Kubernetes nginx ingress rabbitmq management and kibana

问题

On my AKS cluster I have a Nginx ingress controller that I used to reverse proxy my kibana service running on the AKS. I want to however add another http services through the ingress, rabbitmq management console.

I'm unable to get both to work with the following configuration:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ingress-aegis
  namespace: dev
  annotations:
    kubernetes.io/ingress.class: nginx
    certmanager.k8s.io/cluster-issuer: letsencrypt-prod
    nginx.ingress.kubernetes.io/rewrite-target: /    
spec:
  tls:
  - hosts:
    - dev.endpoint.net
    secretName: dev-secret   
  rules:
  - host: dev.endpoint.net
    http:
      paths:
      - path: /
        backend:
          serviceName: kibana-kibana
          servicePort: 5601
      - path: /rabbit
        backend:
          serviceName: rabbitmq
          servicePort: 15672

The Kibana works fine at root however RabbitMQ fails to load with a 503 with any path except /. If RabbitMQ's path is / then it works fine but then Kibana won't run.

I assume this is because internally they are sitting on the root aka localhost:15672 so it redirects to / on dev.endpoint.net.

How do I have multiple services like Kibana and RabbitmQ running from one endpoint?

回答1:

What you need to do is set the basePath for kibana to /kibana

See the below url

https://www.elastic.co/guide/en/kibana/current/settings.html

You are looking to configure server.basePath to /kibana. Then this will sort the reverse proxying issues and you can keep the MQ one directly on root /

You can also set SERVER_BASEPATH environment variable in your kibana pod and it will automatically pick the base path from that variable

One idea would be to do host name based rules to switch backends. However, this would require a wildcard or SAN SSL certificate.

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ingress-aegis
  namespace: dev
  annotations:
    kubernetes.io/ingress.class: nginx
    certmanager.k8s.io/cluster-issuer: letsencrypt-prod
    nginx.ingress.kubernetes.io/rewrite-target: /    
spec:
  tls:
  - hosts:
    - dev.endpoint.net
    - rabbit.endpoint.net
    secretName: dev-secret   
  rules:
  - host: dev.endpoint.net
    http:
      paths:
      - path: /
        backend:
          serviceName: kibana-kibana
          servicePort: 5601
  - host: rabbit.endpoint.net
    http:
      paths:
      - path: /
        backend:
          serviceName: rabbitmq

For RabbitMQ Management UI via ingress, set the following in the rabbitmq.conf file (you can use configmaps and mount the file inside the pod)

management.path_prefix = /rabbit

In the Ingress set the following :

...
   path: /rabbit(/|$)(.*)
...

See : https://www.rabbitmq.com/management.html#path-prefix
