如何让/ etc / profile在Alpine / Docker中自动运行 [英] How to get /etc/profile to run automatically in Alpine / Docker

问题描述

如何以交互方式启动Alpine Docker容器时，如何获得 / etc / profile 自动运行？我已经将一些别名添加到 aliases.sh 文件中，并将其放在 /etc/profile.d 中，但是我使用 docker run -it [my_container] sh 启动容器，我的别名不活动。我必须手动输入。 / etc / profile 从命令行每次。

是否有一些其他配置需要获得 / etc /个人资料在登录时运行？我也遇到使用〜/ .profile 文件的问题。任何见解都是感激的！

编辑：

根据VonC的答案，我拉扯了他的例子 ruby​​ container。这是我得到的：

  $ docker run --rm --name ruby​​ -it codeclimate / alpine-ruby：b42 
 /＃more /etc/profile.d/rubygems.sh 
 export PATH = $ PATH：/usr/lib/ruby/gems/2.0.0/bin 
 /＃env 
 no_proxy = *。local，169.254 / 16 
 HOSTNAME = 6c7e93ebc5a1 
 SHLVL = 1 
 HOME = / root 
 TERM = xterm 
 PATH = / usr / local / sbin：/ usr / local / bin：/ usr / sbin：/ usr / bin：/ sbin：/ bin 
 PWD = / 
 /＃exit 
  / pre> 
 
 
尽管 /etc/profile.d/rubygems.sh 文件存在，但没有运行当我登录时，我的 PATH 环境变量没有被更新。我使用错误的 docker运行命令？还有别的东西吗有没有人在Docker上与Alpine搭配使用〜/ .profile 或 /etc/profile.d / 谢谢！
解决方案
你还可以尝试在Dockerfile中a：
  RUN echo'\ 
。 / etc / profile; \ 
'>> /root/.profile 
  
（假设当前用户是根如果没有，请用完整的首页路径替换 / root  
 
 
 
就是说，那些应该运行/etc/profile.d/xx.sh。
 
请参阅  codeclimate / docker-alpine-ruby  为例：
  COPY文件/ 
  
使用' 文件/ etc  包括一个  files / etc / profile。 d / ruby​​gems.sh  运行正常。
 
 
 
 
 
 
在 OP工程   Dockerfile  ，有一个
  COPY aliases.sh /etc/profile.d/ 
  
但是默认shell是不是登录shell（sh -l），这意味着 个人资料文件（或 /etc/profile.d 中的文件）是不来源
 
 
 
添加 sh -l <​​/ code>将工作：
  docker @ default：〜$ docker run --rm --name ruby​​ -it codeclimate / alpine-ruby：b42 sh -l 
 87a58e26b744：/＃echo $ PATH 
 /usr/local/sbin:/usr/local/bin//usr/sbin:/usr/bin:/sbin:/bin:/usr/lib/ruby/gems/2.0.0/bin 
  
 
How can I get /etc/profile to run automatically when starting an Alpine Docker container interactively? I have added some aliases to an aliases.sh file and placed it in /etc/profile.d, but when I start the container using docker run -it [my_container] sh, my aliases aren't active. I have to manually type . /etc/profile from the command line each time.


Is there some other configuration necessary to get /etc/profile to run at login? I've also had problems with using a ~/.profile file. Any insight is appreciated!

EDIT:

Based on VonC's answer, I pulled and ran his example ruby container. Here is what I got:
$ docker run --rm --name ruby -it codeclimate/alpine-ruby:b42
/ # more /etc/profile.d/rubygems.sh
export PATH=$PATH:/usr/lib/ruby/gems/2.0.0/bin
/ # env
no_proxy=*.local, 169.254/16
HOSTNAME=6c7e93ebc5a1
SHLVL=1
HOME=/root
TERM=xterm
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
PWD=/
/ # exit
Although the /etc/profile.d/rubygems.sh file exists, it is not being run when I login and my PATH environment variable is not being updated. Am I using the wrong docker run command? Is something else missing? Has anyone gotten ~/.profile or /etc/profile.d/ files to work with Alpine on Docker? Thanks!
解决方案
You still can try in your Dockerfile a:
RUN echo '\
        . /etc/profile ; \
    ' >> /root/.profile
(assuming the current user is root. If not, replace /root with the full home path)

That being said, those /etc/profile.d/xx.sh should run.

See codeclimate/docker-alpine-ruby as an example:
COPY files /
With 'files/etc" including an files/etc/profile.d/rubygems.sh running just fine.



In the OP project Dockerfile, there is a 
COPY aliases.sh /etc/profile.d/
But the default shell is not a login shell (sh -l), which means profile files (or those in /etc/profile.d) are not sourced.

Adding sh -l would work:
docker@default:~$ docker run --rm --name ruby -it codeclimate/alpine-ruby:b42 sh -l
87a58e26b744:/# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/lib/ruby/gems/2.0.0/bin
