What is GitHub Actions?
GitHub Actions is a continuous integration and continuous delivery (CI/CD) tool that allows you to automate your software build, test, and deployment pipeline. With GitHub Actions, you can create custom workflows that automate tasks, such as building and testing your code, creating and deploying packages, and more. GitHub Actions is integrated directly into GitHub, making it easy to manage your workflows and automate your software delivery process.
Main Features of GitHub Actions
GitHub Actions has several key features that make it a powerful tool for automating your software delivery process. Some of the main features include:
- Customizable workflows: With GitHub Actions, you can create custom workflows that automate tasks specific to your project.
- Integration with GitHub: GitHub Actions is integrated directly into GitHub, making it easy to manage your workflows and automate your software delivery process.
- Support for multiple languages: GitHub Actions supports multiple programming languages, including Java, Python, JavaScript, and more.
How to Use GitHub Actions
Creating a New Workflow
To create a new workflow in GitHub Actions, you’ll need to create a new YAML file in the `.github/workflows` directory of your repository. This file will define the steps that your workflow will take.
For example, here is a simple workflow that builds and tests a Node.js project:
| File | Contents |
|---|---|
| .github/workflows/build-and-test.yml |
name: Build and Test on: [push] jobs: build-and-test: runs-on: ubuntu-latest steps: - name: Checkout code uses: actions/checkout@v2 - name: Install dependencies run: npm install - name: Build and test run: npm run build && npm run test |
Using GitHub Actions Snapshot and Restore Workflow
GitHub Actions provides a snapshot and restore workflow feature that allows you to save the state of your workflow and restore it later. This feature is useful for long-running workflows or workflows that require a lot of resources.
To use the snapshot and restore workflow feature, you’ll need to add the `actions/snapshot` and `actions/restore` steps to your workflow file.
