If needed, revert this PR. The old catthehacker/ubuntu:act-latest image remains on disk for 2 weeks per the rollback strategy.

Testing

CI passes on the PR using the new image
Manual verification of workflow execution

PR Review: ci: promote custom slim runner image (ci-runner:1.0.0)

❌ Critical Concern: JDK Setup Incompatibility

The PR changes to Alpine-based container but retains actions/setup-java@v4 with zulu distribution in test_image_build_push.yml. This is incompatible.

Evidence from ci-runner-test PR #5:

The actions/setup-java@v4 step downloads a glibc-compiled Temurin JDK, which cannot execute on Alpine's musl libc — this causes ./gradlew build to fail.

Fix validated in ci-runner-test:
Replace:

- name: JDK setup
  uses: actions/setup-java@v4
  with:
    distribution: 'zulu'
    java-version: '17'

With:

- name: Install JDK (Alpine package)
  run: |
    apk add --no-cache openjdk17-jdk
    echo "JAVA_HOME=/usr/lib/jvm/java-17-openjdk" >> "$GITHUB_ENV"

✅ `prod_image_tag_promote.yaml` — No changes needed

The prod workflow only tags/pushes images (no Java compilation). The image swap alone is fine there.

Summary

test_image_build_push.yml: Must also update JDK setup (see above) — REQUEST CHANGES
prod_image_tag_promote.yaml: Approved as-is

Please update the JDK setup step to match the validated approach, then I'll approve.

⚠️ REVIEW DECISION: REQUEST CHANGES

I've reviewed the diff and the validation results from ci-runner-test. Here's my detailed feedback:

✅ What's Good

Pinned to :1.0.0 — deterministic builds, best practice
Consistent change across both workflow files
Clear rollback strategy (2-week retention of old image)
Thorough validation done in ci-runner-test repo

❌ Critical Issue: JDK Setup Incompatibility

test_image_build_push.yml changes the container to Alpine-based eclipse-temurin:17-jre-alpine, but retains actions/setup-java@v4 with zulu distribution. This will break the Gradle build.

Evidence from ci-runner-test PR #5 (titled "Fix Gradle build failure — replace setup-java with Alpine JDK package"):

The actions/setup-java@v4 step downloads a glibc-compiled JDK, which cannot execute on Alpine's musl libc. The error was:

/opt/hostedtoolcache/Java_Temurin-Hotspot_jdk/17.0.19-10/x64/bin/java: not found

The validated fix was to replace actions/setup-java@v4 with Alpine's native JDK:

- name: Install JDK (musl-native, Alpine package)
  run: |
    apk add --no-cache openjdk17-jdk
    echo "JAVA_HOME=/usr/lib/jvm/java-17-openjdk" >> "$GITHUB_ENV"

🔧 Required Change

Please update test_image_build_push.yml — replace the actions/setup-java@v4 step with the apk add openjdk17-jdk approach above.

✅ Approved As-Is

prod_image_tag_promote.yaml — This workflow only tags/pushes Docker images (no Java compilation). The image swap is fine.

Summary

File	Status
`test_image_build_push.yml`	REQUEST CHANGES — fix JDK setup
`prod_image_tag_promote.yaml`	✅ Approved

Once the JDK setup is updated to match the validated approach, I'll approve the PR.

Fixed the Alpine JDK compatibility issue. Here's the summary:

Problem: actions/setup-java@v4 downloads a glibc-compiled JDK, which crashes on the new Alpine-based ci-runner:1.0.0 container image.

Fix: Replaced the actions/setup-java@v4 step (lines 39-43) with Alpine-native JDK install using apk add --no-cache openjdk17-jdk and setting JAVA_HOME to /usr/lib/jvm/java-17-openjdk.

Diff:

-      - name: JDK setup
-        uses: actions/setup-java@v4
-        with:
-          distribution: 'zulu'
-          java-version: '17'
+      - name: Install JDK (Alpine package)
+        run: |
+          apk add --no-cache openjdk17-jdk
+          echo "JAVA_HOME=/usr/lib/jvm/java-17-openjdk" >> "$GITHUB_ENV"

This same fix was validated in ci-runner-test PR #5. PR #122 now auto-updates with the commit Hithomelabs/CFTunnels#122: replace actions/setup-java@v4 with Alpine-native JDK install for ci-runner container.
