Question

我正在使用谷歌容器引擎并在日志中获取大量的DNS错误。

像：

10:33:11.000 I0720 17:33:11.547023 1 dns.go:439] Received DNS Request:kubernetes.default.svc.cluster.local., exact:false

和

10:46:11.000 I0720 17:46:11.546237 1 dns.go:539] records:[0xc8203153b0], retval:[{10.71.240.1 0 10 10 false 30 0 /skydns/local/cluster/svc/default/kubernetes/3465623435313164}], path:[local cluster svc default kubernetes]

这是有效载荷。

{
  metadata: {
    severity: "ERROR"      
    serviceName: "container.googleapis.com"      
    zone: "us-central1-f"      
    labels: {
      container.googleapis.com/cluster_name: "some-name"        
      compute.googleapis.com/resource_type: "instance"        
      compute.googleapis.com/resource_name: "fluentd-cloud-logging-gke-master-cluster-default-pool-f5547509-"        
      container.googleapis.com/instance_id: "instanceid"        
      container.googleapis.com/pod_name: "fdsa"        
      compute.googleapis.com/resource_id: "someid"        
      container.googleapis.com/stream: "stderr"        
      container.googleapis.com/namespace_name: "kube-system"        
      container.googleapis.com/container_name: "kubedns"        
    }
    timestamp: "2016-07-20T17:33:11.000Z"      
    projectNumber: ""      
  }
  textPayload: "I0720 17:33:11.547023       1 dns.go:439] Received DNS   Request:kubernetes.default.svc.cluster.local., exact:false"    
  log: "kubedns"    
}

一切正常，只是日志被错误污染了。关于为什么会这样或者我应该关注的任何想法？

感谢您提出的问题，Aaron。这些错误消息实际上只是从容器中跟踪/调试输出，并不表示出现任何问题。他们被写成错误消息的事实已在Kubernetes中得到修复，并且在下一版Kubernetes中会更好。
