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
