Extract coturn into a shared service; add Mattermost multi-instance support
Asterisk and Mattermost each used to embed their own dedicated coturn container (network_mode: host), and their default relay port ranges overlapped by ~100 UDP ports — running both on one box meant a coin-flip over which service's active call lost its media relay. - services/coturn.sh: new shared TURN/STUN relay, one instance for every consumer instead of one each. Runs --lt-cred-mech with a SQLite user database (not --use-auth-secret — coturn doesn't support both auth mechanisms on one instance at once, confirmed via coturn's own upstream docs/issues) so each consumer gets its own dedicated username/password without stepping on any other's. - lib/common.sh: ensure_coturn_user() — chain-installs coturn.sh on first need (same declare -F guard pattern as the existing asterisk -> security-dashboard chaining) and registers/reuses a per-consumer credential, mirroring configure_caddy_for_service's out-param convention. - services/asterisk.sh: _asterisk_write_compose gains a USE_EMBEDDED_COTURN flag. New installs use the shared service; existing installs keep their dedicated coturn exactly as-is on every "update" (detected from the existing compose file before regenerating it, so a rebuild can never silently drop the container its own .env TURN_PASSWORD still points at) and only switch on an explicit "fresh" reinstall, with a warning first. - services/mattermost.sh: same embedded/shared coturn handling, plus genuine multi-instance support (separate dir/containers/DB/ports per instance, auto-scanned free ports for extras) for real isolation between groups, as opposed to Team Edition's built-in Teams feature. Calls plugin TURN config switched from the HMAC "TURN Static Auth Secret" field to the verified "ICE Servers Configurations" JSON field, which accepts the same fixed username/credential shared coturn issues. Also fixes a latent bug found while adding proper update-mode detection: DB_PASS/MM_SECRET were regenerated on every single rerun with no existing-install check at all, silently breaking Postgres auth on any reinstall. - CLAUDE.md: documents the ensure_coturn_user pattern (including the auth-mechanism constraint and the embedded-coturn migration-safety rule) for any future service that needs TURN.

# coturn — shared TURN/STUN relay
|
||||
|
||||
One coturn instance shared by every service on this box that needs TURN
|
||||
(Asterisk, Mattermost Calls, anything added later) — instead of each running
|
||||
its own and fighting over host ports for the relay range.
|
||||
|
||||
Runs in long-term-credential mode with a SQLite user database. Each
|
||||
consumer gets its own dedicated username/password, registered automatically
|
||||
by that service's installer via \`ensure_coturn_user()\` — you don't
|
||||
normally need to touch this directly.
|
||||
|
||||
## Identity
|
||||
- Realm: \`$COTURN_REALM\`
|
||||
- Host clients connect to: \`$COTURN_HOST\`
|
||||
- Listening port: \`$COTURN_PORT\`
|
||||
- Relay port range: \`$COTURN_MIN_PORT-$COTURN_MAX_PORT\` (udp)
|
||||
|
||||
**Changing any of the above breaks TURN for every already-registered
|
||||
consumer until that service's installer is re-run** — they cache the host/
|
||||
port/credentials in their own \`.env\` at registration time, not read live.
|
||||
|
||||
## Manage users
|
||||
\`\`\`bash
|
||||
sudo ./coturn_user.sh list
|
||||
sudo ./coturn_user.sh add <name> <password>
|
||||
sudo ./coturn_user.sh remove <name>
|
||||
\`\`\`
|
||||
Per-consumer credentials are also cached in \`users/<name>.env\` (chmod 600)
|
||||
so a service re-running its own installer reuses the same credential
|
||||
instead of silently minting a new one and orphaning the old.
|
||||
|
||||
## Manage the container
|
||||
\`\`\`bash
|
||||
docker compose up -d
|
||||
docker compose down
|
||||
docker compose logs -f
|
||||
docker compose pull && docker compose up -d
|
||||
\`\`\`
|
||||
|
||||
## Adding a new service that needs TURN
|
||||
In that service's \`install_<name>()\`, after \`require_docker\`:
|
||||
\`\`\`bash
|
||||
ensure_coturn_user "my-service"
|
||||
if [ -n "\$COTURN_HOST" ]; then
|
||||
