Cannot route to registered services by name

Docker Desktop for Windows
1

I love 1.12 so far :heart_eyes: but I’m having trouble accessing services by their name. I’m hoping I’m just doing something wrong. This may not be a Windows specific issue, and just a misunderstanding in how to configure swarm mode networking.

Expected behavior

Creating a docker service named ‘pending’ on port 3000 should allow me to navigate/ping ‘pending:3000’

Actual behavior

Service cannot be reached

Steps to reproduce the behavior

1.) Clone https://github.com/AndrewBell/wet-tech
2.) $ docker compose build
3.) $ docker swarm init
4.) $ docker service create --replicas 1 --name pending recursivechaos/pending-service

I’ve also tried to configure docker networking as following, but without luck.

3.5) $ docker network create -d overlay mynet
4.) $ docker service create --replicas 1 --name pending --publish 3000:3000/tcp --network mynet recursivechaos/pending-service

I’m fairly certain this isn’t an issue with Docker for Windows at this point, but rather Docker network configuration. I don’t know if I can delete/move this question, but I’ve created a new one in the Swarm category: How to configure Swarm Service Discovery (1.12)
