
The [Bitnami WordPress](https://github.com/bitnami/containers/tree/main/bitnami/wordpress) image was refactored and now the source code is published in GitHub in the `rootfs` folder of the container image.
In addition, several new features have been implemented:
- Multisite mode is now supported via `multisite.*` options.
- Plugins can be installed and activated on the first deployment via the `wordpressPlugins` option.
- Added support for limiting auto-updates to WordPress core via the `wordpressAutoUpdateLevel` option. In addition, auto-updates have been disabled by default. To update WordPress core, we recommend to swap the container image version for your deployment instead of using the built-in update functionality.
To enable the new features, it is not possible to do it by upgrading an existing deployment. Instead, it is necessary to perform a fresh deploy.
## Upgrading
### To 14.0.0
This major release bumps the MariaDB version to 10.6. Follow the [upstream instructions](https://mariadb.com/kb/en/upgrading-from-mariadb-105-to-mariadb-106/) for upgrading from MariaDB 10.5 to 10.6. No major issues are expected during the upgrade.
### To 13.0.0
This major release renames several values in this chart and adds missing features, in order to be inline with the rest of assets in the Bitnami charts repository.
- `service.port` and `service.httpsPort` have been regrouped under the `service.ports` map.
- `metrics.service.port` has been regrouped under the `metrics.service.ports` map.
- `serviceAccountName` has been deprecated in favor of `serviceAccount` map.
Additionally updates the MariaDB & Memcached subcharts to their newest major `10.x.x` and `6.x.x`, respectively, which contain similar changes.
### To 12.0.0
WordPress version was bumped to its latest major, `5.8.x`. Though no incompatibilities are expected while upgrading from previous versions, WordPress recommends backing up your application first.
Site backups can be easily performed using tools such as [VaultPress](https://vaultpress.com/) or [All-in-One WP Migration](https://wordpress.org/plugins/all-in-one-wp-migration/).
### To 11.0.0
The [Bitnami WordPress](https://github.com/bitnami/containers/tree/main/bitnami/wordpress) image was refactored and now the source code is published in GitHub in the `rootfs` folder of the container image.
Compatibility is not guaranteed due to the amount of involved changes, however no breaking changes are expected.
### To 10.0.0
[On November 13, 2020, Helm v2 support was formally finished](https://github.com/helm/charts#status-of-the-project), this major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.
[Learn more about this change and related upgrade considerations](https://docs.bitnami.com/kubernetes/apps/wordpress/administration/upgrade-helm3/).
#### Additional upgrade notes
- MariaDB dependency version was bumped to a new major version that introduces several incompatibilities. Therefore, backwards compatibility is not guaranteed unless an external database is used. Check [MariaDB Upgrading Notes](https://github.com/bitnami/charts/tree/main/bitnami/mariadb#to-800) for more information.
- If you want to upgrade to this version from a previous one installed with Helm v3, there are two alternatives:
- Install a new WordPress chart, and migrate your WordPress site using backup/restore tools such as [VaultPress](https://vaultpress.com/) or [All-in-One WP Migration](https://wordpress.org/plugins/all-in-one-wp-migration/).
- Reuse the PVC used to hold the MariaDB data on your previous release. To do so, follow the instructions below (the following example assumes that the release name is `wordpress`).
> Warning: please create a backup of your database before running any of these actions. The steps below would be only valid if your application (e.g. any plugins or custom code) is compatible with MariaDB 10.5.
Obtain the credentials and the name of the PVC used to hold the MariaDB data on your current release:
```console
$ export WORDPRESS_PASSWORD=$(kubectl get secret --namespace default wordpress -o jsonpath="{.data.wordpress-password}" | base64 -d)
$ export MARIADB_ROOT_PASSWORD=$(kubectl get secret --namespace default wordpress-mariadb -o jsonpath="{.data.mariadb-root-password}" | base64 -d)
$ export MARIADB_PASSWORD=$(kubectl get secret --namespace default wordpress-mariadb -o jsonpath="{.data.mariadb-password}" | base64 -d)
$ export MARIADB_PVC=$(kubectl get pvc -l app.kubernetes.io/instance=wordpress,app.kubernetes.io/name=mariadb,app.kubernetes.io/component=primary -o jsonpath="{.items[0].metadata.name}")
```
Upgrade your release (maintaining the version) disabling MariaDB and scaling WordPress replicas to 0:
```console
$ helm upgrade wordpress my-repo/wordpress --set wordpressPassword=$WORDPRESS_PASSWORD --set replicaCount=0 --set mariadb.enabled=false --version 9.6.4
```
Finally, upgrade you release to `10.0.0` reusing the existing PVC, and enabling back MariaDB:
```console
$ helm upgrade wordpress my-repo/wordpress --set mariadb.primary.persistence.existingClaim=$MARIADB_PVC --set mariadb.auth.rootPassword=$MARIADB_ROOT_PASSWORD --set mariadb.auth.password=$MARIADB_PASSWORD --set wordpressPassword=$WORDPRESS_PASSWORD
```
You should see the lines below in MariaDB container logs:
```console
$ kubectl logs $(kubectl get pods -l app.kubernetes.io/instance=wordpress,app.kubernetes.io/name=mariadb,app.kubernetes.io/component=primary -o jsonpath="{.items[0].metadata.name}")
...
mariadb 12:13:24.98 INFO ==> Using persisted data
mariadb 12:13:25.01 INFO ==> Running mysql_upgrade
...
