The Build Stage (build.yml)

This is the most complex template. It downloads the "Locked Box" and then runs a full integration test before zipping up the final code artifact.

Key Features:

• DownloadPipelineArtifact@2: This task downloads the php-build-[PROJECT-NAME] artifact from the "Factory" pipeline (buildType: 'specific').
• gunzip -c ... | docker load: This is the other half of our gzip optimization. It decompresses the image in memory and pipes it directly into docker load. This is faster than writing the uncompressed file to disk first.
• Manual Docker Networking: This is the most critical part. We cannot use the services: block because it creates a race condition (it runs before steps:). The only stable way to get Docker-in-Docker containers to talk is:
  1. Manually create a network: docker network create ci-net.
  2. Manually start mysql: docker run --name mysql --network=ci-net ....
  3. Manually attach all other containers: docker run --network=ci-net .... This adds 15 seconds but guarantees a 100% stable build, which is a worthwhile trade.
• Inclusion zip: The zip command explicitly lists only the folders needed for deployment. This is safer than an exclusion-based approach, as it ensures no junk files (.DS_Store, .idea) ever make it into the artifact.
