PVCs will not mount in 0.12.21

Bug

Current Behavior

After upgrading from 0.12.16 to 0.12.21 our PVCs are no longer mounting as expected. We are receiving the following error:

Failed getting status for service 'cache-volume' (from module 'cache-volume'). Here is the output:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
persistentvolumeclaim module cache-volume doesn't specify a serviceResource in its configuration. You must specify a resource in the module config in order to use certain Garden features, such as hot
reloading, tasks and tests.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

serviceResource isn’t mentioned in the current PVC docs

Unfortunately Homebrew has made it incredibly difficult to rollback to a previous version of a package.

Our current PVC config is

kind: Module
name: cache-volume
type: persistentvolumeclaim
include: []
spec:
  accessModes: [ReadWriteMany]
  resources:
    requests:
      storage: 128Mi

and the volume config is

- name: cache
  containerPath: /app/cache
  module: cache-volume

EDIT: the volume is used in a container module running in a local-kubernetes provider.

Expected behavior

PVCs mount as expected OR the docs are updated to reflect the serviceResource config requirement.

Reproducible example

Create a simple volume and create a PVC module for that volume without serviceResource specified.

Workaround

None so far

Suggested solution(s)

If serviceResource is required for PVC modules now a doc update would be sufficient.

Aha, ok. We tried reproducing this on our end but came up short. Any pointers, @edvald?

And thanks for the offer @ultimatemonty, I’ll definitely reach out if we find ourselves blocked, but this should be an easy enough fix.

Awesome, thanks for the repro. This will make it a lot easier to diagnose and fix.
