Summary of Changes

Hello @kabir, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request resolves a critical build issue by updating the base Docker image used in the multi-instance replicated queue manager test environments. The previous openjdk:17-slim image had become unavailable, and this change replaces it with mirror.gcr.io/eclipse-temurin:17-jre-jammy to ensure the tests can continue to build and run correctly.

Highlights

  • Docker Image Update: The base Docker image for the multi-instance replicated queue manager tests has been updated from openjdk:17-slim to mirror.gcr.io/eclipse-temurin:17-jre-jammy.
  • Resolution of Missing Image: This change addresses the issue where the openjdk:17-slim image was no longer available, preventing successful builds for the test environments.

Code Review

This pull request correctly addresses a build failure by replacing the openjdk:17-slim base image, which is no longer available, with mirror.gcr.io/eclipse-temurin:17-jre-jammy. The change is applied consistently across both test application Dockerfiles. My review includes a suggestion to pin the new base image to a specific digest to ensure build reproducibility and enhance security, which is a recommended practice for managing Docker images.

For improved build reproducibility and security, it's a best practice to pin the Docker base image to its immutable SHA256 digest. This prevents unexpected changes if the 17-jre-jammy tag is updated in the future.

You can obtain the digest by pulling the image and inspecting it:

  1. docker pull mirror.gcr.io/eclipse-temurin:17-jre-jammy
  2. docker inspect mirror.gcr.io/eclipse-temurin:17-jre-jammy (look for RepoDigests)

Then, you can update the FROM line to include the digest, for example:

FROM mirror.gcr.io/eclipse-temurin:17-jre-jammy@sha256:...
