Claude bec9228c55 Back up existing files before every service overwrites them
Confirmed live: install_frigate()'s fresh-install path overwrote a
working, hand-crafted docker-compose.yml (Frigate + mosquitto +
frigate-notify) with zero backup, because that file's shape didn't match
what frigate.sh's own "existing install" detection knew how to recognize.
Every service's own detection is a judgment call about what counts as
"already installed" and can miss a real setup built outside this repo's
conventions.

lib/common.sh gains backup_if_exists(FILE) — copies FILE to
FILE.bak.<timestamp> if it exists, no-ops otherwise (including DRY_RUN).
Applied before every service's own `cat > docker-compose.yml`/`cat > .env`
write across all 60 services that do one (115 call sites), plus a matching
standalone-mode stub added to every service's own bootstrap block, same
convention already used for port_in_use/find_free_port. This doesn't
replace a service's own update/fresh-reinstall detection — it's the safety
net underneath it, so a wrong detection costs a .bak file to restore from
instead of the original silently disappearing.

Also fixes the actual gap that surfaced this: services/frigate.sh's
Authelia offer only checked for Authelia installed locally on Frigate's
own box, which is never true for a dedicated NVR box with no local Caddy
either (the common shape — Caddy lives elsewhere, snippet-generation mode
already handles that). Now offers Authelia protection unconditionally and,
when Authelia isn't local, asks whether it lives on the same machine as
Caddy (still "import authelia", since that's local to wherever Caddy ends
up) or on a genuinely separate third machine (the explicit
header-pinned forward_auth form, per CLAUDE.md's "forward_auth to a remote
Authelia" note, needed because a bare authelia:9091 shortcut only works
one hop).

Claude 7a1f09a0f7 Rename reinstall-mode prompt; make security-dashboard's "Full reinstall" a real teardown
Two-part change discussed and scoped in this session before touching
anything:

1. Rename "Reinstall in place" (r) -> "Update" (u) and "Full install" (f)
   -> "Full reinstall" everywhere the prompt appears: lib/common.sh's
   shared prompt_reinstall_mode(), plus the three services that carry
   their own duplicated standalone-stub copy of it for standalone
   execution (asterisk.sh, coturn.sh, wordpress.sh — per this repo's
   documented standalone-bootstrap pattern). Internal state values
   (update/fresh/cancel) are unchanged, so no other service's case
   statement needed touching. docs/anveo-direct-setup-guide.md's `r`
   reference updated to `u` to match. attic/asterisk-digital-ocean.sh
   deliberately left alone — this repo's own policy is to not backport
   fixes into attic/.

2. security-dashboard.sh's "Full reinstall" now does a real teardown
   before reinstalling — stops and removes the systemd unit, sudoers
   grant, Caddy site block, and secdash system user, then proceeds
   through the normal fresh-install flow — instead of just overwriting
   files in place while leaving the old service running underneath.
   Prototype for a pattern discussed for other services later: split the
   destructive question out explicitly ("also delete
   dashboard-admins.conf — per-admin extension scoping?", default n) so
   full reinstall doesn't silently discard state a plain "start over"
   request wouldn't expect to lose. Verified the backup/restore mechanics
   (mktemp, copy out before teardown, copy back after) against a mock
   under `set -u` for both the preserve and wipe paths before shipping.

Update mode was already the strongest existing example of surfacing
newer optional prompts (its "Reconfigure Caddy protection?" /
"Reconfigure per-admin scoping?" sub-prompts already cover every setting
fresh-install offers) — no changes needed there for this service.

Claude abd1bcd35d Fix wordpress.sh picking an already-occupied port
Reported live: a fresh site's container failed to start with "address
already in use" on its assigned port. wordpress.sh scanned for a free
port by grepping `docker ps -a`'s port list — that only reflects ports
Docker itself currently has bound, so it's blind to ports held by
non-Docker processes or anything Docker isn't reporting cleanly at that
instant. Every other service in this repo scans with find_free_port
(checks actual OS-level listening sockets via ss) per CLAUDE.md's "Port
collision avoidance" section; wordpress.sh was the one holdout still using
its own weaker check. Switched to the shared helper, already available in
this file's own standalone stub and via lib/common.sh — no new dependency,
just using what was already sitting there unused.

Claude 9e06ed4b83 Bake cross-service port collision avoidance into every service script
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.

