虚拟化与容器化

虚拟机与容器对比

• • 虚拟机：资源隔离好，启动慢，资源占用高
• • 容器：轻量级，启动快，易于弹性伸缩

Docker基础命令

docker build -t myapp .
docker run -d -p 8080:80 myapp

Kubernetes部署示例

  replicas: 2
  selector:
    matchLabels:
      app: myapp
  template:
    metadata:
      labels:
        app: myapp
    spec:
      containers:
      - name: myapp
        image: myapp:latest
        ports:
        - containerPort: 80
