LET’S BUILD

Return to the preserved directory if needed

Run only after a failed recovery rehearsal, with the preserved before-restore directory present. This moves the failed restored tree aside without deleting it. If configuration/digest changes were involved, the old complete tree must include the matching old images and database; do not downgrade only Grafana’s image after a schema-changing upgrade.

Dedicated Linux host; Bash shell

sudo bash -eu <<'ROLLBACK'
[[ -d '/srv/academy-monitor.before-restore' && ! -e '/srv/academy-monitor.failed-restore' ]]
docker compose -f '/srv/academy-monitor/compose.yaml' down --timeout 60
mv '/srv/academy-monitor' '/srv/academy-monitor.failed-restore'
mv '/srv/academy-monitor.before-restore' '/srv/academy-monitor'
docker compose -f '/srv/academy-monitor/compose.yaml' up -d
ROLLBACK

How do I know it worked?

Preserved stack runs again; repeat readiness and history checks.

LET’S BUILD

Update deliberately and retire reversibly

Before changing a digest, review both vendors’ release/security/migration notes, rehearse the stopped backup and test the new version on separate approved infrastructure. Record OS package versions, both image digests, configuration and restore evidence together. There is no automatic latest/watchtower update here. For retirement, the next panel removes only this project’s containers/network and preserves bind data, configuration, secrets and backup for your approved retention/deletion process. It does not uninstall Docker or prune shared resources. Close the SSH tunnel normally. After secret compromise, rotate the actual Grafana account and revoke sessions/affected data-source credentials; replacing only the bootstrap file is insufficient.

Dedicated Linux host; Bash shell

sudo docker compose -f '/srv/academy-monitor/compose.yaml' down --timeout 60

How do I know it worked?

Project containers/network stopped; persistent files remain for an explicit retention decision.
