Docker type of network

4 network type:

None: No container configured to any network function, - net = none
Container: Network Namespace shared with another operation in the container, - net = Container: containerID (K8S)
the Host: Network Namespace shared with the host, - net Host =
Bridge: NAT network model Docker design

The following are explained below:

none：

[root@docker1 centos_zabbix]# docker run -it --network none centos6.9_ssh:v2 /bin/bash
[root@6ae597015723 /]# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1
    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

　　This is not ip, you can easily play in the container, there is not much sense

container types of networks:

[root@docker1 centos_zabbix]# docker inspect 41c457f6b89d|grep -i network
            "NetworkMode": "container:1c21de6080bb8c83e800fa8b5fb15782a18bb61ab292050ca1172fbb866b1afc",
        "NetworkSettings": {
            "Networks": {}

　Note that this type of public container port with a port is who, who accounted for, the later can not use this port

host type

[root@docker1 centos_zabbix]# docker run -it --network=host centos6.9_nginx_ssh:v2 /bin/bash

　　This is the common port and the host, who should occupy who use, but the highest performance, so we use this parameter when building the image, is to unify the type of network, improve the efficiency of building Mirror
