Resolve the security review of #389 (findings 1-4):
- .dockerignore: every env/credential pattern is now **/-prefixed
(**/.env, **/.env.*, **/node_modules, **/.npmrc, ..., **/secrets,
**/*.pem, **/*.key, ...) and the redundant 'secrets/' line is dropped.
Docker's matcher (moby/patternmatcher) anchors slash-less patterns to
the context root, so the bare forms excluded nothing under apps/server/;
**/ matches the root AND any nested depth. (finding 1, 3)
- tests/secrets-not-embedded.test.mjs: the dockerignore matcher is now a
faithful port of moby/patternmatcher (filepath.Clean + anchored full-path
match + parent-directory propagation), not gitignore basename semantics;
asserts nested example paths (apps/server/.npmrc, config/server.key,
apps/server/secrets/...) are excluded; requires no redundant equivalent
patterns verbatim; adds mutation probes for bare-pattern and
duplicate-pattern regressions. (finding 2, 3)
- apps/server/Dockerfile + compose.yaml: guarantee restated precisely
(credential files excluded at the context root AND at any depth).
- .gitea/workflows/ci.yml: new job runs
'node --test tests/secrets-not-embedded.test.mjs' on every PR; the
docker-gated layer-scan probe runs where a daemon exists, skips cleanly
otherwise. (finding 4)
- tests/compose-config.test.mjs: .dockerignore presence list updated to the
**/-prefixed forms (node_modules, .env).
Tested: secrets suite 16 tests -> 15 pass / 1 docker-gated skip / 0 fail;
full suite 101 pass / 12 fail / 8 skip, failures identical to clean main
(env-dependent pnpm/Node-24 suites); matcher port verified against the
moby/patternmatcher evidence table.
- .dockerignore: exclude env + credential files (.npmrc, .netrc, .aws, .ssh,
secrets/, *.pem, *.key, *.p12, *.pfx, *.jks, id_rsa, id_ed25519, ...) from
the build context so a local secret file cannot be embedded in the image
- Dockerfile: document the T08 guarantee (no secret ARG/ENV, fixed non-secret
COPY paths, runtime credentials via Compose environment)
- compose.yaml: T08 in scope; runtime credentials stay in service environment,
never in the image
The runtime stage of apps/server/Dockerfile now drops root privileges with
'USER node' — the non-root user (uid/gid 1000) the official Node image ships
with — so the app container does not run with root privileges. The server
binds port 3000 (>= 1024) and only reads the root-owned files copied above,
so no extra user creation or ownership changes are required. compose.yaml
header updated: T05 is in scope; T06 (read-only rootfs) and T07 (multi-arch)
remain out of scope.
Mount the named `db-data` volume at PostgreSQL's data directory
(/var/lib/postgresql/data) on the db service and declare it in the
top-level volumes map, so the database survives `docker compose
restart` and `docker compose down` + `up -d` (recreate). Reset with
`docker compose down -v` per the issue rollback note. Header comments
in compose.yaml and the server Dockerfile updated: T04 is no longer out
of scope; T05/T06 remain.
Switch the app image from node:24-alpine to node:24.19.0-bookworm-slim in
both build and runtime stages (Technology-Stack 5.4: glibc Debian base
required because argon2 is a native dependency; musl/Alpine causes
native-module build surprises), and the db image from postgres:16-alpine
to postgres:18-bookworm (Technology-Stack 5.2/5.4/6.2 + golden tuple 7
pin PostgreSQL 18.6; 18-bookworm is the 18.x line on Debian bookworm).
Update tests/compose-config.test.mjs so the committed assertions lock in
the corrected image bases (db image, Dockerfile build/runtime stages,
parser probe).
