AH01114：HTTP：无法建立与后端的连接：localhost（Apache作为Docker容器） [英] AH01114: HTTP: failed to make connection to backend: localhost (apache as docker container)

问题描述

我正在尝试在本地计算机上的服务器应用程序（JIRA）前面设置apache。基于某种程度：
https：// mimiz.github.io/2017/05/18/Configure-docker-httpd-image.html

I am trying to setup apache in front of a server application (JIRA) on my local machine. Somewhat based on: https://mimiz.github.io/2017/05/18/Configure-docker-httpd-image.html

apache和服务器应用程序均作为docker运行

Both apache and the server application are run as docker containers.

启动我的服务器应用程序工作正常，我可以在以下位置访问Web界面：

Starting my server application works fine and I can access the web-ui at:

http://localhost:8087

但是当我开始使用Apache并尝试在我的浏览器中访问它：

But when I start apache and try to access it in my browser:

http://localhost:80

我得到：

Service Unavailable

，当我查看日志时，它说：

and when I look at the logs it says:

H00558: httpd: Could not reliably determine the server's fully qualified domain name, using 172.18.0.5. Set the 'ServerName' directive globally to suppress this message

这是我已启用/添加的 httpd.conf 详细信息：

This is httpd.conf details I have enabled/added:

LoadModule proxy_module modules/mod_proxy.so
#LoadModule proxy_connect_module modules/mod_proxy_connect.so
#LoadModule proxy_ftp_module modules/mod_proxy_ftp.so
LoadModule proxy_http_module modules/mod_proxy_http.so
...

<VirtualHost *:80>
  ServerName www.app1.lol
  ProxyPass / http://localhost:8087
</VirtualHost>

这是我启动服务器应用程序的方式：

And this is how I start my server application:

docker run --network sample-network -p 0.0.0.0:8087:8087 -ti -d --name my-server-container my-server-image

这就是我开始apache的方式：

And this is how I start apache:

docker run -d -p 80:80 --network sample-network --name my-apache-container my-apache-image

我的 httpd.conf 文件或docker run命令（或两者的组合）中的配置是否有问题？

Is the problem my configuration in the httpd.conf file or in the docker run commands (or a combination of both)?

推荐答案

请参考 https://docs.docker.com/network/network-tutorial-standalone/

应进行配置：

<VirtualHost *:80>
  ServerName localhost
  ProxyPass / http://172.17.0.1:8087
</VirtualHost>

或：

<VirtualHost *:80>
      ServerName localhost
      ProxyPass / http://ip_addressof_my-server-container:8087
</VirtualHost>

使用： docker inspect container_id 来查看ip容器的地址。

Use: docker inspect container_id to see ip address of container.
