With 70+ services sharing a handful of common default ports (emby and
jellyfin both default to 8096, changedetection and frigate both default
to 5000, arm and nextcloud both default to 8080...), nothing previously
checked whether a service's default port was actually free on the host.
Whichever service installed second would silently write a compose file
claiming an already-held port, only failing at `docker compose up` time.
Adds two shared helpers to lib/common.sh:
- port_in_use PORT [PROTO] — true if something's already listening
- find_free_port VARNAME START [PROTO] — scans upward, writes back the
first free port
Every service that publishes a fixed host port now scans before writing
docker-compose.yml, on every install (not just when adding an explicit
additional instance). On a normal single-install host this is a silent
no-op; it only changes behavior when something else already holds the
port.
- The 19 services already given multi-instance support this session had
their port scan moved out of the "add instance" branch to run
unconditionally, since the same collision risk exists on a plain first
install.
- 20 more services with previously-hardcoded ports gained scanning for
the first time: archivebox, arm, calibre-web, changedetection,
drum-rhythm-game, gatus, n8n, nextcloud, onlyoffice, stirling-pdf,
uptimekuma, portainer, iopaint (both GPU/CPU compose branches), koha
(paired), syncthing (paired), wg-easy (paired, plus WG_PORT env so
generated peer configs keep the right Endpoint), homeassistant
(bridge-mode only — host mode can only warn), frigate and
frigate-audio (multi-port stacks, moved together).
- caddy.sh is the deliberate exception: 80/443 stay fixed and only warn
on collision, since silently moving Caddy itself would leave nothing
listening where any client actually looks.
- authelia.sh needs no change — it has no published host port at all.
- Every service's standalone bootstrap fallback (sudo bash services/x.sh
with no sibling files) got the same two helpers duplicated into its
stub block, matching how every other shared helper is already handled
there.
Documents the full pattern in CLAUDE.md's new "Port collision avoidance"
section, including the quoted-heredoc/backtick-escaping gotcha and the
network_mode:host limitation (can only scan ports the app takes as a
configurable env var).
Verified via bash -n on every changed file, plus functional runs seeding
occupied ports for each collision shape used here (single, paired,
multi-port stacks) and confirming the scan/shift and generated
compose/README output are correct — including the emby/jellyfin,
nextcloud/arm, and frigate/changedetection collision scenarios that
originally motivated this.
services/asterisk-digital-ocean.sh was a near-verbatim copy of
services/asterisk.sh — same vendor refresh, compose template, messaging
dialplan, presence alerts, UFW rules and dashboard/trunk chaining, with the
helper functions renamed _asterisk_do_*. Two copies meant every fix had to
land twice, and several never did.
There is now one `asterisk` service. It reads the DigitalOcean metadata
service and asks either way (so a droplet with metadata blocked, or another
provider's public VM, can still opt in), then gates the genuinely
droplet-specific behaviour on that one answer: swapfile for low-RAM plans,
public-FQDN-only setup with no LAN/VLAN prompts, a Caddy site block pinned
to that FQDN, the remote-Authelia option, and the doctl Cloud Firewall.
Two things that were droplet-only for no real reason now apply everywhere:
the entrypoint patch that writes security-level events to logs/full, and
the logrotate config for that file. Without them the Security Dashboard's
Security Log tab and CrowdSec's Asterisk acquisition were silently empty on
every home/LAN install; crowdsec.sh now detects either install directory.
Existing droplets are left alone: an install at ~/docker/asterisk-digital-ocean
keeps its directory and easy-asterisk-do container names, since its Caddyfile
block, UFW rules, Cloud Firewall, CrowdSec acquisition and PSTN trunk all
name those exactly. New installs use ~/docker/asterisk / easy-asterisk.
`sudo ./setup.sh asterisk-digital-ocean` still works via a new SERVICE_ALIAS
map in setup.sh, without a second menu entry.

New "Add another protected domain to this instance" option on re-run,
via add_authelia_domain(): appends a session.cookies entry and an
access_control.rules entry (both YAML lists Authelia natively supports)
plus a Caddy auth.<domain> portal block for the new domain, all on the
same Authelia + Redis container instead of standing up a second full
stack. Each domain gets its own login/session, sharing one user
database — the right fit when a single (possibly upsized) droplet ends
up fronting more than one domain, without doubling the RAM cost of a
second Authelia+Redis instance. Documents both this and the
already-working separate-instance path in CLAUDE.md, with the
per-approach tradeoffs.
The generated auth.<domain> block's bare "reverse_proxy authelia:9091"
let Caddy recompute X-Forwarded-Host from its own incoming request
(always auth.<domain> itself) on every hop through it, overwriting
whatever a forward_auth caller elsewhere had already set for its own
domain. Confirmed live: a remote site's forward_auth check always
evaluated as if it were for the Authelia portal itself (bypass policy),
so 2FA silently never triggered for any domain going through it.
43 services declare caddy_net as "external: true" in their compose
file, meaning they require it to already exist — but only Caddy's own
compose file actually creates it (authelia.sh was the sole exception,
with its own inline check-and-create). Installing any of the other 42
before Caddy fails outright with "network caddy_net declared as
external, but could not be found."
Adds ensure_caddy_network to lib/common.sh, called from require_docker
(which every install_* function already calls first), so the network
exists regardless of install order without touching each service file.
Removes authelia.sh's now-redundant duplicate of the same check.
Also documents in CLAUDE.md that network_mode: host services (asterisk/
asterisk-do) need host.docker.internal, not localhost, when Caddy
reverse-proxies to them — the fix from the previous commit.
New site config key: CADDY_REMOTE_HOST (set via 'sudo ./setup.sh configure').
When set, configure_caddy_for_service operates in "remote" mode instead of
writing to a local Caddyfile:
- Upstream uses CADDY_REMOTE_HOST:PORT (host IP, not container name)
- Snippet saved to ~/docker/caddy-snippets/<subdomain>.caddy
- User is shown scp/rsync commands to copy it to the Caddy machine
Three modes in configure_caddy_for_service (lib/common.sh and inline stubs):
local: ~/docker/caddy/ exists → write Caddyfile + reload (existing behavior)
remote: CADDY_REMOTE_HOST set → save snippet, print copy instructions
none: neither configured → silent return (unchanged)
All 31 service standalone bootstrap stubs updated with the new logic.
CADDY_REMOTE_HOST global added to all 42 standalone bootstrap sections.
setup.sh configure now prompts for CADDY_REMOTE_HOST with a clear explanation.
wolf.sh: add missing stubs (configure_caddy_for_service, write_readme,
prompt_yn, ensure_docker_dir_ownership) and the Authelia/Caddy/start calls
that were missing from the install function.

Each service can now be run directly with sudo bash <service>.sh on any
machine with Docker installed, without needing the full post-install repo.
Uses the shared bootstrap pattern from docs/standalone-template.sh.
https://claude.ai/code/session_014CCYqVwW6d6f5dw1qRokYt
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
- lib/common.sh: add write_readme helper. Every module now writes a README.md
into its ~/docker/<service>/ folder (self-documenting service folders).
- services/authelia.sh: SSO + 2FA portal, ported from the authelia-setup repo +
the monolith's working block (secrets + Argon2 hash generation, caddy_net,
Caddyfile forward-auth snippet + portal block, README). Guards against
clobbering an existing install.
- services/{filebrowser,ntfy,uptimekuma,portainer,watchtower}.sh: mechanical
migrations from the monolith, each with a README. Ports 8085/8090/3001/9443/—.
All pass bash -n; ./setup.sh --list shows them under homelab; dry-run run-one
exits 0 for each with real commands guarded.
