这篇具有很好参考价值的文章主要介绍了K8s的ingress-nginx配置https。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

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
