https://github.com/devfile/devworkspace-operator/issues/1257

Is it tested? How?

1. Deploy DWO:

   export DWO_IMG=quay.io/dkwon17/devworkspace-controller:init-container-mount
   make install

2. In the DWOC named devworkspace-operator-config, enable persistent storage.

   apiVersion: controller.devfile.io/v1alpha1
   kind: DevWorkspaceOperatorConfig
   metadata:
   name: devworkspace-operator-config
   namespace: eclipse-che
   config:
   workspace:
   persistUserHome:
     enabled: true

3. Create a configmap that mounts to any directory:

   kind: ConfigMap
   apiVersion: v1
   metadata:
   name: storageconf
   labels:
   controller.devfile.io/mount-to-devworkspace: 'true'
   controller.devfile.io/watch-configmap: 'true'
   annotations:
   controller.devfile.io/mount-as: subpath
   controller.devfile.io/mount-path: /home/user/.config/containers
   data:
   storage.conf: test1234

4. Create a workspace and wait for it to start:

   oc apply -f ./samples/code-latest.yaml

5. Verify that the first initcontainer is init-persistent-home, and that the configmap is mounted in all containers except for init-persistent-home:

   
   $ oc get pod <pod name> -o jsonpath='{.spec.initContainers[0].name}'
   init-persistent-home

$ oc get pod -o jsonpath='{.spec.initContainers[0].volumeMounts}' | grep storageconf // no match exists

$ oc get pod -o jsonpath='{.spec.initContainers[1].volumeMounts}' | grep storageconf // match exists

$ oc get pod -o jsonpath='{.spec.initContainers[2].volumeMounts}' | grep storageconf // match exists

$ oc get pod -o jsonpath='{.spec.containers[*].volumeMounts}' | grep storageconf // match exists

6. Verify that stow has run successfully in the `dev` container:

sh-4.4$ cat ~/.stow.log | tail -n 10 LINK: go/pkg/mod/mvdan.cc/xurls/v2@v2.5.0/xurls_test.go => ../../../../../../../tooling/go/pkg/mod/mvdan.cc/xurls/v2@v2.5.0/xurls_test.go level of go/pkg/sumdb is 2 MKDIR: go/pkg/sumdb level of go/pkg/sumdb/sum.golang.org is 3 MKDIR: go/pkg/sumdb/sum.golang.org level of go/pkg/sumdb/sum.golang.org/latest is 4 LINK: go/pkg/sumdb/sum.golang.org/latest => ../../../../../tooling/go/pkg/sumdb/sum.golang.org/latest Planning stow of package .... done Processing tasks...

Hello @AObuchow could you please take a look? I just want to make sure the code is OK before I add new tests

@dkwon17 In the testing instructions, you said to grep for my-settings instead of storageconf: oc get pod <pod name> -o jsonpath='{.spec.containers[*].volumeMounts}' | grep my-settings. Was that intentional?

[dkwon17]

@AObuchow sorry that was a mistake, it should be storageconf

[AObuchow]

@dkwon17 also before merging please squash your fixup commits & mention in the "Add test" commit that the tests are related to automount functionality with home persistence.
