Question

我有一个带有Ingress的k8s应用程序，我想使用它使用子域为其他应用程序提供服务。

这是我的完整配置：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: symfony-nginx
  namespace: default
  labels:
    app: symfony-nginx
spec:
  replicas: 1
  selector:
    matchLabels:
      app: symfony-nginx
  template:
    metadata:
      labels:
        app: symfony-nginx
    spec:
      volumes:
        - name: symfony-nginx
          configMap:
            name: symfony-nginx-configmap
      containers:
      - name: symfony-nginx
        image: nginx:latest
        imagePullPolicy: Always
        ports:
        - containerPort: 80
        volumeMounts:
        - mountPath: /etc/nginx/conf.d
          name: symfony-nginx
        resources:
          requests:
            memory: 32Mi
            cpu: 10m
          limits:
            memory: 64Mi
            cpu: 30m
        readinessProbe:
          httpGet:
            path: /nginx-health
            port: 80
          initialDelaySeconds: 15
          timeoutSeconds: 1
          periodSeconds: 10
        livenessProbe:
          httpGet:
            path: /nginx-health
            port: 80
          initialDelaySeconds: 15
          timeoutSeconds: 1
          periodSeconds: 10

我只收到'找不到“ GET / symfony”的路由” ，因为到达php-fpm的uri保留了'symfony'前缀。

我该如何责怪NGINX在'symfony'之后仅将uri的一部分发送到php-fpm？

[更新]

也许这是一个symfony应用程序问题，因为我在http://mydomanin.com/symfony上收到了index.php的响应，并带有'找不到“ GET / symfony”的路由” ？还是这是NGINX的责任？

谢谢，问候

Answer 1

最好的解决方案是为交响乐本身中的所有路由设置一个/symphony前缀。

另一种方法是在nginx上使用rewrite：

rewrite ^/symphony/(.*)$ /$1 last;

但是要当心后果！ Symphony将返回带有'/myImage.jpg'的图像URL，与js / css / ...相同。链接将为”，依此类推，这些页面将不会映射到您的应用程序。

最后我找到了解决方案。

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: symfony-nginx-ingress
spec:
  rules:
  - http:
      paths:
      - path: /symfony
        backend:
          serviceName: symfony-nginx-np
          servicePort: 80

此Ingress配置仅与/ symfony路由匹配，因此要完成此配置，还需要添加/ symfony / * ...在我看来，这不是很优雅...
