Inline comments:
In @.github/workflows/cd.yml:
- Around line 3-6: The CD workflow currently triggers on push (on: push:
branches: [main]) which allows deployment even if CI failed; change the trigger
to use the workflow_run event so the CD only runs after the CI workflow
completes successfully — replace the on: push block with on: workflow_run:
workflows: ["CI"] (or the actual CI workflow name), types: [completed], and add
a conditional to the job(s) if needed to ensure
github.event.workflow_run.conclusion == 'success'; update any job-level if
expressions referencing github.ref to use
github.event.workflow_run.head_branch/head_sha where appropriate.
In @.github/workflows/ci.yml:
- Around line 44-49: The workflow step named "Run dependency check" currently
pins the action as dependency-check/Dependency-Check_Action@main which is a
branch ref; change it to the specific commit SHA for the v1.1.0 release (replace
`@main` with @<v1.1.0-commit-sha>) and add an inline comment indicating the
release version and SHA (e.g., "v1.1.0 - <commit-sha>") so the action is fixed
to a known release and the version is explicit.
In `@Dockerfile`:
- Around line 13-17: The RUN instruction in the Dockerfile installs tzdata
without suppressing recommended packages; update the RUN line that calls apt-get
install -y tzdata to include the --no-install-recommends flag so it becomes
apt-get install -y --no-install-recommends tzdata (keep the surrounding apt-get
update, timezone symlink/echo and rm -rf /var/lib/apt/lists/* steps intact) to
avoid pulling unnecessary recommended packages into the image.
- Around line 19-23: The Dockerfile hardcodes reaction-0.0.1-SNAPSHOT.jar in
both COPY and ENTRYPOINT causing builds to break on version changes; update the
Dockerfile to COPY the built jar using a wildcard (e.g., COPY --from=build
/app/build/libs/*.jar /app/), capture the actual filename into a Docker ARG/ENV
or rename the copied jar to a stable name (e.g., reaction.jar) so ENTRYPOINT can
reliably run java -jar reaction.jar; modify the ENTRYPOINT to reference the
stable name or the ARG (java -jar ${JAR_NAME}) and ensure the build stage still
outputs a single jar to avoid ambiguous wildcard matches.
- Around line 9-23: The Dockerfile currently runs the image as root; add a
non-root user and switch to it before ENTRYPOINT to avoid running as root
(address DS-0002). In the Dockerfile create a user/group (e.g., appuser), set
ownership of the copied artifact (reaction-0.0.1-SNAPSHOT.jar) to that user
(chown), and add a USER appuser line so the ENTRYPOINT ["java", "-jar",
"reaction-0.0.1-SNAPSHOT.jar"] runs unprivileged; ensure any directories the app
needs (WORKDIR /app) are writable by that user.

GitHub action security best practices pinning commit SHA version tags
💡 Result:
GitHub Actions security best practices for version pinning (commit SHA vs tags)
- Prefer pinning every third‑party action to a full, immutable commit SHA (40 chars) rather than a branch or tag, to reduce supply‑chain risk (tags can be moved). Example:
uses: actions/checkout@692973e3d937129bcbf40652eb9f2f61becf3332 # v4.1.7[1][2] - Pin SHAs that correspond to a published release/tag, and add a comment with the human version (e.g.,
# v4.1.7) to keep workflows readable and updateable. [2] - Verify the SHA is from the action’s official repository (not a fork) before pinning. [1]
- Keep pinned SHAs updated with automation (e.g., Dependabot “version updates” for Actions) so you don’t trade supply‑chain risk for stale dependencies. [2]
- Enforce SHA pinning via policy (org/repo/enterprise settings) so unpinned workflows can’t be introduced. [1][3]
- Audit third‑party actions you rely on (especially those that touch secrets or repo contents). [1]

dependency-check/Dependency-Check_Action을 @main으로 고정하면 공급망 위협 발생
@main은 브랜치 참조이므로 해당 액션 저장소의 변경이 즉시 워크플로우에 영향을 미칩니다. GitHub 보안 강화 가이드라인은 서드파티 액션을 특정 커밋 SHA로 고정할 것을 권장합니다.
해당 액션은 v1.1.0(최신 릴리스, 2021년 4월)이 존재합니다. 다음과 같이 릴리스 버전의 커밋 SHA로 고정하고 버전 주석을 추가하세요:
- uses: dependency-check/Dependency-Check_Action@main
+ uses: dependency-check/Dependency-Check_Action@75ba02d6183445fe0761d26e836bde58b1560600 # v1.1.0이렇게 하면 공급망 위협을 줄이면서도 어떤 릴리스 버전을 사용하고 있는지 명확하게 유지할 수 있습니다.

하드코딩된 SNAPSHOT JAR 이름으로 인한 버전 변경 시 빌드 실패
reaction-0.0.1-SNAPSHOT.jar이 COPY와 ENTRYPOINT 양쪽에 하드코딩되어 있어, build.gradle.kts에서 버전이나 아카이브명이 변경되면 Docker 빌드가 즉시 실패합니다. 와일드카드로 복사 후 고정 이름으로 변경하는 방식이 표준입니다.
