什么是karbon？

Nutanix Karbon是一种精心策划的交钥匙产品，可提供简化的Kubernetes簇的配置和操作。Kubernetes是用于部署和管理基于容器的应用程序的开源容器编排系统。

Karbon Web控制台通过简单的GUI和内置事件监视工具简化了Kubernetes群集的部署和管理。

有内置的附加组件，例如Kibana和Prometheus，用于解析日志并监视群集中的警报触发机构。

使用Karbon您可以：

  • 部署Kubernetes群集。
  • 为您的应用程序使用Nutanix卷和Nutanix文件存储。
  • 管理Kubernetes群集资源。
  • 升级您的Kubernetes部署。
  • 确保高可用性。

要设置您的Karbon环境，请执行以下任务：

你好 @Jubran

我们对Karbon有问题。我们无法从UI下载图像。我们已经激活了浏览器开发人员选项，以查看对API的调用。

当我们单击“ Donwload Centos”按钮时，浏览器会显示此信息。第一个错误只是加载页面。第二个是单击按钮时。

阅读您的链接，我们检查了“ Docker PS”，以查看容器是否正在运行。只有UI开始。在重新启动“ Karbon-Core”和“ Karbon-UI”容器之后，核心容器再次结束。

PCVM：〜$ Docker PS
容器ID图像命令创建的状态端口名称
AD6A66B6B524 KARBON核：v2.1.0“/karbon-debug = tr ...” 1秒前不到一秒钟（健康：开始）karbon-core
2FA0A11CA907 KARBON-UI：v2.1.0“/start.sh”大约一分钟前大约一分钟（健康）Karbon-UI
PCVM：〜$ Docker PS
容器ID图像命令创建的状态端口名称
2FA0A11CA907 KARBON-UI：v2.1.0“/start.sh” 5分钟前UP 5分钟（健康）Karbon-UI

有什么想法可能是问题吗？

还有一个问题：Karbon是否需要启用冷静或应用程序管理？我们没有启用此服务（Calm＆Epsilon）。

问候。
哈维尔

Hello @Jubran<\/user-mention>\u00a0<\/p>

\u00a0<\/p>

We have a problem with Karbon. We can\u2019t download images from the UI. We have activated\u00a0browser developer options to see the calls to API.

When we click the button \u201cDonwload Centos\u201d the browser shows this. The first one error is just loading the page. The second is when button is clicked.
\u00a0<\/p>

\"//www.jhbzcj.com/next/karbon-kubernetes-orchestration-30/\"<\/figure>

\u00a0<\/p>

Reading your links we checked \u201cdocker ps\u201d to see if the containers are running. Only UI was started. After restarting \u201ckarbon-core\u201d and \u201ckarbon-ui\u201d containers, the core container ends failing again.
\u00a0<\/p>

PCVM:~$ docker ps
CONTAINER ID        IMAGE                COMMAND                  CREATED              STATUS                                     PORTS               NAMES

PCVM:~$ docker ps

<\/code><\/pre>
Any idea of what could be the problem?<\/p>
One more question: Does Karbon need to have Calm enabled or App management? We don\u2019t have enabled this services (calm & epsilon).<\/p>

你好，

是否可以选择通过API或CLI进行操作？我们想使用IAAC（实际上是gitops），无法使用GUI的步骤……

谢谢

Hi,<\/p>

Is there option to do it through API or CLI? We want to use IaaC (actually GitOps) and the steps through GUI cannot be used\u2026<\/p>

你好 @Jmoro，，，，

Karbon群集不需要冷静或启用应用程序管理。

您能打开支持案吗？Karbon核日志中可能有一些支持可以用来弄清为什么没有启动容器的东西。

Hello @jmoro<\/user-mention>,<\/p>

Karbon Cluster doesn\u2019t require Calm or App management enabled.<\/p>

Could you open a support case? There\u2019s probably something in the karbon-core logs that support can use to figure out why the container wasn\u2019t started.<\/p>","quoteUsername":"vshuguet","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

你好 @Assaf Katz，，，，

您能解释一下您想做什么吗？

Karbon群集确实有API，您可以在此处找到它们：https://www.nutanix.dev/reference/karbon/

我们还有一个名为KarbonCtl的CLI，您可以在文件夹中的Prism Central VM上找到：

你好 @vshuguet，，，，

我想在此线程中获得类似于第一篇文章的结果，但自动，没有任何用户干预（文件中有一些可能的配置详细信息除外）。我找到了API文档并提到了，但是如果没有深入了解过程中的每个步骤（比那里的内容要深得多），几乎不可能编写此类文档。

理想情况下，类似：

karbonctl创建群集-f configuration.json

最好，但我找不到这样的选择。

谢谢

Hi @vshuguet<\/user-mention>,<\/p>

I want to get same outcome like first post in this thread but automatically, without any user intervention (except a few as possible configuration details in file). I found the APIs documentation and mentioned, but it is almost impossible to write such document without deep knowledge of what exactly each step in process do (much deeper level than what it is written there).<\/p>

Ideally, something like:<\/p>

karbonctl create-cluster -f configuration.json<\/code><\/pre>
Would be best, but I couldn\u2019t find such option.<\/p>

哦好的。

使用CLI创建集群超出了一般Karbon文档的范围。

但是，我们在这本KB文章中记录了该过程：https://portal.nutanix.com/kb/9601

此致，

产品经理-Karbon Clusters＆Kubernetes @ nutanix
Oh, okay.<\/p>

Creating a cluster using the CLI is beyond the scope of the general Karbon documentation.<\/p>

However, we have the process documented in this KB article:\u00a0https:\/\/portal.nutanix.com\/kb\/9601<\/a><\/p>

谢谢您的建议。最后一个PC更新（2020.8）解决了问题。我忘了对此帖子发表评论。

感谢大家的帮助。

Thanks, for your suggestion. The last PC update (2020.8), solved the problem. I forgot to comment on the post about it.<\/p>
