    --     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.
