The solr-operator supports the full lifecycle of standard aliases. Here is an example pointing an alias to 2 collections
apiVersion: solr.bloomberg.com/v1beta1
kind: SolrCollectionAlias
metadata:
name: collection-alias-example
spec:
solrCloud: example
aliasType: standard
collections:
- example-collection-1
- example-collection-2
Aliases can be useful when migrating from one collection to another without having to update application endpoint configurations.
Routed aliases are presently not supported