```
### To 9.0.0
The [Bitnami WordPress](https://github.com/bitnami/containers/tree/main/bitnami/wordpress) image was migrated to a "non-root" user approach. Previously the container ran as the `root` user and the Apache daemon was started as the `daemon` user. From now on, both the container and the Apache daemon run as user `1001`. You can revert this behavior by setting the parameters `securityContext.runAsUser`, and `securityContext.fsGroup` to `0`.
Chart labels and Ingress configuration were also adapted to follow the Helm charts best practices.
Consequences:
- The HTTP/HTTPS ports exposed by the container are now `8080/8443` instead of `80/443`.
- No writing permissions will be granted on `wp-config.php` by default.
- Backwards compatibility is not guaranteed.
To upgrade to `9.0.0`, it's recommended to install a new WordPress chart, and migrate your WordPress site using backup/restore tools such as [VaultPress](https://vaultpress.com/) or [All-in-One WP Migration](https://wordpress.org/plugins/all-in-one-wp-migration/).
### To 8.0.0
Helm performs a lookup for the object based on its group (apps), version (v1), and kind (Deployment). Also known as its GroupVersionKind, or GVK. Changing the GVK is considered a compatibility breaker from Kubernetes' point of view, so you cannot "upgrade" those objects to the new GVK in-place. Earlier versions of Helm 3 did not perform the lookup correctly which has since been fixed to match the spec.
In https://github.com/helm/charts/pulls/12642 the `apiVersion` of the deployment resources was updated to `apps/v1` in tune with the API's deprecated, resulting in compatibility breakage.
This major version signifies this change.
### To 3.0.0
Backwards compatibility is not guaranteed unless you modify the labels used on the chart's deployments.
Use the workaround below to upgrade from versions previous to `3.0.0`. The following example assumes that the release name is `wordpress`:
```console
kubectl patch deployment wordpress-wordpress --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'
kubectl delete statefulset wordpress-mariadb --cascade=false
```

## Special input schemas
### ImageRoot
```yaml
registry:
type: string
description: Docker registry where the image is located
example: docker.io
repository:
type: string
description: Repository and image name
example: bitnami/nginx
tag:
type: string
description: image tag
example: 1.16.1-debian-10-r63
pullPolicy:
type: string
description: Specify a imagePullPolicy. Defaults to 'Always' if image tag is 'latest', else set to 'IfNotPresent'
pullSecrets:
type: array
items:
type: string
description: Optionally specify an array of imagePullSecrets (evaluated as templates).
debug:
type: boolean
description: Set to true if you would like to see extra information on logs
example: false
## An instance would be:
# registry: docker.io
# repository: bitnami/nginx
# tag: 1.16.1-debian-10-r63
# pullPolicy: IfNotPresent
# debug: false
```
### Persistence
```yaml
enabled:
type: boolean
description: Whether enable persistence.
example: true
storageClass:
type: string
description: Ghost data Persistent Volume Storage Class, If set to "-", storageClassName: "" which disables dynamic provisioning.
example: "-"
accessMode:
type: string
description: Access mode for the Persistent Volume Storage.
example: ReadWriteOnce
size:
type: string
description: Size the Persistent Volume Storage.
example: 8Gi
path:
type: string
description: Path to be persisted.
example: /bitnami
## An instance would be:
# enabled: true
# storageClass: "-"
# accessMode: ReadWriteOnce
# size: 8Gi
# path: /bitnami
```
### ExistingSecret
```yaml
name:
type: string
description: Name of the existing secret.
example: mySecret
keyMapping:
description: Mapping between the expected key name and the name of the key in the existing secret.
type: object
## An instance would be:
# name: mySecret
# keyMapping:
# password: myPasswordKey
```
#### Example of use
When we store sensitive data for a deployment in a secret, some times we want to give to users the possibility of using theirs existing secrets.
```yaml
# templates/secret.yaml
---
apiVersion: v1
kind: Secret
metadata:
name: {{ include "common.names.fullname" . }}
labels:
app: {{ include "common.names.fullname" . }}
type: Opaque
data:
password: {{ .Values.password | b64enc | quote }}
# templates/dpl.yaml
---
...
env:
- name: PASSWORD
valueFrom:
secretKeyRef:
name: {{ include "common.secrets.name" (dict "existingSecret" .Values.existingSecret "context" $) }}
key: {{ include "common.secrets.key" (dict "existingSecret" .Values.existingSecret "key" "password") }}
...
