官方文档：Running Airflow in Docker

airflow-init 容器用于进行初始化，会进行资源检测，要求： 内存：至少4G CPU核心：至少2个 磁盘空间：至少10G

为了安装时的权限，需要在.env 中设置AIRFLOW_UID，在linux下：

AIRFLOW_UID=0   # root用户

或者使用 ：echo -e "AIRFLOW_UID=$(id -u)" > .env tips：这里在测试的时候没有设置这个环境变量，容器一直处于健康检查状态

结合官方的docker compose ，经过测试可以安装和启动成功，只要进行Websoft9的docker-library改造即可
