In order to use an insecure registry with Kitematic, you can follow the steps below:

  • Login to the Kitematic box, e.g. double click in VirtualBox on the kitematic machine that is named ‘default’ by default :-)
  • Edit the file /var/lib/boot2docker/profile and append to EXTRA_ARGS the --insecure-registry parameter:
EXTRA_ARGS='
...
--insecure-registry myregistrydomain.com:5000
'
  • Restart docker /usr/local/etc/init.d/docker restart

You should now be able to push an image to your insecure registry.
