How to remove PVC resource permanently.

203

 

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 list

 

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

List of Helm Charts Installed.
List of Helm Charts Installed.

 

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

Uninstall the helm chart

Simply use this name to uninstall the helm chart.

 

 helm uninstall  sumit36718160

 

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