SE Radio 649: Lukas Gentele on Kubernetes vClusters

Author: team@se-radio.net (SE-Radio Team) January 3, 2025 Duration: 58:14

Lukas Gentele, CEO of Loft Labs, joins host Robert Blumen for a discussion of kubernetes vclusters (virtual clusters). A vcluster is a kubernetes cluster that runs kubernetes application on a host kubernetes cluster. The conversation covers: vcluster basics; sharing models; what is owned by the vcluster and what is shared with the host; attached nodes versus shared nodes; the primary use case: multi-tenancy vcluster per tenant; alternatives - namespace per tenant, full cluster per tenant; trade-offs - isolation; less resource use; spin up time; scalability; how many clusters and how many vclusters should an org have? Deployment models for vclusters - helm chart with standard resources; vcluster operator; persistent storage models for vclusters; vcluster snapshotting, recovery, and migration. how many vclusters can run on a cluster? ingress, TLS and DNS.
