Share mount namespace with a privileged pod

Question

I am trying to get the mount point details of host from a kuberentes pod. It is a privileged container. Even if I mount the root file system , I am not able to check the mount details of a particular type say s3fsmay be because it belongs to a different namespace. What is the best way to share the mount point namespace.

Answer 1

I did some research and found that kubernetes provides an option called MountPropagation which helps to achieve my requirement.

I tested this feature in my local set up and it did give me the result I wanted.

Few links that I found useful:
