Create Your First Pipeline In Azure Devops

In this article, we will create our first pipeline in Azure DevOps.

Purpose

Consider a scenario where a developer is having the code. What are the activities you perform on the code?

You build the code, test the code and deploy the code. The pipeline automates all the processes.

How To Create A Pipeline In Azure Devops?

Before we create the pipeline, we will create a sample .net core application and push it to the repository.

To create the pipeline, click on the "Pipelines" on the left-hand side menu.

A screen appears on the right-hand side. Click on the "Create Pipeline" button.

The first step would be to select the repository type. For this example, I am using the "Azure Repos Git".

Next step is to select the repository.

Once you select a repository, the next step is to select the pipeline.

Once you click on the pipeline, the yaml file will be generated.

Click on the "Save and run" button. A docked window will appear on the right-hand side.

Click on the "Save and run" button. The agent started the process and executes the script mentioned in the yaml file.

YAML File

Here is the yaml file

# ASP.NET Core (.NET Framework)
# Build and test ASP.NET Core projects targeting the full .NET Framework.
# Add steps that publish symbols, save build artifacts, and more:
# https://docs.microsoft.com/azure/devops/pipelines/languages/dotnet-core
trigger:
- master

pool:
  vmImage: windows-latest

variables:
  solution: **/*.sln
  buildPlatform: Any CPU
  buildConfiguration: Release

steps:
- task: NuGetToolInstaller@1

publish NuGet packages
- task: NuGetCommand@2
  inputs:
    restoreSolution: $(solution)

- task: VSBuild@1
  inputs:
    solution: $(solution)
    msbuildArgs: /p:DeployOnBuild=true /p:WebPublishMethod=Package /p:PackageAsSingleFile=true /p:SkipInvalidConfigurations=true /p:DesktopBuildPackageLocation="$(build.artifactStagingDirectory)\WebApp.zip" /p:DeployIisAppPath="Default Web Site"
    platform: $(buildPlatform)
    configuration: $(buildConfiguration)

- task: VSTest@2
  inputs:
    platform: $(buildPlatform)
    configuration: $(buildConfiguration)

Let us discuss each step

Section of YAML	Description
trigger: - master	It means that the agent will execute the process on the master branch.
pool: vmImage: windows-latest	It means that the microsoft agent creates a VM image that contains the latest version of the windows operating system.
variables: solution: */.sln buildPlatform: Any CPU buildConfiguration: Release	This section specifies the solution path, the build platform and the build configuration.
steps: - task: NuGetToolInstaller@1	This task find, download, and cache a specified version of NuGet
- task: NuGetCommand@2 inputs: restoreSolution: $(solution)	This task installs and update NuGet package dependencies, or package and publish NuGet packages
- task: VSBuild@1 inputs: solution: $(solution) msbuildArgs: /p:DeployOnBuild=true /p:WebPublishMethod=Package /p:PackageAsSingleFile=true /p:SkipInvalidConfigurations=true /p:DesktopBuildPackageLocation="$(build.artifa ctStagingDirectory)\WebApp.zip" /p:DeployIisAppPath="Default Web Site" platform: $(buildPlatform) configuration: $(buildConfiguration)	This task build the code with MSBuild
- task: VSTest@2 inputs: platform: $(buildPlatform) configuration: $(buildConfiguration)	This task runs unit and functional tests.
