我正在使用shippable将私有docker映像推送到Google容器注册表，然后再从笔记本电脑本地或Google Compute
Engine实例内部提取。

我知道该命令gcloud preview docker pull gcr.io/projectID/image- name有效，但是我不能依赖gcloud被安装在有人可能需要从中提取映像的每台计算机上。

如果我docker-compose up -d在计算机上运行，则会出现以下错误：

Pulling image gcr.io/projectID/image-name...
Pulling repository gcr.io/projectID/image-name
Traceback (most recent call last):

是否可以通过某种形式的OAuth或密钥来认证或访问图像？我想避免在需要拉取映像的每台计算机上安装gcloud，并且映像必须保持私有。

我已经尝试过了，gcloud preview docker -a但这不是我要寻找的解决方案。

预先感谢您的任何帮助。
