traccar.sh's caddy_net wiring was fixed to mirror configure_caddy_for_service's
own mode resolution (CADDY_MODE from site config, then a local ~/docker/caddy,
then the legacy CADDY_REMOTE_HOST var) instead of only checking for the local
directory. That same bare directory check was copy-pasted into the caddy_net
wiring of every other Docker service in the repo, so a site with Caddy on a
different box would silently fail to join any of their containers to caddy_net
during setup (or, for homeassistant/koha, only get half the wiring right).
Applied the same fix mechanically across all 37 services using the standard
_CADDY_NET_BLOCK/_CADDY_NET_SECTION pattern (verified identical text via
scripted diff before touching any of them), plus by hand for:
- homeassistant.sh and koha.sh, which use their own differently-shaped
variables (HA_CADDY_NET_LINES / _CADDY_NET_ENTRY) for the same decision
- paintplus.sh and ai-stack.sh, which do a live `docker network connect`
instead of a compose network block
- watchyourlan.sh, whose Caddy note was worded for local-only setups
sms-inbound.sh got more than a mode swap: its Caddy wiring was hand-rolled
(not routed through configure_caddy_for_service) and had no remote-Caddy
path at all — a remote Caddy box would get a misleading "Caddy isn't
installed here" message instead of a snippet. Added
_sms_write_caddy_snippet(), mirroring the snippet-file pattern
configure_caddy_for_service uses everywhere else, and pointed the firewall
gate at the same three-way mode instead of a two-way dir check.
Verified: bash -n across all of services/*.sh, a scripted check that every
touched file has exactly one _CADDY_MODE resolution and no leftover bare
`[ -d "$DOCKER_DIR/caddy" ]` feeding a caddy_net decision, and spot-checked
docker compose config renders (traccar, mattermost) confirming the ${VAR}
interpolation and multi-service usage sites still resolve correctly.

|
Self-hosted cloud storage with SMB/local file access.
|
|
|
|
## Access
|
|
|
|
- URL: https://cloud.${SITE_DOMAIN:-example.com} (or http://localhost:8080)
|
|
- Admin: admin
|
|
- Password: see \`NEXTCLOUD_ADMIN_PASSWORD\` in \`$DIR/.env\`
|
|
|
|
## Manage
|
|
|
|
\`\`\`bash
|
|
docker compose up -d --build # start / rebuild
|
|
docker compose down # stop
|
|
docker compose logs -f # follow logs
|
|
docker compose pull && docker compose up -d --build # update
|
|
\`\`\`
|
|
|
|
## Run occ commands
|
|
|
|
\`\`\`bash
|
|
docker exec -u www-data nextcloud php occ <command>
|
|
\`\`\`
|
|
|
|
## Enable external storage (SMB / local)
|
|
|
|
\`\`\`bash
|
|
docker exec -u www-data nextcloud php occ app:enable files_external
|
|
\`\`\`
|
|
|
|
Then configure mounts in Nextcloud → Settings → External Storages.
|
|
|
|
## Backup
|
|
|
|
Back up these directories:
|
|
- \`$DIR/html\` — Nextcloud application files
|
|
- \`$DIR/config\` — configuration
|
|
- \`$DIR/custom_apps\` — third-party apps
|
