Ec2Service: Cannot attach Ec2Service with NetworkModes HOST or BRIDGE to CloudMap service.

[jamescarter-le]

Describe the bug

I want to attach an EC2Service and container to a CloudMap namespace.

The container is using bridge network mode as it doesn't need special access to the network, and I'm assuming CloudMap can provide my clients with the port resolved by the container, also I want to deploy more containers than I can attach ENIs for on this instance size (so I am not using awsvpc).

I cannot use Service Connect as I do not want to bring this service into my namespace (AWS please let us attach multiple namespaces to services!!)

The bug is that with these network modes, AssociateCloudMapService gives an error.

Expected Behavior

The EC2Service/Container should be attached to the CloudMap service.

Current Behavior

When specifying 'host' or 'bridge' for networkMode, values for 'containerName' and 'containerPort' must be specified from the task definition.

Reproduction Steps

I have the following configuration:

...
PortMappings = new IPortMapping[] { new PortMapping { ContainerPort = 8080, AppProtocol = AppProtocol.Http2, Name = "http" } }
...  
service.AssociateCloudMapService(new AssociateCloudMapServiceOptions
{
    Container = container,
    Service = cloudmapService,
    ContainerPort = 8080,
});

Possible Solution

I'm not sure how it transforms the C# into CDK, but I assume it can pull the container name and port from the referenced container, and attach this?

Unfortunately I can't see how your task definition is defined. Can you share the complete code snippets so we can read more about it?
