## Source

- Helm chart: `cloudnative-pg` from https://cloudnative-pg.github.io/charts

# Trigger a sync
argocd app sync cloudnative-pg

# View deployment history
argocd app history cloudnative-pg
```

## Verification

```bash
# Check operator pod is running
kubectl get pods -n cnpg-system

# Check operator logs
kubectl logs -n cnpg-system -l app.kubernetes.io/name=cloudnative-pg

```
