24-docker 指定容器网络及IP

1.创建网络名为net01,网关是10.1.9.1

[root@docker02 opt]# docker network create -d bridge --subnet 10.1.9.0/24 --gateway 10.1.9.1 net01
53db74e6642a2a0fad3b55ef5c109b79b36a100df733074f300ff222828ec6ea
[root@docker02 opt]# docker network ls
NETWORK ID          NAME                DRIVER              SCOPE
aa53a77695ff        bridge              bridge              local
452e063a1c6f        harbor_harbor       bridge              local
3a821c0610b7        host                host                local
53db74e6642a        net01               bridge              local
18f030428279        none                null                local

 2.创建一个容器1，指定IP是10.1.9.100，网络是net01

[root@docker02 opt]# docker run -it --rm --network=net01 --ip 10.1.9.100 busybox
/ # 
/ # ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
166: eth0@if167: <BROADCAST,MULTICAST,UP,LOWER_UP,M-DOWN> mtu 1500 qdisc noqueue 
    link/ether 02:42:0a:01:09:64 brd ff:ff:ff:ff:ff:ff
    inet 10.1.9.100/24 brd 10.1.9.255 scope global eth0
       valid_lft forever preferred_lft forever

  3.创建一个容器1，指定IP是10.1.9.101，网络是net01

[root@docker02 ~]# docker run -it --rm --network=net01 --ip 10.1.9.101 busybox
/ # ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
177: eth0@if178: <BROADCAST,MULTICAST,UP,LOWER_UP,M-DOWN> mtu 1500 qdisc noqueue 
    link/ether 02:42:0a:01:09:65 brd ff:ff:ff:ff:ff:ff
    inet 10.1.9.101/24 brd 10.1.9.255 scope global eth0
       valid_lft forever preferred_lft forever

 4.测试自定义网络的IP连通性

/ # ping 10.1.9.100
PING 10.1.9.100 (10.1.9.100): 56 data bytes
64 bytes from 10.1.9.100: seq=0 ttl=64 time=0.141 ms
64 bytes from 10.1.9.100: seq=1 ttl=64 time=0.064 ms
64 bytes from 10.1.9.100: seq=2 ttl=64 time=0.174 ms
64 bytes from 10.1.9.100: seq=3 ttl=64 time=0.069 ms
64 bytes from 10.1.9.100: seq=4 ttl=64 time=0.070 ms
64 bytes from 10.1.9.100: seq=5 ttl=64 time=0.064 ms

 5.查看net01网络信息

[root@docker02 opt]# docker network inspect net01
[
    {
        "Name": "net01",
        "Id": "412877924ea50a7e2838930b040ebd19f75e8808cba5220df03f23b8e9fa2ba0",

                    "Gateway": "10.1.9.1"
                }
            ]
        },
        "Internal": false,
        "Attachable": false,
        "Ingress": false,
        "ConfigFrom": {
            "Network": ""
        },

                "IPv4Address": "10.1.9.101/24",

            }
        },
        "Options": {},
        "Labels": {}
    }
]
