Automating Stateful Applications with Kubernetes Operators

on YouTube ↗53m

" summary

Operators encode operational knowledge into Kubernetes controllers so the cluster can install, scale, backup and upgrade stateful services without human intervention. Demonstrations use the Operator SDK 0.5.0 to scaffold CRDs and controllers, the Operator Lifecycle Manager and Operator Hub on OpenShift to install an operator, and an operator that performs a backup-before-upgrade reconciliation step. The demo deploys a 3-node Kafka cluster with Zookeeper, creates topics via the operator API, and shows the workflow succeeds end-to-end.
