Kubernetes pod 卡在等待状态

Question

试图启动这个 pod

apiVersion: v1
kind: Pod
metadata:
  name: tinyproxy
spec:
  containers:
    - name: master
      image: asdrepo.isus.emc.com:8091/francisbesset/tinyproxy
      env:
        - name: MASTER
          value: "true"
      ports:
        - containerPort: 6379
      resources:
        limits:
          cpu: "0.1"
      volumeMounts:
        - mountPath: /tinyproxy-data
          name: data
  volumes:
    - name: data
      emptyDir: {}

这会卡在待处理状态。我查看了故障排除指南，但这个 pod 似乎没有任何事件

$ kubectl describe pods tinyproxy
Name:       tinyproxy
Namespace:  default
Node:       /
Labels:     name=tinyproxy
Status:     Pending
IP:
Controllers:    <none>
Containers:
  master:
    Image:  asdrepo.isus.emc.com:8091/francisbesset/tinyproxy
    Port:   6379/TCP
    QoS Tier:
      cpu:  Guaranteed
      memory:   BestEffort
    Limits:
      cpu:  100m
    Requests:
      cpu:  100m
    Environment Variables:
      MASTER:   true
Volumes:
  data:
    Type:   EmptyDir (a temporary directory that shares a pod's lifetime)
    Medium:
No events.

还有

代理似乎正在运行并且没有重新启动

我该如何调试？

Answer 1

看起来调度程序服务没有启动（这是在一个 openstack 虚拟机中）。所有服务都应该自动配置和启动。这在我手动启动服务后起作用。
