如何在Docker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。但是，容器不会接收主机名值。任何想法？

  dns：
 image：phensley / docker-dns 
 hostname：affy 
域名：affy.com 
卷：
  -  /var/run/docker.sock:/docker.sock 
  

解决方案

这似乎正常工作。如果我把你的配置文件放到一个文件中：

  $ cat> compose.yml<< EOF 
 dns：
 image：phensley / docker-dns 
主机名：affy 
域名：affy.com 
卷：
  -  /var/run/docker.sock:/docker.sock 
 EOF 
  

然后提起来：

  $ docker-compose -f compose.yml up 
创建tmp_dns_1 ... 
附加到tmp_dns_1 
 dns_1 | 2015-04-28T17：47：45.423387 [dockerdns] table.add tmp_dns_1.docker  - > 172.17.0.5 
  

然后检查容器内的主机名，一切似乎都很好：

  $ docker exec -it stack_dns_1 hostname 
 affy.affy.com 
  

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

解决方案

This seems to work correctly. If I put your config into a file:

$ cat > compose.yml <<EOF
dns:
  image: phensley/docker-dns
  hostname: affy
  domainname: affy.com
  volumes:
    - /var/run/docker.sock:/docker.sock
EOF

And then bring things up:

$ docker-compose -f compose.yml up
Creating tmp_dns_1...
Attaching to tmp_dns_1
dns_1 | 2015-04-28T17:47:45.423387 [dockerdns] table.add tmp_dns_1.docker -> 172.17.0.5

And then check the hostname inside the container, everything seems to be fine:

$ docker exec -it stack_dns_1 hostname
affy.affy.com
