仅限腾讯云TKE集群中使用，其他容器集群或者自建仅参考，依赖于环境

1，节点相关

表格输出各节点占用的 podCIDR

kubectl get no -o=custom-columns=INTERNAL-IP:.metadata.name,EXTERNAL-IP:.status.addresses[1].address,CIDR:.spec.podCIDR
INTERNAL-IP             EXTERNAL-IP     CIDR
172.30.2.5              139.186.202.9   172.16.0.0/26

表格输出各节点总可用资源 (Allocatable)
kubectl get no -o=custom-columns="NODE:.metadata.name,ALLOCATABLE CPU:.status.allocatable.cpu,ALLOCATABLE MEMORY:.status.allocatable.memory"
NODE                    ALLOCATABLE CPU   ALLOCATABLE MEMORY
172.30.2.5              1930m             1347064Ki

输出各节点已分配资源的情况
kubectl get nodes --no-headers | awk '{print $1}' | xargs -I {} sh -c "echo {} ; kubectl describe node {} | grep Allocated -A 5 | grep -ve Event -ve Allocated -ve percent -ve --;"

##
kubectl  get node  -ocustom-columns=节点名称:.metadata.name,节点IP:节点IP.status.addresses[0].address,实例ID:.metadata.labels."cloud\.tencent\.com\/node-instance-id",providerID:.spec.providerID
##查看节点的内核版本
kubectl  get node  -ocustom-columns=节点名称:.metadata.name,节点内核:.status.nodeInfo.kernelVersion,节点UUID:.status.nodeInfo.machineID,实例ID:.metadata.labels."cloud\.tencent\.com\/node-instance-id"
