我正在尝试使用自定义图像在 Google Cloud AI Platform 上启动笔记本。我遵循了这里描述的做法：
https://cloud.google.com/ai-platform/deep-learning-containers/docs/derivative-container
所以要构建和推送 docker 镜像：
gcloud auth configure-docker
export PROJECT=$(gcloud config list project --format "value(core.project)")
docker build . -f Dockerfile -t "gcr.io/${PROJECT}/my-custom-image:latest"
docker push "gcr.io/${PROJECT}/my-custom-image:latest"
但是，当尝试使用此图像连接到笔记本实例时
gcloud compute --project "myproject" ssh --zone "myzone" "custom-test" -- -L 8080:localhost:8080
我明白了
ssh: connect to host XXX.XXX.XXX.XXX port 22: Connection refused
即使我只使用基本映像而不做任何更改，也会发生这种情况，例如使用这个 Dockerfile：
FROM gcr.io/deeplearning-platform-release/base-cpu:latest
如果我直接启动一个笔记本实例，gcr.io/deeplearning-platform-release/base-cpu:latest我可以按预期连接到它。

似乎是权限错误，但我不确定为什么我无权部署从同一帐户推送的图像。会不会有关系custom-test ntpd[707]: kernel reports TIME_ERROR: 0x41: Clock Unsynchronized？
编辑 2：现在，大约一个小时后，我可以连接（没有进行任何更改）。但是当访问localhost:8080我得到：
channel 4: open failed: connect failed: Connection refused
channel 3: open failed: connect failed: Connection refused
作为附加控制台中的输出。
