Karbon是什么?

Nutanix Karbon是一个精心策划的交钥匙产品，提供了Kubernetes集群的简化配置和操作。Kubernetes是一个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。

通过一个简单的GUI和内置的事件监控工具，Karbon web控制台简化了Kubernetes集群的部署和管理。

在集群中有内置的插件，如Kibana和Prometheus，用于解析日志和监控警报触发机制。

使用碳，你可以:

部署Kubernetes集群。
使用Nutanix卷和Nutanix文件存储您的应用程序。
管理Kubernetes集群资源。
升级Kubernetes部署。
确保高可用性。

为了设置您的carbon环境，请执行以下任务:

通过Prism Central启用carbon，使Karbon
下载镜像，请参见操作系统映像

你好 @Jubran

我们对卡本有意见。我们不能从UI下载图像。我们已经激活了浏览器开发者选项来查看对API的调用。

当我们点击“下载Centos”按钮时，浏览器会显示这个。第一个错误是加载页面。第二个是当按钮被点击时。

阅读你的链接，我们检查了“docker ps”，看看容器是否正在运行。只有UI被启动。重新启动“carbon -core”和“carbon -ui”容器后，核心容器再次失败。

PCVM: ~ $码头工人ps 容器id image命令创建的状态端口名称 Ad6a66b6b524 carbon -core:v2.1.0 "/ carbon -debug=tr…不到一秒钟(健康:启动)碳核 2fa0a11ca907 karbon-ui:v2.1.0 "/start.sh"大约一分钟前大约一分钟(健康)karbon-ui PCVM: ~ $码头工人ps 容器id image命令创建的状态端口名称上5分钟(健康)karbon-ui

知道是什么问题吗?

还有一个问题:carbon是否需要启用Calm或应用程序管理?我们没有启用这个服务(calm & epsilon)。

的问候。
哈维尔

Hello @Jubran<\/user-mention>\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>
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.
