Question

How to configure the default bridge network?

Answer 1

To configure the default bridge network, you need to specify options in daemon.json. 

Here is an example daemon.json with several options specified. Only specify the settings you need to customize.

{
  "bip": "192.168.1.5/24",
  "fixed-cidr": "192.168.1.5/25",
  "fixed-cidr-v6": "2001:db8::/64",
  "mtu": 1500,
  "default-gateway": "10.20.1.1",
  "default-gateway-v6": "2001:db8:abcd::89",
  "dns": ["10.20.1.2","10.20.1.3"]
}

Restart Docker for the changes to take effect.
