Didn't know whether to put this in Virtualization or here in Off-Topic:
On Reddit saw a Udemy course for Docker that seems to be pretty complete. It's not part of the normal Udemy promotions as of now, but there's a Reddit code for 20% off at the moment.
I can't give a review on how complete it is or the quality, but I just grabbed it and plan on starting it tomorrow.
