Nice and you have some interesting packages I have not touched. I just bought the course to help out :-) and lets see if I can run it on my Raspberry PI here cluster at home I recently built up.
A little more than $500/mon at the moment. If you are to trust Udemy's "instructor marketplace insights", top courses with the keyword 'devops' are north of $10k/mon, but median is just $27/mon.
