Introduces a one-time configuration wizard (sudo ./setup.sh configure) that stores SITE_TZ, SITE_DOMAIN, and SITE_CADDY_NET in ~/docker/.config. Every service now uses these as prompt defaults so the user types common values once instead of re-answering the same questions for each service. - lib/common.sh: load_site_config / save_site_config; auto-loads on source; backward-compat BASE_DOMAIN alias kept for old .config files - setup.sh: run_site_configure wizard; first-run offer after base install; `sudo ./setup.sh configure` command to update defaults at any time - 14 services: TZ_VAL now honours SITE_TZ, falling back to /etc/timezone - 3 inline-heredoc services (filebrowser, homeassistant, ntfy): same fix - authelia: SITE_TZ/SITE_DOMAIN as prompt defaults; SITE_CADDY_NET replaces hardcoded caddy_net throughout (env, compose patch, network creation) - minecraft, frigate-audio: simplify BASE_DOMAIN read to use SITE_DOMAIN - sky-cam: SITE_TZ as default for timezone prompt https://claude.ai/code/session_01Y4dMKtkqkpvmgDKoRdzhTG

# Authelia — SSO + 2FA portal
|
||
|

Single login (with TOTP two-factor) that protects any Caddy subdomain via
|
||
forward-auth. Portal: **https://auth.${AUTHELIA_DOMAIN}**

|
||
$AUTHELIA_DIR/
|
||
├── docker-compose.yml
|
||

|

|

|
||
## Protect a service with Authelia
|
||
In that service's Caddy site block, add \`import authelia\`:
|
||
\`\`\`
|
||
myservice.${AUTHELIA_DOMAIN} {
|
||
import authelia
|
||
reverse_proxy localhost:PORT
|
||
}
|
||
\`\`\`
|
||
The \`(authelia)\` snippet and the \`auth.${AUTHELIA_DOMAIN}\` portal block were
|
||
added to \`$DOCKER_DIR/caddy/Caddyfile\` automatically.
|
||
|
||
## Manage
|
||
\`\`\`
|
||
cd $AUTHELIA_DIR
|
||
docker compose up -d # start
|
||
docker compose restart authelia
|
||
docker compose logs -f authelia
|
||
docker compose down # stop
|
||
\`\`\`
|
||
|
||
## Users
|
||
- Login with the **username** (not email). Admin user: \`${AUTHELIA_ADMIN_USER}\`.
|
||
- Tell users to click **Forgot Password** on first login to set their own
|
||
password (Authelia emails a reset link via SMTP).
|
||
- Add a user: copy a block in \`config/users.yml\`, change username/email/
|
||
displayname, generate a hash, then \`docker compose restart authelia\`:
|
||
\`\`\`
|
||
docker run --rm authelia/authelia:4.39.20 authelia crypto hash generate argon2 --password 'thepassword'
|
||
\`\`\`
|
||
|
||
## Notes
|
||
- Authelia listens on 9091 **internally only** (no published port) and is
|
||
reached through Caddy on the shared \`caddy_net\` docker network.
|
||
- Two-factor is **required** (\`default_policy: deny\`, rule \`two_factor\` for
|
||
\`*.${AUTHELIA_DOMAIN}\`).
