Is an AWXRestore with PVC only possible? (without the AWXBackup resource)

Get Help
1

Hi,

  • We backup AWX using AWXBackup.
  • This results in a PVC and an AWXBackup.
  • All PVCs are backed up to another site. The AWXBackup resource is not, and will be lost if complete dataloss/disaster occurs.

Can I run a AWXRestore without the AWXBackup, and only the PVC?

Hope this makes sense! Please tell me if I further details are needed.

$ ka get awxbackup
NAME                         AGE
awx-backup-2023-10-19-1458   18h
$ ka get pvc

awx-backup.bash

manifest="

  backup_pvc_namespace: awx

kubectl apply -f - <<< $manifest

awx-restore.bash (this wouldn’t work[?] since the AWXBackup doesn’t exist)

manifest="
apiVersion: awx.ansible.com/v1beta1
kind: AWXRestore
metadata:
  name: restore-$1
  namespace: awx

kubectl apply -f - <<< $manifest

Hi,

You can achieve restoring without AWXBackup by specifying backup_pvc and backup_dir. See: https://github.com/ansible/awx-operator/tree/devel/roles/restore

As documented, the path for backup_dir can be gathered by:

$ kubectl get awxbackup awxbackup1 -o jsonpath="{.items[0].status.backupDirectory}"
/backups/tower-openshift-backup-2021-04-02-03:25:08

Or if you can dig into the PVC, there should be backup directory that named tower-openshift-backup-* and you can use this name for backup_dir as /backups/<backup directory>.

Cool, that’s easier than I thought it would be. Thanks again for helping out, very much appreciated.

For anyone else dropping by here, there’s another somewhat similar discussion on Github: Documentation: AWX backup secheduled job · Issue #1605 · ansible/awx-operator · GitHub

@kurokobo actually, I can’t seem to get this to work. I create an AWXRestore, but it never processes beyond this step:

EDIT: backupS not backup!

I mounted the PVC in a tmeporary pod, to verify the dir name.

ka exec persistent-volume -- ls /data

Any idea what I’m doing wrong here?

Hi, could you provide full logs of Operator?

Ah, is this root cause for you? Ignore my comment if it’s already solved.
