$ docker-compose -v

# -f 指定compose配置文件
# 如果没有指定-f选项,则默认会查找当前目录下的docker-compose.yml和docker-compose.override.yml,后者配置会追加或覆盖前者
$ docker-compose up
# 可以指定多个配置文件,如果配置字段相同,则后者会覆盖前者,如果不同则会合并配置文件,compose按照文件顺序构建配置
$ docker-compose -f docker-compose.yml -f docker-compose.admin.yml run backup_db
# 如下两个配置文件内容,volumes字段相同则后者会覆盖前者,最终结果为/data, admin.yml中的其他字段将会合并到前者
