title: How to install apache module in docker container at the correct location
body: <p>I have the following docker file:</p>
  
  <pre><code>FROM wodby/apache:2.4
  MAINTAINER NAME EMAIL
  ENV http_proxy 'http://xxx.xxx.xxx.de:80'
  ENV https_proxy 'http://xxx.xxx.xxx.xxx:80'
  ENV APP_ROOT="/var/www/html" \
      APACHE_DIR="/usr/local/apache2"
  
  WORKDIR /usr/local/apache2
  
  USER root
  RUN ls
  
  
  RUN set -x \
      &amp;&amp; apk add apache-mod-auth-kerb
  
  
  CMD ["tail", "-f", "/dev/null"]
  </code></pre>
  
  <p>My intention is to add the apache-mod-auth-kerb module to my container.<br>
  Base Image is alpine but wodby/apache inherits from wodby/http which is Debian.  </p>
  
  <p>Somehow the module is installed under /usr/lib/apache2 but the apache in wodby/apache seems to load its modules from /usr/local/apache2/modules.</p>
  
  <p>I don't think the solution is to move the module per cp or symlink?</p>
  
  <p>Here are the links to the base dockerfiles:
  <a href="https://github.com/wodby/httpd" rel="nofollow noreferrer">https://github.com/wodby/httpd</a>
  <a href="https://github.com/wodby/apache" rel="nofollow noreferrer">https://github.com/wodby/apache</a></p>
  
  <p>How can I make sure that the module and config are put in the correct location? I think the problem might be the difference between the used Linux distros. 
  Any hints?</p>
