First of all you need to make sure you’ve successfully uninstalled the helm release, before reinstalling.
To list all the releases, use:
$ helm list --all --all-namespaces
To uninstall a release, use:
$ helm uninstall <release-name> -n <namespace>
You can also use --no-hooks to skip running hooks for the command:
$ helm uninstall <release-name> -n <namespace> --no-hooks
If uninstalling doesn’t solve your problem, you can try the following command to cleanup:
$ helm template <NAME> <CHART> --namespace <NAMESPACE> | kubectl delete -f -
Sample:
$ helm template happy-panda stable/mariadb --namespace kube-system | kubectl delete -f -
Now, try installing again.
Update:
Let’s consider that your chart name is mon and your release name is po. Since you are in the charts directory (.) like below:
.
├── mon
│ ├── Chart.yaml
│ ├── README.md
│ ├── templates
│ │ ├── one.yaml
│ │ ├── two.yaml
│ │ ├── three.yaml
│ │ ├── _helpers.tpl
│ │ ├── NOTES.txt
│ └── values.yaml
Then you can skip the helm repo name (i.e. stable) in the helm template command. Helm will use your mon chart from the directory.
$ helm template po mon --namespace mon | kubectl delete -f -
