The Solr PMC is pleased to announce the release of the Apache Solr Operator v0.8.0

The Solr Operator is the official and recommended way of managing your Solr ecosystem on Kubernetes.

The Solr Operator v0.8.0 is available for immediate download at: https://solr.apache.org/operator/artifacts.html

Solr Operator v0.8.0 Release Highlights:

The minimum supported version of Solr has been set to Solr 8.11
The minimum Kubernetes version supported is now v1.22
Managed scale up and scale down are now supported for SolrClouds.
- By default, when scaling down a SolrCloud, replicas will be migrated off Pods before they are deleted.
- By default, when scaling up a SolrCloud, replicas will be balanced across all Pods after the SolrCloud has been scaled up. (Only supported for Solr 9.3+)
SSL bugs with Solr 9 have been fixed, and v0.8.0 will successfully support SSL for Solr 8.11 and 9.4+
Solr 8.11 features are now supported by default, such as maxBooleanClauses, metrics disabling, health endpoint for readinessCheck
Keystore/Truststore passwords can be explicitly set in the SolrCloud CRD for mountedDir SSL. This enables the use of the CertManager CSI Driver with Solr.
Rolling Updates for SolrClouds using ephemeral storage are now safer and replicas are balanced at the end of the operation to ensure optimal resource utilization.
- Replica balancing is only supported when Solr 9.3+ is used.
