Action Inputs

Input Name	Description	Default
stackerfile	the yaml file to be built as an OCI image, example: stacker.yaml	stacker.yaml
layer-type	output layer type (supported values: tar, squashfs), ca be both separated by whitespace	tar
substitutes	variable substitution in stackerfile, see stacker.yaml doc	None
url	remote OCI registry + repo name eg: docker://ghcr.io/project-stacker/	None
tags	one or more tags to give the new image, separated by whitespace	None
username	used to login to registry	None
password	used to login to registry	None
skip-tls	used with unsecure (http) registries	false

Build only example:

- name: Run stacker-build
  uses: project-stacker/stacker-build-push-action@main
  with:
    stackerfile: 'test/stacker.yaml'
    substitutes: 'SUB1=VAR1 SUB2=VAR2 SUB3=VAR3'
    layer-type: 'tar squashfs'

Publish url is built according to the next logic:

input.url + stacker.yaml container name + : + input.tag

Build and push example to ghcr.io:

- name: Run stacker-build
  uses: project-stacker/stacker-build-push-action@main
  with:
    stackerfile: 'test/stacker.yaml'
    substitutes: 'SUB1=VAR1 SUB2=VAR2 SUB3=VAR3'
    layer-type: 'tar squashfs'
    tags: ${{ github.event.release.tag_name }} latest
    url: docker://ghcr.io/${{ github.repository }}
    username: ${{ github.actor }}
    password: ${{ secrets.GITHUB_TOKEN }}

The above action will build test/stacker.yaml and push it to

1. docker://ghcr.io/project-stacker/stacker/test:latest
2. docker://ghcr.io/project-stacker/stacker/test:${{ github.event.release.tag_name }}

Build and push example to localhost:

- name: Run stacker-build
  uses: project-stacker/stacker-build-push-action@main
  with:
    stackerfile: 'test/stacker.yaml'
    substitutes: 'SUB1=VAR1 SUB2=VAR2 SUB3=VAR3'
    layer-type: 'tar squashfs'
    url: docker://localhost:5000
    skip-tls: true
    tags: test

The above action will build test/stacker.yaml and push it to

1. docker://localhost:5000/test:test
