We are using a full CI/CD Rancher/Kubernetes stack.
Organization
We where using local volumes at first but we had to become HA and then we had to adopt a dedicated system. We tried longhorn and migrated to OpenEBS. We lost a node (bare metal) recently which was used as a cStor blockdevice, the replication seemed to work as we didn't loose any data ;)
