[英]Find the cluster CIDR for service IP allocations in kuberneted
How can I find what IP block is used by the api-service (or whatever other component is responsible) to dole out the service IPs, from a live cluster. 我如何找到api服务(或负责任何其他组件)使用哪个IP块从活动群集中分发服务IP。
We use a self managed Kubernetes cluster deployed on AWS using terraform. 我们使用通过Terraform在AWS上部署的自我管理Kubernetes集群。 The networking is managed by Calico.
网络由Calico管理。 However from what I have read it seems like calico is only responsible for the pod and container IPs.
但是,从我阅读的内容来看,似乎calico仅负责容器和容器的IP。
您可以在命令下方运行,然后在输出中找到群集IP范围,例如--service-cluster-ip-range=xxxx/x
kubectl cluster-info dump | grep --color service-cluster-ip-range
这是在初始运行时传递给您的kube-apiserver的变量,例如:
--service-cluster-ip-range=10.3.0.0/20
