Installation

Keldon can be installed in several ways depending on your environment and preferences. We recommend Helm for production deployments because it makes upgrades predictable.

Helm (recommended)

Add the chart repository and install:

helm repo add cnb https://charts.keldon.io
helm repo update

helm install cnb cnb/keldon \
  --namespace cnb-system \
  --create-namespace

Raw manifests

If you prefer a plain manifest, apply the released YAML directly:

kubectl apply --server-side -f \
  https://releases.keldon.io/operator/v1.24.0.yaml

Verify the installation

After installation, confirm the operator is healthy:

kubectl get deploy -n cnb-system
kubectl get crds | grep cnb.io

You should see the Cluster, Backup, ScheduledBackup, and Pooler CRDs registered.

Upgrading

Helm handles upgrades transparently:

helm upgrade cnb cnb/keldon --namespace cnb-system

The operator performs a rolling update and does not interrupt running clusters.

Uninstalling

Removing the operator does not delete your data. Cluster CRs and PVCs remain until you explicitly delete them.

helm uninstall cnb --namespace cnb-system
