You can create Kubernetes clusters of different node sizes from the existing organization VDC policies.
Kubernetes Container Clusters is the Container Service Extension plug-in for VMware Cloud Director. You can use the Kubernetes Container Clusters plug-in in the VMware Cloud Director Tenant Portal to deploy clusters with native and VMware Tanzu Kubernetes Grid Integrated Edition (TKGI) clusters. You can create Tanzu Kubernetes clusters without the Kubernetes Container Clusters plug-in.
When enabled on a vSphere cluster, VMware vSphere® with VMware Tanzu™ provides the capability to create upstream Kubernetes clusters in dedicated resource pools. For more information, see the vSphere with Kubernetes Configuration and Management guide in the vSphere documentation.
When a service provider creates a provider VDC Kubernetes policy and publishes the policy to an organization VDC, they create an organization VDC Kubernetes policy. You can use the Kubernetes Container Clusters plug-in to create Tanzu Kubernetes clusters by applying one of the organization VDC Kubernetes policies.
Kubernetes Runtime Options
- Tanzu Kubernetes clusters - You can use the vSphere Kubernetes runtime option to create vSphere with VMware Tanzu managed Tanzu Kubernetes clusters. This option offers more features, however, it might be more expensive. For more information, see the vSphere with Kubernetes Configuration and Management guide in the vSphere documentation.
- Native clusters - The Kubernetes Container Clusters plug-in manages the clusters with native Kubernetes runtime. These clusters are with reduced High Availability function with a single master node, they offer fewer persistent volume choices and no networking automation. However, they might come at a lower cost.
- TKGI clusters - VMware Tanzu Kubernetes Grid Integrated Edition is a purpose-built container solution to operationalize Kubernetes for multi-cloud enterprises and service providers. Some of its capabilities are high availability, auto-scaling, health-checks, as well as self-healing and rolling upgrades for Kubernetes clusters. For more information on TKGI clusters, see the VMware Tanzu Kubernetes Grid Integrated Edition documentation.
