-## Change Password
-
-1. Check restic-new-password env is set in backup deployment   
-   ```
-   kind: Deployment
-   metadata:
-     name: backup-restore

-       spec:
-         containers:

-     name: backup-secret
-   data:
-     restic-password: old
-     restic-new-password: new
-   ```
-3. Scale backup-restore deployment up:   
-   `kubectl -n forgejo scale deployment backup-restore --replicas=1`
-4. exec into pod and execute restore pod   
-   `kubectl -n forgejo exec -it backup-restore -- change-password.bb`
-5. Scale backup-restore deployment down:   
-  `kubectl -n forgejo scale deployment backup-restore --replicas=0`
-6. Replace restic-password with restic-new-password in secret   
-   ```
-   kind: Secret
-   metadata:
