Title:
Create Backup of pods and then restore the backup with all Pod, which has labels, app =
nginx
Issue/Feature Description:
Test Case Precondition

1. Kahu project installed in given name-space (test-kahu)
2. All below pods should be up and running:
   a. backup service
   b. Meta service with nfs provider
   c. nfs-server
3. Metadata location is created already
4. Namespace test-ns is created and contains some of the kubernetes resources
   5.Namespace restore-ns is created
   Test Case steps:
5. Create below backup CR using kubectl command
   (use kubectl create -f <backup.yaml>)
   apiVersion: kahu.io/v1
   kind: Backup
   metadata:
   name: backup-Kahu-0001
   spec:
   includeNamespaces: [test-ns]
   metadataLocation: nfs
   includeResources:

• name:
  kind: Pod
  isRegex: true

2. Use kubectl describe backup -n test-kahu
3. Get inside nfs server pod and check for the content inside mount path given
   (use command kubectl exec -ti -n test-kahu /bin/sh)
4. Create a restore CR on new namespace (restore-ns)
   apiVersion: kahu.io/v1
   kind: Restore
   metadata:
   name: restore-Kahu-0001
   Spec:
   backupName: backup-Kahu-0001
   namespaceMapping:
   test-ns : restore-ns
   label:
   matchLabels:
   app: nginx
   includeResources:

• name:
• kind: Pod
  isRegex: true
  Expected Result:

1. In step 2,
   a) Verify that backup stage is Finished and State is Completed
   b) Verify the resource list in status shows all the required resources
2. In step 3, verify that
   a) tar file is created with name of backup
   b) After untar file, All pods are backuped.
3. In step4, verify that
   a) Backed up pods only with labels, app = nginx in its name are up in new namespace
   restore-ns
   Why this issue to fixed / feature is needed(give scenarios or use cases):
   This is a testcase which is to automated to make sure deployment is properly backed up and
   restored
