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
