Blue Green ECS Service with custom CloudFormation

Why custom ECS Service

AWS ECS Service supports three types of Deployment Controller(For More Details):

• ECS (default)
• CODE_DEPLOY(blue/green)
• EXTERNAL

  We can set CODE_DEPLOY as deployment controller and achieve BLUE/GREEN deployment of the ECS Service unfortunately there is no support to manipulate DeploymentController properties through Cloudformation. You should either use API/CLI or build your own custom cloudformation.

Creating Custom BG ECS service

export SAM_SOURCE_BUCKET=<your-sam-bucket>
export STACK_NAME=<your-stack-name>
cd create-ecs-service
make package
make deploy

Why custom deployment group

AWS CloudFormation Doesn’t have native support for the ECS type Blue/Green DeploymentGroup.

Creating Custom BG CodeDeploy Deployment Group
