1.获取帮助
docker network create --help
Usage: docker network create [OPTIONS] NETWORK
Create a network
Options:
--attachable Enable manual container attachment
--aux-address map Auxiliary IPv4 or IPv6 addresses used by Network driver (default map[])
--config-from string The network from which copying the configuration
--config-only Create a configuration only network
-d, --driver string Driver to manage the Network (default "bridge")
--gateway strings IPv4 or IPv6 Gateway for the master subnet
--ingress Create swarm routing-mesh network
--internal Restrict external access to the network
--ip-range strings Allocate container ip from a sub-range
--ipam-driver string IP Address Management Driver (default "default")
--ipam-opt map Set IPAM driver specific options (default map[])
--ipv6 Enable IPv6 networking
--label list Set metadata on a network
-o, --opt map Set driver specific options (default map[])
--scope string Control the network's scope
--subnet strings Subnet in CIDR format that represents a network segment
2.定制bridge方式一【默认Docker0网桥】
网桥一种设备，根据设备的物理地址来划分网段，并传输数据的，docker0就是默认的网桥，如下创建的容器，它们的ip都是从网桥【docker0】自动获取的。
1.创建桥接网络
docker network create --driver [网络类型][网络名称]
#create 创建一个网络
#--driver 指定网络类型
例：
1.创建一个名为bridge-test的bridge网络
docker network create --driver bridge bridge-test
2.查看主机网络类型
docker network ls
3.查看新建网络bridge-test的网络信息
docker network inspect bridge-test

2.自定义网段与网关
docker network create --driver [网络类型] --gateway [网关] --subnet [子网] [网络名称]
#--gateway strings IPv4 or IPv6 Gateway for the master subnet
# 主子网的IPv4或IPv6网关。
#--subnet strings Subnet in CIDR format that represents a network segment
# 表示网络段的CIDR格式的子网。
上述创建桥接网络的时候的网络信息：
docker network inspect bridge-test

例：
1.创建自定义名为bridge-test1的网关为：172.66.0.1，子网为：172.66.0.0/16，bridge模式的网络
docker network create --driver bridge --gateway 172.66.0.1 --subnet 172.66.0.0/16 bridge-test1

3.在自定义网络中启动容器
docker run --net=[网络名称] -itd --name=[容器名称][镜像名称]
在上述创建的两个bridge模式的网络中：
查看容器信息：
docker network inspect bridge-test | grep -Po 'Containers[" :]+\K[^"]+'
docker network inspect bridge-test1 | grep -Po 'Containers[" :]+\K[^"]+'
对应命令：
docker network inspect bridge-test
docker network inspect bridge-test1
中取出json的"Containers"的键对应的值：
bridge-test 和 bridge-test1的容器都是空的。
1.创建启动1个使用网络为【bridge-test1】名为【nginx-wyf-bridge-1】的容器
docker run --net=bridge-test1 -itd --name nginx-wyf-bridge-1 nginx
2.查看运行的容器和容器信息
docker ps

因为没有在bridge-test中启动容器，“Containers”: {},容器依然是空的
docker network inspect bridge-test1

1. 使用默认的桥接模型创建的容器是可以直接联网的。
2. 使用自定义的桥接模型创建的容器不可以直接联网，但是可以通过端口映射来实现联网。
也就意味着：
nginx-wyf-bridge-2和nginx-wyf-bridge-1不能联网， nginx-wyf-bridge-2采用的是自定义的bridge网络bridge-test，nginx-wyf-bridge-1采用的是自定义的bridge网络bridge-test1，所以需要通过端口映射来实现联网。
4.容器断开网络
docker network disconnect [网络名][容器名]
例：
1.断开容器nginx-wyf-bridge-2网络bridge-test
docker network disconnect bridge-test nginx-wyf-bridge-2
2.查看运行的容器
docke ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
57ab1e2a80ed nginx "nginx -g 'daemon of…" 3 minutes ago Up 3 minutes nginx-wyf-bridge-2
2ca0dbed742c nginx "nginx -g 'daemon of…" 9 minutes ago Up 9 minutes 80/tcp nginx-wyf-bridge-1
发现nginx-wyf-bridge-2的网络消失
3.断开容器nginx-wyf-bridge-1网络bridge-test1
docker network disconnect bridge-test1 nginx-wyf-bridge-1
4.查看运行的容器
docke ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
57ab1e2a80ed nginx "nginx -g 'daemon of…" 7 minutes ago Up 7 minutes nginx-wyf-bridge-2
2ca0dbed742c nginx "nginx -g 'daemon of…" 12 minutes ago Up 12 minutes nginx-wyf-bridge-1
发现nginx-wyf-bridge-1的网络也消失了
5.分别查看网络bridge-test bridge-test1的网络
docker network inspect bridge-test | grep -Po 'Containers[" :]+\K[^"]+'
docker network inspect bridge-test1 | grep -Po 'Containers[" :]+\K[^"]+'
发现网络bridge-test、bridge-test1中的容器的信息都没有了
6.分别查看两个容器nginx-wyf-bridge-1、nginx-wyf-bridge-2的信息
docker inspect nginx-wyf-bridge-1
docker inspect nginx-wyf-bridge-2

