gcloud connect to docker Daemon fail

Question

I'm trying to test the new managed VM feature, following this tutorial (using OS X)

The boot2docker installation it's okay. Executing $(boot2docker shellinit) give the following output:

Writing /Users/guilhermetorres/.boot2docker/certs/boot2docker-vm/ca.pem
Writing /Users/guilhermetorres/.boot2docker/certs/boot2docker-vm/cert.pem
Writing /Users/guilhermetorres/.boot2docker/certs/boot2docker-vm/key.pem
    export DOCKER_HOST=tcp://192.168.59.103:2376
    export DOCKER_CERT_PATH=/Users/guilhermetorres/.boot2docker/certs/boot2docker-vm
    export DOCKER_TLS_VERIFY=1

boot2docker status print running

and boot2docker version print Boot2Docker-cli version: v1.5.0

Although when I try to run my application using gcloud --verbosity debug preview app run

I got this error:

ERROR    2015-03-05 00:36:39,816 containers.py:742] Failed to connect to Docker Daemon due to: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)

You can see the EV variables:

Please check if the environment variables DOCKER_HOST, DOCKER_CERT_PATH and DOCKER_TLS_VERIFY are set correctly. If you are using boot2docker, you can set them up by executing the commands that are shown by:
boot2docker shellinit

After reading this issue https://github.com/docker/docker-py/issues/465, and uninstall homebrew (brew remove python)Python everything works fine.
