AWS CodePipeline to Deploy Tomcat Application on Amazon EBS

Introduction

This blog explores how to leverage AWS CodePipeline to automate the deployment process of a Tomcat application onto Amazon Elastic Beanstalk.

Use Case

Consider a scenario where a development team manages a web application built on Tomcat. As the application evolves, continuous updates and improvements are necessary. Using AWS CodePipeline, developers can automate the entire deployment process, from source code changes to production deployment on Amazon Elastic Beanstalk. This ensures consistent and reliable application deployment, reducing manual errors and improving time-to-market.

Guide on how to create AWS CodePipeline to deploy Tomcat application on Amazon Elastic Beanstalk

1. Download and install Apache Maven from https://maven.apache.org/download.cgi
2. Add Maven to the environment variables
3. Create an empty directory on your local computer and then run this Maven command

4. Create a subdirectory named .ebextensionsin the ROOT In the .ebextensions subdirectory, create a file named fix-path.config with this content.

container_commands& lastdeploy.log”

fix_path:

command: “unzip ROOT.war 2>&1 > /var/log/my_last_deploy.log”

Once the code has been pushed to GitHub.

Setup a CI/CD Pipeline Using AWS CodePipeline to Deploy a Tomcat Application to AWS Elastic Beanstalk

Follow the below steps:

Type “Elastic Beanstalk” into the search field in the AWS console and select the Elastic Beanstalk service from the search results to navigate to its service page.
Select the “Create Application” button to initiate creating a new application. This action will direct you to a page where you can input the necessary application details.

Please fill in the form with the following values:

Choose a name of your preference.

Under Platform, opt for Node.js, leaving the other settings in the platform section as default.

For the Application Code, choose “Sample application.” Initially, we will deploy a sample application provided by AWS to ensure everything functions as anticipated. Following this, we will integrate CodePipeline and utilize our source code.

Lastly, click the Create Application button.

Click on “Create Pipeline” to initiate the creation of a new pipeline. This action will redirect you to a page where you can input the pipeline details.

Enter a name for the pipeline, such as “ExamplePipeline,” and leave the remaining values in the form as default.

After that, click “Next.”

In the “Add Source Stage,” choose “GitHub (Version 2)” as the Source provider. Then, click “Connect to GitHub” to establish a connection with GitHub.

Next, add the build stage. Select “AWS CodeBuild” as the Build Provider and click “Create project” under the “Project name” section. Enter “ExampleBuild” as the Project name.

In the Environment section, choose the Managed Image managed by AWS CodeBuild. For the Operating system, select Ubuntu using the Standard runtime. Use “aws/codebuild/standard:6.0” for the image.

Then, add environment variables for your application to run the build command.

For the deploy stage, select “AWS Elastic Beanstalk” as the Deploy provider. Choose the Application name and the Environment name (default environment).

Review all settings and click “Create pipeline” when comfortable with the chosen settings.

After the Deploy stage is completed, click the AWS Elastic Beanstalk button within the stage to access the environment. Next, navigate to the environment table and select “Example-env” to view the application.
