The nginxinc/nginx-unprivileged base image already includes a perfectly suitable HEALTHCHECK instruction that uses curl. By specifying a new HEALTHCHECK, you are overriding this proven implementation. It's better to remove this custom HEALTHCHECK and let the Dockerfile inherit the one from the base image. This simplifies the Dockerfile and relies on the base image's tested configuration.

The X-XSS-Protection header is deprecated and can introduce security vulnerabilities in some older browsers. Modern browsers do not support it and rely on a strong Content-Security-Policy (CSP) for protection against XSS. Since you already have a CSP in place, this header should be removed to align with current security best practices.

build.context is set to .. (repo root), so Docker will only honor a .dockerignore located at the repo root. The per-image ignores in docker/backend/.dockerignore and docker/web/.dockerignore won’t be applied during docker compose build, which can bloat build context and accidentally send unnecessary files to the daemon/CI. Consider adding a single root .dockerignore suitable for both builds, or change each service’s build context to its own directory and adjust COPY paths accordingly.

This .dockerignore won’t be used by the current build configuration: both docker compose and the CI workflow build the backend with context set to the repo root, and Docker only reads .dockerignore from the build context root. If you want backend-specific ignore rules, switch the backend build context to docker/backend/ (and vendor/copy required sources into that context) or consolidate ignore rules into a single root .dockerignore.

This .dockerignore won’t be used by the current build configuration: both docker compose and the CI workflow build the web image with context set to the repo root, and Docker only reads .dockerignore from the build context root. Either add a single root .dockerignore (that still includes web/) or change the web build context to docker/web/ and update COPY paths accordingly.

Using aquasecurity/trivy-action@master makes the workflow non-reproducible and increases supply-chain risk because the action can change without review. Pin Trivy to a released version tag or (preferably) a commit SHA, consistent with the rest of the workflow’s security goals.

trivy-action@master is an unpinned mutable ref

aquasecurity/trivy-action@master resolves to whatever the upstream repo's master branch points to at workflow runtime — any commit pushed there automatically takes effect in your CI without review. This is a supply chain attack vector, and it is inconsistent with every other action in this workflow, which pins to a specific immutable version tag (e.g. @v3, @v5, @v6).

Pin this to a specific release tag or, ideally, a full commit SHA. The same issue appears in the build-web job (line 163).

Vulnerable images land in GHCR before scanning

The "Build and push" step (line 70) uses push: true, which publishes the image to GHCR unconditionally. The Trivy and Grype vulnerability scans only run after the image is already public (lines 85–98). If a scan fails and the workflow is cancelled or the image is never deleted, a critical-severity image remains in the registry.

The same sequencing problem exists in build-web (lines 147–175).

The idiomatic fix is a two-step approach: build to the local Docker daemon (or export as a tarball) for scanning, then push only when all scans pass:

# Step 1 — build only (no push), load into local daemon for scanning
- name: Build (no push)
  id: build

Missing Content-Security-Policy header; X-XSS-Protection is deprecated

Two issues with the security headers block:

1. Content-Security-Policy is absent. CSP is widely considered the most impactful browser security header — it controls which origins scripts, styles, and other resources may load from and is the primary mitigation against XSS. Even a restrictive default policy like default-src 'self' (with script-src 'unsafe-inline' relaxed once a real JS bundle exists) would meaningfully raise the security posture of this container.

2. X-XSS-Protection "1; mode=block" is deprecated. This header was removed from Chromium in version 78 and from the living standard. Modern browsers ignore it entirely; some older Webkit-based browsers had documented bypass vulnerabilities when it was enabled. It can be safely removed.

🧹 Nitpick | 🔵 Trivial

Version extraction lacks error handling.

If tool.commitizen.version is missing or the file is malformed, the step will fail with an unhelpful error. Consider adding validation.

       - name: Extract version from pyproject.toml
         id: version
         run: |
-          VERSION=$(python3 -c "import tomllib; print(tomllib.load(open('pyproject.toml','rb'))['tool']['commitizen']['version'])")
+          VERSION=$(python3 -c "
+import tomllib
+import sys
+try:
+    data = tomllib.load(open('pyproject.toml', 'rb'))

+except (KeyError, FileNotFoundError) as e:
+    print(f'::error::Failed to extract version: {e}', file=sys.stderr)
+    sys.exit(1)
+          ")
           echo "app_version=${VERSION}" >> "$GITHUB_OUTPUT"
           echo "App version: ${VERSION}"

error message to stderr and exit non‑zero on failure, and only write app_version
to GITHUB_OUTPUT and echo the version when validation succeeds.

🧹 Nitpick | 🔵 Trivial

Vulnerability scans run after image is pushed to registry.

The current order builds and pushes the image (lines 70-83), then runs scans (lines 85-98). If a scan fails, a potentially vulnerable image is already public in GHCR. Consider building without pushing first, scanning locally, then pushing only if scans pass.

Verify each finding against the current code and only fix it if needed.

In @.github/workflows/docker.yml around lines 70 - 98, The workflow currently
builds and pushes the image in the "Build and push" step (uses:
docker/build-push-action@v6 with push: true) before running Trivy
(aquasecurity/trivy-action@master) and Grype (anchore/scan-action@v6) scans;
change it to build without pushing by setting push: false and load: true in the
docker/build-push-action@v6 step (id: build) so the image is available locally,
run the Trivy and Grype steps against that local image reference (use the same
tags/output name produced by the build), and only after both scans succeed add a
separate push step (either a second docker/build-push-action@v6 invocation with
push: true or an explicit docker push) to publish the image.

⚠️ Potential issue | 🟠 Major

Pin Trivy action to a specific version instead of @master.

Using @master for the Trivy action is a security risk (supply chain attack vector) and can cause unexpected breakages. Pin to a specific version tag for reproducibility.

consistently uses a fixed, reviewed release instead of the master branch.

Fix the copy command path.

These instructions only work after cd docker/, but the rest of the PR documents repo-root usage. From the repo root, this should point at docker/.env.example and docker/.env.

⚠️ Potential issue | 🟠 Major

Remove or update the misleading file comment; override file is not auto-merged when using -f docker/compose.yml.

Docker Compose only auto-merges compose.override.yml when file discovery is enabled (no -f flags). With the documented docker compose -f docker/compose.yml ... flow, the override file is ignored unless explicitly passed as a second -f argument. Either update the comment to reflect this, remove the override file, or switch to default file discovery to use it.

the comment to say to include it explicitly with `-f docker/compose.yml -f
docker/compose.override.yml`, (b) remove the override file if you won't rely on
discovery, or (c) switch CI/dev scripts to use file discovery so the override is
picked up; make the change in the compose.override.yml header comment so the

Move these ignore rules to .dockerignore at the repository root.

The build context for both docker/web/Dockerfile and docker/backend/Dockerfile is . (repository root), so Docker never reads docker/web/.dockerignore or docker/backend/.dockerignore. Without any ignore file, the entire repository—including .git/, tests/, src/, etc.—is sent to the Docker builder, increasing build time and exposing unnecessary files. Create a root-level .dockerignore with consolidated rules from both files, or rename each to docker/[service]/Dockerfile.dockerignore (though the root .dockerignore approach is more standard).
