Deploy Clusters with Different Kubernetes Versions ¶

Tanzu Community Edition manages Kubernetes versions with Tanzu Kubernetes release (TKr) objects.

The following steps describe how to view available TKr versions and use them when creating a workload cluster.

1. List the available TKrs.

   tanzu kubernetes-release
   

   Ouptut:

   NAME                                  VERSION                             COMPATIBLE  ACTIVE  UPDATES AVAILABLE
   v1.20.14---vmware.1-tkg.4-tf-v0.11.2  v1.20.14+vmware.1-tkg.4-tf-v0.11.2  True        True    True
   v1.21.8---vmware.1-tkg.4-tf-v0.11.2   v1.21.8+vmware.1-tkg.4-tf-v0.11.2   True        True    True
   v1.22.5---vmware.1-tkg.3-tf-v0.11.2   v1.22.5+vmware.1-tkg.3-tf-v0.11.2   True        True    False
   

2. When creating a cluster, specify the TKr using the --tkr flag.

   tanzu cluster create --tkr v1.21.8---vmware.1-tkg.4-tf-v0.11.2
   

   This will deploy the TKr with Kubernetes v1.21.8. This cluster will be upgradable to the TKr featuring Kubernetes v1.22.5.
