Beginner’s Handbook for Implementing Azure DevOps Pipelines

Imagine you want to put your code on the cloud. You try, but you keep having trouble. Many beginners have problems with team setups. Pipelines can be slow. Error reports can be hard to read. Some common problems are:

• Environments do not match. This makes code break.

• Teams use old tools. Some teams work alone.

• There are security risks. Reports are hard to understand.

You can use Azure DevOps Pipelines to automate steps. This helps you avoid these problems. You follow easy steps. You save time and make your work simple.

Key Takeaways

• Azure DevOps Pipelines help teams work faster. They build, test, and deploy code by themselves. This helps teams find mistakes early. It also lets teams send updates quickly.

• You can make pipelines in two ways. Use Classic, which is a visual editor. Or use YAML, which is a code file. Pick the way that works best for your team. Think about your team's skills and needs.

• Connect your pipeline to your code repository. You can use GitHub or Azure Repos. When you push changes, the pipeline runs automatically.

• Add automated tests to your pipeline. Use deployment strategies like rolling or canary. These steps make your code better and lower risks.

• Follow best practices to keep pipelines safe. Secure secrets and use templates. Run jobs at the same time and watch logs. This helps pipelines work well and stay safe.

Azure DevOps Pipelines Setup

What Are Pipelines?

Azure DevOps Pipelines help you build, test, and send out your code. Pipelines link to your code in places like GitHub or Azure Repos. When you change your code, the pipeline starts by itself. It builds your app, checks for problems, and sends updates to the cloud or other spots. This way, you can find mistakes early and send updates faster. You can use pipelines for web, mobile, or desktop apps. Pipelines also show you dashboards and reports so you can see how things are going.

Tip: Pipelines help your team work together. You spot problems fast and fix them before users see them.

Prerequisites

Before you set up Azure DevOps Pipelines, you need a few things:

1. You need an Azure DevOps account.

2. You must have a code repository, like GitHub, Azure Repos, or BitBucket.

3. Your computer should use a supported operating system, like Windows 10 or Windows Server 2012 or newer.

4. PowerShell 3.0 or higher must be on your computer.

5. If you use Subversion, you need to install the Subversion client.

6. Visual Studio build tools (2015 or newer) help you build code.

7. You need permission to make and manage pipelines and service connections.

8. Keep your agent folders safe to protect secrets and logs.

Note: It is smart to use a different account for agents. This keeps your system safe.

Account and Project

First, sign up for Azure DevOps. If you do not have a Microsoft or GitHub account, make one. Go to Azure DevOps and log in. The system will make an organization for you. On your homepage, click "New Project". Type a name and pick if it is public or private. Choose your version control, like Git or TFVC. Click "Create" to finish. Now, you can invite your team, set up code, and start using Azure DevOps Pipelines.

Here is a quick guide:

1. Sign in to Azure DevOps.
2. Create an organization.
3. Click 'New Project'.
4. Enter project name and set visibility.
5. Choose version control (Git or TFVC).
6. Click 'Create'.
7. Invite your team and start working.

You now have a place for your code, tasks, and pipelines. This makes teamwork and automation simple.

Creating Pipelines

When you use Azure DevOps Pipelines, you pick from two types. These are Classic and YAML. Each type is good for different needs. You should choose the one that matches your project and team.

Classic Pipeline

Classic pipelines use a visual tool. You do not need to write code. You can drag tasks to build your pipeline. This is good if you are new to automation. You can see each step as you build.

To make a Classic pipeline, follow these steps:

1. Open your Azure DevOps project and go to "Pipelines."

2. Click "Create Pipeline."

3. Pick your code source, like Azure Repos Git or GitHub.

4. Click "Use the classic editor."

5. Choose your repository, project, and branch.

6. Click "Continue."

7. Pick a template or start with an empty job.

8. Give your pipeline a name, like "PipelineDemo-CICD."

9. Pick the agent pool and agent type, such as "windows-latest."

10. Add tasks, like building or testing code.

11. Save and queue the pipeline to run it.

Tip: Classic pipelines let you add approvals and gates. You can also see and fix each step.

Classic pipelines are good for beginners. You can set up builds fast and see results quickly.

YAML Pipeline

YAML pipelines use a code file for steps. You write instructions in a file called azure-pipelines.yml. This file is in your code repository. YAML pipelines help teams work together. You can track changes and use pull requests.

To make a YAML pipeline, do these steps:

1. In your Azure DevOps project, go to "Pipelines" and click "Create Pipeline."

2. Pick your code source, like GitHub or Azure Repos.

3. Choose the repository and branch.

4. Pick "YAML" as the pipeline type.

5. Azure DevOps gives you a starter YAML file. You can change this file or write your own.

6. Save the azure-pipelines.yml file in your repository. You can put it at the root or in a folder.

7. Write pipeline stages, jobs, and steps in the YAML file. For example:

trigger:
  - main

pool:
  vmImage: 'ubuntu-latest'

steps:
  - script: echo Hello, world!
    displayName: 'Run a one-line script'

1. Save and run the pipeline. Azure DevOps will follow the steps in your YAML file.

Note: You can have more than one YAML file in your repo. This helps if you need different pipelines for different projects.

YAML pipelines are good for teamwork. You can review changes and keep a history. This works well for big teams or if you want more control.

Classic vs. YAML Pipelines

Here is a table to help you compare Classic and YAML pipelines:

Classic pipelines are easy and quick to use. YAML pipelines give you more power and better teamwork.

