Instructor Notes

See the setup for important instructor notes on setting up the lesson and possible troubleshooting steps on installing VirtualBox.

Lead off script: We’re all familiar with computers like Macs and PCs. They run an operating system like Windows or Mac, and we can run programs on that computer like web browsers and word processors. The operating system controls all of the physical resources.

Explain the diagram

Physical resources, and how the OS controls access to them
The VMM is a program that gets a slice of those resources and presents them as if they were physical resources to virtual machines
Define the relationship between the host and guest OS.
Use the concept of a computer-within-a-computer

Basics of Containers with Docker

Instructor Note

Instructors should feel free to add their own examples in the introduction, to help your learners appreciate the utility of containers. Providing your own use case of containers helps lend authenticity to the lesson.

Instructor Note

TODO: Anything the instructor should be aware of. Maybe here’s a point for an image of some sorts.

Instructor Note

The instructions included in the two episodes on containers assume that learners are using the virtual machines described in prior episodes. However, the following Docker instructions can all be run on any computer that has an internet connection and has Docker installed. You can find more information about installing Docker at the Carpentries’ Containers lesson.
