所以我使用CoreOS手册安装指南中的Kubernetes启动并运行了kubernets集群.

$ kubectl get no
NAME              STATUS                     AGE
coreos-master-1   Ready,SchedulingDisabled   1h
coreos-worker-1   Ready                      54m

$ kubectl get cs
NAME                 STATUS    MESSAGE              ERROR
controller-manager   Healthy   ok
scheduler            Healthy   ok

$ kubectl get pods --all-namespaces -o wide

我设置了一个简单的redis ClusterIP服务，供集群内部的php LoadBalancer服务访问。php日志显示连接超时错误。Redis服务不可访问。

'production'.ERROR: Operation timed out {"exception":"[object] (RedisException(code: 0): 
Operation timed out at /var/www/html/vendor/laravel/framework/src/Illuminate/Redis
/html/vendor/laravel/framework/src/Illuminate/Redis/Connectors/PhpRedisConnector.php(109): 
    Redis->connect('redis-svc', '6379', 0, '', 0, 0)

我的redis服务非常简单，所以我不知道出了什么问题：

    io.kompose.service: redis
  name: redis

  replicas: 1
