Hi Guys,
Sorry, Been a bit busy, did the matter most get a placing in the NethServer.
Ive been looking at including this on 5 of the 20 Nethservers we have installed at our company. and due to the complexity of communications, and vast apps that we use, Mattermost is the way to go, and I dont feel like setting up dockers?
Do this happen by anychance.
Mattermost is a powerful choice!
It could be valued from the integration perspective point of view.
All Nethserver’s modules could be integrated with the chat to offer a powerful environment. Think at something like notifications of server events by chat or configurations operated by a chat interface (with the help of a bot).
Looking for the specifications, I think that the docker installation could be the best choice, mainly for the database. It is advised either postgre9.4 (their choice) or mysql57
Anyway it is not the default version and you need to use the software collection
We have a new mattermost module 
Please move the discussion there:
