If you enable basic auth for your SolrCloud cluster, then you need to point
the Prometheus exporter at the basic auth secret;
refer to [Prometheus Exporter with Basic
Auth](../solr-prometheus-exporter/README.md#prometheus-exporter-with-basic-auth)

+## Various Runtime Parameters
+
+There are various runtime parameters that allow you to customize the running
of your Solr Cloud via the Solr Operator.
+
+### Time to wait for Solr to be killed gracefully
+
+The Solr Operator manages the Solr StatefulSet in a way that when a Solr pod
needs to be stopped, or deleted, Kubernetes and Solr are on the same page for
how long to wait for the process to die gracefully.
+
+The default time given is 60 seconds, before Solr or Kubernetes tries to
forcefully stop the Solr process.
+You can override this default with the field:
+
+```yaml
+spec:
+ ...
+ customSolrKubeOptions:
+ podOptions:
+ terminationGracePeriodSeconds: 120
Review comment:
This is a setting that users can set on pods, we merely forward this
information to the pod. There is no k8s source of truth other than the value
that each pod has. The default, set by the Solr Operator is 60 seconds.
Also I think the default value (for the pod) is different based on the
kubernetes distribution you use, but we shouldn't be relying on a default that
has nothing to do with Solr.
