====== LXC containers ======
The current defined containers are listed here. Note that the actual active container for visionlab website is **visielab-test**

To do some testing on the visielab website, just make a snapshot, and then copy the snapshot. Then you can experiment on that copy after starting it. For example, visielab-test is currently the active visielab website. To test some special stuff on that website, we do the following.

===== networking of the LXC containers =====
We defined all networking in /etc/lxd_bridge.conf .To use dnsmasq with this data, the correct variable must be defined in /etc/default/lxd-bridge -> LXD_CONFILE="/etc/lxd_bridge.conf"

<code>
cat lxd_bridge.conf 
domain=ac.ua.be
dhcp-host=nextcloud,10.27.117.84
dhcp-host=openaudit,10.27.117.9
dhcp-host=visielab,10.27.117.144
dhcp-host=visielab-test,10.27.117.155
dhcp-host=visielab-test2,10.27.117.250
dhcp-host=visielab-wiki,10.27.117.55
</code>

===== reverse proxying via apache =====
to address the different websites in the lxc containers, we use reverse proxying with apache2.
