docker-build（Docker 构建）

Docker Build with Tracking

Build a Docker image with proper tagging and tracking: $ARGUMENTS

Process

1. Determine the image tag - Use git SHA or timestamp, NEVER use :latest alone GIT_SHA=$(git rev-parse --short HEAD) TIMESTAMP=$(date +%Y%m%d-%H%M%S) TAG="${GIT_SHA}-${TIMESTAMP}"
2. Build with cache busting when needed

- For production builds: docker build --no-cache --pull -t <registry>/<image>:${TAG}. - For dev builds: docker build -t <registry>/<image>:${TAG}. - Always also tag as :<branch>-latest for convenience

1. Verify the build docker images | grep <image> docker inspect <registry>/<image>:${TAG} | jq '.[0].Created'
2. Push to registry docker push <registry>/<image>:${TAG} docker push <registry>/<image>:<branch>-latest
3. Verify in registry # For ACR: az acr repository show-tags --name <registry> --repository <image> --orderby time_desc --top 5 # For Docker Hub: docker manifest inspect <registry>/<image>:${TAG}

Anti-Patterns (DO NOT)

• Never build with just :latest tag
• Never skip pushing after building
• Never deploy without verifying the image exists in the registry
• Never use imagePullPolicy: IfNotPresent with mutable tags
