Image processing

As part of the build, the output image needs to be mutated (annotated and labeled), and pushed. This package contains Shipwright Build owned image processing code.

Features

• Mutate the image with annotations
• Mutate the image with labels
• Push the image

Development

Run the CLI code

• Run it locally:

  go run cmd/image-processing/main.go \
  --image $IMAGE \
  --annotation "org.opencontainers.image.url=https://my-company.com/images" \
  --label "maintainer=team@my-company.com" \
  [--insecure] \
  [--push some-local-dir-or-tarball]
  

  If we are trying to mutate the image in a private registry, authentication to the registry should be done before running the command.

• Run it using ko (base image defined in .ko.yaml)

    docker run \
      --rm \
      --volume $HOME/.docker/config.json:/.docker/config.json \
      -e DOCKER_CONFIG=.docker \
      $(KO_DOCKER_REPO=ko.local ko publish --bare ./cmd/image-processing) \
      --image $IMAGE \
      --annotation "org.opencontainers.image.url=https://my-company.com/images" \
      --label "maintaner=team@my-company.com"
