Understanding Github Actions#

YouTube: Github Actions CI/CD - Everything you need to know to get started

Official Understanding Actions Docs. These are paraphrased below.

Workflows#

"A workflow is a configurable automated process that will run one or more jobs. Workflows are defined by a YAML file checked in to your repository and will run when triggered by an event in your repository, or they can be triggered manually, or at a defined schedule." (citation)

Workflows are placed in the .github/workflows/ directory at the root of your repository.

Understanding the Workflow File

Actions#

Prepackaged Github Actions workflows can be found in the Actions Marketplace in the 'Actions' tab for every repo. You can also create custom Actions.

Events#

Events are configured to trigger workflows. These can be schedules, changes to branches, the completion of other workflows, and much more. Github has thorough documentation on Workflow triggers and Events.

Jobs#

Jobs are the work defined to be done in a workflow. Jobs run concurrently unless configured otherwise.

Runners#

Runners are the servers that run Jobs.

See Action Runners page for more information.
