 ```
-docker run --name cups -p 631:631   --restart unless-stopped  \
+docker run --name cups --restart unless-stopped  --net host\

-## Install Avahi on local host:
-These commands only work on RedHat/CentOS/Fedora. Ubuntu will be different.
-```
-yum install avahi
-systemctl start avahi-daemon
-systemctl enable avahi-daemon
-```
-***This was the only way I was able to get /var/run/dbus to respond correctly in the container.***

 ## Add and set up printer:
 CUPS will be configurable at http://[host ip]:631 using the CUPSADMIN/CUPSPASSWORD.
