Migrating Jenkinsfiles to AzDO

Published: Jul 22, 2021 by Isaac Johnson

Jenkins as a Continuous Integration tool is one of the longest active (if considering it’s existence as Hudson) and commands a considerable market share. As such, in considering migrating from Jenkins to Azure DevOps, we may have to consider dealing with a large amount of current Jenkinsfile projects upon which our users actively rely.

While In the long run, we will likely want to rewrite them to use native Azure DevOps yaml tasks, templates, variables and agent pools. In the short term, we can use a simple method to run them inline in Azure DevOps with JenkinsFile Runner.

Running Locally

We can first try this on a local WSL instance or ubuntu host.

The first thing we will do is get jenkinsfile-runner:

builder@DESKTOP-JBA79RT:~/Workspaces/jfRunnerDemo$ wget https://github.com/jenkinsci/jenkinsfile-runner/releases/download/1.0-beta-29/jenkinsfile-runner-1.0-beta-29.zip
Will not apply HSTS. The HSTS database must be a regular and non-world-writable file.
ERROR: could not open HSTS store at '/home/builder/.wget-hsts'. HSTS will be disabled.

We can start with a simple helloworld pipeline:

$ cat helloworld/jenkinsfile
pipeline {
    agent any
    stages {
        stage('Print hello') {
            steps {
                echo 'Hello world!'
            }
        }
    }
}

Running with CLI

We can make a jenkinsfile and run it, but will find lots of errors due to missing plugins:

$ ./bin/jenkinsfile-runner -f ./helloworld/jenkinsfile

You can try and fill the plugins folder manually and run things:

The reason is that the docker image itself maps just a plugins dir , not file. So it makes it rather hard to mimic the CLI unless we wish to rebuild the container

Rebuilding the Container

We’ll pull from the jenkins-file runner GH repo: https://github.com/jenkinsci/jenkinsfile-runner/

$ git clone https://github.com/jenkinsci/jenkinsfile-runner.git

$ cd jenkinsfile-runner

Next we will build the container as it stands

Here is thelauncher file and we can see the “–plugins” hard codes a dir

Let’s change the runner to handle a created plugins.txt file

Setting up an AzDO Pipeline

Let’s create a simple example:

azure-pipelines.yml

# JF Runner
 
trigger:
- main
 
pr:
- main
 
pool:
  vmImage: 'ubuntu-latest'
 
stages:
- stage: RunAsBinary
  displayName: Running JFRunner binary
  jobs:
  - job: JFRunner
    steps:
    - script: |
        wget https://github.com/jenkinsci/jenkinsfile-runner/releases/download/1.0-beta-29/jenkinsfile-runner-1.0-beta-29.zip
        unzip jenkinsfile-runner-1.0-beta-29.zip
        chmod u+x ./bin/jenkinsfile-runner
      displayName: 'get JFR binary'
 
    - script: |
        ./bin/jenkinsfile-runner -p ./helloworld/plugins.txt -f ./helloworld/jenkinsfile
      displayName: 'Run JFRunner'

Then we can set up our jenkinsfile and plugins in a helloworld subfolder

$ cat ./helloworld/jenkinsfilepipeline {
    agent any
    stages {
        stage('Print hello') {
            steps {
                echo 'Hello world!'
            }
        }
    }

Saving and adding the YAML pipeline shows it works just fine

Docker Agent based Jenkinsfile Builds in AzDO:

These work just as well

An updated Jenkinsfile:

pipeline {
    agent { docker { image 'maven:3.3.3' } }
    stages {
        stage('build') {
            steps {
                sh 'mvn --version'
            }
        }
    }
}

and see it works just fine

While it did take 4 minutes to pull down a fresh Maven image and run, it still showed we could use a specified containerized agent inline. From the log pictured above:

Summary

We asked the simple question: How can we quickly build existing Jenkins projects using Azure DevOps with minimal modification?

By using jenkinsfile-runner and a well populated plugins list, we can easily run both containerized agent and non containerized agent jenkinsfile builds with ease.

This method can be a quick Phase 0 win for any group working to help migrate existing users out of the older Jenkins product into something like Azure DevOps as part of a larger overall migration journey.
