…ible-collections#340) ecs_service - support setting deployment controller on a service SUMMARY Support setting platform version to 1.4.0 (LATEST is 1.3.0) and deployment controller. The first allows access to new 1.4.0 features. The second change allows you to create a service that can be controlled with Code Deploy. Example: - name: create a Fargate service community.aws.ecs_service: state: present name: "my-service" cluster: "my-cluster" platform_version: 1.4.0 task_definition: "my-task" desired_count: "1" launch_type: FARGATE scheduling_strategy: REPLICA deployment_controller: type: CODE_DEPLOY load_balancers: - targetGroupArn: "arn:..." containerName: example containerPort: 80 network_configuration: subnets: - "{{vpc_zone_a.subnet.id}}" - "{{vpc_zone_b.subnet.id}}" security_groups: - "sg-example" assign_public_ip: true This fixes ansible-collections#338.
