1、查看本地路由

pc:~$ ip route 查看本地路由，确认冲突网络

172.25.0.0/16 dev br-ce9d5ebabd41 proto kernel scope link src 172.25.0.1
172.26.0.0/16 dev br-ec81b8882e8d proto kernel scope link src 172.26.0.1 linkdown
172.29.0.0/16 dev br-f7ceae3419bb proto kernel scope link src 172.29.0.1
192.168.0.0/20 dev br-11ea30af8617 proto kernel scope link src 192.168.0.1
192.168.16.0/20 dev br-33f008111edb proto kernel scope link src 192.168.16.1 linkdown
192.168.192.0/24 dev eno1 proto kernel scope link src 192.168.192.100

查看 br-11ea30af8617网卡详细信息，确认容器名称

-pc:~$ docker inspect 11ea30af8617

确认容器

pc:~$ docker ps |grep server-1003

方法一、

1、删除容器
-pc:~$ docker rm -f 容器ID

2、删除容器网卡
-pc:-$ docker network rm 网卡ID

方法二、

创建容器网卡，配置子网(遵循最小网段)

docker network create --driver bridge --subnet=192.168.1.0/24 --gateway=192.168.1.1 my_network

例如:

sudo docker network create  --driver bridge --subnet=192.168.100.0/24 --gateway=192.168.100.1 network-local d69df2a7987940774ab60922c9441c8356945645108e429b065ce19961b3abb9

查看容器网络

sudo docker network ls

NETWORK ID NAME DRIVER SCOPE

edce8d89b518 bridge bridge local

26b2915f3907 host host local

d69df2a79879 network-local bridge local

49fe4ba65ea4 none null local

查看新建网卡信息

test@host112:~$ sudo docker inspect nginx-local|grep Network

        "NetworkMode": "bridge",
    "NetworkSettings": {
        "Networks": {
                "NetworkID": "edce8d89b518d8f462ad0e0baa6e4fcdcf341753d081c1e1e2a3b3c313456bf2",

将容器加入到新网络

test@host112:~$ sudo docker network connect network-local nginx-local
查看容器现有网络
test@host112:~$ sudo docker inspect nginx-local|grep Network

“NetworkMode”: “bridge”,
“NetworkSettings”: {
“Networks”: {
“NetworkID”: “edce8d89b518d8f462ad0e0baa6e4fcdcf341753d081c1e1e2a3b3c313456bf2”,
“NetworkID”: “d69df2a7987940774ab60922c9441c8356945645108e429b065ce19961b3abb9”,

将容器从网络中移除

test@host112:~$ sudo docker network disconnect bridge nginx-local
查看容器现有网络
test@host112:~$ sudo docker inspect nginx-local|grep Network

        "NetworkMode": "bridge",
    "NetworkSettings": {
        "Networks": {
                "NetworkID": "d69df2a7987940774ab60922c9441c8356945645108e429b065ce19961b3abb9",
