What is GitHub Actions?
GitHub Actions is a continuous integration and continuous delivery (CI/CD) platform that allows you to automate your software build, test, and deployment pipeline. It enables you to create custom workflows that can be triggered by specific events, such as push, pull requests, or schedule. With GitHub Actions, you can automate your development workflow, from code review to deployment, and ensure that your repositories stay clean and recovery stays fast.
Main Features of GitHub Actions
GitHub Actions provides a range of features that make it an ideal choice for automating your development workflow. Some of the main features include:
- Workflows: GitHub Actions allows you to create custom workflows that can be triggered by specific events.
- Actions: You can create custom actions that can be used in your workflows to perform specific tasks.
- Runners: GitHub Actions provides self-hosted runners that can be used to run your workflows.
How to Use GitHub Actions
Getting Started
To get started with GitHub Actions, you need to create a new workflow file in your repository. You can do this by going to your repository, clicking on the Actions tab, and then clicking on the New workflow button.
Step 1: Create a New Workflow File
Create a new file in your repository’s `.github/workflows` directory. Name the file `main.yml` or any other name that you prefer.
Step 2: Define Your Workflow
In the workflow file, you need to define the workflow and the actions that you want to perform. You can use YAML syntax to define your workflow.
Step 3: Configure Your Workflow
Once you have defined your workflow, you need to configure it to run on specific events. You can do this by specifying the triggers in your workflow file.
GitHub Actions Snapshot and Restore Workflow
What is a Snapshot?
A snapshot is a point-in-time image of your repository. GitHub Actions allows you to create snapshots of your repository at specific points in your workflow.
How to Create a Snapshot
To create a snapshot, you need to use the `actions/checkout` action in your workflow file. This action allows you to create a snapshot of your repository at a specific point in your workflow.
Example
| Code | Description |
|---|---|
| `actions/checkout@v2` | Creates a snapshot of the repository at the current point in the workflow. |
