Pack CLI Concourse Resource

You should probably look at using the lifecycle-build task instead of this resource.

A proof of concept concourse resource that builds OCI images using the pack-cli

Uses Docker in Docker so must be run a privileged.

It borrows heavily from the docker-image-resource

It utilizes the in and check behaviours from the registry-image-resource

Currently will only work with buildpacks that are build using pack > v0.0.9

Source Configuration

  • repository: Required. The name of the repository that you want to build e.g bstick12/built-with-pack
  • tag: Optional. The tag value for the image. Defaults to latest
  • username: Required. The username to authenticate with when pushing
  • password: Required. The password to use when authenticating

Behaviour

check: Discover new digests

See registry-image-resource/check

in: Fetch the image's rootfs and metadata

See registry-image-resource/in

out: Build an OCI image using the pack CLI and push to a repository

Parameters

  • build: Required. The source code to build in to the OCI image.
  • builder: Optional. The builder to use to build the OCI image.
  • tag: Optional. Name of tag. Defaults to latest. Overridden by tag_file.
  • tag_file: Optional. The value should be a path to a file containing the name of the tag.
  • tag_prefix: Optional. If specified, the tag read from the file will be prepended with this string. This is useful for adding v in front of version numbers.
