[2. namespace 添加注解 scheduler.alpha.kubernetes.io/node-selector](#2. namespace 添加注解 scheduler.alpha.kubernetes.io/node-selector)
[3. label node](#3. label node)

1. apiserver 启用准入控制 PodNodeSelector

vim /etc/kubernetes/manifests/kube-apiserver.yaml

yaml 复制代码

spec:
  containers:
  - command:
    - kube-apiserver
    - --advertise-address=192.88.1.172
    - --enable-admission-plugins=NodeRestriction,PodNodeSelector

2. namespace 添加注解 scheduler.alpha.kubernetes.io/node-selector

bash 复制代码

kubectl get ns xx -o yaml > xx.yaml
vim xx.yaml

加入注解

yaml 复制代码

annotations:
    scheduler.alpha.kubernetes.io/node-selector: tenant-xx=true

yaml 复制代码

kubectl apply -f xx.yaml

最后xx namespace yaml如下：

yaml 复制代码

apiVersion: v1
kind: Namespace
metadata:
  annotations:
    scheduler.alpha.kubernetes.io/node-selector: tenant-xx=true
  name: xx
spec:
  finalizers:
  - kubernetes

3. label node

bash 复制代码

kubectl label nodes node01 tenant-xx=true
