Cloud DNS 范围是一种将专用 DNS 资源附加到 Google Cloud 对象的灵活方式。最初,您只能将专用 DNS 资源(例如专用 DNS 地区、政策和对等互连地区)连接到 Virtual Private Cloud (VPC) 网络。使用 DNS 范围,您不仅可以将资源挂接到多个 Google Cloud 网络,还可以将资源连接到更小的分组(例如 Google Kubernetes Engine [GKE] 集群)。您可以将专用 DNS 资源附加到范围,而不是将网络 DNS 资源附加到网络。
借助 Cloud DNS 范围,您可以将专用 DNS 资源附加到 VPC 网络和 GKE 集群。您可以在特定范围的边界内(例如在网络中)创建自定义 DNS 视图。例如,一个网络中的多个 GKE 集群可以有自己的 cluster.local DNS 层次结构。
根据您希望向整个 VPC 网络显示 DNS 名称还是对 GKE 集群使用 DNS 名称,您可以创建 VPC 范围或 GKE 集群级 DNS 地区:
VPC 范围。如果 DNS 名称必须在网络范围内解析,请使用此范围。VPC 范围的 DNS 区域允许 DNS 名称可用于整个 VPC 网络。
GKE 集群范围。Cloud DNS 允许您为单个 GKE 集群创建范围。然后,您可以为每个集群创建一个或多个专用托管地区,就像为网络创建托管地区一样。来自该集群的查询首先检查该查询是否可由范围限定于该特定 GKE 集群的资源应答。否则,查询会回退到正常匹配,首先检查网络级资源是否可以解答查询。
范围层次结构
DNS 解析发生在最具体的可用范围内,而在较低范围内找不到地区时,将遍历层次结构。集群是最具体的范围,Cloud DNS 会先检查有无匹配项。
