google-app-engine - gcloud 连接到 docker 守护进程失败

Question

我正在尝试测试新的托管 VM 功能，遵循 tutorial (使用 OS X)

boot2docker安装没问题。执行 $(boot2docker shellinit) 给出以下输出:

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 状态 打印 正在运行

和boot2docker版本打印Boot2Docker-cli版本:v1.5.0

虽然当我尝试使用 gcloud --verbosity debug preview app run

运行我的应用程序时

我收到了这个错误:

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)

你可以看到 EV 变量:

还有完整的堆栈跟踪:

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

看完本期https://github.com/docker/docker-py/issues/465 ，然后卸载 homebrew (brew remove python)Python 一切正常。
