如何在 docker-compose 中设置主机名? [英] How do I set hostname in docker-compose?

问题描述

在我的 docker-compose.yml 文件中，我有以下内容.但是容器不会获取主机名值.有什么想法吗?

In my docker-compose.yml file, I have the following. However the container does not pick up the hostname value. Any ideas?

dns:
  image: phensley/docker-dns
  hostname: affy
  domainname: affy.com
  volumes:
    - /var/run/docker.sock:/docker.sock

当我检查容器中的主机名时，它没有选择 affy.

When I check the hostname in the container it does not pick up affy.

推荐答案

As of docker-compose 3.0 及更高版本，你可以只使用主机名关键:

As of docker-compose version 3.0 and later, you can just use the hostname key:

version: "3.0"
services:
  dns:
    hostname: your-name
