This section describes how to provision Tanzu Kubernetes clusters using the TKGS v1alpha2 API. What to read next Requirements for Using the TKGS v1alpha2 APITo use the Tanzu Kubernetes Grid Service v1alpha2 API for provisioning Tanzu Kubernetes clusters, adhere to the full list of requirements. TKGS v1alpha2 API for Provisioning Tanzu Kubernetes ClustersThe Tanzu Kubernetes Grid Service v1alpha2 API lets you declaratively provision Tanzu Kubernetes clusters. Refer to the list and description of all parameters and usage guidelines to create and customize your clusters. Example YAML for Provisioning Tanzu Kubernetes Clusters Using the TKGS v1alpha2 APIThe TKGS API provides intelligent defaults and an array of options for customizing Tanzu Kubernetes clusters. Refer to the examples to provision clusters of various types with different configurations and customizations to meet your needs. Updating a Tanzu Kubernetes Release After the Cluster Spec Is Converted to the TKGS v1alpha2 APIAfter a Tanzu Kubernetes cluster specification has been auto-converted to the v1alpha2 API format, to perform a rolling update of the Tanzu Kubernetes cluster, which is typically done by changing the Tanzu Kubernetes release version, you may need to do some pre-processing of the cluster spec to avoid errors. Configuring a Tanzu Kubernetes Cluster with a Routable Pod Network Using the v1alpha2 APIYou can configure a Tanzu Kubernetes cluster to use routable pod networking by specifying the antrea-nsx-routed as the CNI for your cluster. Configuration Parameters for the TKGS v1alpha2 APIYou can customize the Tanzu Kubernetes Grid Service with global settings for key features, including the container network interface (CNI), proxy server, and TLS certificates. Be aware of trade-offs and considerations when implementing global versus per-cluster functionality. Examples for Configuring the TKGS Instance Using the v1alpha2 APIRefer to the examples to customize the Tanzu Kubernetes Grid Service v1alpha2 API with global configuration settings for the container network interface, proxy server, and TLS certificates. Scale a Tanzu Kubernetes Cluster Using the TKGS v1alpha2 APIYou can scale a Tanzu Kubernetes cluster horizontally by changing the number of nodes or vertically by changing the virtual machine class hosting the nodes.
