如何在谷歌容器引擎上运行 docker 镜像？

Question

我正在尝试在 Google Container Engine 中运行 docker 映像。该实例没有运行 docker 镜像。我可以 ssh 并运行 docker 命令，然后服务就会启动。但是当我从终端启动实例时什么也没有发生。有人可以看看我做错了什么。

我的 docker 文件看起来像

FROM golang
RUN mkdir -p /app
COPY . /app
RUN go get golang.org/x/tools/cmd/present
ENTRYPOINT cd /app && /go/bin/present -http=":8080"
EXPOSE 8080

containers.yaml 看起来像

version: v1beta3
containers:
  - name: talks
    image: sheki/talks 
    ports:
      - name: http-port
        containerPort: 8080
        hostPort: 80'

启动实例的命令是

gcloud compute instances create zoop \
    --image container-vm \
    --metadata-from-file google-container-manifest=containers.yaml \
    --zone us-central1-a \
    --machine-type f1-micro

您在问题中提到您使用的是谷歌容器引擎，但实际上您使用的是container vm（有点不同）。如果您想使用容器引擎，请查看文档以创建container cluster。

我运行了您的示例，在 /var/log/kubelet.log 中看到以下错误：

E0519 17:05:41.285556    2414 http.go:54] Failed to read URL: http://metadata.google.internal/computeMetadata/v1beta1/instance/attributes/google-cont

', but couldn't parse as neither single (error unmarshaling JSON: json: cannot unmarshal string into Go value of type int: {Version:v1beta3 ID: UUID:

Port":8080,"hostPort":"80'","name":"http-port"}]}],"version":"v1beta3"}').

容器 vms 的文档似乎已过时。
