Only include the caddy_net network block in generated docker-compose.yml files when ~/docker/caddy exists. Prevents "network caddy_net declared as external, but could not be found" on standalone installs without Caddy. Affected: actualbudget, archivebox, arm, audiobookshelf, calibre-web, changedetection, drum-rhythm-game, emby, fmd, frigate, frigate-audio, frigate-notify, gatus, homeassistant, immich, iopaint, jellyfin, joplin, koha, lyrion, magicmirror, mail-archiver, mattermost, mealie, meshcentral, n8n, nextcloud, ntfy, onlyoffice, portainer, stirling-pdf, syncthing, traccar, unifi, uptimekuma, vaultwarden, wg-easy Skipped: authelia (creates caddy_net itself), caddy, crowdsec, wolf, wolf-pair, and services using network_mode: host with no caddy_net.

Workflow automation platform — connect all your self-hosted services with

a visual editor. Create webhooks, scheduled jobs, and multi-step automations.
|
|
|
|
## Access
|
|
- URL: http://localhost:5678
|
|
- On first run, n8n prompts you to create an owner account.
|
|
|
|
## Manage
|
|
```bash
|
|
docker compose up -d # start
|
|
docker compose down # stop
|
|
docker compose logs -f # logs
|
|
docker compose pull && docker compose down && docker compose up -d # update
|
|
```
|
|
|
|
## Environment
|
|
Edit `.env` to change `WEBHOOK_URL` or `N8N_HOST` after deployment,
|
|
then restart: `docker compose down && docker compose up -d`
