I am running Boot2Docker on Mac OS X 10.9.5 and I’ve found the Boot2Docker documentation severely lacking; there isn’t even a manpage! My unanswered questions about Boot2Docker (for now) are:
What exactly is the difference between
start? Why do we need both?
What happens if I run
starttwice? What happens if I run
startwithout first running
I appear that all of my Docker images are stored in the VM rather than on my system directly. Do I have to do anything special to ensure this data persists across reboots (of both the VM and my machine)?
What’s the preferred way to shut down the VM when I’m preparing to shut down my computer? If I forget to shut down the VM before shutting down my computer, will Bad Things™ happen? What if I perform an emergency restart of my computer? Will I need to perform some sort of cleanup afterwards to restore the VM and/or the downloaded images to a workable state?
