Hello,

In order for you to get root access to the container that is running inside a pod on the Managed Kubernetes cluster, your container needs to be running as the root user.

What you could do instead is, while building your Docker image you could install the unzip command, that way it would be available once you start the container. To do that you just need to add the following to your Dockerfile:

RUN apt update -y && \
apt install unzip -y

Hope that this helps!

Bobby

Another approach you could take to not affect your image would be to have it already extracted locally to some dir locally, then use kubectl cp command to copy the contents of that directory to the pod.

I do want to point out that unless where you’re copying the data to is backed by persistent storage all data copied to a pod will be lost on a container restart.
