在docker-compose扩展之后如何通过主机名来访问其他容器？ [英] How to reach additional containers by the hostname after docker-compose scale?

问题描述

我正在使用docker-compose 1.6与docker-compose.yml的docker 1.10.1和version 2。

如在组合中组网，创建新网络，并在 docker-compose up 。

如何在 docker-compose scale< component> = 2 ？

解决方案

根据我看到的示例，假设您的容器名称为 db ，缩放的容器名称为 db_1 ， db_2 等。 。

I'm using the docker-compose 1.6 with docker 1.10.1 and version 2 of docker-compose.yml.

As described in Networking in Compose, new network is created and all containers are assigned hostnames in it after docker-compose up.

How can I reach additional (i.e. scaled) containers via hostnames after docker-compose scale <component>=2?

解决方案

Based on examples I've seen, assuming your container name is db, the scaled containers have the names of db_1, db_2, etc...
