Part 1: CI/CD Pipeline Configuration

Create a free account on GitHub and then create a new repository on GitHub called cloudmart

cd challenge-day2/frontend
<Run GitHub steps>

Start by pushing the changes in the CloudMart application source code to GitHub

git status
git add -A
git commit -m "app sent to repo"
git push

Configure AWS CodePipeline

1. Create a New Pipeline:
   • Access AWS CodePipeline.
   • Start the 'Create pipeline' process.
   • Name: cloudmart-cicd-pipeline
   • Use the GitHub repository cloudmart-application as the source.
   • Add the 'cloudmartBuild' project as the build stage.
   • Add the 'cloudmartDeploy' project as the deployment stage.

Configure AWS CodeBuild to Build the Docker Image

1. Create a Build Project:
   • Give the project a name (for example, cloudmartBuild).
   • Connect it to your existing GitHub repository (cloudmart-application).
   • Image: amazonlinux2-x86_64-standard:4.0
   • Configure the environment to support Docker builds. Enable "Enable this flag if you want to build Docker images or want your builds to get elevated privileges"
   • Add the environment variable ECR_REPO with the ECR repository URI.
   • For the build specification, use the following buildspec.yml:

version: 0.2
phases:
  install:
    runtime-versions:
      docker: 20
  pre_build:
    commands:
      - echo Logging in to Amazon ECR...
      - aws --version
      - REPOSITORY_URI=$ECR_REPO
      **- aws ecr-public get-login-password --region us-east-1 | docker login --username AWS --password-stdin public.ecr.aws/l4c0j8h9**
  build:
    commands:
      - echo Build started on `date`
      - echo Building the Docker image...
      - docker build -t $REPOSITORY_URI:latest .
      - docker tag $REPOSITORY_URI:latest $REPOSITORY_URI:$CODEBUILD_RESOLVED_SOURCE_VERSION
  post_build:
    commands:
      - echo Build completed on `date`
      - echo Pushing the Docker image...
      - docker push $REPOSITORY_URI:latest
      - docker push $REPOSITORY_URI:$CODEBUILD_RESOLVED_SOURCE_VERSION
      - export imageTag=$CODEBUILD_RESOLVED_SOURCE_VERSION
      - printf '[{\\"name\\":\\"cloudmart-app\\",\\"imageUri\\":\\"%s\\"}]' $REPOSITORY_URI:$imageTag > imagedefinitions.json
      - cat imagedefinitions.json
      - ls -l

env:
  exported-variables: ["imageTag"]

artifacts:
  files:
    - imagedefinitions.json
    - cloudmart-frontend.yaml

1. Add the AmazonElasticContainerRegistryPublicFullAccess permission to ECR in the service role

• Access the IAM console > Roles.
• Look for the role created "cloudmartBuild" for CodeBuild.
• Add the permission AmazonElasticContainerRegistryPublicFullAccess.

Configure AWS CodeBuild for Application Deployment

Create a Deployment Project:

• Repeat the process of creating projects in CodeBuild.
• Give this project a different name (for example, cloudmartDeployToProduction).
• Configure the environment variables AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY for the credentials of the user eks-user in Cloud Build, so it can authenticate to the Kubernetes cluster.
