GitHub does currently not provide an easy way to download an artifact from the lastest successful GitHub Action build. This tool is meant to fill that gap.

Python 3.4+, no other dependencies

Simply clone this repository and call the github-artifact-download.py

GitHub currently restricts download of artifacts to authenticated users. That means that you need to create a Personal Access Token to use this tool. The token can either be supplied via an environment variable GITHUB_TOKEN, or using the --token argument. For public repositories, only the "public_repo" scope is required for this access token.

Only a single asset can be downloaded in one invokation of the tool. There are two modes of operation:

1. Find the latest artifact by name in all artifacts of the repository,
2. Find the latest successful run of a particular workflow and download a named artifact from that run.

After an artifact has been downloaded, it's full path on the local filesystem is printed to stdout. This is designed to help in additional (shell) scripts that further process the downloaded file.

To prevent re-downloading the same file again, you can specify a --cache-file filepath to which the asset id of the last downloaded file will be written. If the found asset matches the id in that file, it is skipped and the skript exists without outputting the filename.

Note: in the following examples, owner/repo is a placeholder for your target repositories owner and name. So to download artifacts from this repository for example, you would use mawe42/github-artifact-download (don't do this, there are not Actions set up here :-).

All examples below assume that your GitHub token is set in the environment:

export GITHUB_TOKEN=a345fd8e93...

Download latest artifact called "stuff" to a local file called stuff.zip

github-artifact-download.py owner/repo --artifact stuff

Download latest artifact called "stuff" into a file called artifact.zip

github-artifact-download.py owner/repo --artifact stuff --filename artifact.zip

Download latest artifact called "stuff" and make sure we don't download it again

github-artifact-download.py owner/repo --artifact stuff --cache-file id.txt

Download the artifact "stuff" from the last successful build of workflow "My Test Build"

github-artifact-download.py owner/repo --artifact stuff --workflow "My Test Build"

Download the artifact "stuff" from the last successful build of workflow "My Test Build", but only for builds on branch "test-build"

github-artifact-download.py owner/repo --artifact stuff --workflow "My Test Build" --branch test-build
