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

• 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.
