- compose-config.test.mjs: assertDbService requires the pinned
postgres:18.6-bookworm image; new docker-gated real-stack probe starts the
stack and asserts SHOW server_version exposes 18.6; mutation probe proves
reverting to a floating major tag fails the criterion; parser probe updated
- build-targets.test.mjs: db-service mutation fixture updated to the pinned
image tag
- compose.yaml: db.image pinned to postgres:18.6-bookworm (exact 18.6 minor,
same bookworm flavor, no Alpine drift) so the database container is
reproducible and exposes the expected PostgreSQL version; document the
rollback (revert image to postgres:18-bookworm)
- .gitea/workflows/ci.yml: new compose-config job runs
tests/compose-config.test.mjs on every PR so the pinned-version criterion
gates merges (docker-gated real-stack probes skip cleanly without a daemon)
The Docker-gated probe only planted a root-level .env.t08-* marker, which no
Dockerfile COPY instruction ever copies — so it could not observe a nested
build-context leak in the image layers. Plant additional marker files at
nested paths the Dockerfile's COPY apps/server apps/server would sweep into
the build-stage image (apps/server/.env.t08-*, apps/server/secrets/t08-*.pem)
so the end-to-end scan actually verifies the 'any depth' exclusion
guarantee, not just the root form.
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.
tests/secrets-not-embedded.test.mjs: static assertions that the Dockerfile
embeds no secrets (no secret-bearing ARG/ENV, no secret-path or blanket COPY)
and .dockerignore excludes env/credential files; non-vacuous mutation probes
for every assertion; Docker-gated probe that builds the image with a marker
env file in the context and scans every layer + image config for secret
values.
- .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
tests/non-root-user.test.mjs locks in both acceptance criteria: a static
assertion that the Dockerfile runtime stage declares a non-root USER (not
root/uid 0, 'USER node' exactly), non-vacuous mutation probes, and a
Docker-gated real-stack probe that starts the stack and asserts 'id -u' and
'id -un' inside the running app container report a non-root user, with the
health endpoint still answering as a regression guard.
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.
compose-config: assert the db service mounts the named db-data volume at
the PostgreSQL data directory and the top-level volumes map declares it;
non-vacuous mutation probes (missing mount, missing volume declaration,
wrong mount target all fail); Docker-gated real-stack probe writes a
fixture row and asserts it survives `docker compose restart` (restart)
and `docker compose down` + `up -d` (recreate), cleaned up with
`docker compose down -v`.
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).
