无法部署Kubernetes群集（无法部署NTNX DVP）

你好，

我正在尝试通过部署开发集群来探索Kubernetes。但是它仅停留在8％，并最终在通知中失败（内部错误：未能部署NTNX DVP）。

这是我的细节

  • 段192.168.2.x，用于客座VM，PC，AOS和AHV。
  • 段192.168.3.x，用于kubernetes群集本身（启用DHCP）

每个细分市场都可以互相ping，所有这些段都可以访问Internet。

这是临时部署Karbon VM的细节（部署失败后，VM自动删除）

我一直在阅读某人发布了类似于我的问题，并且由于VM以前无法访问Internet而解决。但是我的能够访问Internet，PC和Internal Nutanix。

也许有人可以启发我我做错了什么？

- 可拉动最新的码头图像
- 可与Ping Prism Central（192.168.2.11）
- ping CVM（192.168.2.2）
- 可访问互联网
部署集群卡在8％
删除故障部署后的VM
通知内部错误：无法部署NTNX DVP

Hi,<\/p>

No, you don\u2019t need to configure them in your router, they are internal to Kubernetes. The reason of asking for them was to check you weren\u2019t using the VM or K8s segment as pod or service ranges.\u00a0<\/p>

At this point I\u2019d suggest you open a case with support, it\u2019s going to be faster than trying to work out here what\u2019s going on that is making your deployment to fail.<\/p>

Hi,<\/p>

I\u2019m trying to explore\u00a0kubernetes by deploying Development Cluster. But it only stuck at 8% and eventually failed with notification (Internal Error : Failed to deploy ntnx dvp).<\/p>

Here is my detail<\/p>

  • Segment 192.168.2.x for Guest VM,PC,AOS and AHV.<\/li>\t
  • Segment 192.168.3.x for Kubernetes cluster itself (DHCP Enabled)<\/li><\/ul>

    Each segment can ping each other and all those segments are able to access the internet.<\/p>

    Here is the detail of the temporary deployed Karbon VM (After failed deploying, the VM got deleted automatically)<\/p>

    I\u2019ve been reading someone posted same problem like mine, and it solved because of the VM previously unable to access the internet. But mine is able to access internet, PC and the Internal Nutanix.<\/p>

    Perhaps someone can enlighten me what did i do wrong?<\/p>

只需添加一些信息，我才意识到，当我想部署karbon群集时，我需要添加数据服务IP地址。如何启用它？由于我的群集外面没有任何外部存储空间。我不需要将外部存储数组作为数据服务IP添加到我的群集中吗？

Just adding some information, I just realized that when i want to deploy Karbon Cluster, i need to add the Data Services IP Address. How to enable it? Since i have no any external storage outside from my Cluster. I don't need external storage array to be added as a Data Services IP to my cluster?<\/p>","quoteUsername":"KarangDika","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

登录您的群集上的棱镜元素。单击位于左上角的群集名称，并设置ISCSI数据服务IP，如果未定义。

Log in to the Prism Element on your cluster. Click on the cluster name located in the top left corner and set\u00a0ISCSI Data Services IP if it\u2019s not defined.<\/p>

是的，我知道如何启用数据服务。但是我想问的是，这是什么数据服务？它就像我集群外的外部存储阵列吗？像Rubrick，Veeam，纯存储等？如果是这样，我将无法启用它，因为我没有。或者，如果我需要在群集内部创建的VM，那么VM的细节是什么？

Yeah i know how to enable the Data Services. But what i want to ask is, what is this Data Services? Is it like an external storage array outside of my cluster? Like rubrick, Veeam, pure storage, etc? If that's the case, i wont be able to enable it since i dont have any. Or if its a VM that i need to create first inside the cluster, what is the detail of the vm?<\/p>","quoteUsername":"KarangDika","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

这是可以将CVM从Nutanix群集提供的ISCSI存储连接到VM或容器的能力。如果K8S，您将使用此数据服务连接PVS。

It\u2019s an ability to connect iscsi storage served by CVMs from your nutanix cluster to VMs, or containers. In case of k8s you will connect PVs using this data services.\u00a0<\/p>","quoteUsername":"mikkisse","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

谢谢你回答我的问题。因此，最终我现在无法部署Kubernetes群集，因为我的Nutanix群集外面没有任何外部ISCSI存储阵列？

Thank you for answering my question. So eventually i can\u2019t deploy Kubernetes cluster right now since i dont have any external iscsi storage array outside from my nutanix cluster?<\/p>","quoteUsername":"KarangDika","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

不，您的Nutanix群集将像ISCSI阵列一样。对于此功能，您需要设置ISCSI数据服务IP。阅读此先决条件：在启用和部署Karbon之前，满足指示的要求

我设置了数据服务IP，如下所示。我将未使用的IP在该细分市场上作为数据服务IP。

数据服务IP

当我部署Kubernetes群集时，它失败了，但是工人VM等VM和Master VM已创建如下所示

KBS VM
这就是ISCSI VG
这是部署KBS群集时的故障注释

I\u2019ve set the Data Services IP like shown below. I take unused IP on that segment to be as Data Services IP.<\/p>

你好 @karangdika您可以共享用于POD和服务网络的IP子网吗？

你好 @karangdika您可以共享用于POD和服务网络的IP子网吗？

嗨，何塞，

我有192.168.2.x段，用于我们当前的客人VM，CVM和主机，PE和PC

我有192.168.3.x的kbs群集，并从棱镜中启用了DHCP。

虽然我使用的网络吊舱使用了Prism Central的默认一个建议

网络提供者：法兰绒

POD：172.20.0.0/16

服务：172.19.0.0/16

我还没有在路由器上设置此网络并切换。我需要先在路由器上设置此网络吗？还是我只是将其更改为当前的2.x或3.x？

抱歉，如果我犯了一个愚蠢的错误。

谢谢你。

Hi\u00a0@KarangDika<\/user-mention>\u00a0 Can you share what IP subnets are you configuring for the pod and service networks?<\/p>\t<\/div><\/content-quote>

Hi Jose,<\/p>

\u00a0<\/p>

I have 192.168.2.x segment for our current Guest VMs, CVMs and Hosts, PE and also PC<\/p>

I have 192.168.3.x segment for my KBs cluster with DHCP Enabled from PRISM.<\/p>

\u00a0<\/p>

While the network pod i use default one from Prism Central that suggested me<\/p>

Net Provider : Flannel<\/p>

Pod : 172.20.0.0\/16<\/p>

Service : 172.19.0.0\/16<\/p>

\u00a0<\/p>

I havent setup this network on my router and switch. Do i need to setup this network on my router first? Or i just change it into my current segment 2.x or 3.x?<\/p>

\u00a0<\/p>

Sorry if there is a silly mistake that i did.<\/p>

\u00a0<\/p>

Thank you.<\/p>","quoteUsername":"KarangDika","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

你好，

不，您无需在路由器中配置它们，它们是Kubernetes的内部。要求他们的原因是检查您不使用VM或K8S段作为POD或服务范围。

在这一点上，我建议您打开一个支持支持的案例，这要比试图在这里进行的事情要快，这使您的部署失败。

问候，

何塞

啊，我明白了。因此，从整个设置中，我的KBS应该正常部署正确吗？但是有些问题阻止了它。

好吧，谢谢你 @Josenutanix那我会打开票。

Ahh i see. So from the whole settings, my KBs should be deployed normally right? But something wrong that prevent it.<\/p>
