type
The deployment controller type to use.
There are three deployment controller types available:
ECS
The rolling update (ECS
) deployment type involves replacing the current running version of the container with the latest version. The number of containers Amazon ECS adds or removes from the service during a rolling update is controlled by adjusting the minimum and maximum number of healthy tasks allowed during a service deployment, as specified in the DeploymentConfiguration.
CODE_DEPLOY
The blue/green (CODE_DEPLOY
) deployment type uses the blue/green deployment model powered by CodeDeploy, which allows you to verify a new deployment of a service before sending production traffic to it.
EXTERNAL
The external (EXTERNAL
) deployment type enables you to use any third-party deployment controller for full control over the deployment process for an Amazon ECS service.
