+# GitLab Job Runner Operator
+
+Kubernetes operator for executing code from GitLab repositories as one-time Jobs or scheduled CronJobs.
+
+## Features
+
+- Execute scripts from GitLab repositories as Kubernetes Jobs
+- Schedule recurring executions using CronJobs
+- Secure credential management through Kubernetes Secrets
+- Support for custom container images and service accounts
+- Automatic cleanup with finalizers
+
+## Architecture
+
+The operator watches for `GitlabJobRunner` custom resources and:
+
+1. Clones the specified GitLab repository using credentials from a Secret
+2. Creates either a Job (one-time) or CronJob (scheduled) based on the spec
+3. Executes the specified script from the repository
+4. Manages lifecycle and status updates
+
+## Prerequisites
+
+- Kubernetes cluster (1.24+)
+- kubectl configured
+- GitLab repository with scripts
+- GitLab access token with read permissions
+
+## Installation
+
+### Using Helm (Recommended)
+
+```bash
+# Install from local chart
+helm install gitlab-job-runner ./helm/gitlab-job-runner \
+  --namespace gitlab-job-runner-system \
+  --create-namespace
+
+# Or with custom values
+helm install gitlab-job-runner ./helm/gitlab-job-runner \
+  --namespace gitlab-job-runner-system \
+  --create-namespace \
+  --set image.repository=your-registry/gitlab-job-runner \
+  --set image.tag=0.1.0
+```
+
+### Using Make
+
+```bash
+# Apply CRDs
+make install
+
+# Deploy operator
+make deploy IMG=your-registry/gitlab-job-runner:latest
+```
+
+### Create GitLab Credentials Secret
+
+```bash
+kubectl create secret generic gitlab-credentials \
+  --from-literal=GITLAB_URL=https://gitlab.example.com \
+  --from-literal=GITLAB_TOKEN=glpat-xxxxxxxxxxxxxxxxxxxx
+```
+
+### Create Service Account for Script Execution
+
+If your scripts need to interact with Kubernetes API:
+
+```bash
+kubectl apply -f config/samples/example_serviceaccount.yaml
+```
+
+## Usage
+
+### One-time Job Example
+
+```yaml
+apiVersion: batch.rml.ru/v1alpha1
+kind: GitlabJobRunner
+metadata:
+  name: cleanup-job
+spec:
+  gitlabSecretRef: gitlab-credentials
+  repositoryURL: mygroup/myrepo
+  branch: main
+  scriptPath: scripts/cleanup.sh
+  serviceAccountName: backup-sa
+```
+
+### CronJob Example
+
+```yaml
+apiVersion: batch.rml.ru/v1alpha1
+kind: GitlabJobRunner
+metadata:
+  name: backup-cronjob
+spec:
+  schedule: "0 2 * * *"
+  gitlabSecretRef: gitlab-credentials
+  repositoryURL: mygroup/myrepo
+  branch: main
+  scriptPath: scripts/backup.sh
+  serviceAccountName: backup-sa
+  suspend: false
+  concurrencyPolicy: Forbid
+```

+- Use `#!/bin/sh` or `#!/bin/bash` shebang
+- Have kubectl binary available (uses `bitnami/kubectl:latest` image)
+- Use service account permissions for Kubernetes operations
+
+### Example Script
+
+```bash
+#!/bin/bash
+set -e
+
+# Wait for resource deletion
+kubectl delete deployment old-app --ignore-not-found=true
+kubectl wait --for=delete deployment/old-app --timeout=300s
+
+# Apply new resources
+kubectl apply -f manifests/new-app.yaml
+kubectl wait --for=condition=available deployment/new-app --timeout=300s
+
+echo "Deployment complete"
+```
+
+## Development
+
+### Prerequisites
+
+- Go 1.24+
+- Kubebuilder
+- Docker
+
+### Build
+
+```bash
+# Generate CRDs and manifests
+make generate
+make manifests
+
+# Build operator image
+make docker-build IMG=your-registry/gitlabjobrunner-operator:latest
+
+# Push image
+make docker-push IMG=your-registry/gitlabjobrunner-operator:latest
+```
+
+### Testing
+
+```bash
+# Run tests
+make test
+
+# Run e2e tests
+make test-e2e
+```
+
+## Monitoring
+
+The operator exposes metrics on port 8443 (HTTPS) by default:
+
+- Custom resource reconciliation metrics
+- Job/CronJob creation status
+- GitLab access errors
+
+## Security Considerations
+
+1. **GitLab Token**: Store in Kubernetes Secret, use read-only tokens with minimal scope
+2. **Service Account**: Grant only necessary permissions for script operations
+3. **Network Policies**: Restrict pod network access if needed
+4. **Image Security**: Use trusted container images, enable image scanning
+
+## Troubleshooting
+
+### Check Operator Logs
+
+```bash
+kubectl logs -n cronjob-restore-system deployment/cronjob-restore-controller-manager
+```
+
+### Check Job/CronJob Status
+
+```bash
+kubectl get jobs,cronjobs
+kubectl describe job <job-name>
+```
+
+### Check GitlabJobRunner Status
+
+```bash
+kubectl get gitlabjobrunner
+kubectl describe gitlabjobrunner <name>
+```
+
+### Common Issues
+
+- **Git clone fails**: Verify GitLab credentials in Secret
+- **Script not found**: Check repositoryURL, branch, and scriptPath
+- **Permission denied**: Ensure ServiceAccount has necessary RBAC permissions
+- **CronJob not triggering**: Verify schedule syntax and suspend field
