1、修改docker0网段

1. 修改配置文件daemon.json

{
  "data-root": "/opt/docker",
  "bip":"192.166.0.1/24",##新增bip
  "insecure-registries": [
    "http://10.168.1.137:5000"
  ]
}

2. 重启docker

systemctl restart docker

2、修改docker_gwbridge网段

1. 删除docker_gwbridge

删除之前需要将容器都停掉，不然无法删除，因为有容器在使用网络

容器停掉之后，进行删除,执行命令：docker network rm docker_gwbridge

你会发现依然报错说有节点在使用，用下面命令查看谁在使用docker_gwbridge

docker network inspect docker_gwbridge

 "ingress-sbox": {
                "Name": "gateway_ingress-sbox",
                "EndpointID": "1c9df24ee07bebde7c0b2529aa36c281d08b8d368a50e6ccaa1e55e5df3b5aa0",
                "MacAddress": "02:42:c0:a7:00:02",
                "IPv4Address": "192.167.0.2/16",
                "IPv6Address": ""
            }

找到之后将其断开连接：docker network disconnect -f docker_gwbridge gateway_ingress-sbox

然后再次执行删除命令就可以删除了： docker network rm docker_gwbridge

2. 新建docker_gwbridge

docker network create \
--subnet 192.169.0.0/16 \
--gateway 192.169.0.1 \
--opt com.docker.network.bridge.name=docker_gwbridge \
--opt com.docker.network.bridge.enable_icc=false \
--opt com.docker.network.bridge.enable_ip_masquerade=true \
docker_gwbridge

3. 重启docker

systemctl restart docker
