Virtualmin docker image:

This is still a work in progress (I've only tested this with debian:stretch), you can use the Dockerfile or Docker/Rancher compose (https://github.com/cutech/rOS-catalog/tree/master/templates/Virtualmin).
The Rancher version sets the /home and /usr/share/webmin/virtual-server/scripts/ directories as sidekick volumes for ease in backup and customization of scripts.
You may need to enter the Virtualmin container to start the Virtualmin server and will have to make some changes inside the container (see below)
docker exec -it [container-ID] /bin/bash
[root@CaCrOS rancher]# service webmin start
The docker-compose.yml command should have removed the comments from the /etc/resolv.conf added DNS servers, if not you will have to do it by hand with nano/vi (sed wont do it).
Go to https://your.external.fqdn:10000 and login to the contol panel as root
Right-click on the Webmin tab in the upper left of the control panel and allow webmin popup, reload webmin modules (Checking for usable Webmin modules .. .. found 76 with installed applications, 47 not installed.), reload page, open the servers entry
Go back to the Virtualmin tab and finish the configuation;
Preload Virtualmin libraries? Yes Run email domain lookup server? Yes
Run ClamAV server scanner? No
Run SpamAssassin server filter? No
Run MySQL database server? Yes Run PostgreSQL database server? Yes
PostgreSQL has been enabled, but cannot be used by Virtualmin. Use the PostgreSQL Database module to fix the problem.

x Add a new PostgreSQL user when a Unix user is added.
x Update a PostgreSQL user when the matching Unix user is modified.
x Delete a PostgreSQL user when the matching Unix user is deleted.

Re-check and refresh configuation The Procmail program needed for spam filtering does not appear to be installed on your system, or has not yet been set up properly in Webmin's Procmail Mail Filter module. If your system does not use spam filtering, it should be disabled in Virtualmin's module configuration page. edit /etc/postfix/main.cf, add this line to the end: mailbox_command = /usr/bin/procmail
