Docker install fails on OSx

Question

I am trying to install new Docker on OSx.

It fails with following error.

Installation Failed.

Also the window opens where I can see two utilities:

• Docker Quick Terminal
• Kinematic

When I click Docker Quick Terminal I can type:

docker info

But when I type:

docker run

I get the error.

sudo docker run -i -t ubuntu /bin/bash

Answer 1

Just ran into the same thing. I did have a virtual machine running but was still getting that error when I tried to use the command line. When I ran docker-machine env default to see the state of my docker VM named default I was prompted to run a command, eval "$(docker-machine env default)" to initialize my shell. That step got everything working for me.

The details, as it turns out, are at the top of the README for docker/machine on github.

Answer 2

Check if vbox is running; if not, start it (replace default with your vbox name):

$ docker-machine start default

And then do as Kevin above replied:

eval "$(docker-machine env default)"
