k8s入门-3 测试部署nginx

不同版本k8s的yaml写法不太一样，我的是1.22.0版本

1、创建Nginx-svc.yaml文件

apiVersion: v1
kind: Service
Metadata:
  namespace: default
  name: Nginx-svc
  labels: 
    name: Nginx-svc
spec:
  type: NodePort
  ports:
  - port: 80
    protocol: TCP
    targetPort: 80
    name: http
    nodePort: 30001
  selector:
    name: Nginx-pod

2、创建Nginx的service服务

kubectl create -f Nginx-svc.yaml

3、查看Nginx的service实例

kubectl get svc -n default -owide　

或

kubectl get service

 

 

4、创建Nginx 副本控制器

4.1创建Nginx-rc.yaml文件

apiVersion: v1
kind: ReplicationController
Metadata:
  namespace: default
  name: Nginx-rc
  labels:
    name: Nginx-rc
spec:
  replicas: 1
  selector:
    name: Nginx-pod
  template:
    Metadata:
      labels: 
        name: Nginx-pod
    spec:
      containers:
      - name: Nginx
        image: Nginx
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 80

4.2创建Nginx的ReplicationController

kubectl create -f Nginx-rc.yaml

4.3查看Nginx的pod

kubectl get pod -n default -owide

kubectl get pods

 

 5、通过这里可以看到部署到节点1上了

 

 直接在浏览器里输入节点1的ip+30001,输出
