What is GitHub Actions?

GitHub Actions is a continuous integration and continuous deployment (CI/CD) tool that allows you to automate your software build, test, and deployment pipeline. It is a powerful tool that enables you to automate your workflow, ensuring that your code is built, tested, and deployed quickly and reliably. With GitHub Actions, you can automate your development workflow, from code review to deployment, and ensure that your repositories stay clean and your recovery stays fast.

Main Features of GitHub Actions

GitHub Actions has several key features that make it a powerful tool for automating your development workflow. These features include:

• Workflows: GitHub Actions allows you to define custom workflows that automate your development pipeline.
• Actions: GitHub Actions provides a range of pre-built actions that you can use to automate your workflow.
• Runners: GitHub Actions provides a range of runners that you can use to run your workflows.

Installation Guide

Step 1: Create a GitHub Actions Workflow File

To get started with GitHub Actions, you need to create a workflow file. This file defines the workflow that you want to automate. To create a workflow file, follow these steps:

1. In your GitHub repository, create a new file called `.github/workflows/main.yml`.
2. In this file, define the workflow that you want to automate. For example, you can define a workflow that builds and tests your code.

Step 2: Configure Your Workflow

Once you have created your workflow file, you need to configure your workflow. This involves defining the actions that you want to run, the runners that you want to use, and the triggers that you want to use.

For example, you can define an action that builds your code, and another action that tests your code. You can also define a runner that runs your workflow on a Linux machine.
