Docker之容器连接到指定网络

#### 1.创建网络bridge ####

(1) 创建新的网络 为lss-net

docker network create -d bridge lss-net

\-d 后面第一个bridge是网络的连接方式

(2) 查看当前的网络列表

docker network ls

查看bridge列表

brctl show

##### 2. 创建容器test3,连接到网络lss-net中 #####

(1)创建容器

docker run -d --name test3 --network my-bridge busybox /bin/sh -c "while true ;do sleep 3600;done"

(2) 查看网络 lss-net 的连接情况

[root@localhost ~]# docker network inspect lss-net
    [
        {
            "Name": "lss-net",
            "Id": "f0626cf13f9abe0bae5c741befc06df47a2bc5093e13ae5d1e94be8b85e57ae9",
            "Created": "2019-03-01T10:20:10.254037204+08:00",
            "Scope": "local",
            "Driver": "bridge",
            "EnableIPv6": false,
            "IPAM": {
                "Driver": "default",
                "Options": {},
                "Config": [
                    {
                        "Subnet": "172.19.0.0/16",
                        "Gateway": "172.19.0.1"
                    }
                ]
            },
            "Internal": false,
            "Attachable": false,
            "Ingress": false,
            "ConfigFrom": {
                "Network": ""
            },
            "ConfigOnly": false,
            "Containers": {
                "ceb07ba99ff7ac35bf4d7ecbafeae5963906383b763b91120f76e73479bb97b5": {
                    "Name": "test3",
                    "EndpointID": "2602f2d752de46c8a2c6b01829e291b2395d18c4163da6d52702630ab8c029fd",
                    "MacAddress": "02:42:ac:13:00:02",
                    "IPv4Address": "172.19.0.2/16",
                    "IPv6Address": ""
                }
            },
            "Options": {},
            "Labels": {}
        }
    ]

发现该网络已连接到容器test3中

##### 3. 手动将指定网络与指定容器连接 #####

(1)操作指令为:

docker network connect [网络] [容器]

(2) 下面将容器test2也连接到网络 lss-net中

docker network connect lss-net test2

(3) 此时再次查看 网络lss-net的连接情况,发现test2和test3都在其中

> docker network inspect lss-net

"Containers": {
                "89a8286ce291b63105bb08c78ff8aa3dab99c50765c421b3ea92cebd97b63174": {
                    "Name": "test2",
                    "EndpointID": "bca33cb77116a1bd9814ff42ae378bdb06a0079c198ac764b826d5efc894da5b",
                    "MacAddress": "02:42:ac:13:00:03",
                    "IPv4Address": "172.19.0.3/16",
                    "IPv6Address": ""
                },
                "ceb07ba99ff7ac35bf4d7ecbafeae5963906383b763b91120f76e73479bb97b5": {
                    "Name": "test3",
                    "EndpointID": "2602f2d752de46c8a2c6b01829e291b2395d18c4163da6d52702630ab8c029fd",
                    "MacAddress": "02:42:ac:13:00:02",
                    "IPv4Address": "172.19.0.2/16",
                    "IPv6Address": ""
                }
            },

此时,test2与test3都是可以ping通的.

（注意是自己创建的网络，不是系统自己默认的网络）,这样双方都可以通过名字互ping上)
