我需要在Minikube上找Kafka和Cassandra
主机操作系统是Ubuntu 16.04
$ uname -a
Linux minikuber 4.4.0-31-generic #50-Ubuntu SMP Wed Jul 13 00:07:12 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
Minikube正常开始：
$ minikube start
Starting local Kubernetes v1.8.0 cluster...
Starting VM...
Getting VM IP address...
Moving files into cluster...
Setting up certs...
Connecting to cluster...
Setting up kubeconfig...
Starting cluster components...
Kubectl is now configured to use the cluster.
服务清单：
$ kubectl get services
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
kubernetes ClusterIP 10.0.0.1 <none> 443/TCP 1d
Zookeeper和Cassandra正在运行，但kafka崩溃并出现错误“CrashLoopBackOff”
$ kubectl get pods
NAME READY STATUS RESTARTS AGE
zookeeper-775db4cd8-lpl95 1/1 Running 0 1h
cassandra-d84d697b8-p5wcs 1/1 Running 0 1h
kafka-6d889c567-w5n4s 0/1 CrashLoopBackOff 25 1h
查看日志：
kubectl logs kafka-6d889c567-w5n4s -p
输出：

任何人都可以帮忙解决重启容器的问题吗？
kubectl describe pod kafka-6d889c567-w5n4s
