GitHub Actions is an automation platform provided by GitHub that allows you to define workflows to build, test, and deploy your code directly within your GitHub repository. It helps you automate various tasks and processes, making it easier to manage and maintain your software development lifecycle. Here are some basics of GitHub Actions:
It is Integrated CICD integration tool like Jenkins,

1. Workflow: A workflow is a set of automated processes defined in a YAML file within your repository under the .github/workflows directory. Workflows can be triggered by events such as pushes, pull requests, or scheduled intervals.
2. YAML File: GitHub Actions workflows are defined using a YAML file format. This file describes the jobs, steps, and actions that make up the workflow.
3. Jobs: A workflow can consist of one or more jobs. Each job represents a set of steps that run on the same runner (execution environment).
4. Steps: Steps are individual tasks that are executed in a job. Each step typically represents a command, action, or script to be run. Steps run sequentially by default, but you can define parallel steps as well.
5. Actions: Actions are reusable units of code that perform a specific task. They can be used within a workflow to execute common tasks like building, testing, or deploying. GitHub provides a marketplace where you can find and use actions created by the community.
6. Events: Workflows can be triggered by various events, such as push, pull request creation, pull request updates, schedule, etc. You can specify the events that should trigger your workflow in the workflow YAML file.
7. Runners: Runners are the environments where your workflows execute. GitHub provides hosted runners with various configurations (Linux, Windows, macOS) or you can use self-hosted runners on your own infrastructure.
8. Workflow Syntax Example: yaml Code: name: CI/CD Workflow on: push: branches:
9. main jobs: build: runs-on: ubuntu-latest steps:
10. name: Checkout code uses: actions/checkout@v2
11. name: Set up Node.js uses: actions/setup-node@v3 with: node-version: 14
12. name: Install dependencies run: npm install
13. name: Run tests run: npm test
14. name: Deploy to production if: success() run: | echo “Deploying to production…” # Add deployment steps here
15. Workflow Execution: Workflows run automatically based on the specified events. You can monitor workflow runs on the GitHub Actions tab of your repository. Each run includes information about the executed jobs, steps, and any errors that occurred.
16. Secrets: GitHub Actions allows you to store and use secrets (e.g., API keys, access tokens) securely. Secrets are encrypted and can be accessed within your workflow. GitHub Actions provides a powerful and flexible way to automate your software development processes, making it easier to maintain and scale your projects.
