Docker Swarm集群設置
在主要伺服器上初始化Swarm

docker swarm init

添加其他節點到Swarm集群

docker swarm join --token <token> <manager-ip>:<port>

創建一個 docker-compose.yml 文件，定義服務、網絡和卷

version: '3.8'

services:
  web:
    image: your-dockerhub-username/your-image-name:latest
    ports:
      - "80:80"
    deploy:
      replicas: 3
      update_config:
        parallelism: 2
        delay: 10s
      restart_policy:
        condition: on-failure

這一系列步驟確保了應用從代碼提交到自動部署的全過程都能自動化，並且應用能夠在Docker Swarm中穩定運行