Source Control Integration

You need to link your pipeline to your code. Azure DevOps Pipelines work with GitHub, Azure Repos, and more. Linking your source control lets the pipeline run when you push new code.

To connect to GitHub or Azure Repos, do these steps:

1. In Azure DevOps, go to Project Settings and find "GitHub Connections."

2. Make a new connection by signing into GitHub and allowing access.

3. Pick the repositories you want to link.

4. Go to "Pipelines" and create a new pipeline. Choose GitHub or Azure Repos as the source.

5. Pick your repository and set up your pipeline steps.

6. Save and run the pipeline. Now, every time you push code, the pipeline will start.

Always use service connections to keep your credentials safe. Only give permissions you need.

You can use things like multi-repo checkout and submodules. This helps if your project uses more than one repository.

The azure-pipelines.yml file sets up your pipeline. You can put it anywhere in your repository. When you set up the pipeline, you tell Azure DevOps where to find the file. This lets you have different pipelines for different builds or projects.

Tip: Store secrets and tokens in Azure DevOps, not in your code. This keeps your project safe.

Azure DevOps Pipelines make it easy to automate builds and deployments. You can connect to your code, set up steps, and let the system do the work.

Build, Test, Deploy

Build Steps

First, you set up build steps in your pipeline. These steps tell the system how to put your code together. They also get it ready for testing or sending out. You can use agents for Windows, Linux, or macOS. Pick the agent pool and choose the agent type, like ubuntu-latest for Linux. You can make variables in your YAML file to change settings. Use $(variableName) to use them. You can run jobs at the same time with the strategy keyword. Use matrix or parallel options for this. This helps you build faster and try different settings together.

Tip: Share variables across jobs with variable groups and templates. This makes your pipeline easier to handle.

• You can set rules for when steps should run.

• Workspace folders like Build.SourcesDirectory help keep files neat for each agent job.

• You can build web, desktop, or mobile apps.

Automated Tests

You add automated tests to your pipeline to find mistakes in your code. Azure DevOps Pipelines work with many test types and frameworks. Here is a table that shows some choices:

You can run unit, integration, UI, and performance tests. To add tests, do these steps:

1. Make sure your agent is working.

2. Clean your project to get rid of old files.

3. Build and run your tests.

4. Share test results with tasks like PublishTestResults.

5. See reports in the Azure DevOps portal.

Note: You can set triggers so tests run every time you push new code.

Deployment

You send out your app after building and testing. Azure DevOps Pipelines let you pick how you want to deploy:

You can send your app to Windows, Linux, virtual machines, containers, or serverless platforms. Pick the best agent and place for your app. You can run deployments at the same time to save time.

• Azure App Service helps with web apps on Windows and Linux.

• Azure Kubernetes Service lets you send containers.

• Azure Functions work for serverless apps.

You can control deployments with special hooks for testing and undoing changes.

Best Practices and Troubleshooting

Azure DevOps Pipelines Best Practices

You can make your pipelines better by following some simple steps. First, set branch protection rules and ask for more than one reviewer. This keeps your code safe and good. Use linting tools to check your code style. Break your pipeline into smaller parts with templates and variable groups. This helps you use the same steps again and keeps things neat. Set up different settings for each environment with variable groups and conditions. Make builds faster by running jobs at the same time and using caching. Add strong error handling, logging, and notifications so you know when something is wrong. Use continuous integration to run builds and tests every time you push code. Add code quality checks with tools like SonarQube to find bugs early. Manage your dependencies and artifacts with Azure Artifacts. Try advanced deployment methods like blue-green or canary releases to lower risk. Always plan for rollbacks and watch your deployments after release.

Templates and modularization help keep your pipelines clear and easy to change. You can use the same steps in many projects and update them in one place.

Security Tips

You need to keep your secrets safe and control who can use your pipelines. Here are some tips to help you. Store secrets in Azure Key Vault and link them to your pipelines. Do not put secrets in your code or pipeline files. Mark variables as secret so they stay hidden in logs. Use managed identities or workload identity federation for authentication instead of passwords. Limit service connections to only the resources they need. Give users the least amount of access needed for their work. Turn on auditing to track changes and spot problems. Change credentials often and scan for secrets in your code. Use branch policies and require approvals for changes to pipelines or secrets. Hide secrets in logs and do not print them in scripts. Use tools like Microsoft Defender for DevOps to scan for problems.

Always check who can use your pipelines and secrets. Remove accounts you do not use and check logs for strange activity.

Common Issues

You might see some common problems when using Azure DevOps Pipelines. Here are some and how to fix them. Missing PowerShell modules can make builds fail. Make sure all needed modules are installed. Script path errors happen if the path is wrong. Double-check your file paths. 403 Forbidden errors mean you do not have enough permissions. Check your service connections and user rights. No output from scripts can happen if the task is set up wrong. Review your task settings. Merge conflicts happen when two people change the same file. Fix these conflicts on your computer before pushing. Pipeline runs may fail if agents are offline or busy. Check agent status and add more agents if needed. Sometimes, your pipeline waits for manual approval. Make sure you approve steps when needed.

If a pipeline fails, look at the logs for details. Turn on verbose logging for more information. Download logs if you need to share them with your team.

You can also add extensions from the Azure DevOps Marketplace. These give you new tasks, widgets, or security tools. They help you find issues faster and add new features to your pipelines.
