Docker的MacVLAN方法实现跨主机容器之间的互联

前期准备
主机1：10.10.10.20
主机2：10.10.10.22
下载docker及其依赖
安装Docker的依赖库
yum install -y yum-utils device-mapper-persistent-data lvm2
添加Docker CE的软件源信息
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
安装Docker CE
yum makecache fast
yum -y install docker-ce
启动docker服务
systemctl start docker
主机1：创建maxvlan

[root@base-vm dockerjdk8]#  docker network create --driver macvlan --subnet 10.10.10.0/24 --gatway 10.10.10.254 -o parent=eth0 macvlantest
[root@base-vm dockerjdk8]# docker network ls
NETWORK ID     NAME          DRIVER    SCOPE
5b562dc6924a   bridge        bridge    local
006d4e7bd5e7   host          host      local
d4840d5e6aa7   macvlantest   macvlan   local
c5a276d9a8fd   none          null      local

主机2：创建maxvlan

[root@test ~]# docker network create --driver macvlan --subnet 10.10.10.0/24 --gateway 10.10.10.254 -o parent=ens33 macvlantest
