I think I would start by looking at how-to craft that container by hand. You'll understand the fundamentals better if you do it that way. Once you have a grasp of those, research the tools that then do it for you.

If you deploy a container to a Cloud provider, you'll need to first setup and understand the container engine as well. Not a bad thing to learn, for sure, but again start small and from the bottom upwards.

My tutorials won't cover containerisation because frankly I believe they're overkill for most situations. Sure they're fast and so on, but a slower golden image and a simple EC2 Instance in an AutoScaling Group is easier to understand, manage, and can be just as easily orchestrated.
