Kubernetes:创建kube-dns服务 [英] Kubernetes: kube-dns Service Creation

问题描述

用IP 192.168.3.10编写skydns-svc.yml文件后，出现以下错误:

After writing a skydns-svc.yml file with the IP 192.168.3.10 I recieve the following error:

Error: The Service "kube-dns" is invalid:spec.clusterIP: Invalid value: "192.168.3.10": provided IP is not in the valid range

skydns-svc.yml

skydns-svc.yml

apiVersion: v1
kind: Service
metadata:
  name: kube-dns
  namespace: kube-system
  labels:
    k8s-app: kube-dns
    kubernetes.io/cluster-service: "true"
    kubernetes.io/name: "KubeDNS"
spec:
  selector:
    k8s-app: kube-dns
  clusterIP:  192.168.3.10
  ports:
  - name: dns
    port: 53
    protocol: UDP
  - name: dns-tcp
    port: 53
    protocol: TCP

这怎么不在有效范围内，我该如何解决错误?使用V1.2

How is this not in a valid range and how could I go about resolving the error? Using V1.2

推荐答案

您需要将clusterIP设置为"SERVICE_CLUSTER_IP_RANGE"中的IP，该IP是传递给kube的CIDR范围(通常为/16或更小). apiserver进程在--service-cluster-ip-range标志中.如果您选择该范围内的任何地址，您将不再收到上述错误.

You need to set the clusterIP to an IP in the "SERVICE_CLUSTER_IP_RANGE", which is a CIDR range (typically a /16 or smaller) passed to the kube-apiserver process in the --service-cluster-ip-range flag. If you pick any address in that range you should no longer receive the above error.
