1.问题描述
在GCP上构建完镜像后，想执行docker push相应镜像上去的时候发现返回一个问题：
The push refers to repository [gcr.io/starcloud-200123/clustarai/jupyterhub]

解决这个问题，主要是GCP本身的机器人文档实在是太难读懂了。。。
2.解决
解决这个问题也就是一个权限问题，首先你的GCP账户本身是有对这个项目进行修改的权限的，接着你需要执行以下步骤。
- 1.登入你的GCP账号，一般是google账号
$ gcloud auth login
在这里面输入你的用户名，然后复制一条链接到浏览器中，拿到一个verification code,填里面即可。
- 2.设置到你的project
$ gcloud config set project starcloud-200123 # starcloud-200123需要改成你自己的project
输出:
Updated property [core/project].
- 3.确认docker配置
$ gcloud auth configure-docker
输出：
gcloud credential helpers already registered correctly.
- 4.login你的位置
$ docker login gcr.io # gcr.io需要改成你自己的project位置
输出：
Authenticating with existing credentials...
Login Succeeded
- 5.push 你的镜像
$ docker push gcr.io/starcloud-200123/clustarai/jupyterhub
输出：
The push refers to repository [gcr.io/starcloud-200123/clustarai/jupyterhub]
