Actions are sharable individual tasks that perform units of work; they allow you to automate and execute your software development workflows right in your repository.
Example use cases of GitHub Actions:
- Build a container and deploy a web service
- Automatically merge an approved pull request
- Welcome new users to your repository during onboarding
- Run unit tests against pull requests
Actions can be defined in multiple places:
- Directly in your repository
- In an open sourced public repository
- GitHub Marketplace
An event would trigger a workflow which uses an action to complete the job.
