一、使用如下yaml即可

apiVersion: apps/v1
kind: Deployment
metadata:
  annotations:
    deployment.kubernetes.io/revision: "1"
  generation: 1
  labels:
    k8s-app: nginx
    qcloud-app: nginx
  managedFields:
  - apiVersion: apps/v1
    manager: tke-apiserver
    operation: Update
  - apiVersion: apps/v1
    manager: kube-controller-manager
    operation: Update
  name: nginx3
  namespace: default
spec:
  progressDeadlineSeconds: 600
  replicas: 1
  revisionHistoryLimit: 10
  selector:
    matchLabels:
      k8s-app: nginx
  strategy:
    rollingUpdate:
      maxSurge: 1
      maxUnavailable: 0
    type: RollingUpdate
  template:
    metadata:
      labels:
        k8s-app: nginx
        qcloud-app: nginx
    spec:
      affinity:
        nodeAffinity:
          preferredDuringSchedulingIgnoredDuringExecution:          #尽量满足条件（调度期间如果满足其中一个亲和性条件则调度到对应node，如果没有节点满足条件则随机调度到任意节点）
          - preference:
              matchExpressions:
              - key: kubernetes
                operator: In
                values:
                - ljx1
            weight: 1
          requiredDuringSchedulingIgnoredDuringExecution:         #强制满足条件（调度期间如果满足其中一个亲和性条件则调度到对应node，如果没有节点满足条件则调度失败）
            nodeSelectorTerms:
            - matchExpressions:
              - key: kubernetes
                operator: In
                values:
                - ljx
      containers:
      - image: nginx:latest
        imagePullPolicy: Always
        lifecycle:
            postStart:
              exec:
                command:
                  - /bin/sh
                  - '-c'
                  - su -s /bin/sh -c " chmod -R 777 /data/log/nginxlog"
        name: nginx
        resources:
          limits:
            cpu: 500m
            memory: 256Mi
          requests:
            cpu: 250m
            memory: 128Mi
        securityContext:
          privileged: false
      dnsPolicy: ClusterFirst
      imagePullSecrets:
      - name: secret
      restartPolicy: Always
      schedulerName: default-scheduler
      securityContext: {}
      terminationGracePeriodSeconds: 30

二、node节点添加label方法

添加label语法
kubectl label nodes <node-name> <label-key>=<label-value> 

添加lebel示例
kubectl label node node1 kubernetes=ljx

查看node节点label
kubectl get node --show-labels

三、node节点删除label方法

删除label语法
kubectl label nodes <node-name> <label-key>-

删除label示例
kubectl label node node1 kubernetes-
