SELinux causing problems accessing the /opt/xml mount

[ia666]

I ran into an issue where SELinux was blocking access to the /opt/xml mount. The Django app was displaying a debug page because it couldn't open the /opt/xml path.

To get around this problem, you can add the :z flag to the docker run command:

docker run -d --name webmap -h webmap -p 8000:8000 -v /tmp/webmap:/opt/xml:z reborntc/webmap
