Workflows automate tasks in your software development lifecycle. Many tasks that you manually complete can be converted to a GitHub Actions workflow. You can use and customize pre-written actions to power your workflow. You can script with GitHub CLI in GitHub Actions workflows. You can use GitHub Actions workflows to run scripts. Learn how to create secrets at the repository, environment, and organization levels for GitHub Actions workflows.

GitHub Actions makes software development easier by automating common tasks right inside your GitHub repository. Rather than switching between different tools, developers can focus on writing code while GitHub Actions handles testing, deployment, and other routine work. Consider how it can automatically run tests whenever code changes are pushed - this helps catch issues early before they become bigger problems. Teams that use GitHub Actions see several key advantages: The result? Teams can release better code more quickly.

Plus, GitHub Actions offers plenty of example workflows that teams can customize for their specific needs. The flexibility of GitHub Actions shines through its many practical uses. Here are some common ways development teams put it to work: Since its 2019 launch, over 30% of open-source projects on GitHub now use GitHub Actions for their CI/CD needs. Teams appreciate how smoothly it fits into GitHub and its ability to test code across different environments. Learn more about GitHub Actions workflows here.

The GitHub Marketplace also offers pre-built actions that make it easy to add common automations. GitHub Actions workflows can automate tasks throughout the software development lifecycle. GitHub provides workflow templates for a variety of languages and tooling. You can configure workflows to run on a schedule or to run when certain events happen. You can specify the compute environment your jobs and workflows run in. Workflows automate tasks in your software development lifecycle.

Many tasks that you manually complete can be converted to a GitHub Actions workflow. As a developer who has spent countless hours automating workflows and optimizing CI/CD pipelines, I want to share an in-depth guide on GitHub Actions and Workflows. This comprehensive guide will take you from the basics to advanced concepts, helping you automate your development workflow effectively. GitHub Actions is a powerful automation platform that enables you to automate your software development workflows right in your GitHub repository. Think of it as your personal robot assistant that can perform tasks whenever certain events happen in your repository. Let's break down a typical workflow file structure:

This is what appears in your GitHub Actions tab. Choose descriptive names! Global variables available throughout the workflow. Software development doesn’t end when you write code — you also need to test, build, and deploy it. Doing these steps manually is time-consuming and error-prone. That’s where GitHub Actions comes in.

With GitHub Actions, you can automate workflows directly inside your GitHub repository — from running tests to deploying apps — without needing external CI/CD tools. This guide introduces GitHub Actions, explains its key concepts, and walks through your first workflow. GitHub Actions is a CI/CD (Continuous Integration and Continuous Deployment) platform built into GitHub. It allows you to: Think of it as your automation engine inside GitHub. Learn about the concepts of workflows and actions in GitHub Actions.

Get a high-level overview of GitHub Actions workflows, including triggers, syntax, and advanced features. Learn about variables in GitHub Actions workflows. You can evaluate expressions in workflows and actions. Learn how to avoid duplication when creating a workflow. You can use and customize pre-written actions to power your workflow. You can search and browse actions directly in your repository's workflow editor.

From the sidebar, you can search for a specific action, view featured actions, and browse featured categories. You can also view the number of stars an action has received from the GitHub community. You can add an action to your workflow by referencing the action in your workflow file. The actions you use in your workflow can be defined in: You can view the actions referenced in your GitHub Actions workflows as dependencies in the dependency graph of the repository containing your workflows. For more information, see “About the dependency graph.”

To enhance security, GitHub Actions does not support redirects for actions or reusable workflows. This means that when the owner, name of an action's repository, or name of an action is changed, any workflows using that action with the previous name will fail. A workflow is a configurable automated process made up of one or more jobs. You must create a YAML file to define your workflow configuration. Workflow files use YAML syntax, and must have either a .yml or .yaml file extension. If you're new to YAML and want to learn more, see Learn YAML in Y minutes.

You must store workflow files in the .github/workflows directory of your repository. The name of the workflow. GitHub displays the names of your workflows under your repository's "Actions" tab. If you omit name, GitHub displays the workflow file path relative to the root of the repository. The name for workflow runs generated from the workflow. GitHub displays the workflow run name in the list of workflow runs on your repository's "Actions" tab.

If run-name is omitted or is only whitespace, then the run name is set to event-specific information for the workflow run. For example, for a workflow triggered by a push or pull_request event, it is set as the commit message or the title of the pull request.