容器nginx-wyf-bridge-2也有了网络信息
4.查看网络bridge-test和bridge-test1的容器信息
docker network inspect bridge-test
docker network inspect bridge-test1
5.查看容器是否含有对应的网络信息
docker inspect nginx-wyf-bridge-1

3.定制bridge方式二【定制Docker网桥】
网桥一种设备，根据设备的物理地址来划分网段，并传输数据的，docker0就是默认的网桥，如下创建的容器，通过自定义一个br0网桥，然后启动的容器就用自定义的网桥获取。
需求：
定制docker网桥br0
分析：
1、网桥的创建
2、docker服务使用新网桥
3、测试
知识点：
1.bridge-utils软件的brctl工具可以实现创建网桥
2.配置/etc/default/docker文件
3.编辑systemctl的配置文件使用该docker文件
4.重载systemctl配置
5.重启docker
6.创建容器，查看容器信息即可
1.网桥环境部署
1.网桥软件部署
ubuntu默认不自带网桥管理工具，需要自行安装网桥软件
1.安装网桥管理软件
sudo apt install -y bridge-utils
2.查看网卡
brctl show
bridge name bridge id STP enabled interfaces
br-0638f8a6598b 8000.0242da3e7e61 no veth1958f6e
br-2d515e0d7ecd 8000.0242f4770011 no veth7af2da6
docker0 8000.0242331f861f no
| 标题 | 说明 |
|---|---|
| bridge name | 网卡名称 |
| bridge id | 网卡id |
| STP enabled | STP是否启用 |
| interfaces | 物理接口 |
2.创建网桥
1.创建网桥br0
sudo brctl addbr br0
2.查看网卡
brctl show
bridge name bridge id STP enabled interfaces
br-0638f8a6598b 8000.0242da3e7e61 no veth1958f6e
br-2d515e0d7ecd 8000.0242f4770011 no veth7af2da6
br0 8000.000000000000 no
docker0 8000.0242331f861f no
3.设置网桥网段
1.给网桥br0设置网段
网络地址是192.168.66.1，掩码：255.255.255.0
sudo ifconfig br0 192.168.66.1 netmask 255.255.255.0
2.查看网卡信息

2.Docker配置网桥
1.配置docker文件
1.备份源文件
sudo cp /etc/default/docker /etc/default/docker.backup
2.在/etc/default/docker末尾追加DOCKER_OPTS="-b=br0"
sudo sh -c 'echo DOCKER_OPTS=\"-b=br0\" >> /etc/default/docker'
3.确认
cat /etc/default/docker
2.systemctl使用docker文件
1.创建服务依赖文件
创建目录
sudo mkdir -p /etc/systemd/system/docker.service.d
创建文件
sudo vim /etc/systemd/system/docker.service.d/Using_Environment_File.conf
添加内容
[Service]
EnvironmentFile=-/etc/default/docker
ExecStart=
ExecStart=/usr/bin/dockerd -H fd:// $DOCKER_OPTS
2.重载服务配置文件
systemctl daemon-reload
3.重启docker
重启前效果

3.容器测试
1.创建默认网络的容器
docker run -itd --name nginx-wyf-bridge-3 nginx && docker ps
a5142858cd2ebd4b3374c693e74509661f3d7d61c0dbd2e1a1fd5476de3f4383
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
a5142858cd2e nginx "nginx -g 'daemon of…" 1 second ago Up Less than a second 80/tcp nginx-wyf-bridge-3
2.查看容器nginx-wyf-bridge-3详细信息
docker inspect a5142858cd2e
