Tanzu Kubernetes releases provide the Kubernetes software distribution for TKG cluster nodes running on Supervisor. Tanzu Kubernetes releases are distributed by VMware as virtual machine templates which you synchronize with Supervisor using a vCenter Content Library.

Using Tanzu Kubernetes Releases with TKG Clusters on Supervisor A Tanzu Kubernetes release provides the Kubernetes software distribution signed and supported by VMware for use with TKG clusters on Supervisor. The TKr format is updated for TKG to support packages and multiple operating systems.
Required Role Permissions for Administering Content Libraries Several vSphere role permissions are required for administering content libraries. If you are not using the vSphere Administrator role, refer to the list of permissions as needed.
Create a Subscribed Content Library To provision TKG clusters on Supervisor, you can create a subscribed content library and synchronize Tanzu Kubernetes releases. A subscribed content library lets you automate the distribution of TKRs and stay current with the latest releases.
Create a Local Content Library (for Air-Gapped Cluster Provisioning) To provision TKG clusters on Supervisor, you can create a local content library and import Tanzu Kubernetes releases. The typical use case for a local content library is internet-restricted environments (air-gapped).
Enable Publishing of a Local Content Library You can create a local content library and enable publication, allowing other content libraries to subscribe. This approach lets you control the Tanzu Kubernetes release images that are available for use, while providing TKG cluster operators with a subscription-style TKR service.
Edit an Existing Content Library The TKR content library you use for TKG clusters is not scoped to individual vSphere Namespaces. The same TKR content library is used for all vSphere Namespaces on a Supervisor instance. For this reason, changing the TKR content library is only allowed at the Supervisor level.
Migrate TKRs to a New Content Library If the TKR content library reaches capacity, you can migrate to a new content library with more storage capacity.
