You Have Stateful Apps - What if Kubernetes Would Also Run Your Storage?
summary
Shows container-native storage built from GlusterFS and gluster-kubernetes running on OpenShift/Kubernetes, using the heketi REST API and StorageClass for dynamic provisioning. Demonstration deploys a GlusterFS on OpenShift cluster across three nodes, creates volumes via a storage class and a PVC, and mounts them into a MySQL pod; lifecycle actions (create, bind, delete) work end-to-end. Key numbers and choices: replica 3 per volume, three nodes minimum, supports file (and newer S3/ISCSI) backends, and uses secrets for secured heketi access.
