Upgrading Kubernetes clusters components using CLI
Overview¤
This document is aimed to provide AUCloud tenancy administrators an overview on how to upgrade kubernetes components within VMware Cloud Director (VCD).
To see how to upgrade a Kubernetes cluster version please see here
Upgrading Tanzu Kubernetes components¤
Tanzu Kubernetes relies on components to communicate with VMware Cloud Director (VCD), these should be upgraded where possible to patch the provider.
To view the current versions of Tanzu Kubernetes for VCD and component versions and see the following link here
View component versions via GUI (vcd web)¤

View component versions via CLI¤
While connected to your Kubernetes cluster perform the following commands and verify the version
If you have multiple clusters you can specify individual config files within the command to save time --kubeconfig=< path to kubeconfig > after kubectl example of CAPVCD below.
#example using --kubeconfig
kubectl --kubeconfig=< path to kubeconfig > get deployment -n capvcd-system capvcd-controller-manager -o=jsonpath={.spec.template.spec.containers[*].image}
Cloud Provider for VCD (CAPVCD)¤
capvcd-system capvcd-controller-manager
kubectl get deployment -n capvcd-system capvcd-controller-manager -o=jsonpath={.spec.template.spec.containers[*].image}
#output
projects.registry.vmware.com/vmware-cloud-director/cluster-api-provider-cloud-director:1.0.0
Cluster API Provider (CPI)¤
kube-system vmware-cloud-director-ccm
kubectl get deployment -n kube-system vmware-cloud-director-ccm -o=jsonpath={.spec.template.spec.containers[*].image}
#output
projects.registry.vmware.com/vmware-cloud-director/cloud-provider-for-cloud-director:1.2.0
Container Storage interface driver (CSI)¤
kube-system csi-vcd-nodeplugin
kubectl get DaemonSet -n kube-system csi-vcd-nodeplugin -o=jsonpath={.spec.template.spec.containers[*].image}
#output
k8s.gcr.io/sig-storage/csi-node-driver-registrar:v2.2.0
projects.registry.vmware.com/vmware-cloud-director/cloud-director-named-disk-csi-driver:1.3.0
