一、Docker网络的管理

博彩app大全:1、Docker容器的方式

1)Docker访问外网

Docker容器连接到宿主机的Docker0网桥访问外网;默认自动将docker0网桥添加到docker容器中。

2)容器和容器之间通信

需要管理员创建网桥;将不同的容器连接到网桥上实现容器和容器之间相互访问。

3)外部网络访问容器

通过端口映射或者同步docker宿主机网络配置实现通信。

2、Docker容器网络通信的模式

1)bridge

默认容器访问外网通信使用;依赖docker0网桥。

2)none

需要给容器创建独立的网络命名空间;不会给创建的容器配置TCP/IP信息。

3)container

容器和容器通信使用;容器需要共享容器名称空间,博彩app大全:通过共享容器名称空间实现不同容器通信。

4)host

容器内部网络和宿主机保持同步。

3、配置bridge网络通信模式

[root@centos01 yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://www.4468844.com/879/repo/Centos-7.repo

6、配置docker0网卡参数

[root@centos01 ~]# ifconfig    <!--查看docker宿主机IP地址-->
docker0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 172.17.0.1  netmask 255.255.0.0  broadcast 0.0.0.0
[root@centos01 ~]# systemctl stop docker   <!--停止docker服务-->
[root@centos01 ~]# ip link set dev docker0 down   <!--停止docker0网桥-->
[root@centos01 ~]# brctl delbr docker0    <!--删除系统默认的docker0网桥-->
[root@centos01 ~]# brctl addbr docker0   <!--创建新的网桥,名字是docker0-->
[root@centos01 ~]# ip addr add 192.168.20.1/24 dev dokcer0  <!--新的网桥docker0配置IP地址-->
[root@centos01 ~]# ip link set dev docker0 up   <!--启动新的docker0网桥-->
[root@centos01 ~]# vim /etc/docker/daemon.json    
       <!--修改docker配置文件加载新的网桥docker0-->
{"registry-mirrors":["http://www.ib911.com/981"]}
{"bip":"192.168.20.1/24"}    <!--加此行-->
[root@centos01 ~]# systemctl start docker   <!--启动docker服务-->
[root@centos01 ~]# ifconfig    <!--查看docker宿主机IP详细信息-->
docker0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.20.1  netmask 255.255.255.0  broadcast 0.0.0.0
[root@centos01 ~]# docker run -it -d --name centos7.2v1 hub.c.163.com/public/centos:7.2-tools    <!--创建一个容器在后台运行-->
d0b5392e60cef37f3c44d79a9fb73916720cfc44faa7b73862bee05fb2d6ce7b
[root@centos01 ~]# docker exec -it centos7.2v1 /bin/bash  <!--登录centos7.2v1容器-->
[root@d0b5392e60ce /]# ifconfig    <!--查看IP地址详细信息-->
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.20.2  netmask 255.255.255.0  broadcast 0.0.0.0

二、Docker网络隔离

1、Docker网络隔离原理

需要管理创建网络空间名称;将不同的容器加载到不同的网络空间名称中实现隔离;默认不配置网络隔离默认给容器分配的docker0网络空间名称。

2、Docker容器自带的网络空间名称类型

bridge:容器桥接到docker0网桥上;

host:容器同步docker宿主机的网络配置信息;

none:不创建网络,docker容器不需要配置TCP/IP信息;

3、配置Docker网络名称空间隔离

[root@centos01 ~]# docker network ls   <!--查看docker默认的网络名称空间-->
NETWORK ID          NAME                DRIVER              SCOPE
8bb953004416        bridge              bridge              local
2c18234cad82        host                host                local
67860e823c36        none                null                local
[root@centos01 ~]# docker network create -d bridge liyanxin  <!--创建网络名称空间-->
0c69de4672ec173dc4c60b19e0bf93b361f45a804859f7bc2105d85ca83b1169
[root@centos01 ~]# docker network create -d bridge gongsunli   <!--创建网络名称空间-->

        inet 172.18.0.1  netmask 255.255.0.0  broadcast 0.0.0.0

br-35687468c903: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        inet 172.19.0.1  netmask 255.255.0.0  broadcast 0.0.0.0
[root@centos01 ~]# docker run -it -d --name centos6.701 --network=liyanxin hub.c.163.com/public/centos:6.7-tools    
         <!--创建运行的容器添加到liyanxin网络名称空间中隔离-->

三、配置网桥实现网络隔离

1、配置网桥实现网络隔离的目的

实现Docker宿主机的容器跨Docker宿主机的容器通信使用。

2、配置网桥实现网络隔离原理

将物理网卡桥接到创建的网桥网卡上;给网桥网卡配置IP地址;创建容器加载网桥网卡实现;docker宿主机容器跨docker宿主机容器通信;管理员管理docker宿主机通过网桥网卡进行远程管理

3、配置docker网桥实现网络隔离

[root@centos01 ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens32  
         <!--修改docker宿主机物理网卡桥接到网桥网卡br0-->
TYPE=Ethernet
PROXY_METHOD=none

[root@centos01 ~]# cp /etc/sysconfig/network-scripts/ifcfg-ens32 /etc/sysconfig/network-scripts/ifcfg-br0   
         <!--创建并生成br0网桥-->
[root@centos01 ~]# vim /etc/sysconfig/network-scripts/ifcfg-br0 <!--编辑br0网卡配置文件-->
