A GitHub Action is a reusable automation component that performs a step or operation within a GitHub Actions workflow.
- How it is used
- Builds CI/CD workflows from reusable steps executed by GitHub-hosted runners.
- How deep it goes
- Demonstrates YAML references and a k3d deployment action, but defers action implementation internals.
- Examples
- Uses repository checkout, PowerShell builds, and a community k3d action that creates a temporary Kubernetes cluster.
- What you can do after
- Builds workflows with referenced actions and combines them with locally testable scripts.

- How it is used
- Automates repeatable workflow steps during application deployment.
- How deep it goes
- Demonstrates action selection and configuration, but does not explain action implementation internals.
- Examples
- Uses artifact download, Google Play upload, and TestFlight upload actions in one deployment job.

Automating API Delivery
A GitHub Actions action is a custom application that performs a reusable task within a GitHub Actions workflow.
- How it is used
- Automates repeatable build, test, checkout, and setup tasks inside GitHub Actions workflows.
- How deep it goes
- Defines actions within sequential workflow steps and shows configuration, but does not describe action internals.
- Examples
- Uses checkout, Java setup, compilation, unit testing, API linting, and breaking-change checks in a pull-request workflow.
- What you can do after
- Operate/configure reusable workflow steps that automate repository builds and enforce selected API quality controls.
