K8S对node添加label,并根据label筛选节点

kubectl get node 10.88.10.5 –show-labels

kubectl label nodes kube-node node=kube-node

kubectl get node -a -l “node=kube-node”
pod或者rc的配置项中添加如下配置:

nodeSelector:
node: kube-node4
如mongo启动的rc文件

apiVersion: v1
kind: ReplicationController

volumes: [{“name”:”mongo”,”hostPath”:{“path”:”/root/volumes/mongo”}}]
