apiman gets an error when running under Docker-Machine in Windows 7

[merandall]

I started the default apiman in Docker-Machine under Windows 7. I modified the hosts file in Windows to map to the docker ip: 192.168.99.100 dockerhost. The Keycloak admin console works fine using http://dockerhost:8080/auth/admin, and the Wildfly admin works fine using http://dockerhost:9990, but when I try to log on using http://dockerhost:8080/apimanui, I get an exception after entering the default uid and pwd. apiman is not recognizing dockerhost.

23:22:52,778 ERROR [org.keycloak.adapters.OAuthRequestAuthenticator](default task-11) failed to turn code into token: java.net.UnknownHostException: dockerhost

If I map the docker ip to localhost: 192.168.99.100 localhost it works, but causes problems for other apps that need localhost to point to the windows host.
