VMware vSphere with Kubernetes on VxRail

VMware vSphere with Kubernetes on VxRail

  • If you require workload management using Kubernetes, you can configure a VxRail cluster as a supervisor cluster for Kubernetes.

    Kubernetes is a portable, extensible, API-driven platform for the management of containerized workload and services. The VMware Tanzu feature enables the conversion of a VxRail cluster with a VMware vSphere foundation into a platform for running Kubernetes workloads inside dedicated resource pools. A VxRail cluster that is enabled for VMware vSphere with Tanzu is called a Supervisor cluster.

    When a VxRail cluster is enabled for vSphere with Kubernetes, the following six services are configured to support VMware vSphere with Tanzu:
    • VMware vSphere Pod Service
    • Registry Service
    • Storage Service
    • Network Service
    • Virtual Machine Service
    • Tanzu Kubernetes Grid Service for VMware vSphere

    As a VxRail administrator using VMware vSphere management capabilities, you can create name spaces on the Supervisor Cluster, and configure them with a specified amount of memory, CPU, and storage. Within the name spaces, you can run containerized workloads on the same platform with shared resource pools.
    • This feature requires each VxRail node that is part of the Supervisor cluster to be configured with a VMware vSphere Enterprise Plus license with an add-on license for Kubernetes.
    • This feature requires port groups to be configured on the VxRail cluster virtual-distributed-switch to support workload networks. These networks provide connectivity to the cluster nodes and the three Kubernetes control plane VMs. Each Supervisor Cluster must have one primary workload network.
    • A virtual load balancer that is supported for vSphere must also be configured on the VxRail cluster to enable connectivity from client network to workloads running in the name spaces.
    • The workload networks require reserved IP addresses to enable connectivity for the control plane VMs and the load balancer.

    For complete details on enabling a VxRail cluster to support VMware vSphere with Tanzu, see the vSphere with Tanzu Configuration and Management Guide.
