Question

我在使用容器优化的VM时遇到了问题。我使用以下命令启动实例：

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"

其中m2.yml是：

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

当我ssh到实例并查看/var/log/docker.log时，我看到了：

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，docker images -a说：

REPOSITORY                       TAG                 IMAGE ID            CREATED              VIRTUAL SIZE
gcr.io/google_containers/pause   0.8.0               2c40b0526b63        11 weeks ago         241.7 kB

容器引擎是否遇到问题或我做错了什么？

UPDATE1

我尝试了an example：

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

并且日志中仍然存在错误：

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"

我即将通过反馈表单发送反馈，但提交失败时显示：relay__en.js?authuser=1:182 Uncaught TypeError: Cannot set property 'vmFeedbackData' of undefined。这样的故事。

Answer 1

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（以及相应的yaml更改）。

最新版本的container vm documentation显示了使用v1 API的yaml示例。

我遇到了类似的问题，解决方案结果是我试图使用

securityContext:
  privileged: true

Kubernetes在不使用Google容器群集（即google-container-manifest或{{因此，它永远不会将图像正确加载到实例上。

删除该属性解决了我的问题。

Google Container Registry是否会出现问题？
