<p>You can leverage the Operator to create these databases on Kubernetes.</p>
<p><strong>Operators</strong> will manage and create the database for you.</p>
<p><strong>Elasticsearch</strong> - <a href="https://www.elastic.co/downloads/elastic-cloud-kubernetes" rel="nofollow noreferrer">https://www.elastic.co/downloads/elastic-cloud-kubernetes</a></p>
<p><strong>Cassandra</strong> - <a href="https://github.com/instaclustr/cassandra-operator" rel="nofollow noreferrer">https://github.com/instaclustr/cassandra-operator</a></p>
<p><strong>Janusgraph</strong>  - <a href="https://github.com/IBM/janusgraph-operator" rel="nofollow noreferrer">https://github.com/IBM/janusgraph-operator</a></p>
<p>You can also leverage the helm chart available to setup database, mostly operators have helm chart for easy setup.</p>
<p>If you don't want to go with an operator you can directly install the helm also which will create the <strong>Deployment</strong>, <strong>POD</strong>, <strong>services</strong> for you with <strong>PVC</strong> and other required objects. The best practice will be to go with the <strong>operator</strong>.</p>
