Installation

important

  1. The plugin must be installed in the same namespace as the CloudNativePG operator (typically cnpg-system).

  2. Keep in mind that the operator's listening namespaces may differ from its installation namespace. Double-check this to avoid configuration issues.

Verifying the Requirements​

Before installing the plugin, make sure the requirements are met.

CloudNativePG Version​

Ensure you're running a version of CloudNativePG that is compatible with the plugin. If installed in the default cnpg-system namespace, you can verify the version with:

kubectl get deployment -n cnpg-system cnpg-controller-manager -o yaml \
  | grep ghcr.io/cloudnative-pg/cloudnative-pg

Example output:

image: ghcr.io/cloudnative-pg/cloudnative-pg:1.26.0

The version must be 1.26 or newer.

cert-manager​

Use the cmctl tool to confirm that cert-manager is installed and available:

cmctl check api

Example output:

The cert-manager API is ready

Both checks are required before proceeding with the installation.

Installing the Barman Cloud Plugin​

Install the plugin using kubectl by applying the manifest for the latest release:

kubectl apply -f \
  https://github.com/cloudnative-pg/plugin-barman-cloud/releases/download/v0.4.0/manifest.yaml

Example output:

customresourcedefinition.apiextensions.k8s.io/objectstores.barmancloud.cnpg.io created
serviceaccount/plugin-barman-cloud created
role.rbac.authorization.k8s.io/leader-election-role created
clusterrole.rbac.authorization.k8s.io/metrics-auth-role created
clusterrole.rbac.authorization.k8s.io/metrics-reader created
clusterrole.rbac.authorization.k8s.io/objectstore-editor-role created
clusterrole.rbac.authorization.k8s.io/objectstore-viewer-role created
clusterrole.rbac.authorization.k8s.io/plugin-barman-cloud created
rolebinding.rbac.authorization.k8s.io/leader-election-rolebinding created
clusterrolebinding.rbac.authorization.k8s.io/metrics-auth-rolebinding created
clusterrolebinding.rbac.authorization.k8s.io/plugin-barman-cloud-binding created
secret/plugin-barman-cloud-8tfddg42gf created
service/barman-cloud created
deployment.apps/barman-cloud configured
certificate.cert-manager.io/barman-cloud-client created
certificate.cert-manager.io/barman-cloud-server created
issuer.cert-manager.io/selfsigned-issuer created

Finally, check that the deployment is up and running:

kubectl rollout status deployment \
  -n cnpg-system barman-cloud

Example output:

deployment "barman-cloud" successfully rolled out

This confirms that the plugin is deployed and ready to use.

Testing the latest development snapshot​

You can also test the latest development snapshot of the plugin with the following command:
