有时，当我们尝试从Prism Central上开放Karbon Management GUI时，Kubernetes群集不会列出。这是由于Karbon（Karbon_Core＆Karbon_UI）容器处于不健康状态。这可能是由于各种原因，其中一个是Docker容器无法获得适当的资源，或者Docker无法与Karbon容器建立连接。以下是人们会注意到何时进入Karbon控制台的屏幕截图，并且没有列出Kubernetes群集。

症状是容器不健康，这是尝试作为第一步的简单解决方案：

karbon容器karbon_core是不良。

Karbon容器Karbon_Core不健康。
nutanix@ntnx-10-x-x-x-x-a-pcvm：〜$ docker PS
容器ID图像命令创建的状态端口名称
3CF0CB9A9DEE KARBON核：v1.0.1“/start.sh” 5个月前5个月（不健康）karbon-core
912C005D1585 KARBON-UI：V1.0.1“/start.sh” 7个月前，UP 7个月Karbon-UI
nutanix@ntnx-10-10-10-100-225-a-pcvm：〜$

以下是执行行动计划时需要记住的一些事情：

冷静的- 确保在此阶段没有镇定的活动。
karbon- 在Karbon的Docker重新启动期间，您将无法对API服务器进行身份验证。因此，在Karbon_Core服务出现之前，Kubectl将失败。
nutanix对象- 确保不进行升级或对象存储部署。
Nutanix流-不可能创建，更新或删除安全策略和类别。不可能分配或删除VM到类别。

解决方案：

1.停止Karbon Services，Karbon_Core和Karbon_UI：

nutanix@pcvm：〜创世记停止karbon_core
nutanix@pcvm：〜创世记停止karbon_ui

2.重新启动Docker守护程序：

nutanix@pcvm $ sudo systemctl停止Docker-latest
nutanix@pcvm $ sudo systemctl start docker-latest

3.重新启动Docker守护程序后，启动Karbon Services，Karbon_Core和Karbon_UI：

nutanix@pcvm $群集开始

检查karbon容器的状态。他们现在应该处于健康状态：

nutanix@pcvm $ docker PS

容器ID图像命令创建的状态端口名称
319FAD4E6A0E KARBON核：v1.0.1“/start.sh”大约一分钟前大约一分钟（健康）karbon核
8265a6289f0c karbon-ui：v1.0.1“/start.sh”大约一分钟前大约一分钟karbon-ui

Sometimes Kubernetes clusters are not listed when we try to open Karbon console from Karbon management GUI on Prism Central. This is due to Karbon (karbon_core & karbon_ui) containers being in an unhealthy state. This can be due to various reasons, one of them being\u00a0docker containers are unable to get the proper resources or docker is unable to establish a connection with Karbon containers. Below is a screenshot of what one would notice when one would go to the Karbon console and no Kubernetes clusters are listed.<\/p>

\u00a0<\/p>

Symptoms are container is unhealthy and here is the simple fix to try as a first step:<\/p>

\u00a0<\/p>

\u00a0The Karbon container karbon_core is\u00a0unhealthy<\/strong>.<\/p>

 The Karbon container karbon_core is unhealthy.
nutanix@NTNX-10-X-X-X-A-PCVM:~$ docker ps

Below are some of the things you need to keep in mind while executing the action plan:<\/p>
Calm<\/strong><\/em>\u00a0- Ensure no activity\u00a0is happening in Calm at this stage.<\/li>\t
Karbon<\/strong><\/em>\u00a0- During the docker restart of Karbon, you would not be able to authenticate to the API server. Hence\u00a0kubectl\u00a0will fail till the\u00a0karbon_core\u00a0service\u00a0comes up.<\/li>\t
Nutanix Objects<\/strong><\/em>\u00a0- Ensure no upgrades or object store deployments are in progress.<\/li>\t
Nutanix Flow<\/em>\u00a0-\u00a0<\/strong>It will not be possible to create, update, or delete security policies and categories. It will not be possible to assign or remove VM to\/from Categories.<\/li><\/ol>\u00a0<\/p>
Solution:<\/strong><\/p>
\u00a0<\/p>
1. Stop Karbon services,\u00a0karbon_core\u00a0and\u00a0karbon_ui:<\/p>
nutanix@PCVM:~ genesis stop karbon_core
nutanix@PCVM:~ genesis stop karbon_ui<\/code><\/pre>2. Restart the docker daemon:<\/p>
nutanix@PCVM$ sudo systemctl stop docker-latest
nutanix@PCVM$ sudo systemctl start docker-latest<\/code><\/pre>\u00a0<\/p>
3. Once docker daemon is restarted, start the Karbon services,\u00a0karbon_core\u00a0and\u00a0karbon_ui:<\/p>
nutanix@PCVM$ cluster start\u00a0<\/pre>\u00a0<\/p>
Check the status of Karbon containers. They should be in a healthy state now:\u00a0<\/li><\/ol>nutanix@PCVM$ docker ps
