Known Issues

Solr Cloud

• You may be seeing timeouts in your Solr logs after a rolling update. This can be caused by DNS caching in CoreDNS (the default DNS for Kubernetes). This can be fixed by reducing the kubernetes cache TTL to 5-10 seconds. Please refer to this ticket for more information: https://github.com/kubernetes/kubernetes/issues/92559
  Fix: In the kube-system namespace, there will be a ConfigMap with name coredns. It will contain a section:

  kubernetes cluster.local in-addr.arpa ip6.arpa {
   ...
   ttl 30
  ...
  }
  

  Edit the ttl value to be 5, CoreDNS will automatically see a change in the configMap and reload it.
