GitHub Actions

GitHub Actions enables us to create custom software development life-cycle workflows directly in the GitHub repository

It is a platform to automate developer (any users) workflows

How GitHub Actions automate workflows?

• When something happens in or to the repository.In GitHub these are know as GitHub events such as Pull Requests, Issue created, New Contributors, etc.
• Listen to these events and trigger workflow. Automatic actions are executed in response

Some examples of workflows:

• Running tests, linting and other tasks whenever something happens to the repository

Most common workflow includes CI/CD pipelines

Note

Commit code --> Test --> Build --> Push --> Deploy

Why use GitHub Actions as a CI/CD tool?

• use same tool instead of third-party integration if the code already exists in GitHub
• setting up pipelines are easy.
• developers focused.
