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

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.