# values.yaml
---
name: mySecret
keyMapping:
password: myPasswordKey
```
### ValidateValue
#### NOTES.txt
```console
{{- $validateValueConf00 := (dict "valueKey" "path.to.value00" "secret" "secretName" "field" "password-00") -}}
{{- $validateValueConf01 := (dict "valueKey" "path.to.value01" "secret" "secretName" "field" "password-01") -}}
{{ include "common.validations.values.multiple.empty" (dict "required" (list $validateValueConf00 $validateValueConf01) "context" $) }}
```
If we force those values to be empty we will see some alerts
```console
$ helm install test mychart --set path.to.value00="",path.to.value01=""
'path.to.value00' must not be empty, please add '--set path.to.value00=$PASSWORD_00' to the command. To get the current value:
export PASSWORD_00=$(kubectl get secret --namespace default secretName -o jsonpath="{.data.password-00}" | base64 -d)
'path.to.value01' must not be empty, please add '--set path.to.value01=$PASSWORD_01' to the command. To get the current value:
export PASSWORD_01=$(kubectl get secret --namespace default secretName -o jsonpath="{.data.password-01}" | base64 -d)
```
## Upgrading
### To 1.0.0
[On November 13, 2020, Helm v2 support was formally finished](https://github.com/helm/charts#status-of-the-project), this major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.
**What changes were introduced in this major version?**
- Previous versions of this Helm Chart use `apiVersion: v1` (installable by both Helm 2 and 3), this Helm Chart was updated to `apiVersion: v2` (installable by Helm 3 only). [Here](https://helm.sh/docs/topics/charts/#the-apiversion-field) you can find more information about the `apiVersion` field.
- Use `type: library`. [Here](https://v3.helm.sh/docs/faq/#library-chart-support) you can find more information.
- The different fields present in the *Chart.yaml* file has been ordered alphabetically in a homogeneous way for all the Bitnami Helm Charts
**Considerations when upgrading to this version**
- If you want to upgrade to this version from a previous one installed with Helm v3, you shouldn't face any issues
- If you want to upgrade to this version using Helm v2, this scenario is not supported as this version doesn't support Helm v2 anymore
- If you installed the previous version with Helm v2 and wants to upgrade to this version with Helm v3, please refer to the [official Helm documentation](https://helm.sh/docs/topics/v2_v3_migration/#migration-use-cases) about migrating from Helm v2 to v3

# MariaDB packaged by Bitnami
MariaDB is an open source, community-developed SQL database server that is widely in use around the world due to its enterprise features, flexibility, and collaboration with leading tech firms.
[Overview of MariaDB](https://mariadb.org/)
Trademarks: This software listing is packaged by Bitnami. The respective trademarks mentioned in the offering are owned by the respective companies, and use of them does not imply any affiliation or endorsement.
## TL;DR
```bash
$ helm repo add my-repo https://charts.bitnami.com/bitnami
$ helm install my-release my-repo/mariadb
```
## Introduction
This chart bootstraps a [MariaDB](https://github.com/bitnami/containers/tree/main/bitnami/mariadb) replication cluster deployment on a [Kubernetes](https://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
MariaDB is developed as open source software and as a relational database it provides an SQL interface for accessing data. The latest versions of MariaDB also include GIS and JSON features.
Bitnami charts can be used with [Kubeapps](https://kubeapps.dev/) for deployment and management of Helm Charts in clusters.
## Prerequisites
- Kubernetes 1.19+
- Helm 3.2.0+
- PV provisioner support in the underlying infrastructure
## Installing the Chart
To install the chart with the release name `my-release`:
```bash
$ helm install my-release my-repo/mariadb
```
The command deploys MariaDB on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) section lists the parameters that can be configured during installation.
> **Tip**: List all releases using `helm list`
## Uninstalling the Chart
To uninstall/delete the `my-release` deployment:
```bash
$ helm delete my-release
```
The command removes all the Kubernetes components associated with the chart and deletes the release.

Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
```bash
$ helm install my-release \
--set auth.rootPassword=secretpassword,auth.database=app_database \
my-repo/mariadb
```
The above command sets the MariaDB `root` account password to `secretpassword`. Additionally it creates a database named `my_database`.
> NOTE: Once this chart is deployed, it is not possible to change the application's access credentials, such as usernames or passwords, using Helm. To change these application credentials after deployment, delete any persistent volumes (PVs) used by the chart and re-deploy it, or use the application's built-in administrative tools if available.
Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
```bash
$ helm install my-release -f values.yaml my-repo/mariadb
```
> **Tip**: You can use the default [values.yaml](values.yaml)
## Configuration and installation details
### [Rolling VS Immutable tags](https://docs.bitnami.com/containers/how-to/understand-rolling-tags-containers/)
It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.
Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.
### Change MariaDB version
To modify the MariaDB version used in this chart you can specify a [valid image tag](https://hub.docker.com/r/bitnami/mariadb/tags/) using the `image.tag` parameter. For example, `image.tag=X.Y.Z`. This approach is also applicable to other images like exporters.
### Initialize a fresh instance
The [Bitnami MariaDB](https://github.com/bitnami/containers/tree/main/bitnami/mariadb) image allows you to use your custom scripts to initialize a fresh instance. Custom scripts may be specified using the `initdbScripts` parameter. Alternatively, an external ConfigMap may be created with all the initialization scripts and the ConfigMap passed to the chart via the `initdbScriptsConfigMap` parameter. Note that this will override the `initdbScripts` parameter.
