#  创建Ingress资源提供访问

## 准备工作

1. 部署 Nginx 资源

   ```yaml
   kubectl apply -f https://gitee.com/offends/Kubernetes/raw/main/File/Yaml/nginx-deployment.yaml
   kubectl apply -f https://gitee.com/offends/Kubernetes/raw/main/File/Yaml/nginx-deployment-svc.yaml
   ```

2. 查看部署情况

   ```bash
   kubectl get deploy,svc
   ```

## 示例

1. 创建对外域名证书

   ```bash
   kubectl create secret tls nginx-tls --key nginx.key --cert nginx.pem -n default
   ```

2. 创建 Ingress 资源

   - HTTP

     ```yaml
     cat <<EOF | kubectl apply -f -
     apiVersion: networking.k8s.io/v1
     kind: Ingress
     metadata:
       name: nginx-ingress
       namespace: default
       annotations:
         # 不限制文件上传大小 或 选择其他参数
         nginx.ingress.kubernetes.io/proxy-body-size: "0"
       labels:
         name: nginx-ingress
     spec:
       ingressClassName: nginx # 通过 kubectl get ingressclass 查看
       rules:
       - http:
           paths:
           - backend:
               service:
                 name: nginx-service # Nginx Serice 名称
                 port:
                   number: 80 # Nginx 端口
             path: /
             pathType: Prefix
     EOF
     ```

   - HTTPS

     ```yaml
     cat <<EOF | kubectl apply -f -
     apiVersion: networking.k8s.io/v1
     kind: Ingress
     metadata:
       name: nginx-ingress
       namespace: default
       annotations:
         # 不限制文件上传大小 或 选择其他参数
         nginx.ingress.kubernetes.io/proxy-body-size: "0"
       labels:
         name: nginx-ingress
     spec:
       ingressClassName: nginx # 通过 kubectl get ingressclass 查看
       rules:
       - host: nginx.example.com # 修改为自己的对外域名
         http:
           paths:
           - backend:
               service:
                 name: nginx-service # Nginx Serice 名称
                 port:
                   number: 80 # Nginx 端口
             path: /
             pathType: Prefix
                 
       # 对外域名证书配置
       tls:
         - hosts:
           - nginx.example.com
           secretName: nginx-tls
     EOF
     ```

3. 访问域名
