Build pipeline basics in Azure - Mini Project: Build & Apply

Build pipeline basics

📖 Scenario: You are working on a software project and want to automate the process of building your code whenever you make changes. This helps catch errors early and saves time.We will create a simple build pipeline configuration file that defines the steps to build your project automatically.

🎯 Goal: Build a basic Azure DevOps pipeline YAML file that defines a trigger, a pool, and a build step to compile your code.

📋 What You'll Learn

Create a YAML file named azure-pipelines.yml

Define a trigger on the main branch

Specify the build agent pool as ubuntu-latest

Add a build step to run a shell command echo Building project...

💡 Why This Matters

🌍 Real World

Automating builds saves time and reduces errors by running builds automatically when code changes.

💼 Career

Understanding build pipelines is essential for DevOps roles to ensure continuous integration and delivery.

1

Create the pipeline trigger

Create a YAML file named azure-pipelines.yml and add a trigger section that triggers the pipeline on the main branch only. Write exactly trigger: followed by - main on the next line.

Azure

# Your code here

Need a hint?

The trigger section tells Azure DevOps which branches to watch for changes.

2

Add the build agent pool

Below the trigger section, add a pool section with vmImage: 'ubuntu-latest' to specify the build agent. Use exactly pool: and vmImage: 'ubuntu-latest' with correct indentation.

Azure

trigger:
- main
# Your code here

Need a hint?

The pool section tells Azure DevOps which machine image to use for running the build.

3

Add a build step

Add a steps section below pool. Inside steps, add a script step that runs the shell command echo Building project.... Use exactly - script: echo Building project... with correct indentation.

Azure

trigger:
- main

pool:
  vmImage: 'ubuntu-latest'
# Your code here

Need a hint?

The steps section defines the commands to run during the build.

4

Display the complete pipeline

Print the complete contents of the azure-pipelines.yml file to verify your pipeline configuration.

Azure

trigger:
- main

pool:
  vmImage: 'ubuntu-latest'

steps:
- script: echo Building project...
# Your code here

Need a hint?

Use a print statement to show the full YAML content exactly as written.
