ingress

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-httpnamespace: dev
spec:rules:- host: nginx.itheimahttp:paths:- path: /backend:serviceName: nginx-serviceservicePort: 80- host: tomcat.itheimahttp:paths:- path: /backend:serviceName: tomcat-serviceservicePort: 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

正确的yaml配置

apiVersion: networking.k8s.io/v1    # 注意最新的官方给定
kind: Ingress
metadata:name: ingress-httpnamespace: dev
spec:rules:- host: nginx.itheimahttp:paths:- path: /pathType: Prefix   #  requiredbackend:serviceName: nginx-serviceservicePort: 80- host: tomcat.itheimahttp:paths:- path: /pathType: Prefix   #  requiredbackend:serviceName: tomcat-serviceservicePort: 8080
