配置文件到集群类变量转换

本主题介绍了工作负载集群配置文件中的变量如何转换为基于类的 Cluster 对象及其 ClusterBootstrap 以及 Tanzu Kubernetes Grid (TKG) 中的其他辅助对象中的变量设置。有关 Cluster 对象及其辅助对象的示例，请参见下面的 Cluster 对象及其辅助对象的示例。

概览：配置文件和集群类变量

配置文件变量和基于类的集群变量不同：

  • 配置文件变量包括：

  • 基于类的集群变量设置是 Cluster 或 ClusterBootstrap 对象规范中的嵌套 YAML 设置：

    • Cluster 对象设置包括：

      • 大多数可用的集群设置，并且可以任意更改。
      • 由 ClusterClass 对象定义，设置为集群的 spec.topology.class 值。
      • 在 spec.topology 下的 controlPlane、workers 或 variables 块中设置。

      • 示例设置：

        variables:
- name: imageRepository
  value:
    host: stg-project.vmware.com
    • ClusterBootstrap 设置是容器网络和其他低级别基础架构的一些一次性设置，无法在现有集群中进行更改。

使用集群配置文件运行 tanzu cluster create 命令（如创建基于类的集群中所述）时，Tanzu CLI 执行此转换。

节点配置

下表列出了用于配置控制平面和工作节点以及节点实例运行的操作系统的变量。有关配置文件变量列中变量的信息，请参见《配置文件变量参考》中的节点配置。

在基于类的集群对象结构列中，所有 name / value 对设置都位于 spec.topology.variables 下的 Cluster 对象定义中。此列中的示例代码适用于 vSphere 上的 Cluster 个对象；AWS 和 Azure 上的对象结构可能不同。

    host: example.com/yourproject
    tlsCertificateValidation: 
      enabled: false
 tldCertificateValidation.enabled 会反转TKG_CUSTOM_IMAGE_REPOSITORY_SKIP_TLS_VERIFY 的布尔设置，如果其值为 true，则不会写入该设置。 
TKG_HTTP_PROXY_ENABLED: true
TKG_HTTP_PROXY: http://proxy.example.com:80

    - noproxy.example.com
    - 192.168.0.0/24
