Docker 集装箱ifconfig&；NSIPS don'；不匹配
我正在运行一个名为“前端”的容器。其他容器通过使用名称前端与该容器通信，该名称解析为容器IP地址。我注意到这个容器有点不合我的意思 当我将shell放入容器并运行“ifconfig”时，我看到一个IP地址。当我运行“nslookup front-end”时，我看到另一个IP地址。我想这两个IP应该是匹配的。请参见下面的“我的终端输出”： 我在群集模式下做这件事。以下是我如何启动容器：Docker 集装箱ifconfig&；NSIPS don'；不匹配,docker,Docker,我正在运行一个名为“前端”的容器。其他容器通过使用名称前端与该容器通信，该名称解析为容器IP地址。我注意到这个容器有点不合我的意思 当我将shell放入容器并运行“ifconfig”时，我看到一个IP地址。当我运行“nslookup front-end”时，我看到另一个IP地址。我想这两个IP应该是匹配的。请参见下面的“我的终端输出”： 我在群集模式下做这件事。以下是我如何启动容器： docker service create --with-registry-auth --name first

- 您可以在撰写文件中命名服务
redis service - 您可以通过redis服务连接到该redis服务器
- 如果将此redis服务复制到五个实例，那么应该解析哪个ip地址
将解析为一个虚拟ip，五个redis实例将通过该虚拟ip进行负载平衡redis服务- 即使只有一个实例也是一样的
