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.
