I have some backup’s of website on my laptop, which I occasionally want to view. Now, I could have setup apache to serve them directly with VirtualHost or alias but wanted a better solution. So, docker comes to rescue.
First, I installed fedora-dockerfiles and then made some modifications, here they are :
sudo yum install fedora-dockerfiles
After this is done, go to /usr/share/fedora-dockerfiles/apache and make some modification to Dockerfile. After the modifications, the file looks like this
