kubernetes nginx 入口子路徑到子域重定向

Question

我正在嘗試實現以下 proxy_pass 設置，基本上其中一項服務是列出 subdomain.example.com/guacamole 但我想將其作為 subdomain.example.com 提供

    location / {
    proxy_pass http://guacamole:8080/guacamole/;
    proxy_buffering off;
    proxy_http_version 1.1;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection $http_connection;
    proxy_cookie_path /guacamole/ /;
    access_log off;
    # allow large uploads (default=1m)
    # 4096m = 4GByte
    client_max_body_size 4096m;
    }

下面是nginx入口

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: guacamole-ingress
  annotations:
    kubernetes.io/ingress.class: nginx
spec:
  tls:
  - hosts:
    - subdomain.example.com
  rules:
  - host: subdomain.example.com
    http:
      paths:
      - path: /guacamole
        backend:
          serviceName: service-guacamole-frontend
          servicePort: 8080

我嘗試使用nginx.ingress.kubernetes.io/rewrite-target: /但它沒有用。

Answer 1

更換path: /guacamole與path: /應該做的伎倆。

  rules:
  - host: subdomain.example.com
    http:
      paths:
      - path: /  # replace `/guacamole` with `/`
        backend:
          serviceName: service-guacamole-frontend
          servicePort: 8080

Answer 2

您應該使用app-root注釋。

來自 nginx-ingress 文檔：

如果Application Root暴露在不同的路徑，需要重定向，設置注解nginx.ingress.kubernetes.io/app-root重定向/請求。

嘗試使用：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: guacamole-ingress
  annotations:
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/app-root: /guacamole
spec:
  tls:
  - hosts:
    - subdomain.example.com
  rules:
  - host: subdomain.example.com
    http:
      paths:
      - path: /
        backend:
          serviceName: service-guacamole-frontend
          servicePort: 8080

在這里你可以找到另一個例子。
