GitHub Action - Releases API

Please note: This repository is currently unmaintained by a team of developers at GitHub. The repository is here and you can use it as an example, or in Actions. However please be aware that we are not going to be updating issues or pull requests on this repository.

Maintained Actions:

To reflect this state we’ve marked this repository as Archived.

If you are having an issue or question about GitHub Actions then please contact customer support.

If you have found a security issue please submit it here.

This GitHub Action (written in JavaScript) wraps the GitHub Release API, specifically the Upload a Release Asset endpoint, to allow you to leverage GitHub Actions to upload release assets.

GitHub Actions status

Usage

Pre-requisites

Create a workflow .yml file in your repositories .github/workflows directory. An example workflow is available below. For more information, reference the GitHub Help Documentation for Creating a workflow file. You also will need to have a release to upload your asset to, which could be created programmatically by @actions/create-release as show in the example workflow.

Inputs

For more information on these inputs, see the API Documentation

  • upload_url: The URL for uploading assets to the release, which could come from another GitHub Action, for example the @actions/create-release GitHub Action

Outputs

For more information on these outputs, see the API Documentation for an example of what these outputs look like

  • id: The ID of the asset
  • browser_download_url: The URL users can navigate to in order to download the release asset. i.e. https://github.com/octocat/Hello-World/releases/download/v1.0.0/example.zip

Example workflow - upload a release asset

On every push to a tag matching the pattern v*, create a release and upload a release asset. This Workflow example assumes you have the @actions/create-release Action in a previous step:

on:
  push:
    # Sequence of patterns matched against refs/tags
    tags:
    - 'v*' # Push events to matching v*, i.e. v1.0, v20.15.10

name: Upload Release Asset

jobs:
  build:
    name: Upload Release Asset
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v2
      - name: Build project # This would actually build your project, using zip for an example artifact
        run: |
          zip --junk-paths my-artifact README.md
      - name: Create Release
        id: create_release
        uses: actions/create-release@v1
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        with:
          tag_name: ${{ github.ref }}
          release_name: Release ${{ github.ref }}
          draft: false
          prerelease: false
      - name: Upload Release Asset
        id: upload-release-asset 
        uses: actions/upload-release-asset@v1
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        with:
          upload_url: ${{ steps.create_release.outputs.upload_url }} # This pulls from the CREATE RELEASE step above, referencing it's ID to get its outputs object, which include a `upload_url`. See this blog post for more info: https://jasonet.co/posts/new-features-of-github-actions/#passing-data-to-future-steps 
          asset_path: ./my-artifact.zip
          asset_name: my-artifact.zip
          asset_content_type: application/zip

This will upload a release artifact to an existing release, outputting the browser_download_url for the asset which could be handled by a third party service, or by GitHub Actions for additional uses. For more information, see the GitHub Documentation for the upload a release asset endpoint.
