You import the two Kubernetes example manifests into one design, add the Secret that holds the database password, and add the PersistentVolumes that the claims bind to. Stateless Pods can be replaced at any moment; a database cannot lose its files when that happens. This tutorial shows how Kubernetes separates the data from the Pod, and exactly which pieces a deploy creates and an undeploy removes.</p>/kanvas/tutorials/kubernetes/deploy-apache-cassandra-with-statefulset/Mon, 01 Jan 0001 00:00:00 +0000/kanvas/tutorials/kubernetes/deploy-apache-cassandra-with-statefulset/<p>In this tutorial you deploy Apache Cassandra as a three-node ring. A Deployment treats its Pods as interchangeable; Cassandra cannot, because each node owns part of the data and other nodes must find it at a known address. A StatefulSet gives every replica a fixed ordinal, a fixed DNS name, and its own volume, and starts the replicas one at a time. You import the Kubernetes example manifests into a Kanvas design, adapt them to your cluster, deploy, and watch the ring form.</p>
