When I perform blockade up and submit them to the mistake, where is the problem? How to solve?

Unexpected error! This may be a Blockade bug.

Hello, please try with Docker version 1.9 or later.

I'm leaving this issue open because 1) Blockade probably doesn't need to actually require 1.9 and 2) we should handle this failure more gracefully.

Closing this issue. In 0.3.1, blockade has a couple of fixes that address problems discussed here:

  1. Vastly improved error handling around finding a container's interface
  2. ip is no longer required to be installed in containers. Instead Blockade directly reads the /sys FS to find the needed information from the container.
