Helm 3 install for resouces that exist
when running helm install (helm 3.0.2)
I got the following error: Error:
rendered manifests contain a resource that already exists. Unable to continue with install: existing resource conflict: kind: PodSecurityPolicy, namespace: , name: po-kube-state-metrics
But I don't find it and also In the error im not getting the ns, How can I remove it ?
when running kubectl get all --all-namespaces I see all the resources but not the po-kub-state-metrics ... it also happen to other resources, any idea?
I got the same error to: monitoring-grafana entity and the result of
kubectl get PodSecurityPolicy --all-namespaces is:
monitoring-grafana false RunAsAny RunAsAny RunAsAny RunAsAny false configMap,emptyDir,projected,secret,do
Answer
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 -
