interface ens33是固定写法吗？

Question

老师您好：我的服务器现在启了两个keepalived节点 但是我其中一个用interface ens33配置信息 keepalived启动不起来 我就都改成了interface eth0 其中的不同的地方是：
virtual_ipaddress {
172.19.0.100
}
virtual_ipaddress {
172.19.0.101
}
我的服务器我执行 ip address命令如下

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

h2容器里面的网卡也叫做eth0，没有不一样

Answer 2

eth0是docker容器的网卡，只有在docker容器里面才能看到这个网卡。ens33是虚拟机的网卡

• 提问者 周鸣 #1

  那是所有的docker容器都公用这个网卡是吗？还是不同的容器都会有一个网卡。还有我看你您给我的资料里 h1的配置中 interface  ens33是这个配置项目。h1为什么跟h2的配置不一样呢

  所有的docker容器网卡都叫做eth0
