## 一、自签证书&&创建ingress规则 ##

## ingress配置https访问，这里使用自签证书实现https访问
    
    openssl req -x509 -sha256 -nodes -days 365 -newkey rsa:2048 -keyout tls.key -out tls.crt -subj "/C=CN/ST=JS/L=CZ/O=Acme, Inc./CN=*.yaoyao.com"
    kubectl create secret tls tls-secret --key=tls.key --cert=tls.crt -n myapp
    kubectl apply -f test-ing-https.yml

### test-ingress-https.yaml ###

# 启动了一个nginx服务nginx-svc3，ingress的tls-secret为之前创建的secret
    apiVersion: apps/v1
    kind: Deployment
    metadata:
      name: nginx-deployment3
      namespace: myapp
    spec:
      replicas: 1
      selector:
        matchLabels:
          app: nginx-backend3
      template:
        metadata:
          labels:
            app: nginx-backend3
        spec:
          containers:
          - name: nginx
            image: docker.io/library/nginx:latest
            imagePullPolicy: IfNotPresent
    ---
    apiVersion: v1
    kind: Service
    metadata:
      name: nginx-svc3
      namespace: myapp
    spec:
      ports:
      - targetPort: 80
        port: 80
      selector:
        app: nginx-backend3
    ---
    apiVersion: networking.k8s.io/v1
    kind: Ingress
    metadata:
      name: nginx-ing3
      namespace: myapp
    spec:
      ingressClassName: nginx
      tls:
      - hosts: 
        - www.yaoyao.com
        secretName: tls-secret
      rules:
      - host: www.yaoyao.com
        http:
          paths:
          - path: /
            pathType: Prefix
            backend:
              service:
                name: nginx-svc3
                port:
                  number: 80

## 二、测试https访问 ##

在另一台机器上配置hosts解析www.yaoyao.com，然后访问 curl --cacert tls.crt https://www.yaoyao.com:10443  
**这里的10443端口是ingress-nginx-controller服务暴露的nodeport端口**
