when i add a host to rancher server the agent show error as follow:  
File “/usr/local/lib/python2.7/dist-packages/requests/models.py”, line 381, in prepare\_url  
raise InvalidURL(‘URL has an invalid label.’)  
requests.exceptions.InvalidURL: URL has an invalid label.

i think the rancher server in mac have a bug like this:  
the CATTLE\_URL is not correct.  
#!/bin/sh

export CATTLE\_REGISTRATION\_ACCESS\_KEY="registrationToken"  
export CATTLE\_REGISTRATION\_SECRET\_KEY="D8862A4CB58836C78460:1484326800000:NgSnGrW9cTW6HWQvxjUod81fxVU"  
export CATTLE\_URL="[http://192.168.155.2锛�8080/v1](http://192.168.155.xn--28080-yl0qo990d/v1)"  
export DETECTED\_CATTLE\_AGENT\_IP=“172.17.0.1”

so everybody do you have any solution for rancher right run on the macbook?  
how can config it?  
my rancher’s version is 1.3.1 and docker’s version is 1.12.6 for macoX

The registration URL contains some sort of unicode character that isn’t a colon (`:`) between the host and port.

Separately, you haven’t gotten far enough to hit problems yet but Rancher does not work well with Docker for Mac (d4m). D4m creates a Linux VM on your Mac and then employs a variety of tricks to make it appear that Docker is actually running locally on your Mac, but these do not fit well with the way networking works in CNI/Rancher.

We suggest regular VMs of some sort for trying Rancher; this is the script I use: [https://github.com/rancher/10acre-ranch/#docker-machine-on-macos](https://github.com/rancher/10acre-ranch/#docker-machine-on-macos)
