通用Docker部署脚本

为了方便使用Docker compose进行批发性的部署，下面提供了一个通用的使用DockerCompose的Docker项目部署脚本

其中

PROJECT NAME 为项目显示名称
COMPOSE_URL 为存放Docker compose文件的URL
PLACEHOLDER_PORT 为占位符，不需要修改
DEFAULT_PORT 为默认的对外端口

run-compose.sh脚本

COMPOSE_URL="https://.../.../*.yaml"
PLACEHOLDER_PORT="PORT"

compose示例

bash
services:
  redis:
    image: redis:7
    container_name: redis-db
    volumes:
      - redis_data:/data
    healthcheck:
      test: ["CMD", "redis-cli", "ping"]
      interval: 5s
      timeout: 3s
      retries: 5

  fastapi:
    image: xly23333/fastapi-redis 
    container_name: fastapi-app
    ports:
      - "PORT:6001"
    environment:
      REDIS_HOST: redis
      REDIS_PORT: 6379
    depends_on:
      redis:
        condition: service_healthy
volumes:
  redis_data:

这里的核心是：对外port的位置一定要书写为"PORT:容器内端口"，这样脚本就可以自动替换默认/用户输入的脚本

使用脚本

将脚本和compose全部放置在服务器上，开启一个web服务器，随后再任意设备上运行下面的命令来使用

bash
wget -N https://<URL>/<shellName>.sh && sudo sh ./<shellName>.sh

其中<URL>和<shellName>请根据自己的需要进行修改

目录

run-compose.sh脚本
