 Implications Setting Launch Type
 
-Since it can be reasonably assumed that any CapacityProvideStrategies defined on the Service are what the customer intends to use on the Service, the LaunchType will *not* be set on the Service if CapacityProvideStrategies are specified. This is similar to how the LaunchType field is unset if the service uses an external DeploymentController (https://github.com/aws/aws-cdk/blob/master/packages/%40aws-cdk/aws-ecs/lib/base/base-service.ts#L374).

 On the other hand, this intent would not be as obvious with Default Capacity Provider Strategies defined a cluster. A *defaultCapacityProviderStrategy* specified on a cluster is used for any service that does not specify either a launchType or its own CapacityProviderStrategies. From the point of view of the ECS APIs, similar to how custom CapacityProvideStrategies defined on the Service are expected to supersede the defaultCapacityProviderStrategy on a cluster, the expected behavior for an ECS Service that specifies a launchType is for it to also ignore the Cluster’s defaultCapacityProviderStrategy.
 
-However, since the two Service constructs in the CDK (Ec2Service and FargateService) do not support having the launchType field passed in explicitly, it would not possible to infer whether the intent of the customer using one of these Service constructs is to use the implied launchType (currently set under the hood in the service’s constructor (https://github.com/aws/aws-cdk/blob/master/packages/%40aws-cdk/aws-ecs/lib/fargate/fargate-service.ts#L155)) or the defaultCapacityProviderStrategy.  For this reason, we will not be adding the  defaultCapacityProviderStrategy field on the Cluster construct for this iteration.

For this reason, we will not be adding the  defaultCapacityProviderStrategy field on the Cluster construct for this iteration.
 
 _*Note*_: Future for support will be dependent on a re-design of the existing Service strategies. This will be treated in v2 of the ECS modules, likely with a single Service L2 construct and deprecation of the Ec2Service and FargateService constructs.

 To address issue [#1698](https://github.com/aws/aws-cdk/issues/1698), the ECS construct library should provide a way for customers to specify [`repositoryCredentials`](https://docs.aws.amazon.com/AmazonECS/latest/APIReference/API_ContainerDefinition.html#ECS-Type-ContainerDefinition-repositoryCredentials) on their container.
 
-Minimally, this would mean adding a new string field on `ContainerDefinition`, however this doesn't provide any added value in terms of logical grouping or resource creation. We can instead modify the existing ECS CDK construct [`ContainerImage`](https://github.com/aws/aws-cdk/blob/master/packages/%40aws-cdk/aws-ecs/lib/container-image.ts) so that repository credentials are specified along with the image they're meant to access.
