pod容器固定到指定节点

先查看节点名称

[root@node1 ~]# kubectl get node
NAME        STATUS    ROLES     AGE       VERSION
k8s-work4   Ready     work4     2y        v1.11.1
k8s-work6   Ready     work6     2y        v1.11.1
node1       Ready     master    3y        v1.11.1
node2       Ready     master    3y        v1.11.1
node3       Ready     master    3y        v1.11.1

node4       Ready     node4     91d       v1.11.1
node5       Ready     node5     324d      v1.11.1
node7       Ready     node7     84d       v1.11.1
node8       Ready     node8     215d      v1.11.1

修改yaml文件

下面是通过label-selector机制选择节点

kubectl label node k8s-node1 type=node1
kubectl get nodes --show-labels
