测试:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-nginx
spec:
  selector:
    matchLabels:
      app: my-nginx
  template:
    metadata:
      labels:
        app: my-nginx
    spec:
      containers:
      - name: my-nginx
        image: nginx
        ports:
        - containerPort: 80
---
apiVersion: v1
kind: Service
metadata:
  name: my-nginx
  labels:
    app: my-nginx
spec:
  ports:
  - port: 80
    protocol: TCP
    name: http
  selector:
    app: my-nginx

ingress不带tls:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: my-nginx
  namespace: default
spec:
  ingressClassName: nginx  # 使用 nginx 的 IngressClass（关联的 ingress-nginx 控制器）
  rules:
  - host: www.lanpanpan123.com  # 将域名映射到 my-nginx 服务
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:  # 将所有请求发送到 my-nginx 服务的 80 端口
            name: my-nginx
            port:
              number: 80

制作证书脚本

#!/bin/bash

domain=www.lanpanpan123.com

openssl genrsa -out tls.key 2048
openssl req -new -x509 -key tls.key -out tls.crt -subj /C=CN/ST=Beijing/L=Beijing/O=DevOps/CN=${domain}

kubectl create secret tls my-ingress-secret --cert=tls.crt --key=tls.key

使用上一步生成的secret创建tls的ingress

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: my-nginx-tls
  namespace: default
spec:
  ingressClassName: nginx  # 使用 nginx 的 IngressClass（关联的 ingress-nginx 控制器）
  tls:
  - hosts:
    - www.lanpanpan123.com
    secretName: my-ingress-secret
  rules:
  - host: www.lanpanpan123.com  # 将域名映射到 my-nginx 服务
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:  # 将所有请求发送到 my-nginx 服务的 80 端口
            name: my-nginx
            port:
              number: 80

使用上一步脚本生成的tls.crt访问