The allowed extensions are `.sh`, `.sql` and `.sql.gz`.
These scripts are treated differently depending on their extension. While `.sh` scripts are executed on all the nodes, `.sql` and `.sql.gz` scripts are only executed on the primary nodes. This is because `.sh` scripts support conditional tests to identify the type of node they are running on, while such tests are not supported in `.sql` or `.sql.gz` files.
[Refer to the chart documentation for more information and a usage example](https://docs.bitnami.com/kubernetes/infrastructure/mariadb/configuration/customize-new-instance/).
### Sidecars and Init Containers
If additional containers are needed in the same pod as MariaDB (such as additional metrics or logging exporters), they can be defined using the sidecars parameter.
The Helm chart already includes sidecar containers for the Prometheus exporters. These can be activated by adding the `--set enable-metrics=true` parameter at deployment time. The `sidecars` parameter should therefore only be used for any extra sidecar containers. [See an example of configuring and using sidecar containers](https://docs.bitnami.com/kubernetes/infrastructure/mariadb/configuration/configure-sidecar-init-containers/).
Similarly, additional containers can be added to MariaDB pods using the `initContainers` parameter. [See an example of configuring and using init containers](https://docs.bitnami.com/kubernetes/infrastructure/mariadb/configuration/configure-sidecar-init-containers/).
## Persistence
The [Bitnami MariaDB](https://github.com/bitnami/containers/tree/main/bitnami/mariadb) image stores the MariaDB data and configurations at the `/bitnami/mariadb` path of the container.
The chart mounts a [Persistent Volume](https://kubernetes.io/docs/concepts/storage/persistent-volumes/) volume at this location. The volume is created using dynamic volume provisioning, by default. An existing PersistentVolumeClaim can also be defined.
If you encounter errors when working with persistent volumes, refer to our [troubleshooting guide for persistent volumes](https://docs.bitnami.com/kubernetes/faq/troubleshooting/troubleshooting-persistence-volumes/).
### Adjust permissions of persistent volume mountpoint
As the image run as non-root by default, it is necessary to adjust the ownership of the persistent volume so that the container can write data into it.
By default, the chart is configured to use Kubernetes Security Context to automatically change the ownership of the volume. However, this feature does not work in all Kubernetes distributions.
As an alternative, this chart supports using an initContainer to change the ownership of the volume before mounting it in the final destination. You can enable this initContainer by setting `volumePermissions.enabled` to `true`.
## Troubleshooting
Find more information about how to deal with common errors related to Bitnami's Helm charts in [this troubleshooting guide](https://docs.bitnami.com/general/how-to/troubleshoot-helm-chart-issues).
## Upgrading
It's necessary to set the `auth.rootPassword` parameter when upgrading for readiness/liveness probes to work properly. When you install this chart for the first time, some notes will be displayed providing the credentials you must use under the 'Administrator credentials' section. Please note down the password and run the command below to upgrade your chart:
```bash
$ helm upgrade my-release my-repo/mariadb --set auth.rootPassword=[ROOT_PASSWORD]
```
| Note: you need to substitute the placeholder _[ROOT_PASSWORD]_ with the value obtained in the installation notes.
### To 11.0.0
This major release bumps default MariaDB branch to 10.6. Follow the [official instructions](https://mariadb.com/kb/en/upgrading-from-mariadb-105-to-mariadb-106/) from upgrading between 10.5 and 10.6.
No major issues are expected during the upgrade.
### To 10.0.0
This major release renames several values in this chart and adds missing features, in order to be inline with the rest of assets in the Bitnami charts repository.
Affected values:
- `primary.service.port` was deprecated, we recommend using `primary.service.ports.mysql` instead.
- `primary.service.nodePort` was deprecated, we recommend using `primary.service.nodePorts.mysql` instead.
- `secondary.service.port` was deprecated, we recommend using `secondary.service.ports.mysql` instead.
- `secondary.service.nodePort` was deprecated, we recommend using `secondary.service.nodePorts.mysql` instead.
- `metrics.serviceMonitor.additionalLabels` was deprecated, we recommend using `metrics.serviceMonitor.selector` instead.
- `primary.pdb.enabled` renamed as `primary.pdb.create`.
- `secondary.pdb.enabled` renamed as `secondary.pdb.create`.
- `primary.updateStrategy` changed from String type (previously default to 'rollingUpdate') to Object type, allowing users to configure other updateStrategy parameters, similar to other charts.
- Removed value `primary.rollingUpdatePartition`, now configured using `primary.updateStrategy` setting `primary.updateStrategy.rollingUpdate.partition`.
- `secondary.updateStrategy` changed from String type (previously default to 'rollingUpdate') to Object type, allowing users to configure other updateStrategy parameters, similar to other charts.
- Removed value `secondary.rollingUpdatePartition`, now configured using `secondary.updateStrategy` setting `secondary.updateStrategy.rollingUpdate.partition`.
