This is the outline of a small reading group that has already ended, based on the descriptions provided on their website. I don't think there is a Discord group associated with it, I would like to join if there is one though.

Yes surely there is one you can give me your discord name so I can chat you up.

There is an open source cooking guide for programmer. Unfortunately, its for chinese reader only.

I use the same strategy.

I started my docker journey with this awesome tutorial. (https://www.youtube.com/watch?v=9zUHg7xjIqQ)

Also, the slides at the self-paced tutorial section might be helpful to you.(https://container.training/)

Looks great; very substantive. Do you think I'd survive if I haven't done any express, node or mongo before? (I'm willing to give it a shot, but not sure if it would be sensible because I could get stuck and spend time on issues unrelated to docker).

I'll be watching it in its entirety either way.

You're right, but this tutorial is using some very basic node and express stuff, really just a few lines of code. If you think that the node stuff in the first few minutes in this tutorial is overwhelming, then probably it is not quite suitable for you, but if you fell like you're comfortable with the first few minutes, then you're good to go, the node and express stuff in latter part of the video couldn't get any harder.

Disclaimer: I do know node and express when I was following this tutorial.
