我们平常使用k8s的service都是自动发现增加endpoint的，但是有的时候集群外的服务我们又想用k8s的ingress来统一做入口，就会涉及到自定义endpoint

## 创建service

```yml
apiVersion: v1
kind: Service
metadata:
  name: kibana
  namespace: ops
spec:
  type: ClusterIP
  ports:
  - name: kibana
    port: 80
    protocol: TCP
    targetPort: 80
```

## 创建endpoint

```yml
apiVersion: v1
kind: Endpoints
metadata:
  name: kibana
  namespace: ops
subsets:
- addresses:
  - ip: 10.0.0.12
  - ip: 10.0.0.13
  ports:
  - name: kibana
    port: 5601
    protocol: TCP
```

## 创建Ingress

```yml
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: kibana
  namespace: ops
  annotations:
    kubernetes.io/ingress.class: "nginx"
    nginx.ingress.kubernetes.io/proxy-body-size: 300M
    nginx.ingress.kubernetes.io/server-snippet: |
      if ($http_user_agent ~* (Scrapy|Go-http-client/1.1|HttpClient|curl/7.64.1)) {
        return 403;
      }
spec:
  rules:
  - host: kibana.ingeek.com
    http:
      paths:
      - backend:
          serviceName: kibana
          servicePort: 80
        path: /
```
