I can specify the container port with `service_port` but it always maps it to a (random?) port on the host. Is there a way to specify both container port _and_ host port? Thanks ---

Based on the [reviewing the Docker Platform plugin code](https://github.com/hashicorp/waypoint/blob/main/builtin/docker/platform.go#L167), it looks like the host ports are not configurable. What scenario have you encountered where it is ideal to be able to set the host port? Something like having a predictable port for a load balancer pointing at the docker host? ---

I’m deploying a container to a remote instance that has Docker running, the host port is fixed (no load balancer yet, but the port is whitelisted). This seems pretty common to me, I wonder if there’s any workaround. ---

Yes, there may be a work-around until the Docker plugin makes it possible to specify this option. For now you could use the `exec` plugin as demonstrated in the [`kubectl apply` example](https://github.com/hashicorp/waypoint-examples/tree/main/kubernetes/exec-kubectl-apply) but reference a script template that executes `docker run` with the parameters you want instead. I don’t believe there would be a way to dynamically set the port easily with `waypoint.hcl`, but you can set it explicitly in the templated file. ---

Thanks @jbayer, a few open questions on this: 1. is what I’m trying to achieve that weird? seems like a really common case to me, deploying to a remote docker host where you need to know on which port your app runs. 2. if the answer is “yes”, what would be an alternative to this? using kubernetes? ---

No, what you’re asking about is not strange, the Docker plug-in is incomplete currently. If you used Kubernetes, it would require you to hook up whatever ingress solution you are using (eg a load balancer) to the k8s service associated with the app. ---

In my case, I need to expose 2 ports, one for the service and one for remote debugging. Is there any workaround for that?
