What are GitHub Actions concepts?

Definition:

GitHub Actions defines automated workflows triggered by repository or scheduled events. Workflows contain jobs that run on runners, and jobs contain ordered steps using commands or reusable actions. Artifacts and outputs move results between steps or jobs, while permissions control what the workflow may access.

Key points:

• A workflow runs on events such as a push or pull request.

• Jobs run on runners; steps run commands or reusable actions.

• Scope credentials carefully and protect deployment environments.

• Treat untrusted pull-request content carefully when credentials or write permissions are available.

Interview point:

• Separate source checks from privileged deployment work and grant the minimum permissions each job needs.
