牛刀小试

文件名nginx-deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
spec:
  selector:
    matchLabels:
      app: nginx
  replicas: 2
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
        - name: nginx
          image: nginx:1.8
          ports:
            - containerPort: 80
          volumeMounts:
            - mountPath: "/usr/share/nginx/html"
              name: nginx-vol
      volumes:
        - name: nginx-vol
          emptyDir: {}

我们会部署两个nginx,volumeMounts，name是下面这个volumes,不想使用docker的默认_data来数据存储

这个里面，我们使用

### 创建
kubectl apply -f nginx-deployment.yaml
### 部署好，查看状态
kubectl get pods -l app=nginx
### 描述pod，可以看下面的event
kubectl describe pod nginx-deployment-748c6fff66-49wbv


### 更新，此处的更新就是yaml配置文件更新
kubectl apply -f nginx-deployment.yaml
### 删除
kubectl delete -f nginx-deployment.yaml
