create deployment deployment_status issue created pull_request push schedule label created
(and many more) Events trigger work fl ows

set up in your repository to build, test, package, release, or deploy source: GitHub.com
GitHub webhooks GitHub Actions work fl ows
Actions are individual tasks that you can combine to create
jobs source: GitHub.com
You can create custom Actions or use Actions provided by
the GitHub community source: GitHub.com

GitHub.com
Types of Actions: JavaScript Docker source: GitHub.com
“GitHub Actions is available with GitHub Free, GitHub Pro, GitHub
Team, and GitHub Enterprise” source: GitHub.com
What if I already have an existing CI tool enabled?
Keep your existing CI tool and enable GitHub Actions
Evaluate both CI tools running side-by-side

Hosted Runners “GitHub hosts Linux and Windows runners on Standard_DS2_v2
virtual machines in Microsoft Azure with the GitHub Actions runner application installed” source: GitHub.com

Self-Hosted Runners “do not use self- hosted runners with public
repositories” source: GitHub.com
Self-Hosted Runners “Forks of your public repository can potentially run
dangerous code on your self-hosted runner machine” source: GitHub.com
Final thoughts
“CI ensures that the code that we create, as a
team, works by providing us with rapid feedback on any problems”
