Docker CentOS图像不会自动启动httpd [英] Docker CentOS image does not auto start httpd

问题描述

我试图用Apache和PHP程序来运行一个简单的Docker映像。如果我运行

  docker运行-t -i -p 80:80我/ httpd / bin / bash 
  

然后手动启动Apache

 code> service httpd start 
  

但是，我无法让httpd在运行时自动启动

  docker run -d -p 80:80 my / httpd 
  

Apache将启动然后容器存在。我已经在我的码头文件中尝试了一堆不同的 CMD

  CMD /etc/init.d/httpd start 
 CMD [servicehttpdstart] 
 CMD [/ bin / bash，/etc/init.d/httpd start ] 
 ENTRYPOINT /etc/init.d/httpd CMD start 
 CMD ./start.sh 
  

start.sh是

 ＃！/ bin / bash 
 /etc/init.d/ httpd start 
  

但是，apache启动后，每个停泊点的实例都将存在

我缺少一些非常明显的东西？

解决方案

你需要直接运行apache（httpd）不应该使用init.d脚本。

两个选项：

1. 你必须在前台运行apache： / usr / sbin / apache2 -DFOREGROUND ... （或CentOS中的/ usr / sbin / httpd）


2. 您必须启动所有服务（包括配置为自动运行的apache）通过执行 / sbin / init 作为入口点。

I'm trying to run a simple Docker image with Apache and a PHP program. It works fine if I run

docker run -t -i -p 80:80 my/httpd /bin/bash

then manually start Apache

service httpd start

however I cant get httpd to start automatically when running

docker run -d -p 80:80 my/httpd

Apache will startup then container exists. I have tried a bunch of different CMDs in my docker file

CMD /etc/init.d/httpd start
CMD ["service" "httpd" "start"]
CMD ["/bin/bash", "/etc/init.d/httpd start"]
ENTRYPOINT /etc/init.d/httpd CMD start
CMD ./start.sh

start.sh is

#!/bin/bash
/etc/init.d/httpd start

However every-time docker instance will exist after apache starts

Am I missing something really obvious?

解决方案

You need to run apache (httpd) directly - you should not use init.d script.

Two options:

1. you have to run apache in foreground: /usr/sbin/apache2 -DFOREGROUND ... (or /usr/sbin/httpd in CentOS)
2. you have to start all services (including apache configured as auto-run) by executing /sbin/init as entrypoint.
