On Installation, stuck at "Docker is starting"

Expected behavior

After installing and copying from an existing Docker machine, the Docker for Mac application should start up in a reasonable amount of time.

Actual behavior

Upon installation, I copied from my existing machine and then the application said “Docker is starting” for a period of around 15 minutes. After quitting the application, I stopped the machine from the command line then re-ran Docker for Mac, and the application entered the “Docker is running” state within a matter of seconds. I would assume that this is due to the machine already running, but being unaware of the internals of operation I’m not quite sure.


Diagnostic ID: A56F7D04-0E38-40D0-854D-6695AB1DDD6E

Docker for Mac version v1.11.1-beta14.5.m
Using OSX El Capitan 10.11.5 (build 15F34)

Steps to reproduce the behavior

  1. docker-machine start using Docker Toolbox
  2. Install Docker for Mac, choosing to import from the existing machine.
  3. After import, when starting up, if the issue can be reproduced, clicking on the menu bar icon for Docker should say “Docker is starting” and stay in this state for a while (seemingly indefinitely, but one obviously cannot wait indefinitely).
  4. Quit the Docker for Mac application.
  5. docker-machine stop using Docker Toolbox
  6. Start the Docker for Mac application.
  7. The Docker for Mac application should show “Docker is running” after a reasonable amount of time when the menu bar icon is clicked.
