What is Azure Pipelines?
Azure DevOps Services | Azure DevOps Server 2022 - Azure DevOps Server 2019 | TFS 2018
Azure Pipelines automatically builds and tests code projects. It supports all major languages and project types and combines continuous integration, continuous delivery, and continuous testing to build, test, and deliver your code to any destination.
Continuous Integration (CI) is the practice used by development teams of automating, merging, and testing code. CI helps to catch bugs early in the development cycle, which makes them less expensive to fix. Automated tests execute as part of the CI process to ensure quality. CI systems produce artifacts and feed them to release processes to drive frequent deployments.
The Build service in Azure DevOps Server helps you set up and manage CI for your applications.
Continuous Delivery (CD) is a process by which code is built, tested, and deployed to one or more test and production environments. Deploying and testing in multiple environments increases quality. CD systems produce deployable artifacts, including infrastructure and apps. Automated release processes consume these artifacts to release new versions and fixes to existing systems. Systems that monitor and send alerts run continually to drive visibility into the entire CD process.
Whether your app is on-premises or in the cloud, you can automate build-deploy-test workflows and choose the technologies and frameworks. Then, you can test your changes continuously in a fast, scalable, and efficient manner. Continuous testing offers the following benefits.
- Maintain quality and find problems as you develop. Continuous testing with Azure DevOps Server ensures your app still works after every check-in and build, enabling you to find problems earlier by running tests automatically with each build.
- Use any test type and any test framework. Choose your preferred test technologies and frameworks.
- View rich analytics and reporting. When your build is done, review your test results to resolve any issues. Actionable build-on-build reports let you instantly see if your builds are getting healthier. But it's not just about speed - detailed and customizable test results measure the quality of your app.
Version control systems
Azure Pipelines requires your source code to be in a version control system. Azure DevOps supports two forms of version control - Git and Azure Repos. Any changes you push to your version control repository are automatically built and validated.
Languages and applications
You can build, test, and deploy Node.js, Python, Java, PHP, Ruby, C#, C++, Go, XCode, .NET, Android, and iOS applications. Run these apps in parallel on Linux, macOS, and Windows.
Azure DevOps offers tasks to build and test .NET, Java, Node, Android, Xcode, and C++ applications. Similarly, there are tasks to run tests using many testing frameworks and services. You can also run command line, PowerShell, or Shell scripts in your automation.
Use Azure Pipelines to deploy your code to multiple targets. Targets include virtual machines, environments, containers, on-premises and cloud platforms, or PaaS services. You can also publish your mobile application to a store.
Once you have continuous integration in place, create a release definition to automate the deployment of your application to one or more environments. This automation process is defined as a collection of tasks.
To produce packages that can be consumed by others, you can publish NuGet, npm, or Maven packages to the built-in package management repository in Azure Pipelines. You also can use any other package management repository of your choice.
What do I need to use Azure Pipelines?
To use Azure Pipelines, complete the following tasks:
- Have an organization in Azure DevOps. If you don't have one, create an organization now.
- Store your source code in a version control system.
- Download a build agent and install it on a build server.
Pricing for Azure DevOps
Azure DevOps Services
If you use public projects, Azure Pipelines is free, but you will need to request the free grant of parallel jobs. You can request this grant by submitting a request. Existing organizations and projects are not affected.
For more information, see What is a public project. If you use private projects, you can run up to 1,800 minutes (30 hours) of pipeline jobs for free every month.
Azure DevOps Server
With five or less active users, Azure DevOps Express is free, simple to set up, and installs on both client and server operating systems. It supports all the same features as Azure DevOps Server 2019.
