Day 7: Upload files to GitHub releases

December 07, 2019

upload-to-release by Jason Etcovich is an action which upload files into a release.

Example Usage

Say one manually creates a release, you can have a workflow that could build a docker image and upload the .tar output as a result. To run this, use the release trigger.

name: build-docker-image
on: release
jobs:
  build-docker-image:
    name: Build and upload docker image
    runs-on: ubuntu-latest
    steps:
      - name: Pull source
        uses: actions/checkout@v1
      - name: Build Docker image
        uses: actions/docker/cli@master
        with:
          args: build . -t my-image
      - name: Save the image
        uses: actions/docker/cli@master
        with:
          args: save my-image:latest
      - name: Upload to release
        uses: JasonEtco/upload-to-release@master
        with:
          args: my-image.tar
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

GITHUB_TOKEN is the only required secret and the args file takes a relative file and will attach it to the release.
