根据一些参考文档，学习部署 ingress-http服务，出现了一些error信息，网上难找直接的处理方式，最后才发现是资源清单使用问题，还是得看官方文档说明。

创建ingress-http.yaml

使用的基本yaml配置如下——

# 文件名称： ingress-http.yaml
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ingress-http
  namespace: dev
spec:
  rules:
  - host: nginx.itheima.com
    http:
      paths:
      - path: /
        backend:
          serviceName: nginx-service
          servicePort: 80
  - host: tomcat.itheima.com
    http:
      paths:
      - path: /
        backend:
          serviceName: tomcat-service
          servicePort: 8080

部署ingress服务

# 部署服务
kubectl create -f ingress-http.yaml

出现error信息

错误一：

error: resource mapping not found for name: "ingress-http" namespace: "dev" from "ingress-http.yaml": no matches for kind "Ingress" in version "extensions/v1beta1"
ensure CRDs are installed first

处理方式——

根据官方文档：Ingress对象资源清单说明

apiVersion: networking.k8s.io/v1

重新部署，仍然出现error信息

错误二：

* spec.rules[0].http.paths[0].pathType: Required value: pathType must be specified

paths下必须有pathType，否则创建就会失败，官方文档中也有说明

PS：附上官方文档的对应的截图

        pathType: Prefix   #  required
        backend:
          serviceName: nginx-service
          servicePort: 80
  - host: tomcat.itheima.com
    http:
      paths:
