vector handed logflare its API key as ?api_key= in every sink URL, and
logflare 1.4.0 prints a failed request's whole URL in its Plug.Cowboy
error report. Its ingest fails on every request here, so the key was in
the analytics log about every ten seconds. The report is an error, so no
log level hides it.
Every sink now sends the key in the x-api-key header, which logflare
reads first. A start script refuses to start logflare while the vector
config it is given still puts the key in a URL.
The key is marked "applied", not "at-start": logflare writes it into its
default user once and never updates it, so the mesh must not rotate it
by restarting.
Next.js binds the address HOSTNAME names; docker sets HOSTNAME to the container's id, so studio
answered only on its network address while its image's health check asks localhost, and it read
unhealthy while working. HOSTNAME=:: as the upstream compose file sets it.
The manifest declared its secrets as secrets.secret.<name> and required a
"secret" provision, so the controller saw no own secrets and every accept
was refused (the influxdb defect of #180). The directories functions and
storage shared their ids with the containers of the same name, which the
host refuses as two resources with one identity. The containers are now
edge-functions and storage-api; the placed directories keep their ids and
paths.
ace runs Supabase under HAL as upstream's 13-container compose: a 2.2 GB
database (1.8 GB of it the dormant `novox` schema, 5.8 M rows in its largest
table), Kong at supabase.zurag.be, the pooler on 5433/6543. This is that stack
as a catalogue module, same images (the digests ace runs), same container
names so an assignment holds the running ones and a take replaces them.
The database stays inside the module. Supabase is a Postgres distribution: its
own image with pgsodium, pg_graphql, pg_net, vault and timescale preloaded, a
superuser (supabase_admin), a dozen reserved roles and a second database
(_supabase). A postgres-database grant - one database, one unprivileged role -
cannot hold it, so ace's data directory moves as a copy, not a dump/restore.
What HAL did by shell and environment the mesh now renders as files:
- kong.yml carries the anon/service keys and the dashboard login (owned by
kong's uid 100), instead of an entrypoint that eval'd the environment;
- GoTrue reads a dotenv file (auth -c), PostgREST a config file, Vector its yml
with the Logflare key in it, the database POSTGRES_PASSWORD_FILE and a
jwt.sql rendered with the secret (owned by postgres, uid 105). None of these
five containers has a secret in its environment.
- realtime, storage, meta, functions, analytics, studio and supavisor read
their credentials from the environment only; each declares
secrets-in-environment with the reason (ADR 0086).
- Upstreams are container names (supabase-db, supabase-kong, ...) instead of
compose service names, which the mesh does not have.
- SITE_URL / API_EXTERNAL_URL / SUPABASE_PUBLIC_URL are
https://${bound:route:name} (mesh-controller #149); on ace HAL rendered them
as "https://supabase." - broken today.
- Vector reads the docker socket, as upstream does, but now includes only this
module's containers instead of every container's logs on the machine.
Three things compose did that a declaration cannot, done as steps: a run-once
seed copies the image's /etc/postgresql-custom into the placed config
directory with cp -n (a named volume did that implicitly; never overwrites the
pgsodium root key), and two run-once gates wait for the database and for
Logflare, which compose expressed as depends_on: service_healthy.
The pooler bootstrap (pooler.exs) takes the tenant id and pool sizes from
settings.json, the module's one merge:json file, so ace keeps its tenant
"zurag"; and it repoints an existing tenant whose database host is not
supabase-db - HAL created ace's with host "db", which no longer resolves.
Secrets (vault, requires "secret"): postgres, jwt, anon-key,
service-role-key, dashboard-user, dashboard, logflare, pooler-vault,
key-base-a + key-base-b (concatenated: Phoenix wants 64+ bytes, a minted
secret is 40), openai. Three cannot be minted on any machine: anon-key and
service-role-key are JWTs signed with jwt, and pooler-vault must be exactly
32 bytes (AES-256-GCM, found in the bed). They are accepted. On ace every
secret the data already knows is accepted (all but key-base-a/b).
Not carried: Kong's 8443 and Logflare's 4000 on all interfaces (nothing
outside the module uses them); realtime's DB_ENC_KEY stays upstream's constant
(realtime deletes and re-seeds that tenant from its environment every start,
and the key must be exactly 16 bytes).
Verified: catalogue tests with MESH_CATALOGUE pointed here on mesh-controller
main and #149 (on main the render is refused for "name", never written
empty). The #149 resolution with stub providers, turned into a throwaway
stack of all 13 pinned digests with dummy secrets and the rendered files at
their owners and modes: the database initialised through the rendered scripts
(jwt setting applied, _analytics/_supavisor created, roles' password from
POSTGRES_PASSWORD_FILE); through Kong: REST 200 with the anon key and 401
without, auth health and settings 200, storage buckets 200, GraphQL 200, pg-meta
200, an edge function 200, Studio 401 without and 200 with the dashboard login,
realtime tenant health 200; the pooler in session and transaction mode as
postgres.zurag; a tenant set to host "db" was repointed to supabase-db by the
bootstrap and connections worked.
