Limit helm history

[Luscha]

As the cluster grow we need to ensure that helm do not retain all version's resources (secrets, configmaps, ...)

You can tell Helm to keep only a certain number of revisions by setting --history-max during installation or upgrade:

helm upgrade --install <release-name> <chart-path> -n <namespace> --history-max 5

This ensures that Helm retains only the last 5 revisions, deleting older ones automatically.

You can also update an existing release with:

helm upgrade <release-name> <chart-path> -n <namespace> --history-max 5

---

Delete Old Revisions Manually

kubectl delete secret -n <namespace> $(kubectl get secrets -n <namespace> | grep 'sh.helm.release' | awk '{print $1}')