- `metrics.serviceMonitor.relabellings`, previously used to configure ServiceMonitor metricRelabelings, has been replaced with the value `metrics.serviceMonitor.metricRelabelings`, and new value `metrics.serviceMonitor.relabelings` can be used to set ServiceMonitor relabelings parameter
### To 9.0.0
[On November 13, 2020, Helm v2 support was formally finished](https://github.com/helm/charts#status-of-the-project), this major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.
[Learn more about this change and related upgrade considerations](https://docs.bitnami.com/kubernetes/infrastructure/mariadb/administration/upgrade-helm3/).
### To 8.0.0
- Several parameters were renamed or disappeared in favor of new ones on this major version:
- The terms _master_ and _slave_ have been replaced by the terms _primary_ and _secondary_. Therefore, parameters prefixed with `master` or `slave` are now prefixed with `primary` or `secondary`, respectively.
- `securityContext.*` is deprecated in favor of `primary.podSecurityContext`, `primary.containerSecurityContext`, `secondary.podSecurityContext`, and `secondary.containerSecurityContext`.
- Credentials parameter are reorganized under the `auth` parameter.
- `replication.enabled` parameter is deprecated in favor of `architecture` parameter that accepts two values: `standalone` and `replication`.
- The default MariaDB version was updated from 10.3 to 10.5. According to the official documentation, upgrading from 10.3 should be painless. However, there are some things that have changed which could affect an upgrade:
- [Incompatible changes upgrading from MariaDB 10.3 to MariaDB 10.4](https://mariadb.com/kb/en/upgrading-from-mariadb-103-to-mariadb-104/#incompatible-changes-between-103-and-104).
- [Incompatible changes upgrading from MariaDB 10.4 to MariaDB 10.5](https://mariadb.com/kb/en/upgrading-from-mariadb-104-to-mariadb-105/#incompatible-changes-between-104-and-105).
- Chart labels were adapted to follow the [Helm charts standard labels](https://helm.sh/docs/chart_best_practices/labels/#standard-labels).
- This version also introduces `bitnami/common`, a [library chart](https://helm.sh/docs/topics/library_charts/#helm) as a dependency. More documentation about this new utility could be found [here](https://github.com/bitnami/charts/tree/main/bitnami/common#bitnami-common-library-chart). Please, make sure that you have updated the chart dependencies before executing any upgrade.
Consequences:
Backwards compatibility is not guaranteed. To upgrade to `8.0.0`, install a new release of the MariaDB chart, and migrate the data from your previous release. You have 2 alternatives to do so:
- Create a backup of the database, and restore it on the new release using tools such as [mysqldump](https://mariadb.com/kb/en/mysqldump/).
- Reuse the PVC used to hold the master data on your previous release. To do so, use the `primary.persistence.existingClaim` parameter. The following example assumes that the release name is `mariadb`:
```bash
$ helm install mariadb my-repo/mariadb --set auth.rootPassword=[ROOT_PASSWORD] --set primary.persistence.existingClaim=[EXISTING_PVC]
```
| Note: you need to substitute the placeholder _[EXISTING_PVC]_ with the name of the PVC used on your previous release, and _[ROOT_PASSWORD]_ with the root password used in your previous release.
### To 7.0.0
Helm performs a lookup for the object based on its group (apps), version (v1), and kind (Deployment). Also known as its GroupVersionKind, or GVK. Changing the GVK is considered a compatibility breaker from Kubernetes' point of view, so you cannot "upgrade" those objects to the new GVK in-place. Earlier versions of Helm 3 did not perform the lookup correctly which has since been fixed to match the spec.
In https://github.com/helm/charts/pull/17308 the `apiVersion` of the statefulset resources was updated to `apps/v1` in tune with the api's deprecated, resulting in compatibility breakage.
This major version bump signifies this change.
### To 6.0.0
MariaDB version was updated from 10.1 to 10.3, there are no changes in the chart itself. According to the official documentation, upgrading from 10.1 should be painless. However, there are some things that have changed which could affect an upgrade:
- [Incompatible changes upgrading from MariaDB 10.1 to MariaDB 10.2](https://mariadb.com/kb/en/library/upgrading-from-mariadb-101-to-mariadb-102//#incompatible-changes-between-101-and-102)
- [Incompatible changes upgrading from MariaDB 10.2 to MariaDB 10.3](https://mariadb.com/kb/en/library/upgrading-from-mariadb-102-to-mariadb-103/#incompatible-changes-between-102-and-103)
### To 5.0.0
Backwards compatibility is not guaranteed unless you modify the labels used on the chart's deployments.
Use the workaround below to upgrade from versions previous to 5.0.0. The following example assumes that the release name is mariadb:
```console
$ kubectl delete statefulset opencart-mariadb --cascade=false
```

# Bitnami Common Library Chart
A [Helm Library Chart](https://helm.sh/docs/topics/library_charts/#helm) for grouping common logic between bitnami charts.
## TL;DR
```yaml
dependencies:
- name: common

```
#### Example of use
When we store sensitive data for a deployment in a secret, some times we want to give to users the possibility of using theirs existing secrets.
