Changing the address for a port mapping doesn't cause the container to be re-created. #1701
Description
Description
It looks like changing the interface where a port is mapped does not count as a difference in the container configuration, so the old container is kept in place.
Steps to reproduce the issue:
Create a docker-compose configuration with a port mapped to all interfaces, then modify the configuration to map the port only on 127.0.0.1.

Describe the results you received:
The container is not recreated and the port stays mapped to the 0.0.0.0 address.
Describe the results you expected:
The container should be recreated with the new port mapping.
Additional information you deem important (e.g. issue happens only occasionally):
Running docker compose down and then docker-compose up -d re-maps the port correctly.
