环境信息：
namespace为 tkc-cluster, Tanzu Kubernetes Cluster为：tkc-guest-cluster
第一步：ContentLabrary
在vSphere Web Client中看到为Tanzu Kubernetes Cluster创建的ContentLabrary中已经自动下载了 v1.17.7版本，于是将已部署的Tanzu Kubernetes Cluster进行升级。
第二步：确定当前版本
Tanzu Kubernetes集群当前版本为 1.16.8
$ kubectl config use-context tkc-guest-cluster # 切换到 tanzu kubernetes cluster
Switched to context "tkc-guest-cluster".
$ kubectl get node NAME STATUS ROLES AGE VERSION tkc-guest-cluster-control-plane-6cfsf Ready master 10d v1.16.8+vmware.1 tkc-guest-cluster-control-plane-drlqp Ready master 10d v1.16.8+vmware.1 tkc-guest-cluster-control-plane-wmn2s Ready master 10d v1.16.8+vmware.1 tkc-guest-cluster-workers-8k9c8-5576b69b67-rcsvd Ready <none> 3d2h v1.16.8+vmware.1 tkc-guest-cluster-workers-8k9c8-5576b69b67-s7hch Ready <none> 10d v1.16.8+vmware.1 tkc-guest-cluster-workers-8k9c8-5576b69b67-sb6ss Ready <none> 3d2h v1.16.8+vmware.1 tkc-guest-cluster-workers-8k9c8-5576b69b67-tnxn2 Ready <none> 10d v1.16.8+vmware.1 tkc-guest-cluster-workers-8k9c8-5576b69b67-vxgt9 Ready <none> 10d v1.16.8+vmware.1
第三步：执行版本升级
注意需要登录suppervisor cluster才能执行升级命令
$ read -r -d '' PATCH <<'EOF' spec: distribution: fullVersion: null version: v1.17.7 EOF
$ kubectl patch --type=merge tanzukubernetescluster tkc-guest-cluster --patch "$PATCH" # 需要切换到supersivor cluster
tanzukubernetescluster.run.tanzu.vmware.com/tkc-guest-cluster patched
第四步：查看升级进度
默认以滚动的方式进行升级。
$ kubectl config use-context tkc-guest-cluster # 切换到 tanzu kubernetes cluster Switched to context "tkc-guest-cluster". $ kubectl get node NAME STATUS ROLES AGE VERSION tkc-guest-cluster-control-plane-6cfsf-7138032 NotReady master 8m55s v1.17.7+vmware.1 tkc-guest-cluster-control-plane-drlqp Ready master 10d v1.16.8+vmware.1 tkc-guest-cluster-control-plane-drlqp-7138032 Ready master 2m36s v1.17.7+vmware.1 tkc-guest-cluster-control-plane-wmn2s Ready master 10d v1.16.8+vmware.1 tkc-guest-cluster-workers-8k9c8-5576b69b67-rcsvd Ready <none> 3d3h v1.16.8+vmware.1 tkc-guest-cluster-workers-8k9c8-5576b69b67-s7hch Ready <none> 10d v1.16.8+vmware.1 tkc-guest-cluster-workers-8k9c8-5576b69b67-sb6ss Ready <none> 3d3h v1.16.8+vmware.1 tkc-guest-cluster-workers-8k9c8-5576b69b67-tnxn2 Ready <none> 10d v1.16.8+vmware.1 tkc-guest-cluster-workers-8k9c8-5576b69b67-vxgt9 NotReady <none> 10d v1.16.8+vmware.1
