在断开连接模式下运行的 Anthos 示例配置文件参考文档

以下示例配置文件可用于在断开连接模式下运行的 Anthos，帮助您了解用于管理集群或配置 Anthos 功能的产品 API。

管理员集群和 NodePool

以下是在断开连接模式下运行的 Anthos 管理员集群配置文件示例。

关于示例的说明：

• 文件开头的 actl 配置变量是有效的 YAML，但不是有效的 Kubernetes 资源；只有在使用 actl 创建初始管理员集群时，才能包含该变量。
• 必须将集群名称命名为 admin。
• spec.type 字段必须是 admin。
• 配置参数不支持 shell 扩展。必须指定绝对路径。

# actl configuration variables. Because this section is valid YAML but not a
# valid Kubernetes resource, this section can only be included when using actl
# to create the initial admin cluster. Afterwards, when creating user clusters
# by directly applying the cluster and node pool resources to the existing admin
# cluster, you must remove this section.
#
sshPrivateKeyPath: <path to SSH private key, used for node access>
registryMirrors:
# Registry endpoint to pull images from. If the registry has a namespace append
# 'v2' after the registry ip or hostname.
# Example: https://registry.example.com/v2/library
- endpoint: <private registry>
  # Example: /home/USER/.docker/config.json
  pullCredentialConfigPath: <private registry config file>
  # Not needed for trusted domain.
  # Example: /etc/docker/certs.d/registry.example.com/ca.crt
  caCertPath: <private registry TLS cert>
