部署集群外部服务

1.以webhook服务为咧

服务访问地址如下
http://10.41.1.20:9001/hooks/test-webhook?token=5656
ip+端口的方式（10.41.1.20:9001）
测试端口是否正常

root@devops-test:~# telnet 10.41.1.20 9001
Trying 10.41.1.20...
Connected to 10.41.1.20.
Escape character is '^]'.

配置k8s的yaml文件测试链接性

service.yaml文件

apiVersion: v1
kind: Service
metadata:
  name: webhook
spec:
  type: ClusterIP
  ports:
  - port: 9001
    targetPort: 9001
    name: webhook

endpoints.yaml文件

apiVersion: v1
kind: Endpoints
metadata:
  name: webhook
subsets:
- addresses:
  - ip: 10.41.1.20
  ports:
  - port: 9001
    protocol: TCP
    name: webhook

ingress-service.yaml文件

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: webhook
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /
spec:
  rules:
    - host: webhook.test.com
      http:
        paths:
          - path: /
            pathType: Prefix
            backend:
              service: 
                name: webhook
                port:
                  servicePort: 9001
