GitHub actions

• github.com's automation framework
• usually used for CI/CD
• event driven

Workflow

• automation yaml file
• lives at .github/workflows
• contains one or more jobs

Job

• a collection of steps
• runs on an individual compute instance - runner
• by default jobs have no dependencies and run in parallely (if enough runners are available)

Steps

• tasks that run in the context of a job's runner
• consist of a shell command or an action
• share files
• changes to env vars don't carry over to the next step

Action

• actions are the superpower of GitHub actions
• a pre-defined, reusable set of jobs or code that performs specific tasks
• you can find actions in the GitHub Marketplace
• you can write your own actions (three types: container, JavaScript and composite)
