You can address your requirement using one of the below option

  1. use the two containers in the same pod. that way both the containers can share the volume
  2. Use NFS or some other persistent storage that supports ReadWriteMany. That way multiple pods can share same volume

To leverage shared storage for use by two separate containers (in two independent pods) configure PV of type NFS, or other shared storage such as GlusterFS etc.

A basic example using NFS available here Sharing an NFS Persistent Volume (PV) Across Two Pods
