AWS Beanstalk sample application steps

1. Java installation

   a) Install java

    https://openjdk.org/install/
   

   b) Verify java installation

    java --version
   

2. Create the source code

3. Download and install Maven.

   a) Download and install Maven

    https://maven.apache.org/download.cgi
   

   b) Extract tar file

       tar -xvf apache-maven-3.6.3-bin.tar.gz
       export M2_HOME="/Users/pankaj/Downloads/apache-maven-3.6.3"
       PATH="${M2_HOME}/bin:${PATH}"
       export PATH
       mvn -version
   

4. Switch to an empty directory on your local computer or instance, and then run this Maven command.

   mvn archetype:generate "-DgroupId=com.mycompany.app" "-DartifactId=ROOT" "-DarchetypeArtifactId=maven-archetype-webapp" "-DinteractiveMode=false"
   

5. Create a subdirectory named .ebextensions in the ROOT directory. n the .ebextensions subdirectory, create a file named fix-path.config with this content

   container_commands:
     fix_path:
       command: "unzip ROOT.war 2>&1 > /var/log/my_last_deploy.log"
   

Scenario B: Use CodePipeline to run CodeBuild and deploy to Elastic Beanstalk

In this scenario, you complete the steps to prepare and upload the source code. You create a build project with CodeBuild and an Elastic Beanstalk application and environment with the AWS Elastic Beanstalk console. You then use the AWS CodePipeline console to create a pipeline. After you create the pipeline, CodePipeline builds the source code and deploys the build output to the environment.

Step b1: Add a buildspec file to the source code

In this step, you create and add a buildspec file to the code you created in Create the source code. You then upload the source code to an S3 input bucket or a CodeCommit, GitHub, or Bitbucket repository.

a) Create a file named buildspec.yml with the following contents. Store the file in the ROOT directory.

version: 0.2             
phases:
  install:
    runtime-versions:
      java: corretto11
  post_build:
    commands:
      - mvn package
      - mv target/ROOT.war ROOT.war
artifacts:
  files:
    - ROOT.war
    - .ebextensions/**/*

b) Your file structure should now look like this.

        └── ROOT
            ├── .ebextensions
            │   └── fix-path.config
            ├── src
            │   └── main
            │       ├── resources
            │       └── webapp
            │           ├── WEB-INF
            │           │   └── web.xml
            │           └── index.jsp
            ├── buildpsec.yml
            └── pom.xml

c) Upload the contents of the ROOT directory to GitHub (not root dir itself).

Step b2: Create a build project

In this step, you create an AWS CodeBuild build project to use with your pipeline.

1. Open the AWS CodeBuild console at https://console.aws.amazon.com/codesuite/codebuild/home.

2. Create a build project : For more information, see Create a build project (console) and Run a build (console). Leave all settings at their default values, except for these settings.

   For Environment:

   For Environment image, choose Managed image.
   For Operating system, choose Amazon Linux 2.
   For Runtime(s), choose Standard.
   For Image, choose aws/codebuild/amazonlinux2-x86_64-standard:3.0.
   

   For Artifacts:

   For Type, choose Amazon S3.
   For Bucket name, enter the name of an S3 bucket.
   For Name, enter a build output file name that's easy for you to remember. Include the .zip extension.
   For Artifacts packaging, choose Zip.
   

Step b3: Create an Elastic Beanstalk application and environment

In this step, you create an Elastic Beanstalk application and environment to use with CodePipeline.

1) Open the Elastic Beanstalk console at https://docs.aws.amazon.com/codebuild/latest/userguide/sample-elastic-beanstalk.html#sample-elastic-beanstalk-codepipeline

Step b4: Create the pipeline and deploy

In this step, you use the AWS CodePipeline console to create a pipeline. After you create and run the pipeline, CodePipeline uses CodeBuild to build the source code. CodePipeline then uses Elastic Beanstalk to deploy the build output to the environment.

1) Create or identify a service role that CodePipeline, CodeBuild, and Elastic Beanstalk can use to access resources on your behalf. For more information, see Prerequisites.

2) Open the CodePipeline console at https://console.aws.amazon.com/codesuite/codepipeline/home.

    Use the AWS Region selector to choose an AWS Region where CodeBuild is supported. If you're storing the source code in an S3 input bucket, the output bucket must be in the same AWS region as the input bucket.

3) Create a pipeline. For information, see Create a pipeline that uses CodeBuild (CodePipeline console). Leave all settings at their default values, except for these settings.

    On Add build stage, for Build provider, choose AWS CodeBuild. For Project name, choose the build project you just created.

    On Add deploy stage, for Deploy provider, choose AWS Elastic Beanstalk.

        For Application name, choose the Elastic Beanstalk application you just created.

        For Environment name, choose the environment you just created.
