I want to delete all the files under the volume directory. The directory is inside the Kubernetes pod. So I am using the exec command.
My command -
kubectl exec $POD -- rm -rf /usr/local/my-app/volume/*The above command is not working. No output of the above command on terminal. I tried with below command and it is working -
kubectl exec $POD -- rm -rf /usr/local/my-app/volumeBut it will delete the directory. I can't delete the directory because it is using for mounting purpose.
How can I achieve the above functionalities?
Thanks
That's because the wildcard expansion is happening on your machine and not the Pod; what you want is to have the shell glob expand on the Pod, which one can accomplish via
kubectl exec $POD -- sh -c 'rm -rf /usr/local/my-app/volume/*'
