A simple Github action to get the latest commit hash and description from another repository. No authentication required. This is adapted from pozetroninc/github-action-get-latest-release because the repo I was automating builds for do not create releases and I need to tag my docker builds.
Example Repository - https://github.com/nmbgeek/github-action-get-latest-commit
Inputs
| Name | Description | Example |
|---|---|---|
| owner | The Github user or organization that owns the repository | nmbgeek |
| repo | The repository name | github-action-get-latest-commit |
or
| Name | Description | Example |
|---|---|---|
| repository | The repository name in full | nmbgeek/github-action-get-latest-commit |
Additional Inputs (Optional)
| Name | Description | Example |
|---|---|---|
| branch | Specify branch. If blank the default branch, usually main, will be used. | |
| token | GitHub token or personal access token | ${{ secrets.GITHUB_TOKEN }} or ${{ secrets.PERSONAL_ACCESS_TOKEN }} |
Using the GITHUB_TOKEN will avoid the action failing due to hitting API rate limits from the IP address of the GitHub runner your action is running on. Using a PERSONAL_ACCESS_TOKEN is required to get the release information from a private repo. You can read about how to create a personal access token here and how to add this as a repository secret here.
Outputs
