Question

我目前正在尝试通过HTTPS连接并使用端口443的SkyDNS。

I1221 01:15:28.199437       1 server.go:91] Using https://10.100.0.1:443 for kubernetes master
I1221 01:15:28.199440       1 server.go:92] Using kubernetes API <nil>
I1221 01:15:28.199637       1 server.go:132] Starting SkyDNS server. Listening on port:10053

我希望它使用HTTP和端口8080代替。

我的YAML文件是：

apiVersion: v1
kind: ReplicationController
spec:
  replicas: 1
  selector:
    k8s-app: kube-dns
    version: v18
  template:
    metadata:

      labels:
        k8s-app: kube-dns
        kubernetes.io/cluster-service: "true"
        version: v18
    spec:

        ports:

      - args:
        - -cmd=nslookup kubernetes.default.svc.kube.local 127.0.0.1 >/dev/null &&
          nslookup kubernetes.default.svc.kube.local 127.0.0.1:10053 >/dev/null
        - -port=8080
        - -quiet
        image: gcr.io/google_containers/exechealthz-amd64:1.0
        imagePullPolicy: IfNotPresent
        name: healthz
        ports:
        - containerPort: 8080
          protocol: TCP
        resources:
          limits:
            cpu: 10m
            memory: 20Mi
          requests:
            cpu: 10m
            memory: 20Mi

我知道这可能不是一个有利的设计，但有没有办法可以改变协议和端口？

Answer 1

将以下内容添加到kubedns的spec.containers.args部分就可以了。

 - --kube-master-url=http://master:8080

禁用https并更改SKyDNS的端口
