Pods
A Records
When enabled, pods are assigned a DNS A record in the form of “pod-ip-address.my-namespace.pod.cluster.local”.
For example, a pod with IP 1.2.3.4 in the namespace default with a DNS name of cluster.local would have an entry: 1-2-3-4.default.pod.cluster.local.
正在寻找kubernetes的记录中的名字格式荚DNS A记录与IP的理由的说明。如果客户端知道IP,以构建记录名称,一个DNS查询,为什么一个DNS查询?
