删除名称空间并删除头盔部署？

Question

I deploy my helm deploys to isolated namespaces

Deleting a namespace deletes all the resources in it- except the helm deployment

Deleting a helm deployment deletes all resource in it- except the namespace

I have to do this which seems redundant:

helm del `helm ls NAMESPACE --short` --purge
kubectl delete namespace NAMESPACE

Id rather just delete my namespace and have the helm deploy also purged- is this possible?

Answer 1

Deleting a namespace deletes all the resources in it- except the helm deployment

This can't be (deleting a namespace implies deleting everything in it, there aren't any exceptions), and must means that the state representing Helm's concept of a deployment doesn't live in that namespace. Helm stores these as config maps in the TILLER_NAMESPACE . See here and here .

It's not surprising that if you create some resources with helm and then go "under the hood" and delete those resources directly via kubectl , Helm's state of the world won't result in that deployment disappearing.

Deleting a helm deployment deletes all resource in it- except the namespace

That sounds like expected behaviour. Presumably you created the namespace out of band with kubectl , it's not part of your Helm deployment. So deleting the Helm deployment wouldn't delete that namespace.

If you kubectl create namespace NS and helm install CHART --namespace NS then it's not surprising that to clean up, you need to helm delete the release and then kubectl delete the namespace.

The only way I could imagine to do that would be for the Helm chart itself to both create a namespace and create all subsequent namespace-scoped resources within that namespace. Here is an example that appears to do such a thing.

Answer 2

There is a PR created to cleanup all resources deployed from helm. follow the link --> https://github.com/helm/helm/issues/1464

hopefully in the future release it will be addressed
