lornajane opened a new issue #108: make quick-start fails when DOCKER_HOST isn't set
URL: https://github.com/apache/incubator-openwhisk-devtools/issues/108
 
 
   When I run `make quick-start`, the task just hangs.  I ran each task individually and the problem is that the `DOCKER_HOST_IP` (set on line 14) is empty.  This is because newish docker ships with the HTTP API disabled, so I have my `DOCKER_HOST` empty otherwise all my docker commands fail.
   
   I'm not sure what the "right" way of getting the IP address for machines configured this way would be (I'm on Ubuntu 17.10), for example I can ask my computer what it thinks its IP is but I believe the second entry here is the right one:
   
   ```
   $ hostname -I
   10.1.0.121 172.17.0.1 172.18.0.1 
   ```
   
   A script like this works perfectly, but I am not sure if it's "safe" or what the right thing to do is on other platforms.
   ```
   $ hostname -I|cut -f2 -d ' '
   172.17.0.1
   ```
