将apiVersion：networking.k8s.io/v1beta1入口清单转换为apiVersion：networking.k8s.io/v1

Question

今年早些时候，我安装了一个带有nginx入口的kubernetes集群。虽然没有什么问题，但效果很好。对于入口，我使用了标签

apiVersion:networking.k8s.io/v1beta1

然而，我最近安装了最新版本的（kubernetes 1.22），它只允许

networking.k8s.io/v1

我的问题是使用我的旧yaml配置与新格式。

我的yaml文件如下所示：

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: dev-ingress
  annotations:
    nginx.ingress.kubernetes.io/proxy-body-size: "0"
    nginx.ingress.kubernetes.io/websocket-services : "chatserver"
    nginx.ingress.kubernetes.io/enable-cors: "true"
    nginx.ingress.kubernetes.io/cors-allow-methods: "PUT, GET, POST, OPTIONS"
    nginx.ingress.kubernetes.io/use-regex: "true"
spec:
  rules:
  - http:
      paths:     
      - path: /api/auth/
        pathType: Prefix
        backend:
          serviceName: um-service 
          servicePort: 5001
      - path: /api/system/*
        pathType: Prefix
        backend:
          serviceName: system-service
          servicePort: 5002
       - path: /api/news/*
        backend:
          serviceName: news-service 
          servicePort: 5003
      - path: /api/tasks/*
        # pathType: Prefix
        backend:
          serviceName: tasks-service
          servicePort: 5004
      - path: /api/chats/
        pathType: Prefix
        backend:
          serviceName: chatserver 
          servicePort: 5500
      - path: /
        backend:
          serviceName: web-service
          servicePort: 5000

我的新清单如下所示：

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: dev-ingress
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /
spec:
  rules:
  - http:
      paths:
      - path: /api/auth/
        pathType: Prefix
        backend:
          service:
            name: um-service 
            port: 
              number: 5001
      - path: /api/system/*
        pathType: Prefix
        backend:
          service:
            name: system-service 
            port: 
              number: 5002
      - path: /api/chats/
        pathType: Prefix
        backend:
          service:
            name: chatserver
            port: 
              number: 5050
      - path: /
        pathType: Prefix
        backend:
          service:
            name: web-service
            port: 
              number: 5000
  ingressClassName: nginx

如何将其转换为使用新的apiVersion:networking.k8s。io/v1标签？

Answer 1

幸运的是，就YAML而言，API版本之间没有太大差异。这是一个networking.k8s的示例。Kubernetes文档中的io/v1。

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: minimal-ingress
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /
spec:
  rules:
  - http:
      paths:
      - path: /testpath
        pathType: Prefix
        backend:
          service:
            name: test
            port:
              number: 80

对于您来说，主要的变化是如何完成后端块。例如：

backend:
  serviceName: tasks-service
  servicePort: 5004

需要成为：

backend:
  service:
    name: "tasks-service"
    port:
      number: 5004
