Docker Build

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

``bash GIT_SHA=$(git rev-parse --short HEAD) TIMESTAMP=$(date +%Y%m%d-%H%M%S) TAG="${GIT_SHA}-${TIMESTAMP}" ``

1. Build with cache busting when needed

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

1. Verify the build

``bash docker images | grep docker inspect /:${TAG} | jq '.[0].Created' ``

1. Push to registry

``bash docker push /:${TAG} docker push /:-latest ``

1. Verify in registry

``bash # For ACR: az acr repository show-tags --name --repository --orderby time_desc --top 5 # For Docker Hub: docker manifest inspect /:${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
