Issue with adding a second or third cluster

[cbluth]

Hello, I seemingly have added my first k8s cluster without issue, I have explained the process I used to add the first cluster here: #46 (comment)

My issue is that when I want to add another cluster, my dashboards end up looking like this:

I see this:

kubernetes-app/dist/components/clusters/clusterConfig.ts

Line 481 in ddf616e

replacement: kubernetes.default.svc:443

Does this mean that the dashboard can only connect to the cluster that it is running in? or can it still connect to clusters outside the current cluster?

I think I found the solution to my issue:

1. make sure prometheus-server is installed on each cluster.
2. add config for prometheus federation, see here: https://prometheus.io/docs/prometheus/latest/federation/
   my config looks like this:

    - job_name: federate
      scrape_interval: 15s
      honor_labels: true
      metrics_path: '/federate'
      params:
        'match[]':
          - '{job="prometheus"}'
          - '{job=~"^kubernetes.+"}'
          - '{__name__=~"job:.*"}'
      static_configs:
        - targets:
          - 'ip-of-other-prometheus-server:9090'
