nginx和metallLB后面的服务不可访问

Question

我有一个带有金属LB和ngnix的裸金属kubernetes集群，我可以在端口80上访问nginx并查看欢迎页面。我应用了一个Ingress资源，但我无法访问我的服务，尽管我可以通过工作程序(在指定的节点端口上(访问服务。这里有我遗漏的东西吗？

入口：

apiVersion: networking.k8s.io/v1beta1 # for versions before 1.14 use extensions/v1beta1
kind: Ingress
metadata:
name: ingress
spec:
rules:
- http:
paths:
- path: /rest/endpoints/hello
backend:
serviceName: microservices-service
servicePort: 8085
- path: /rest/endpoints/calculateIterationTotalCapcity
backend:
serviceName: microservices-service
servicePort: 8085

服务：

apiVersion: v1
kind: Service
metadata:
name: microservices-service
spec:
selector:
app: microservices-deployment
ports:
- port: 8085
targetPort: 8085
nodePort: 30000
type: NodePort

部署：

apiVersion: apps/v1
kind: Deployment
metadata:
name: microservices-deployment
labels:
app: microservices-deployment
spec:

更新：我能够追踪日志，我看到了这些可疑的日志：

Answer 1

错误消息：No such file or directory来自Nginx，指向导致错误请求的错误配置。

修复它的最简单方法是简单地创建一个目录/文件来匹配Nginx配置或调整配置本身。

请记住，还要检查目录/文件的权限，并在需要时使用chown命令进行更新。
