How to Create a Docker Image for Springboot App and Push Docker image into Amazon ECR from Azure DevOps Pipelines | Azure DevOps Pipelines to Build and Push a Docker image to AWS ECR

Amazon Elastic Container Registry (ECR) is a fully managed Docker container registry that makes it easy to store, share, and deploy container images. We will learn how to build docker image for a springboot microservices app using Azure DevOps(ADO) build pipeline and push docker image into AWS ECR.

What are we going to do in this lab?

1. Create a Repository in AWS ECR for storing docker images

2. Create an IAM user and AmazonEC2ContainerRegistryFullAccess policy.

3. Create access keys for IAM user in AWS console

4. Create service connection in AzureDevOps to connect to AWS using IAM user access & secret keys.

5. Create Azure DevOps Build pipeline with below tasks:

• maven build for building JAR
• build docker image
• push docker image into ECR

6. Verify if docker image has been pushed to AWS ECR

Pre-requisites:

• Azure DevOps Account setup and project is created in ADO
• Install AWS toolkit for Azure DevOps
• Setup springboot app in GitHub (you can fork this repository)
• Create service connection in ADO to connect to GitHub personal access Token

Watch Steps in YouTube channel:

Step 1 - Create a repo in ECR 

Go to AWS console, type ECR

Click on Create Repository

Enter name for your repo - all lower case and Click create repository

Create an IAM user

Go to AWS console --> IAM --> Add Users

Enter name for the user

Search for EC2 and choose AmazonEC2ContainerRegistryFullAccess

Click on Create User

Create security credentials

Click on user name ecr-user

Click on Security credentials

Create Access key

Create Service connection 

Go to Project settings --> Service Connections

Enter Access keys and Secret keys

Enter Connect name and select Grant access to all pipelines

Click on save

Create a classic Azure Build pipeline

Click on use the classic editor

Select GitHub and choose your spring-boot project and click continue

Choose a template for the pipeline, type docker and select docker container

Click on Apply

Select build Agent for the Pipeline

Choose Ubuntu latest as build agent

Add Pipeline variables

imageName as springboot-app

repoName as my-springboot-repo

Add Maven task for building springboot JAR file

Make sure Maven task is moved up..it should be a first task

enter maven goas as install

Customize build an image Task 

start customizing the task, choose the version as 2.0

Enter $(imageName) as  Container repository 

Select build as command from drop down

Tags as it have shown below

Remove push an image task

Add ECR push task

now configure the task

Select as shown in screenshot

Choose aws service connection from drop down

select region as per your settings.

select Image ID

enter as $(imageName):$(Build.BuildId)

Repo Name as $(repoName)

$(Build.BuildId) as tar repo tag

Save and Queue

Select ubuntu latest as build agent..do NOT select window agents.

Now make sure build is successful.

Verify if Docker image has been pushed into AWS ECR

Now login to AWS console --> Go to ECR--> select your repo. verify if image has been uploaded successfully.

Please find steps below for integrating SonarQube with Azure DevOps, Previously known as Visual Studio Team Services:

Pre-requisites:

• Make sure SonarQube is up and running
• Make sure Java Project is setup in Azure Repos
• Make sure you install SonarQube plug-in/Add-on in Azure DevOps using below URL:

https://marketplace.visualstudio.com/acquisition?itemName=SonarSource.sonarqube

Once added SonarQube plug-in, click on proceed to Organization..

Watch Steps in YouTube channel:

How to integrate SonarQube with Azure DevOps:

Create Token in SonarQube to authenticate with Azure DevOps

You need to login to SonarQube using your admin password. admin/admin123 and click on Admin on your top side.

Click on My Account, Security. 

Under Tokens, Give some value for token name and choose Global analysis token, click on generate Tokens. Copy the token value generated.

Create Service Connections in Azure DevOps 

Login to Azure DevOps. Select your project dashboard.

Click on Project settings --> Service connections

click on New service connection

Type SonarQube and Click Next

Enter SonarQube server url and enter Token created 

Give name for service connection and select Grant access permission to all pipelines.

Click on Save.

Create a Pipeline in Azure DevOps

1. Login to Azure DevOps. Go to Azure Pipelines. Click on create a new pipeline, use classic editor 

Select your Azure Repos

Type Maven and choose maven template as shown below

2. Click on Add tasks

3. Type Sonar

4. Add Prepare Analysis on SonarQube task
5. move up this task to all the way up.

And also search for Java tool installer task and add it

It should be like shown below:

6. Click on prepare sonar analysis configuration task

select Integrate with Maven or Gradle option

7.Click on Java tool installer and change to 11 instead of 8

8. Edit maven task & add install sonar:sonar and also select the path of pom.xml under MyWebApp/pom.xml

Click on Save and Queue to kick start build.
9. Now login to SonarQube dashboard, click on Projects

How to fix bugs found during SonarQube code analysis | How to resolve defects found in Java Web App during Sonar Scan

Let's say you have configured a build job in Jenkins to implement CI and you are performing code scan using SonarQube. Code scan results shown some defects(bugs) in your Java Code.

If you look at Jenkins console output, you can see analysis was successful.

If you look at SonarQube project dashboard, you are seeing defects like shown below. How do fix those defects? Let's see the steps to fix those defects.

Pre-requisites:

• Sonarqube is setup and running
• Jenkins is up and running
• Java WebApp setup in GitHub
• build job configured in Jenkins to perform code scan

Now login to SonarQube

Click on Project name MyWebApp

Click on Overall code, click on 3 Bugs

Now this shows what is the issue with code. it needs <!DOCTYPE> declaration before <html> tag

Click on Why this an issue to learn more about the issue and how you can fix it.

Now code to GitHub where Java WebApp is configured, edit the index.jsp under MyWebApp/src/main/webapp

Fix for bug # 1

add <!DOCTYPE html> above <html> tag

Fix for bug # 2

add <html lang="en">

Fix for bug # 3

    <head>
          <title>My WebApp</title>
          <meta content="text/html; charset=utf-8" />
    </head>  

Now commit the code changes.

run the build in Jenkins by clicking on Build now.

Login to SonarQube, now you will see no bugs.

This is how you can fix defects found by SonarQube.