```yaml
# templates/secret.yaml
---
apiVersion: v1
kind: Secret
metadata:
name: {{ include "common.names.fullname" . }}
labels:
app: {{ include "common.names.fullname" . }}
type: Opaque
data:
password: {{ .Values.password | b64enc | quote }}
# templates/dpl.yaml
---
...
env:
- name: PASSWORD
valueFrom:
secretKeyRef:
name: {{ include "common.secrets.name" (dict "existingSecret" .Values.existingSecret "context" $) }}
key: {{ include "common.secrets.key" (dict "existingSecret" .Values.existingSecret "key" "password") }}
...
# values.yaml
---
name: mySecret
keyMapping:
password: myPasswordKey
```
### ValidateValue
#### NOTES.txt
```console
{{- $validateValueConf00 := (dict "valueKey" "path.to.value00" "secret" "secretName" "field" "password-00") -}}
{{- $validateValueConf01 := (dict "valueKey" "path.to.value01" "secret" "secretName" "field" "password-01") -}}
{{ include "common.validations.values.multiple.empty" (dict "required" (list $validateValueConf00 $validateValueConf01) "context" $) }}
```
If we force those values to be empty we will see some alerts
```console
$ helm install test mychart --set path.to.value00="",path.to.value01=""
'path.to.value00' must not be empty, please add '--set path.to.value00=$PASSWORD_00' to the command. To get the current value:
export PASSWORD_00=$(kubectl get secret --namespace default secretName -o jsonpath="{.data.password-00}" | base64 -d)
'path.to.value01' must not be empty, please add '--set path.to.value01=$PASSWORD_01' to the command. To get the current value:
export PASSWORD_01=$(kubectl get secret --namespace default secretName -o jsonpath="{.data.password-01}" | base64 -d)
```
## Upgrading
### To 1.0.0
[On November 13, 2020, Helm v2 support was formally finished](https://github.com/helm/charts#status-of-the-project), this major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.
**What changes were introduced in this major version?**
- Previous versions of this Helm Chart use `apiVersion: v1` (installable by both Helm 2 and 3), this Helm Chart was updated to `apiVersion: v2` (installable by Helm 3 only). [Here](https://helm.sh/docs/topics/charts/#the-apiversion-field) you can find more information about the `apiVersion` field.
- Use `type: library`. [Here](https://v3.helm.sh/docs/faq/#library-chart-support) you can find more information.
- The different fields present in the *Chart.yaml* file has been ordered alphabetically in a homogeneous way for all the Bitnami Helm Charts
**Considerations when upgrading to this version**
- If you want to upgrade to this version from a previous one installed with Helm v3, you shouldn't face any issues
- If you want to upgrade to this version using Helm v2, this scenario is not supported as this version doesn't support Helm v2 anymore
- If you installed the previous version with Helm v2 and wants to upgrade to this version with Helm v3, please refer to the [official Helm documentation](https://helm.sh/docs/topics/v2_v3_migration/#migration-use-cases) about migrating from Helm v2 to v3

CHART NAME: {{ .Chart.Name }}
CHART VERSION: {{ .Chart.Version }}
APP VERSION: {{ .Chart.AppVersion }}
** Please be patient while the chart is being deployed **
{{- if .Values.diagnosticMode.enabled }}
The chart has been deployed in diagnostic mode. All probes have been disabled and the command has been overwritten with:
command: {{- include "common.tplvalues.render" (dict "value" .Values.diagnosticMode.command "context" $) | nindent 4 }}
args: {{- include "common.tplvalues.render" (dict "value" .Values.diagnosticMode.args "context" $) | nindent 4 }}
Get the list of pods by executing:
kubectl get pods --namespace {{ .Release.Namespace }} -l app.kubernetes.io/instance={{ .Release.Name }}
Access the pod you want to debug by executing
kubectl exec --namespace {{ .Release.Namespace }} -ti <NAME OF THE POD> -- bash
In order to replicate the container startup scripts execute this command:
/opt/bitnami/scripts/mariadb/entrypoint.sh /opt/bitnami/scripts/mariadb/run.sh
{{- else }}
Tip:
Watch the deployment status using the command: kubectl get pods -w --namespace {{ .Release.Namespace }} -l app.kubernetes.io/instance={{ .Release.Name }}
Services:
echo Primary: {{ include "mariadb.primary.fullname" . }}.{{ .Release.Namespace }}.svc.{{ .Values.clusterDomain }}:{{ coalesce .Values.primary.service.ports.mysql .Values.primary.service.port }}
{{- if eq .Values.architecture "replication" }}
echo Secondary: {{ include "mariadb.secondary.fullname" . }}.{{ .Release.Namespace }}.svc.{{ .Values.clusterDomain }}:{{ coalesce .Values.secondary.service.ports.mysql .Values.secondary.service.port }}
{{- end }}
Administrator credentials:
Username: root
Password : $(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "mariadb.secretName" . }} -o jsonpath="{.data.mariadb-root-password}" | base64 -d)
To connect to your database:
1. Run a pod that you can use as a client:
kubectl run {{ include "common.names.fullname" . }}-client --rm --tty -i --restart='Never' --image {{ template "mariadb.image" . }} --namespace {{ .Release.Namespace }} --command -- bash
2. To connect to primary service (read/write):
mysql -h {{ include "mariadb.primary.fullname" . }}.{{ .Release.Namespace }}.svc.{{ .Values.clusterDomain }} -uroot -p {{ .Values.auth.database }}
{{- if eq .Values.architecture "replication" }}
3. To connect to secondary service (read-only):
mysql -h {{ include "mariadb.secondary.fullname" . }}.{{ .Release.Namespace }}.svc.{{ .Values.clusterDomain }} -uroot -p {{ .Values.auth.database }}
{{- end }}
To upgrade this helm chart:
1. Obtain the password as described on the 'Administrator credentials' section and set the 'auth.rootPassword' parameter as shown below:
ROOT_PASSWORD=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "mariadb.secretName" . }} -o jsonpath="{.data.mariadb-root-password}" | base64 -d)
helm upgrade --namespace {{ .Release.Namespace }} {{ .Release.Name }} my-repo/mariadb --set auth.rootPassword=$ROOT_PASSWORD

# Memcached packaged by Bitnami
Memcached is an high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.
