升级Kubernetes版本从1.20.x升级到1.21.x

你好 ，

我在Nutanix上有一个Kubernetes群集，其中有1个主节点和2个工作节点（test Env）。所有节点的kubernetes版本为1.20.x.。我想将所有节点kubernetes版本更新为1.21.x。没有在其上运行的应用程序/服务的停机时间。

我已经在Nutanix指南中看到，这是升级Kubernetes版本的简单步骤，但它说应用程序可能有停机时间。

将Kubernetes版本从1.20.x升级到1.21.x的任何想法和输入而无需应用程序。

Hello ,<\/p>

\u00a0<\/p>

I have a kubernetes Cluster on Nutanix with 1 Master Node and 2 Worker Nodes(Test ENV). All the Nodes have Kubernetes version of 1.20.x. I want to Update the all the Nodes kubernetes version to 1.21.x. without the Downtime of application\/services running on it.\u00a0<\/p>

\u00a0<\/p>

I have Seen in Nutanix guide which is easy step to upgrade kubernetes version but it says application may have downtime.<\/p>

\u00a0<\/p>

Any Ideas and Inputs to upgrade Kubernetes version from 1.20.x to 1.21.x withoutdown of apps.<\/p>","quoteUsername":"ASHISHREDDY","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

嗨，阿什什，

您在YouTube视频中留下的评论中得到了答案。

使用单个节点控制平面，停机时间的概率高于三个节点控制平面。虽然单个控制平面节点正在升级，但不接受向群集的新请求，并且如果一个工人节点在升级此过程时会失败，则在该工人上运行的复制品直到控制平面才会重新启动回来了。

Hi Ashish,<\/p>

You got the answer in the comments you left in the YouTube video.<\/p><\/oembed>

\u00a0<\/p>

With a single node control plane, the probability of having downtime is higher than with a three nodes control plane. While the single control plane node is being upgraded, new requests to the clusters won't be accepted and in the event of one of the worker nodes failing while upgrading this, the replicas running on that worker won't be restarted until the control plane is back.<\/p><\/blockquote>","quoteUsername":"JoseNutanix","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

理解。我看不到从PrismCentra（Karbon UI）扩展主节点的选项。是否可以为现有群集添加另一个控制平面？

即使在具有2个主节点和2个工作人员节点的群集之后。当我单击升级Kubernetes版本时，（一个棱镜UI）过程如何在后面？

  1. 它会升级大师节点帕拉利还是一个接一个的？工人节点相同的情况？
  2. 有没有办法监视升级过程？

Understood. I dont see an option to scale master node from prismcentra(karbon UI). Is it possible to add One more control plane for the existing Cluster??<\/p>

\u00a0<\/p>

Even after Having the cluster with 2 master Nodes and 2 worker nodes. When I click on upgrade kubernetes version to 1.21.x. (one Prism UI) How process works behind ??<\/p>

\u00a0<\/p>

  1. Does it upgrade master nodes paralelly or one after the other? same case for worker nodes ?<\/li>\t
  2. Is there a way to monitor upgrade process ??<\/li><\/ol>

是的我明白。在PrismCentra（Karbon UI）中缩放主节点没有任何选择。我们可以在当前群集中添加一个控制层吗？
