Both apps were barred from multiple instances by the same rule: a
service or container name with no <app> prefix cannot be made unique per
instance, so a second copy would fight the first for it.
Prometheus is now fully unblocked. node-exporter and cadvisor became
prometheus-node-exporter and prometheus-cadvisor — service key,
container_name and SERVICE_TAG default together — and prometheus.yml's
scrape targets follow them. The image references (prom/node-exporter,
gcr.io/cadvisor/cadvisor) and the job_name labels are deliberately
untouched: the first are upstream coordinates, the second are labels
dashboards and alert rules key off, and renaming either would break
something to fix nothing.
Stoat's sixteen services are now all stoat-prefixed. Its container_names
already were, so only the service keys and their depends_on references
moved. The subtlety is DNS: compose registers the service name as a
network alias, so renaming a key silently retires the name anything
else resolves it by — Revolt.toml reaches the broker as "rabbit", the
Caddyfile proxies to api, events, autumn, january and gifbox, and the
bucket job talks to http://minio:9000. Ten services already carried an
explicit alias that survives the rename; the six that did not
(database, redis, rabbit, createbuckets, crond, pushd) have been given
one holding their old short name. Every name that resolved before still
resolves. Verified by parsing the result: 16 services, every one keeping
its short alias, and no dangling depends_on in either app.
Stoat stays non-instanceable, but for one narrower reason now, recorded
in its config: LiveKit advertises its own tcp_port 7881 and UDP range
50000-50100 to clients from livekit.yml, so those cannot be randomised
per instance without generating that file per instance and allocating a
range for each.
Stoat's port descriptors name their parent service, so they follow the
rename too: caddy -> stoat-caddy, livekit -> stoat-livekit.

Installing rocketchat failed with
invalid IPv4 address: ParseAddr("IP_DATA_2"): unable to parse IP
ipUpdateComposeTags allocates one IP per SERVICE_TAG_N annotation and fills
IP_TAG_i only where SERVICE_TAG_i exists. The four new apps tagged only their
primary service, so every sidecar — matrix's postgres, mattermost's postgres,
rocketchat's mongo, and fifteen of stoat's sixteen — kept a literal IP_DATA_n
in the deployed compose and docker refused to create the container.
Tag every service that carries an ipv4_address, index-aligned with its IP_TAG.
For stoat that also meant moving caddy from SERVICE_TAG_1 to _6 so the indices
line up with the IPs rather than the reading order.
mastodon had the same latent break (IP_TAG_2 and _3 untagged) and is fixed the
same way — it would have failed on first install for the same reason.
SERVICE_TAG carries the compose *key*, not container_name: 'libreportal app
restart <app> <service>' passes it to 'docker compose restart', which only
understands keys.

VAPID: the two values are the halves of one P-256 keypair, not independent
secrets — the browser verifies that a push is signed by the private key matching
the public key it subscribed with. The RANDOMIZED* generators mint each
placeholder on its own, so they produced two unrelated strings and web push could
never have worked. Generate the pair in mastodon_install_post_setup the way stoat
already does, encoded as Mastodon's webpush gem expects: unpadded URL-safe base64
of the 32-byte private scalar and the 65-byte uncompressed public point, sliced
out of the SEC1 DER. Verified by rebuilding the key from the emitted private half
and re-deriving the public point — openssl accepts it and the point matches.
Generated once and never rotated (rotation would invalidate every subscription),
but a pair of the wrong shape is replaced, so an install carrying the old
unrelated strings heals itself on next install — their public half is 42 chars
where a real point is 87.
Slots: CFG_<APP>_DB_PASSWORD -> CFG_<APP>_DB_PASSWORD_1 and likewise for
DB_ROOT_PASSWORD, across mastodon, owncloud, mattermost, matrix, nextcloud and
bookstack, so a database credential is always a numbered slot and a second one is
just _2. Renaming a key means reconciliation drops the old and adds the new
holding its placeholder, so an existing install regenerates unless the value is
carried over first — documented, including that the old file survives as
.<app>.config.bak.

Five apps (mastodon, owncloud, mattermost, matrix, stoat) took their generated
secrets from the compose-side generator tags PASSWORD_TAG_<n>/RANDOM_TAG_<n>/
HEX_TAG_<n>/VAPID_TAG_<n>. Those mint a fresh secret on every templating run, so
a reinstall handed the app a new database password while its data volume kept the
one initdb was given, and the app came back up unable to open its own database.
Move them to <app>.config as RANDOMIZED* placeholders, reaching the compose via
the #LIBREPORTAL|<APP>_<KEY>_TAG| mechanism tags_processor_app_config_values
already provides. No new handler: the tag name is derived from the config key, so
this is a config line plus a tag per secret. Generation is unchanged — still
random on first install; the value is now remembered instead of re-rolled.
Also fixes two things this exposed:
- The RANDOMIZED* replacers matched unanchored. `sort -u` orders slots lexically
(1, 10, 11, 2), so slot 1's pattern rewrote the prefix inside slot 10's
placeholder and slots 10+ ended up holding slot 1's secret with a digit glued
on — derivable, and invisible because the values weren't byte-identical.
Anchoring with \b makes match order irrelevant. Verified at 20 slots across
all four placeholder types: 64 keys, 64 distinct values, no prefix collisions.
- generateRandomPassword drew from base64 without constraining the mix; measured
over 2000 draws, 1 in 40 contained no digit at all. Retry until the result has
both a digit and a letter, bounded so a pathological length can't spin.
owncloud gains a fix in passing: its compose seeded the admin account from
PASSWORD_TAG_2 while the WebUI displayed CFG_OWNCLOUD_ADMIN_PASSWORD, which was
generated separately and never used. Both now read the same value.

Sixteen containers: MongoDB, Valkey, RabbitMQ, MinIO and eleven Stoat services.
Servers, channels, roles and voice/video through LiveKit — the nearest thing in
the catalogue to Discord itself, at the price of being much the heaviest app in
it. Does not federate.
The compose service keys are deliberately kept identical to upstream's
(database, redis, api, autumn, ...) while container_name is prefixed stoat-.
Compose registers both on the network, so upstream's internal defaults keep
resolving and LibrePortal still gets the prefixed names its port, firewall and
backup layers key on.
Upstream's Caddy is kept as the internal path router and Traefik simply proxies
to it, which is upstream's own supported behind-a-reverse-proxy mode —
reimplementing eight path routes as Traefik labels would be a second copy to
keep in sync for nothing. The install hook is a non-interactive port of
generate_config.sh, and it never rewrites an existing secrets.env:
REVOLT__FILES__ENCRYPTION_KEY decrypts every file ever uploaded, so
regenerating it would orphan the whole media store.
LiveKit's UDP media range is published literally rather than through the port
table, because the firewall rebuild emits /tcp rules only and a range declared
there would produce a wrong rule rather than no rule. Voice falls back to TCP
7881 until the range is opened by hand; the post-install notice says so.
