https://airflow.apache.org/docs/apache-airflow/stable/start/docker.html

我正在遵循上述安装指南。在它说的步骤：

echo -e "AIRFLOW_UID=$(id -u)\nAIRFLOW_GID=0" > .env

我认为它应该创建一个 .env 文件，但它并没有为我创建任何东西。如果我使用 ls 命令 .env 不会出现。

如果我尝试继续下一步：

docker-compose up airflow-init

我收到以下错误：

我在 AWS EC2 实例上使用 Ubuntu 20.04。

【问题讨论】：

echo -e "AIRFLOW_UID=$(id -u)\nAIRFLOW_GID=0" > .env 在 bash 中对我来说很好用。
您尝试添加此echo -e "AIRFLOW_UID=50000\nAIRFLOW_GID=50000" >> .env 吗？对此进行了讨论 - github.com/apache/airflow/discussions/13855

标签： linux docker shell docker-compose airflow

【解决方案1】：

关于.env 文件，仅使用ls 命令可能看不到它，但可能存在。尝试执行ls -a 以显示隐藏文件。以 . 开头的文件默认隐藏。

我认为您的第二个问题是docker-compose 的权限问题。尝试运行 sudo docker-compose up airflow-init 或 add your user to the docker group。
