When using addressability.external.method=Ingress the solr operator will create and configure an Ingress object.
Currently there is no way to configure additional annotations which are added to the created Ingress object.

This would be especially useful to enable features like passthrough or re-encrypt.

E.g. when using OKD route.openshift.io/termination: passthrough it is possible to passthrough the traffic to the already encrypted Solr endpoint.
