Network gateway: Address already in use #8742
Description
Description
Trying to set a gateway to a specific address, but it won't be set.
If I try to set it to 10.10.1.100 the bridge adapter will still be set to 10.10.1.1.
This worked fine in v1, so unless the configuration have changed it could be a bug in v2.
Example:
services:
A:
image: nginx
networks:
mynet:
ipv4_address: '10.10.1.1'
networks:
mynet:
ipam:
config:
- subnet: '10.10.1.0/24'
gateway: '10.10.1.100'eirikb@eh ~/d/t/test> docker network ls
