k8s 调度指定节点

1.根据节点名字调度

spec:
  nodeName: k8s-node1
  containers:
  - name: nginx
    image: nginx

2.根据标签调度

#打标签
kubectl label nodes  kub101 app1=mysql

#确认标签是都生效
kubectl get nodes --show-labels


#
spec:
     nodeSelector:
       deploy.type: assembly_app
     restartPolicy: Always
     containers:
     - name: nginx
       image: "nginx"

spec:
  nodeSelector:
    app1: mysql
  containers:
  - name: nginx
    image: nginx
