Add volume to mongoDB Percona operator

Question

I'm trying to add Filebeat container to the rs0 StatefulSet to collect the logs of my mongoDB. I added a filebeat sidecar container to the operator (according to the docs), and now I'm stuck. How can I create an emptyDir volume that would be mounted and accessible on both the mongod container and the filebeat container?

The percona guys helped my find a solution, a bit of a hack but it worked for me

you can't create a new volume for the mongod container but you can map one of the existing volumes to the sidecar container, for example:

sidecars:
- image: ...
  command: ...
  args: ...
  name: rs-sidecar-1
  volumeMounts:
    - mountPath: /mytmp
      name: mongod-data
