The issue

• deployed a local docker registry container to a docker-machine VM
• cannot push to local docker registry
• get an error including a message similar to, "http: server gave HTTP response to HTTPS client"

The solution

• in order to push to this local registry you need to make some modifications to your docker VM
• open c:\users\<user-name>\.docker\machine\machines\default\config.json or ~/.docker/machine/machines/default/config.json in an editor
• find the InsecureRegistry property and append "localhost:5000" to it
• go to your docker terminal
