我正在阅读 this官方 Docker 0.10.3 文档(此时,它还在一个分支中)并且它说:
--net-alias=ALIAS
In addition to --name as described above, a container is discovered by one or more of its configured --net-alias (or --alias in docker network connect command) within the user-defined network. The embedded DNS server maintains the mapping between all of the container aliases and its IP address on a specific user-defined network. A container can have different aliases in different networks by using the --alias option in docker network connect command.
--link=CONTAINER_NAME:ALIAS
Using this option as you run a container gives the embedded DNS an extra entry named ALIAS that points to the IP address of the container identified by CONTAINER_NAME. When using --link the embedded DNS will guarantee that localized lookup result only on that container where the --link is used. This lets processes inside the new container connect to container without without having to know its name or IP.
--net-alias
之间有两个区别和 --link
:
--net-alias
,一个容器只有在同一个网络上才能访问另一个容器。也就是说,除了--net-alias foo
和 --net-alias bar
,您需要使用 --net foobar_net
启动两个容器使用 docker network create foobar_net
创建网络后. --net-alias foo
, 全部 同一网络中的容器可以通过别名foo
访问容器。 .与 --link
, 只有链接的容器 可以使用名称 foo
访问容器. --link
之前创建的 libnetwork
以及所有与网络相关的功能。之前 libnetwork
,所有容器都在同一网络中运行 bridge
, 和 --link
仅将名称添加到 /etc/hosts
.然后,添加了自定义网络和 the behavior of --link
in user-defined networks was changed .--link
的更多信息.
