[bitnami/solr] solr-exporter does not start

[muffl0n]

Name and Version

bitnami/solr 9.5.0

What architecture are you using?

amd64

What steps will reproduce the bug?

1. Install solr chart
2. Do not adjust the resources for the solr-exporter

What is the expected behavior?

solr-exporter should start correctly and export metrics

What do you see instead?

solr-exporter does nothing after logging Beginning metrics collection. There's no further error message and no obvious reason why it does not work.

Additional information

The resources configured by default are just too small. Default is nano which is

  "nano" (dict 
      "requests" (dict "cpu" "100m" "memory" "128Mi" "ephemeral-storage" "50Mi")
      "limits" (dict "cpu" "150m" "memory" "192Mi" "ephemeral-storage" "2Gi")
   )

We experienced, that solr-exporter needs around 600-1000MB memory. We have 8 collections in Solr with around 90GB of data so this is probably pretty low compared to other installations.

For the time being we set resourcesPreset to none which works but surely isn't the proper solution. Any other preset would not fit as well. medium might be okay for the memory, but surely not for CPU:

  "medium" (dict 
      "requests" (dict "cpu" "500m" "memory" "1024Mi" "ephemeral-storage" "50Mi")
      "limits" (dict "cpu" "750m" "memory" "1536Mi" "ephemeral-storage" "2Gi")
   )

So one has to configure custom values.