[Overview of Memcached](http://memcached.org)
Trademarks: This software listing is packaged by Bitnami. The respective trademarks mentioned in the offering are owned by the respective companies, and use of them does not imply any affiliation or endorsement.
## TL;DR
```console
$ helm repo add my-repo https://charts.bitnami.com/bitnami
$ helm install my-release my-repo/memcached
```
## Introduction
This chart bootstraps a [Memcached](https://github.com/bitnami/containers/tree/main/bitnami/memcached) deployment on a [Kubernetes](https://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
Bitnami charts can be used with [Kubeapps](https://kubeapps.dev/) for deployment and management of Helm Charts in clusters.
## Prerequisites
- Kubernetes 1.19+
- Helm 3.2.0+
## Installing the Chart
To install the chart with the release name `my-release`:
```console
$ helm repo add my-repo https://charts.bitnami.com/bitnami
$ helm install my-release my-repo/memcached
```
These commands deploy Memcached on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) section lists the parameters that can be configured during installation.
> **Tip**: List all releases using `helm list`
## Uninstalling the Chart
To uninstall/delete the `my-release` deployment:
```console
$ helm delete my-release
```
The command removes all the Kubernetes components associated with the chart and deletes the release.

For more information please refer to the [bitnami/memcached](https://github.com/bitnami/containers/tree/main/bitnami/memcached) container image documentation.
Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
```console
$ helm install my-release --set auth.username=user,auth.password=password my-repo/memcached
```
The above command sets the Memcached admin account username and password to `user` and `password` respectively.
> NOTE: Once this chart is deployed, it is not possible to change the application's access credentials, such as usernames or passwords, using Helm. To change these application credentials after deployment, delete any persistent volumes (PVs) used by the chart and re-deploy it, or use the application's built-in administrative tools if available.
Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
```console
$ helm install my-release -f values.yaml my-repo/memcached
```
> **Tip**: You can use the default [values.yaml](values.yaml)
## Configuration and installation details
### [Rolling vs Immutable tags](https://docs.bitnami.com/containers/how-to/understand-rolling-tags-containers/)
It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.
Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.
### Use Sidecars and Init Containers
If additional containers are needed in the same pod (such as additional metrics or logging exporters), they can be defined using the `sidecars` config parameter. Similarly, extra init containers can be added using the `initContainers` parameter.
Refer to the chart documentation for more information on, and examples of, configuring and using [sidecars and init containers](https://docs.bitnami.com/kubernetes/infrastructure/memcached/configuration/configure-sidecar-init-containers/).
### Set Pod affinity
This chart allows you to set your custom affinity using the `affinity` parameter(s). Find more information about Pod affinity in the [Kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity).
As an alternative, you can use the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the [bitnami/common](https://github.com/bitnami/charts/tree/main/bitnami/common#affinities) chart. To do so, set the `podAffinityPreset`, `podAntiAffinityPreset`, or `nodeAffinityPreset` parameters.
## Persistence
When using `architecture: "high-availability"` the [Bitnami Memcached](https://github.com/bitnami/containers/tree/main/bitnami/memcached) image stores the cache-state at the `/cache-state` path of the container if enabled.
Persistent Volume Claims (PVCs) are used to keep the data across deployments. This is known to work in GCE, AWS, and minikube.
See the [Parameters](#parameters) section to configure the PVC or to disable persistence.
If you encounter errors when working with persistent volumes, refer to our [troubleshooting guide for persistent volumes](https://docs.bitnami.com/kubernetes/faq/troubleshooting/troubleshooting-persistence-volumes/).
## Troubleshooting

## Upgrading
### To 5.0.0
This major release renames several values in this chart and adds missing features, in order to be inline with the rest of assets in the Bitnami charts repository.
Some affected values are:
- `memcachedUsername` and `memcachedPassword` have regrouped under the `auth` map.
