Solr Operator

The Solr Operator is the official way of managing an Apache Solr ecosystem within Kubernetes. It is built on top of the Kube Builder framework. Please visit the official site for more information.

The project is Production Ready, and has been successfully used to manage production SolrClouds for some of the largest users of Solr.

The API Version is still beta (v1beta1), and minor versions can have backwards-incompatible API changes. However, the Solr Operator will always have upgrade paths that are backwards-compatible. Please check the version compatibility and upgrade/deprecation notes for more information.

If you run into issues using the Solr Operator, please:

• Reference the version compatibility and upgrade/deprecation notes provided below
• Create a GitHub Issue in this repo, describing your problem with as much detail as possible
• Reach out on our Slack channel!

Join us on the #solr-operator channel in the official Kubernetes slack workspace.
