我在使用容器优化虚拟机时遇到了问题。我使用以下命令启动一个实例：

gcloud compute instances create "$instance_name" \
    --tags "http-server" \
    --image container-vm \
    --scopes storage-rw,logging-write \
    --metadata-from-file google-container-manifest="m2.yml" \
    --zone "$my_zone" \
    --machine-type "$my_machine_type"

哪里m2.yml是：

version: v1beta2
containers:
  - name: nginx
    image: nginx

当我 ssh 到实例并查看时，/var/log/docker.log我看到：

time="2015-06-17T07:42:59Z" level=error msg="Handler for GET /containers/{name:.*}/json returned error: no such id: kubelet" 
time="2015-06-17T07:42:59Z" level=error msg="HTTP Error: statusCode=404 no such id: kubelet" 
time="2015-06-17T07:42:59Z" level=info msg="GET /version" 
time="2015-06-17T07:42:59Z" level=info msg="+job version()" 
time="2015-06-17T07:42:59Z" level=info msg="-job version() = OK (0)" 
time="2015-06-17T07:42:59Z" level=info msg="GET /containers/docker-daemon/json" 
time="2015-06-17T07:42:59Z" level=info msg="+job container_inspect(docker-daemon)" 
no such id: docker-daemon
time="2015-06-17T07:42:59Z" level=info msg="-job container_inspect(docker-daemon) = ERR (1)" 
time="2015-06-17T07:42:59Z" level=error msg="Handler for GET /containers/{name:.*}/json returned error: no such id: docker-daemon" 
time="2015-06-17T07:42:59Z" level=error msg="HTTP Error: statusCode=404 no such id: docker-daemon"

实例上没有运行容器并docker images -a说：

REPOSITORY                       TAG                 IMAGE ID            CREATED              VIRTUAL SIZE

容器引擎是否遇到一些问题或者我做错了什么？

更新1

我举了一个例子：

version: v1 kind: Pod spec: containers: - name: simple-echo image: gcr.io/google_containers/busybox command: ['nc', '-p', '8080', '-l', '-l', '-e', 'echo', 'hello world!'] imagePullPolicy: Always ports: - containerPort: 8080 hostPort: 8080 protocol: TCP restartPolicy: Always dnsPolicy: Default

并且在日志中仍然是错误： 

evgeny@instance:~$ cat /var/log/docker.log | grep error
time="2015-06-18T16:28:56Z" level=error msg="Handler for GET /containers/{name:.*}/json returned error: no such id: kubelet"

time="2015-06-18T16:28:56Z" level=error msg="HTTP Error: statusCode=404 No such image: gcr.io/google_containers/busybox"

我正要通过反馈表发送反馈，但提交失败：relay__en.js?authuser=1:182 Uncaught TypeError: Cannot set property 'vmFeedbackData' of undefined。这样的故事。

最新的容器 vm 映像不支持 v1beta2 kubernetes API。您需要更新清单以使用 v1beta3 或 v1（具有相应的 yaml 更改）。

最新版本的容器 vm 文档显示了一个使用 v1 API 的 yaml 示例。

我遇到了类似的问题，结果证明我正在尝试使用

securityContext:
  privileged: true

在不使用 Google Container 集群（即在 a或 a上使用google-container-manifest元数据项）将 docker 映像加载到 GCE 实例时，Kubernetes 不支持该属性，因此它永远不会将映像正确加载到实例上。compute.v1.instancecompute.v1.instanceTemplate

删除该属性解决了我的问题。
