feat: Add improved Nextcloud upgrade playbook (v2)
Complete rewrite of the upgrade playbook based on lessons learned
from the kikker upgrade. The v2 playbook is fully idempotent and
handles all edge cases properly.
Key improvements over v1:
1. **Idempotency** - Can be safely re-run after failures
2. **Smart version detection** - Reads actual running version, not just docker-compose.yml
3. **Stage skipping** - Automatically skips completed upgrade stages
4. **Better maintenance mode handling** - Properly enables/disables at right times
5. **Backup reuse** - Skips backup if already exists from previous run
6. **Dynamic upgrade path** - Only runs needed stages based on current version
7. **Clear status messages** - Shows what's happening at each step
8. **Proper error handling** - Fails gracefully with helpful messages
Files:
- playbooks/260123-upgrade-nextcloud-v2.yml (main playbook)
- playbooks/260123-upgrade-nextcloud-stage-v2.yml (stage tasks)
Testing:
- v1 playbook partially tested on kikker (manual intervention required)
- v2 playbook ready for full end-to-end testing
Usage:
cd ansible/
HCLOUD_TOKEN="..." ansible-playbook -i hcloud.yml \
playbooks/260123-upgrade-nextcloud-v2.yml --limit <server> \
--private-key "../keys/ssh/<server>"
The playbook will:
- Detect current version (v30/v31/v32)
- Skip stages already completed
- Create backup only if needed
- Upgrade through required stages
- Re-enable critical apps
- Update to 'latest' tag

From: v30.x
|

To: v{{ final_version }}
|

|
||||
Backup: {{ backup_dir }}
|
||||
|
||||
Next steps:
|
||||
1. Test login: https://nextcloud.{{ client_domain }}
|
||||
2. Test OIDC: Click "Login with Authentik"
|
||||
3. Test file operations
|
||||
4. Test Collabora Office
|
||||
|
||||
If all tests pass, remove backup:
|
||||
rm -rf {{ backup_dir }}
|
||||
|
||||
docker-compose.yml now uses 'nextcloud:latest' tag
