什么是卡尔邦？

Nutanix Karbon是一种策划交钥匙，提供了Kubernetes集群的简化配置和操作。Kubernetes.是一个开源容器编排系统，用于部署和管理基于容器的应用程序。

Karbon Web控制台简化了具有简单GUI和内置事件监控工具的Kubernetes集群的部署和管理。

有内置的加载项如Kibana和Prometheus，用于解析日志和监视群集中的警报触发机制。

使用karbon你可以：

  • 部署Kubernetes集群。
  • 为您的应用程序使用Nutanix卷和Nutanix文件存储。
  • 管理Kubernetes群集资源。

你好 @jubran.

我们有卡尔邦的问题。我们无法从UI下载图像。我们有激活的浏览器开发人员选项可查看对API的调用。

当我们单击“Donwload CentOS”按钮时，浏览器会显示此功能。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开始了。重新启动“Karbon-Core”和“Karbon-UI”容器后，核心容器结束再次发生故障。

PCVM：〜$ Docker PS
容器ID图像命令创建状态端口名称
Ad6a66b6b524卡骨核心：v2.1.0“/ karbon -debug = tr ...”1秒前少于一秒钟（健康：启动）卡片核心
2fa0a11ca907 karbon-ui：v2.1.0“/start.sh”大约一分钟左右（健康）karbon-ui
PCVM：〜$ Docker PS
容器ID图像命令创建状态端口名称
2fa0a11ca907 karbon-ui：v2.1.0“/start.sh”5分钟前5分钟（健康）karbon-ui

任何可能是问题的想法吗？

还有一个问题：卡氏是否需要进行平静或应用程序管理？我们没有启用此服务（平静和epsilon）。

问候。

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
ad6a66b6b524        karbon-core:v2.1.0   \"\/karbon -debug=tr...\"   1 second ago         Up Less than a second (health: starting)                       karbon-core
2fa0a11ca907        karbon-ui:v2.1.0     \"\/start.sh\"              About a minute ago   Up About a minute (healthy)                                    karbon-ui
PCVM:~$ docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                   PORTS               NAMES
2fa0a11ca907        karbon-ui:v2.1.0    \"\/start.sh\"         5 minutes ago       Up 5 minutes (healthy)                       karbon-ui
<\/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，

是否有选择通过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.那

Karbon集群不需要启用平静或应用程序管理。

你能打开一个支持案例吗？在卡骨核心日志中可能会有一些东西，支持可以用来弄清楚为什么没有启动容器。

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.那

你能解释一下你想做什么吗？

Karbon集群确实有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，您可以在文件夹中找到棱镜中央VM：

你好 @vshuguet.那

我想在这个线程中的第一个帖子等同样的结果，但自动，没有任何用户干预（除了文件中可能的配置细节之外）。我找到了API文档并提到了，但几乎不可能编写此类文件，而无需深入了解进程中的每个步骤（比写在那里的更深层次）。

理想情况下，如：

KarbonCtl Create-Cluster -F Configuration.json

最好的，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创建群集超出了通用Karbon文档的范围。

但是，我们在此kB文章中有以下过程：https://portal.nutanix.com/kb/9601.

最好的祝福，

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>

你好 @vshuguet.

谢谢，为了你的建议。最后一个PC更新（2020.8），解决了问题。我忘了评论关于它的帖子。

感谢大家的帮助。
