Description
When deploying 2 different services that create two default overlay networks the pools overlap.

Reproduce
docker stack deploy -c docker-compose.yml hello
docker-compose.yml
version: '3.9'
services:
helloworld:
# This will set the hostname to helloworld-ReplicaID
hostname: "helloworld-{{.Task.Slot}}"
# The image, we will use a helloworld http image
image: strm/helloworld-http
# We will expose the service at port 8080 on the host
ports:
- "8080:80"
# Docker Swarm configuration deployment configurations!
deploy:
# We want to replicate our service...
mode: replicated
# And it will have two instances of the container!
replicas: 2
docker stack deploy -c docker-compose2.yml hello2
docker-compose2.yml
version: '3.9'
services:
helloworld:
# This will set the hostname to helloworld-ReplicaID
hostname: "helloworld-{{.Task.Slot}}"
