Goal
Running Docker 1.11.2 and docker-compose 1.8.0 (problem persists after downgrading to 1.7.0), I try to update a service in a Docker 1.11.2 Swarm cluster of three nodes. The services in my docker-compose.yml have affinities to ensure that one container of each service is deployed on each node.
The compose-file
services:
service1:
image: myimage1:latest
environment:
- "affinity:com.mycompany.type!=~service1"
- "affinity:container!=~*service1_*"
labels:
- "com.mycompany.type=service1"
service2:
image: myimage2:latest
environment:
- "affinity:com.mycompany.type!=~service2"
- "affinity:container!=~*service2_*"
labels:
- "com.mycompany.type=service2"
Problem
This works well on initial start:
docker-compose -p myproject scale service1=3 service2=3
distributes both services nicely. But when I try to update the project, docker-compose -p myproject up -d places all recreated containers randomly on the nodes, ignoring what I definied as affinities. 
Has anyone a nice idea on how to fix this behavior?
