Kibana with basePath login redirect loop on GCP

[uncl3mar1k (Marian)]

On a regular GKE private cluster I

1. Installed ECK (kubectl apply -f https://download.elastic.co/downloads/eck/1.3.1/all-in-one.yaml)
2. Installed Elasticsearch and Kibana:

    apiVersion: v1

    kind: Namespace

    metadata:

      name: elastic

      labels:

        name: elastic

        istio-injection: enabled

    ---

    apiVersion: elasticsearch.k8s.elastic.co/v1

    kind: Elasticsearch

    metadata:

      name: monitoring

      namespace: elastic

    spec:

      version: 7.10.1

      http:

        tls: 

          selfSignedCertificate:

            disabled: true

      nodeSets:

      - name: default

        count: 1

        config:

          node.store.allow_mmap: false

    ---

    apiVersion: kibana.k8s.elastic.co/v1

    kind: Kibana

    metadata:

      name: monitoring

      namespace: elastic

    spec:

      version: 7.10.1

      count: 1

      elasticsearchRef:

        name: monitoring

      # config:

      #   xpack.security.enabled: false

      http:

        tls: 

          selfSignedCertificate:

            disabled: true

      podTemplate:

        spec:

          containers:

          - name: kibana

            env:

            - name: SERVER_BASEPATH

              value: "/kibana"

3. port-forward: kubectl -n elastic port-forward service/monitoring-kb-http 5601

Web preview in the browser on port 5061 returns ERR_TOO_MANY_REDIRECTS, while the url is https://....cloudshell.dev/kibana/login?next=%2Fkibana%2Fkibana%2Flogin%3Fnext%3D%252Fkibana%252Fkibana%252Flogin%253Fnext%253D%25252Fkibana%25252Fkibana%25252Flogin%25253Fnext%25253D%2525252Fkibana%2525252Fkibana%2525252Flogin%2525253Fnext%2525253D%252525252Fkibana%252525252Fkibana%252525252Flogin%252525253Fnext%252525253D%25252525252Fkibana%25252525252Fkibana%25252525252Flogin%25252525253Fnext... (and so on)
(same issue when I expose Kibana service with istio)

Without the basePath setting, everything works fine. But I want to access Kibana not in the root path so I need the basePath setting to be working.

Any thoughts on this pls.

Can you try deleting the sid cookie in your browser, or loading it in another browser or incognito window and see if you still see that happen? The basePath setting just re-writes the URLs, something still has to serve up the site at that path though.

Also check : https://github.com/elastic/kibana/issues/36825
