一、集群外訪問（負載均衡）
kind: Service
apiVersion: v1
spec:
ports:
- protocol: TCP
port: 4341
targetPort: 8080
nodePort: 30875
type: LoadBalancer
externalIPs: #外部負載均衡
- 172.30.10.4
- 172.30.10.3
sessionAffinity: None
externalTrafficPolicy: Cluster
status:
loadBalancer:
ingress:
- {}
二、k8s集群內訪問
kind: Service
apiVersion: v1
spec:
ports:
- protocol: TCP
port: 4321
targetPort: 8080
type: ClusterIP
externalIPs: #集群內互訪
- 172.30.10.201

sessionAffinity: None
status:
loadBalancer: {}
三、vpc內網負載均衡
kind: Service
apiVersion: v1
metadata:
annotations:
kubernetes.io/elb.class: elasticity #表示選擇的是經典負載均衡實例
kubernetes.io/elb.vpc.id: 0e86e303-7a82-4e03-a435-9be0c4771c93 #負載均衡所在vpc的ID
spec:
ports:
- name: cce-service-0
protocol: TCP
port: 4321
targetPort: 8080
nodePort: 31118
type: LoadBalancer
loadBalancerIP: 172.30.12.33
sessionAffinity: None
externalTrafficPolicy: Cluster
status:
loadBalancer:
ingress:
- ip: 172.30.12.33
四、集群外訪問，NodePort
apiVersion: v1
kind: Service
metadata:
labels:
app: prometheus-operator-operator
name: my-release-prometheus-oper-operator
namespace: default
spec:
ports:
- name: http
port: 8080
protocol: TCP
targetPort: http
nodePort: 30080
selector:
app: prometheus-operator-operator
sessionAffinity: None
type: NodePort
#clusterIP: None 這里不能設置為空，因為nodeport需要映射到clusterip
status:
loadBalancer: {}