Claude a5d57050b3 wordpress: switch to dedicated MariaDB per site (was shared)
Reconsidered after the shared-MariaDB design's real cost became clear:
Kopia's generic backup (services/backup.sh) stops a service's
container to snapshot it, so a shared MariaDB instance would back up
-- and would have to be restored -- as one unit covering every site at
once. Restoring just one site's database to an earlier point meant
restoring the whole shared snapshot to a temporary location first and
manually extracting that site's data back out, not a direct restore.

Each site now gets its own dedicated MariaDB container embedded in its
own docker-compose.yml (same pattern as services/nextcloud.sh) instead
of registering a database on a shared instance:
- Removed _wordpress_ensure_shared_db() and the wordpress-db/
  wordpress_net shared resources entirely.
- Each site's compose file gets a `db` service (container
  <site>-db) on an explicitly-named per-site default network
  (<site>_net), so wp-cli's one-off container reliably joins the
  right network without depending on Docker Compose's implicit
  naming convention.
- DB creation goes through the mariadb image's own MYSQL_DATABASE/
  MYSQL_USER/MYSQL_PASSWORD env vars on first boot (same as
  nextcloud.sh) instead of an imperative `docker exec mysql -e
  "CREATE DATABASE..."` against a shared container.
- Root and site DB passwords are both reused across reruns (read from
  the existing .env), verified via a real update-mode rerun.

Tradeoff, stated in both the script's header comment and the generated
per-site README: more RAM per site (~100-150MB for a full MariaDB
container instead of a slice of one shared instance) in exchange for
independent backup/restore. Data was already fully isolated either way
(separate database + user, always required since WordPress's schema
uses generic table names) -- the shared-vs-dedicated choice was only
ever about the container/process, not the data.

Re-verified end-to-end against the fake docker shim: distinct ports,
distinct dedicated DB containers/networks per site, correct compose/
.env structure, credentials preserved across an update-mode rerun.

docs/vps-sizing-recommendations.md: updated to match -- WordPress
capacity recomputed for dedicated-per-site MariaDB (~580MB headroom at
4 sites, ~976MB at 2, vs. the shared design's ~700MB/~950MB).

Claude a26d1831ee Add services/wordpress.sh — multi-site WordPress with shared MariaDB
New service: self-hosted WordPress, sized for running several
independent sites the way a hosting company would, not just one blog.

- Multi-site from the start: every site requires a name (no unnamed
  "first instance" special case like mattermost's — there's no
  backward-compat reason to special-case one here) and gets its own
  directory/container/port, but all sites share ONE MariaDB container
  (chain-installed on first site, reused by every other one) instead of
  a dedicated database container per site — same resource-sharing idea
  as services/coturn.sh, just scoped to WordPress's own sites rather
  than shared across different services. Each site gets its own
  database + user within that shared instance.
- E-commerce is just WooCommerce, a normal WordPress plugin — no
  separate infrastructure. PHP memory_limit/upload_max_filesize/
  post_max_size are pre-tuned (256M/64M/64M) so a product-catalog
  import doesn't hit default-image limits on the first try.
- wp-cli (official wordpress:cli image, run as a one-off container
  sharing the site's html volume) does the initial WordPress core
  install non-interactively — title, admin account — so there's no
  browser setup wizard to remember per site. Falls back to printing
  the exact manual command if the site wasn't ready in time.
- Auto-scans for a free host port per site (multiple sites can't all
  bind 8090), matching the "auto-scanned free ports for extras" idea
  already used by mattermost's multi-instance support.
- DB and admin passwords are reused across reruns (checked against the
  DB-password-regeneration bug class already fixed elsewhere in this
  repo, e.g. PR #265) — verified via a real update-mode rerun that the
  credential doesn't change.
- setup.sh: is_installed() gets a wordpress case — every site is named
  from the first one on, so there's never a plain $DOCKER_DIR/wordpress
  directory the default case could match against.
- README.md: added to the utilities services table + copiable list per
  CLAUDE.md's three-step rule for new services. Also fixed `coturn`
  being in the homelab row's prose but missing from the copiable list
  block below it — a pre-existing gap from when coturn.sh was merged.

Verified end-to-end via non-interactive dry runs against a fake docker
shim (no live daemon in this environment): 3 sites installed in
sequence get 3 distinct databases, 3 distinct auto-scanned ports, the
shared DB is only set up once, and an update-mode rerun preserves the
existing DB password rather than regenerating it.