- `arguments` has been renamed to `args`.
- `extraEnv` has been renamed to `extraEnvVars`.
- `service.port`, `service.internalPort` and `service.externalPort` have been regrouped under the `service.ports` map.
- `metrics.kafka.service.port` has been regrouped under the `metrics.kafka.service.ports` map.
- `metrics.jmx.service.port` has been regrouped under the `metrics.jmx.service.ports` map.
- `updateStrategy` (string) and `rollingUpdatePartition` are regrouped under the `updateStrategy` map.
### To 5.3.0
This version introduces `bitnami/common`, a [library chart](https://helm.sh/docs/topics/library_charts/#helm) as a dependency. More documentation about this new utility could be found [here](https://github.com/bitnami/charts/tree/main/bitnami/common#bitnami-common-library-chart). Please, make sure that you have updated the chart dependencies before executing any upgrade.
### To 5.0.0
[On November 13, 2020, Helm v2 support formally ended](https://github.com/helm/charts#status-of-the-project). This major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.
[Learn more about this change and related upgrade considerations](https://docs.bitnami.com/kubernetes/infrastructure/memcached/administration/upgrade-helm3/).
### To 4.0.0
Backwards compatibility is not guaranteed unless you modify the labels used on the chart's deployments.
Use the workaround below to upgrade from versions previous to 4.0.0. The following example assumes that the release name is memcached:
```console
$ kubectl delete deployment memcached --cascade=false
$ helm upgrade memcached my-repo/memcached
```
### To 3.0.0
This release uses the new bash based `bitnami/memcached` container which uses bash scripts for the start up logic of the container and is smaller in size.
### To 1.0.0
Backwards compatibility is not guaranteed unless you modify the labels used on the chart's deployments.
Use the workaround below to upgrade from versions previous to 1.0.0. The following example assumes that the release name is memcached:
```console
$ kubectl patch deployment memcached --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'
```

# password: myPasswordKey
```
#### Example of use
When we store sensitive data for a deployment in a secret, some times we want to give to users the possibility of using theirs existing secrets.
```yaml
# templates/secret.yaml
---
apiVersion: v1
kind: Secret
metadata:
name: {{ include "common.names.fullname" . }}
labels:
app: {{ include "common.names.fullname" . }}
type: Opaque
data:
password: {{ .Values.password | b64enc | quote }}
# templates/dpl.yaml
---
...
env:
- name: PASSWORD
valueFrom:
secretKeyRef:
name: {{ include "common.secrets.name" (dict "existingSecret" .Values.existingSecret "context" $) }}
key: {{ include "common.secrets.key" (dict "existingSecret" .Values.existingSecret "key" "password") }}
...
# values.yaml
---
name: mySecret
keyMapping:
password: myPasswordKey
```
### ValidateValue
#### NOTES.txt
```console
{{- $validateValueConf00 := (dict "valueKey" "path.to.value00" "secret" "secretName" "field" "password-00") -}}
{{- $validateValueConf01 := (dict "valueKey" "path.to.value01" "secret" "secretName" "field" "password-01") -}}
{{ include "common.validations.values.multiple.empty" (dict "required" (list $validateValueConf00 $validateValueConf01) "context" $) }}
```
If we force those values to be empty we will see some alerts
```console
$ helm install test mychart --set path.to.value00="",path.to.value01=""
'path.to.value00' must not be empty, please add '--set path.to.value00=$PASSWORD_00' to the command. To get the current value:
export PASSWORD_00=$(kubectl get secret --namespace default secretName -o jsonpath="{.data.password-00}" | base64 -d)
'path.to.value01' must not be empty, please add '--set path.to.value01=$PASSWORD_01' to the command. To get the current value:
export PASSWORD_01=$(kubectl get secret --namespace default secretName -o jsonpath="{.data.password-01}" | base64 -d)
```
## Upgrading
### To 1.0.0
[On November 13, 2020, Helm v2 support was formally finished](https://github.com/helm/charts#status-of-the-project), this major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.
**What changes were introduced in this major version?**
- Previous versions of this Helm Chart use `apiVersion: v1` (installable by both Helm 2 and 3), this Helm Chart was updated to `apiVersion: v2` (installable by Helm 3 only). [Here](https://helm.sh/docs/topics/charts/#the-apiversion-field) you can find more information about the `apiVersion` field.
- Use `type: library`. [Here](https://v3.helm.sh/docs/faq/#library-chart-support) you can find more information.
- The different fields present in the *Chart.yaml* file has been ordered alphabetically in a homogeneous way for all the Bitnami Helm Charts
**Considerations when upgrading to this version**
- If you want to upgrade to this version from a previous one installed with Helm v3, you shouldn't face any issues
- If you want to upgrade to this version using Helm v2, this scenario is not supported as this version doesn't support Helm v2 anymore
- If you installed the previous version with Helm v2 and wants to upgrade to this version with Helm v3, please refer to the [official Helm documentation](https://helm.sh/docs/topics/v2_v3_migration/#migration-use-cases) about migrating from Helm v2 to v3
