Seeing up NodeBB with docker isn't officially supported. I suggest you use the Ubuntu guide: https://docs.nodebb.org/installing/os/ubuntu/
Server control panels
I'm currently looking into different server control panels. I have previously used cPanel and Virtualmin but now I am configuring everything manually through command line.
What control panels are everyone using? or are you people the down and dirty command line type of people?
Which would you recommend?
