SE Radio 649: Lukas Gentele on Kubernetes vClusters

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.
