Implementing CI/CD in Mule Using Jenkins

Author: Kishan Jasani

Introduction

CI/CD is a method to frequently deliver apps to customers by introducing automation into the stages of app development. The main concepts attributed to CI/CD are continuous integration, continuous delivery, and continuous deployment. CI/CD is a solution to the problems integrating new code can cause for development and operations.

Specifically, CI/CD introduces ongoing automation and continuous monitoring throughout the lifecycle of apps, from integration and testing phases to delivery and deployment. Taken together, these connected practices are often referred to as a “CI/CD pipeline.” They are supported by development and operations teams working together in an agile way with a DevOps approach.

Prerequisites

Anypoint Platform setup

• Navigate to https://anypoint.mulesoft.com
• Check your Anypoint credentials ( username and password) and Deployment environment
• Github setup

• Navigate to your GitHub account https://github.com
• Check your GitHub credentials ( username and password) and Login
• Create a Repository and Push your code
• Save git repository URL Where you want to implement CI/CD pipeline (https://github.com/Kishan-Jasani/bookmyholiday-ws.git)

• Jenkins setup
•  Download Jenkins from https://www.jenkins.io/download/

•  Unzip the executable jar and host the application on port 8080

•  Navigate to http://localhost:8080/ and setup admin username and password

• Project level configuration
• Open pom.xml of your mule project

• Find <plugin> tag under <plugins> where <groupId> is equal to org.mule.tools.maven

<plugin>     <groupId>org.mule.tools.maven</groupId>     <artifactId>mule-maven-plugin</artifactId>     <version>${mule.maven.plugin.version}</version>     <extensions>true</extensions> </plugin>

• Add <configuration> tag inside <plugin>

<plugin>     <groupId>org.mule.tools.maven</groupId>     <artifactId>mule-maven-plugin</artifactId>     <version>${mule.maven.plugin.version}</version>     <extensions>true</extensions>     <configuration>         <cloudHubDeployment>             <uri>https://anypoint.mulesoft.com</uri>             <muleVersion>${mule.version}</muleVersion>             <username>${anypoint.username}</username>             <password>${anypoint.password}</password>             <environment>${env}</environment>             <applicationName>${appname}</applicationName>             <businessGroup>${business}</businessGroup>             <workerType>${vCore}</workerType>             <workers>${workers}</workers>             <objectStoreV2>true</objectStoreV2>         </cloudHubDeployment>     </configuration> </plugin>

• Setting up CI CD Pipeline using Jenkins
• Navigate to http://localhost:8080/ and login with admin username and password

• Click on Manage Jenkins     →           Manage Credentials

• Under Stores scoped to Jenkins on the right, click on Jenkins

• Under System, click the Global credentials (unrestricted) link to access this default domain.

• Click Add Credentials on the left.

• Enter your Github Username and Password and click on OK

• Navigate to http://localhost:8080/ and click on New Item
• Enter an item name, select Free Style Project and click on OK

• You will be navigated to the configuration page
• Enter Pipeline Description and GitHub Project url where you want to implement CI CD pipeline

• Scroll down to Source Code Management and select git.
• Add Repository URL and select credential from drop down

• Specify branch of your repository where you want to set up your CI CD pipeline

• Under Build Triggers, click on Poll SCM and write cron expressions as per your requirement. 

(For example, write ‘* * * * *’ ,If you want to check the update on repository every minute)

• Under Build, Add build step ‘Invoke top-level Maven targets’

• Select Maven Version as ‘MAVEN_HOME’ and write Goals

(You Copy and Paste Goals from below)

• Goals:-

clean deploy -DmuleDeploy -DskipTests -Dmule.version=4.3.0 -Danypoint.username=<Your Anypoint Platform Username> -Danypoint.password=<Your Anypoint Platform Password> -Denv=<Your Anypoint Platform Environmanet> -Dappname=cicd-pipeline-demo -Dbusiness=Apisero -DvCore=Micro -Dworkers=1

• Click on Apply
• Click on Save
• You will be redirected to Dashboard. Build will start automatically every time you change your code in the GitHub repository.

• Your Pipeline will start running. You can see the Console Output

• Your Project will start deploying automatically in your Anypoint Platform

• We are now ready with our CI CD pipeline
