Switch smoothly between CodeDeploy deployment group compute platform:

ECS fargate launch type Blue/Green
ECS EC2 launch type Blue/Green
ASG
EC2 instance

Architecture

Prerequisites

Two AWS accounts, each has a IAM user

Dev account ID: 111111111111
The IAM user has AdministratorAccess policy, Access key & Secret access key, and HTTPS Git credentials for CodeCommit
Prod account ID: 222222222222
The IAM user has AdministratorAccess policy, Access key & Secret access key

Installation Instructions

1. ECS fargate Blue/Green deployment group
2. ECS EC2 Blue/Green deployment group
3. ASG deployment group
4. EC2 deployment group

1. Create ECS fargate launch type Blue/Green deployment group, and CI/CD CodePipeline

1.1 Launch EC2 instance as config host in both `Dev&Prod` accounts, clone github repository respectively

    git clone https://github.com/dragonflly/pipeline-cicd.git

Repository folder tree:

  └── pipeline-cicd
      ├── application
      │   ├── ec2-asg-httpd
      │   ├── ecs-ec2-httpd
      │   └── ecs-fargate-httpd
      ├── cfn-template
      ├── CLI-json
      ├── iam-resource
      ├── images
      └── README.md

1.2 Create CFN template S3 Bucket in `Dev&Prod` accounts, and upload CFN templates

Create S3 bucket (Example: templates-dev-us-east-1 in us-east-1) in Dev account

    aws s3api create-bucket --bucket templates-dev-us-east-1 --region us-east-1

Upload folder pipeline-cicd to bucket templates-dev-us-east-1

    aws s3 cp pipeline-cicd s3://templates-dev-us-east-1/pipeline-cicd --recursive

Create S3 bucket (Example: templates-prod-us-east-1 in us-east-1) in Prod account

    aws s3api create-bucket --bucket templates-prod-us-east-1 --region us-east-1

Upload folder pipeline-cicd to bucket templates-prod-us-east-1

    aws s3 cp pipeline-cicd s3://templates-prod-us-east-1/pipeline-cicd --recursive

1.3 Create ECR repository, and push docker image to the ECR repository in `Dev account`

Create ECR repository (Example: apache-server-repo in us-east-1)

    aws ecr create-repository --repository-name apache-server-repo --region us-east-1

Change directory to pipeline-cicd/application/ecs-fargate-httpd, build docker image

    cd pipeline-cicd/application/ecs-fargate-httpd

          ]
        }
      ]
    }

1.4 Create ECS fargate launch type Blue/Green deployment group in `Prod account`
