I got a multi-node docker swarm setup with the following interfaces:

When starting the most simple container stack docker swarm deploy -c simple.yml simple
version: "3.7"
services:
whoami:
image: traefik/whoami
ports:
- 80:80
The container get placed and the service gets bound to 0.0.0.0
. Not exactly ideal.
Better would be for the container to bind to the eth1=10.0.1.2/24
interface. Ideally also lo
- but that would be just the icing on the cake.
What I've tried is to start the docker instances with their respective IPs from the network.
--ip ip Default IP when binding container ports (default 0.0.0.0)
So based on the docs for example: dockerd --ip 10.0.1.2
. Unfortunately that does not seem to change a thing.
I am using Docker version 20.10.4, build d3cb89e
.
Any advise what I might be missing?
