docker - 设置 Apache Airflow 时无法执行脚本 docker-compose

Question

我正在使用 Docker Compose 来设置 Apache Airflow，并且在我使用时

docker-compose up airflow-init

我收到此错误:

这是我正在使用的 yaml 文件:https://airflow.apache.org/docs/apache-airflow/stable/docker-compose.yaml

Answer 1

也许您已经安装了 docker，但它没有运行，或者您的用户未配置为访问它。

这与此处描述的错误相同:

https://github.com/docker/compose/issues/7896

您可以通过运行docker ps来仔细检查它。如果它没有显示任何进程(但没有出错)，那么您的 docker 正在运行并且配置正确。

另一件事是要检查您的用户是否已正确配置为访问 docker。在 Linux 上，您应该确保您的用户已添加到 docker 组。请参阅https://docs.docker.com/engine/install/linux-postinstall/
