--------------------------------------
Since helm doesn't automatically delete the crds, I'm closing this issue for
now.

> Helm charts deletion won't delete CRD and may have CRD object leaked

> Key: SUBMARINE-644
> URL: https://issues.apache.org/jira/browse/SUBMARINE-644

> Issue Type: Improvement
> Components: Backend Server
> Reporter: Zhankun Tang
> Assignee: Wanqiang Ji
> Priority: Major

> There're a bunch of issues in helm charts found:
> 1. If the user has CRD "tfjobs.kubeflow.org",
> "podgroups.scheduling.incubator.k8s.io", "pytorchjobs.kubeflow.org" already
> exists in K8s cluster. It will report below errors:
> {code:java}
> $ helm install submarine ./helm-charts/submarine
> Error: rendered manifests contain a resource that already exists. Unable to
> continue with install: existing resource conflict: namespace: , name:
> podgroups.scheduling.incubator.k8s.io, existing_kind:
> apiextensions.k8s.io/v1beta1, Kind=CustomResourceDefinition, new_kind:
> apiextensions.k8s.io/v1beta1, Kind=CustomResourceDefinition
> {code}
> Delete the crd like this will resolve this issue:
> kubectl delete crd/tfjobs.kubeflow.org && kubectl delete
> crd/podgroups.scheduling.incubator.k8s.io && kubectl delete
> crd/pytorchjobs.kubeflow.org
> 2. helm delete won't delete all resources created by submarine. Like tfjob,
> pytorchjob, notebook, and ingress. We should clean up these CRD objects when
> uninstallation. Otherwise, the user can only delete the whole k8s namespace
> to clean up the pod.
> 3. We should make the CRD scope to "namespace" scope and delete them when
> uninstallation.
