Question

为什么我的Kubernetes集群中有两个IP地址类别？

kubectl describe svc cara
Name:                     cara
Namespace:                default
Labels:                   app=cara
Annotations:              kubectl.kubernetes.io/last-applied-configuration:
                            {"apiVersion":"v1","kind":"Service","metadata":{"annotations":{},"labels":{"app":"cara"},"name":"cara","namespace":"default"},"spec":{"por...
Selector:                 app=cara
Type:                     NodePort
IP:                       10.100.35.240
Port:                     cara  8000/TCP
TargetPort:               cara/TCP
NodePort:                 cara  31614/TCP
Endpoints:                192.168.41.137:8000,192.168.50.89:8000
Port:                     vrde  6666/TCP
TargetPort:               vrde/TCP
NodePort:                 vrde  30666/TCP
Endpoints:                192.168.41.137:6666,192.168.50.89:6666
Port:                     rdp  3389/TCP
TargetPort:               rdp/TCP
NodePort:                 rdp  31490/TCP
Endpoints:                192.168.41.137:3389,192.168.50.89:3389
Session Affinity:         None
External Traffic Policy:  Cluster
Events:                   <none>

在完成主安装后，我做了：

kubeadm init --v=0 --pod-network-cidr=192.167.0.0/16
kubectl apply --v=0 -f https://docs.projectcalico.org/v3.6/getting-started/kubernetes/installation/hosted/kubernetes-datastore/calico-networking/1.7/calico.yaml

我希望群集网络中有一个IP地址范围。我误会了吗？

Answer 1

Kubernetes集群中有两个主要的CIDR-Pod网络和服务网络。看来您的群集具有Pod网络192.168.0.0/16和服务网络10.0.0.0/8。

群集中的A类和C类IP地址
