Description

If a devworkspace uses per-workspace storage, has mountSources: true but has no volumes defined, the calculated PVC size will erroneously be 0.

How To Reproduce

  1. Apply the following devworkspace that has no volumes & uses per-workspace storage:
kind: DevWorkspace
apiVersion: workspace.devfile.io/v1alpha2
metadata:
  name: plain-per-workspace
spec:
  started: true
  routingClass: 'basic'
  template:
    attributes:
        controller.devfile.io/storage-type: per-workspace
    components:
      - name: web-terminal
        container:
          image: quay.io/wto/web-terminal-tooling:next
          memoryRequest: 256Mi
          memoryLimit: 512Mi
          mountSources: true
          command:
           - "tail"
           - "-f"
           - "/dev/null"
  1. The DevWorkspace will fail with the following error:
Error provisioning storage: Failed to sync storage-workspace8723f4cb2dfa4922 PVC to cluster: PersistentVolumeClaim "storage-workspace8723f4cb2dfa4922" is invalid: spec.resources[storage]: Invalid value: "0": must be greater than zero

Expected behavior

If a devworkspace which does not define any volumes but has mountSources enabled, then the default PVC size should be used when using the per-workspace storage strategy.

fix: Use at least minimum PVC size when mountSources used
2416989 
Fix devfile#1239

This commit fixes an edge case where a devworkspace that has no volume components,
but has a container component with mountSources enabled will request a PVC size of 0
when using the per-workspace storage strategy.

When mountSources are used, the devworkspace requires storage to store the project sources.
However, it is unknown how much storage is actually required for the project sources.
Thus, we treat container components with mountSources enabled as if they were volume components
with an unspecified size.
