Satsangat> HPC is using Mattermost for instant messaging [...] That's cool that they are going with a free s/w solution; the central lab approach is "skype for business", continuing central IT's proud history of picking proprietary and lame approaches. This raises another interesting quesiton. I took a quick stab at installing matrix-synapse, mattermost and "let's chat". matrix-synapse is packaged in debian/ubuntu and seems to not need too much other config, which is kind of cool. On the other hand mattermost needs a mysql setup, and mattermost needs a mongodb setup. So here's my question: powerful as the heavy-duty databases are, when I do a small-scale deployment I prefer to pick the SQLite option if they have it. But often (like with mattermost) they don't have that option. So I have to deal with yet another mysql setup, which is annoying. Has anyone found a state of joy in their handling of many sql setups for random bits of web backend s/w on their host? What's your secret? How do you automate and set up an "unattended reinstall" when passwords are involved?
