docker compose -h # 查看帮助
docker compose up # 启动所有 docker compose 服务
docker compose up -d # 启动所有 docker compose 服务并后台运行
docker compose down # 停止并删除容器、网络、卷、镜像。
docker compose exec yml里面的服务id # 进入容器实例内部 docker compose exec docker-compose.yml文件中写的服务id /bin/bash
docker compose ps # 展示当前 docker compose 编排过的运行的所有容器
docker compose top # 展示当前 docker compose 编排过的容器进程
docker compose logs yml里面的服务id # 查看容器输出日志
docker compose config # 检查配置
docker compose config -q # 检查配置，有问题才有输出
docker compose restart # 重启服务
docker compose start # 启动服务
docker compose stop # 停止服务

# 默认 container_name = docker-compose.yml文件所在的目录名-serviceId-1，例如：fdrcloud-yun_redis-1
