Less nutty than you might think, it’s one cam per kerberos instance, just the way they build the tool. So if you want multiple cams, just start multiple containers, it’s pretty easy at that.
Mine are running from user ‘cam’ (which is in the docker system group) and all configs and what not are stored per camera.
cam="cam2"
docker run -d \
--name ${cam} \
-p 82:80 -p 8882:8882 \
-v /home/cam/config/${cam}/web/config:/var/www/web/config/ \
-v /home/cam/config/${cam}/config:/etc/opt/kerberosio/config \
-v /home/cam/config/${cam}/logs:/etc/opt/kerberosio/logs \
-v /home/cam/nfs/cam/${cam}:/etc/opt/kerberosio/capture \
