JasonEtco / Upload To Release

Upload to Release

A GitHub Action that uploads a file to a new release.

Usage

This action uploads any file to a new release:

One example workflow is to build and save a Docker image then upload it to a release:

# .github/workflows/build-docker-image.yml
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/[email protected]

      - name: Build Docker image
        uses: actions/docker/[email protected]
        with:
          args: build . -t my-image

      - name: Save the image
        uses: actions/docker/[email protected]
        with:
          args: save my-image:latest

      - name: Upload to release
        uses: JasonEtco/[email protected]
        with:
          args: my-image.tar
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Requirements

You must pass at least one argument, the path to the file you want to attach. You must also include the GITHUB_TOKEN secret, otherwise uploading the file will not work.

- name: Upload to release
  uses: JasonEtco/[email protected]
  with:
    args: my-image.tar
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Content-Type

You may also need to pass an additional argument, the Content-Type header used when uploading your file (this is application/zip by default):

- name: Upload to release
  uses: JasonEtco/[email protected]
  with:
    args: my-image.tar application/zip
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Event type

The event type your workflow is triggered from is critical to the function of this action. If you are not using on: release for your workflow this action will not work correctly.

The event sent to the action by GitHub only contains an artifact upload URL when using the release event type to trigger the workflow.

If you need other workflows not based on the release event, you should use multiple workflow definitions.
