I've been building rocket.chat contribs but a recent update to a node module broke stuff, probably for good on v9.
I had a play using docker, and following the work by HSF to flesh out some templates I have made a little contrib to automate the basic configs.
The rpm is in my repo 'reetp' and called smeserver-docker
It includes docker-compose.
Base dir for stuff is in /home/e-smith/files/docker which would then be included in backups if required.
I'll add some stuff to the wiki when I get a minute.
See my git repo for a few notes.
For testing on a test vm only please !!
Follow up here for now.
