接下来,需要将ConfigMap与Ingress关联起来。

代码语言:javascript复制
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: example-ingress
  annotations:
    nginx.ingress.kubernetes.io/custom-http-errors: "404,500"
    nginx.ingress.kubernetes.io/configuration-snippet: |
      error_page 404 /custom_404.html;
      error_page 500 /custom_500.html;
spec:
  rules:
  - host: example.com
    http:
      paths:
      - path: /example
        pathType: Prefix
        backend:
          service:
            name: example-service
            port:
              number: 80

在上面的配置中,nginx.ingress.kubernetes.io/configuration-snippet注解用于指定在Nginx中使用自定义页面的配置。例如,上述配置指定了404和500错误代码的自定义页面,以及Nginx中的自定义页面路径。接下来,需要在ConfigMap中定义这些自定义页面。

代码语言:javascript复制
apiVersion: v1
kind: ConfigMap
metadata:
  name: custom-http-errors
data:
  custom_404.html: |
    <!DOCTYPE html>
    <html>
    <head>
        <title>404 Not Found</title>
    </head>
    <body>
        <h1>404 Not Found</h1>
        <p>The requested URL was not found on this server.</p>
    </body>
    </html>
  custom_500.html: |
    <!DOCTYPE html>
    <html>
    <head>
        <title>500 Internal Server Error</title>
    </head>
    <body>
        <h1>500 Internal Server Error</h1>
        <p>The server encountered an internal error or misconfiguration and was unable to complete your request.</p>
    </body>
    </html>

在上面的配置中,data字段定义了404和500错误代码的自定义页面。这些页面的内容以HTML格式提供,并且文件名必须与Nginx中使用的自定义页面路径相匹配。最后,需要将ConfigMap与Ingress关联起来。

代码语言:javascript复制
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: example-ingress
  annotations:
    nginx.ingress.kubernetes.io/custom-http-errors: "404,500"
    nginx.ingress.kubernetes.io/configuration-snippet: |
      error_page 404 /custom_404.html;
      error_page 500 /custom_500.html;
spec:
  rules:
  - host: example.com
    http:
      paths:
      - path: /example
        pathType: Prefix
        backend:
          service:
            name: example-service
            port:
              number: 80
  errorPages:
  - code: 404
    path: /custom_404.html
  - code: 500
    path: /custom_500.html

在上面的配置中,errorPages字段定义了404和500错误代码的自定义页面,并指定了页面的路径。这些页面路径必须与ConfigMap中定义的路径匹配。最后,应用配置即可,以便使这些配置生效。
