### Application Secrets

|
|
- Recommended scope: `hetznerterra` project, `prod` config only
|
|
|
|
#### `GRAFANA_ADMIN_PASSWORD`
|
|
- Transitional fallback only while migrating observability secrets to Doppler
|
|
- In steady state, store this in Doppler as `GRAFANA_ADMIN_PASSWORD`
|
|
|
|
## Setting Up Secrets
|
|
|
|
1. Go to your Gitea repository
|
|
2. Navigate to **Settings → Secrets → Actions**
|
|
3. Click **Add Secret**
|
|
4. Enter the secret name (exact match from above)
|
|
5. Paste the secret value
|
|
6. Click **Add Secret**
|
|
7. Repeat for all secrets
|
|
|
|
## Verification
|
|
|
|
After adding all secrets, trigger a workflow run:
|
|
```bash
|
|
git commit --allow-empty -m "ci: trigger workflow with new secrets"
|
|
git push
|
|
```
|
|
|
|
Check the workflow logs to verify all secrets are being used correctly.
|
|
|
|
## Security Notes
|
|
|
|
- Never commit secrets to the repository
|
|
- Use strong, unique passwords for Grafana and other services
|
|
- Prefer Doppler for runtime app/platform secrets after cluster bootstrap
|
|
- Rotate Tailscale auth keys periodically
|
|
- Review OAuth client permissions regularly
|
|
- The workflow automatically opens SSH/API access only for the runner's IP during deployment
