ingress doesn't return static resources

[survivant]

I wanted to add Ingress for kafka-ui but it's not working (but working fine with the nodePort. What is missing to get it to work with Ingress ?

http://10.1.34.6/kafka-ui

here my config

kafka-ui:
  enabled: true
  service:
    type: NodePort
    nodePort: 32002

  envs:
    config:
      KAFKA_CLUSTERS_0_NAME: local
      KAFKA_CLUSTERS_0_BOOTSTRAPSERVERS: kafka-cp-kafka:9092
      KAFKA_CLUSTERS_0_ZOOKEEPER: kafka-cp-zookeeper:2181
      KAFKA_CLUSTERS_0_SCHEMAREGISTRY: http://kafka-cp-schema-registry:8081
      KAFKA_CLUSTERS_0_KAFKACONNECT_0_ADDRESS: http://kafka-cp-kafka-connect:8083

  ingress:
    annotations:
      nginx.ingress.kubernetes.io/rewrite-target: /$2
      nginx.ingress.kubernetes.io/ssl-redirect: "false"
    enabled: true
    hosts:
    - host: ""
      paths:
      - /kafka-ui(/|$)(.*)

here the ingress generated

...
spec:
  rules:
  - http:
      paths:
      - backend:
          service:
            name: kafka-ui
            port:
              number: 80
        path: /kafka-ui(/|$)(.*)
        pathType: ImplementationSpecific

I can compare it with granafa
http://10.1.34.6/grafana redirect to http://10.1.34.6/grafana/login

....
spec:
  rules:
  - http:
      paths:
      - backend:
          service:
            name: monitoring-stack-grafana
            port:
              number: 80
        path: /grafana(/|$)(.*)
        pathType: Prefix

is it a resource mapping that is missing in Spring boot to handle that ?

Hi @survivant, thanks for opening this issue, we able to reproduce that behavior of the ingress and has looking for a solution, unfortunately, we cannot provide any workaround

@RustamGimadiev thanks for the feedback. the workaround that I use, if a nodePort for now.

Hi @RustamGimadiev

We are using AWS EKS, our ingress controller is aws-load-balancer-controller which does not support rewrite-target like nginx.ingress does.

We are doing path based fanout like foobaa.com/airflow foobaa.com/kafka foobaa.com/spark, however once I set ingress path to non-root path I can not reach the UI anymore.

Non-working configuration:

ingress:
  enabled: true
  hosts:
    - host:
      paths:
        - /kafkaui/*

Working configuration:

ingress:
  enabled: true
  hosts:
    - host:
      paths:
        - /*

Can you add capability of running on a non-root path either by default or by setting the base path in the configuration?

Thank you!

Hi, @survivant @andormarkus, now you can use kafka-ui with custom URI prefix, for that please use latest image tag, the example of use described in https://github.com/provectus/kafka-ui/blob/master/docker/kafka-ui-reverse-proxy.yaml
