你好，

我正在尝试通过部署开发群集来探索Kubernetes。但它只粘在8％并最终失败了通知（内部错误：无法部署NTNX DVP）。

这是我的细节

  • SEGENT 192.168.2.x for Guest虚拟机，PC，AOS和AHV。
  • 段192.168.3。x for Kubernetes cluster本身(DHCP启用)

每个段都可以互相ping，并且所有这些段都能够访问互联网。

以下是临时部署的karbon vm的细节（在部署失败后，VM自动删除）

我已经看到有人张贴了类似我的问题，它解决了，因为VM之前无法访问互联网。但我的电脑可以接入互联网，PC和内部的Nutanix。

也许有人能告诉我，我做错了什么?

- 拉动最新的码头图像
- 坪棱镜中央（192.168.2.11）
- 适用于Ping CVM（192.168.2.2）
- 可访问互联网
部署群集粘在8％
失败部署后删除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？由于我的群集外部没有任何外部存储。我不需要将外部存储阵列添加到我的群集的数据服务IP中？

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"}}}">

登录到您集群中的Prism元素。单击位于左上角的集群名称，并设置ISCSI数据服务IP(如果没有定义的话)。

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。但我想问的是，什么是数据服务?它是不是像集群外的一个外部存储阵列?像rubrick, Veeam，纯存储等等?如果是这样的话，我将不能使它，因为我没有任何。或者如果它是一个虚拟机，我需要首先在集群中创建，虚拟机的细节是什么?

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"}}}">

它是将CVMS服务的iSCSI存储连接到VM或容器中的CVMS服务。如果是K8S，您将使用此数据服务连接PV。

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。所以最终我现在无法部署Kubernetes群集，因为我的Nutanix群集外部没有任何外部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阵列一样行动。对于此功能，您需要设置iSCSI数据服务IP。阅读此先决条件：在启用和部署卡片之前满足所示的要求

我已经设置了下面如下所示的数据服务IP。我在该分段上占用未使用的IP作为数据服务IP。

数据服务IP.

当我部署Kubernetes群集时，它失败，但工作人员VM，etcd VM和Master VM已经如下所示创建

KBS VMS.
这是iSCSI vg
这是部署KBS群集时的失败注意

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

And when i deployed the kubernetes cluster, it failed but the workers vm, etcd vm and master vm has been created like shown below<\/p>

你好 @karangdika您可以分享您为POD和服务网络配置的IP子网吗？

你好 @karangdika您可以分享您为POD和服务网络配置的IP子网吗？

嗨何塞，

我有192.168.2.x段为我们当前的访客VM，CVM和主机，PE和PC

我有192.168.3.x段为我的kbs群集，与棱镜启用了dhcp。

虽然网络吊舱我用默认的棱镜中心建议我

网提供商​​：法兰绒

豆荚：172.20.0.0/16

服务：172.19.0.0/16

我没有在我的路由器和交换机上设置这个网络。我需要先在路由器上安装这个网络吗?或者我把它换成现在的段2。x或者x 3. ?

对不起，如果我有一个愚蠢的错误。

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是否没有使用VM或K8S段作为POD或服务范围。

在这一点上，我建议你在支持的情况下开放一个案例，它会比试图在这里锻炼的速度更快，这使得您的部署失败。

问候,

何塞

啊，我看到了。所以从整个设置中，我的KBS应该正常部署？但是错误的错误阻止它。

好的，谢谢 @josentanix.然后我会开票。

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