How to remove PVC resource permanently.

In this article, we will release all the resources allocated to our Kubernetes container pod: not only GPU, CPU, and memory resources but we also free the PVC storage as well. So, make sure you copy all your data to the local drive before releasing PVC storage as well.

We have already learned how to release GPU, CPU, and memory resources by uninstalling the existing helm chart. For your convenience, we will repeat the steps again.

Steps

Uninstall the helm chart

Always remember to switch to the kubernetes icekube context

kubectl config set-context icekube --namespace=ltu-default
                   OR
kubectl config use-context icekube 
kubectl config set-context --current --namespace=ltu-default

List all the helm chart

To list all the helm chart current installed on the system just simply type the below command.

helm lists

It will simply list all the helm charts installed on the system.

You can see from the above output, that it is the name which we used the first name with a unique 8 integer digit.

Uninstall the helm chart

Simply use this name to uninstall the helm chart.

 helm uninstall  sumit49670241

Once you issue the helm uninstall command with the chart name. It will simply release all the resources except PVC, the storage. Thus, your data remains safe.

Deleting the PVC storage 

To delete the PVC storage you have to login to the ice.ri.se web portal, on the front page click on the Experimental Kubernetes cluster as shown below.

Then click on Rancher GUI

Then click on “Login with Keycloak”

From the below screenshot choose Global->icekube->ltu

Now clock on the “Volumes” tab and search for your volume name in the search bar.
