Am I trying to connect to a TLS-enabled daemon without TLS?

Question

I\'m trying to learn about Docker, but I keep getting cryptic (to me) error messages.

Answer 1

I tried the solutions here, and boot2docker didn't work.

My solution: Uninstall boot2docker on the Mac, install a Centos 7 VM in VirtualBox, and work with Docker inside that VM.
