## Init Statemachine
### Inputs
1. `restic-password: ""`
2. `restic-password-to-rotate: ""`
### Manual init the restic repository for the first time
1. apply backup-and-restore pod:
`kubectl scale deployment backup-restore --replicas=1`
2. exec into pod and execute restore pod (press tab to get your exact pod name)
`kubectl exec -it backup-restore-... -- /usr/local/bin/init.sh`
3. remove backup-and-restore pod:
`kubectl scale deployment backup-restore --replicas=0`
### Password Rotation
1. apply backup-and-restore pod:
`kubectl scale deployment backup-restore --replicas=1`
2. add new password to restic repository
`restic key add ....`
=> Trigger ::
field (1) credential current
filed (2) credential new
3. replace field (1) with (2) & clear (2)
4. remove old key - ???
`restic remove ....`
```mermaid
stateDiagram-v2
[*] --> init
init --> backup_ready: trigger, restic-password !empty
backup_ready --> new_password_added: restic-password !empty && restic-password-to-rotate !empty
new_password_added --> backup_ready: restic-password !empty && restic-password-to-rotate empty
```
### First Steps
1. Cloud Testserver hochfahren
2. Dort backup-restore deployment (leeres Secret mgl.?), neues Secret "rotation-credential-secret" als Daten
3. mounten von angelegtem Secret in Pod backup-restore
4. ba*bash*ka Skript in pod starten -> liest Secret ?leer
5. Micha cons.
