Change default subnet for custom docker networks

Our internal network has a range of 172.20.0.0/16 reserved for internal purposes, and docker uses a default range of 172 for its internal network. I can reset the bridge live to 192.168 by providing bip

for the daemon:

➜  ~ sudo cat /etc/docker/daemon.json
{
  "bip": "192.168.2.1/24"
}

➜  ~ ifconfig                        
docker0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
    inet 192.168.2.1  netmask 255.255.255.0  broadcast 0.0.0.0

      

        
        
        
      

    

However, when creating new custom networks through docker network create

or by defining them in sections, networks

docker-compose.yaml

they are still created in 172, which ultimately conflicts with 172.20

:

➜  ~ docker network create foo
610fd0b7ccde621f87d40f8bcbed1699b22788b70a75223264bb14f7e63f5a87
➜  ~ docker network inspect foo | grep Subnet
                "Subnet": "172.17.0.0/16",
➜  ~ docker network create foo1              
d897eab31b2c558517df7fb096fab4af9a4282c286fc9b6bb022be7382d8b4e7
➜  ~ docker network inspect foo1 | grep Subnet
                "Subnet": "172.18.0.0/16",

      

        
        
        
      

    

I understand that I can provide a subnet value docker network create

, but I want all such subnets to be created in 192.168.*

.
