VMware SIG Deep Dive into Kubernetes Scheduling Performance and high availability options for vSphere Steve Wong, Michael Gasch KubeCon North America December 13, 2018 2 Open Source Community Relations options, for both control plane and worker nodes. 2 levels of scheduling and resource management are active. Currently no automatic scheduling integration occurs, that is, Kubernetes is not aware of the distribution running on the vSphere stack. Agenda 4 Kubernetes default scheduling How it works Utilizing Zones to improve scheduling Using vSphere tags to define regions and zones – add cloud provider
