尝试设置Airflow时出现Docker错误“无法启动Docker Compose应用程序”

Question

我在试图在Airflow上显示我的本地DAG时遇到了一些问题。

我用Docker部署了Airflow，但是我没有显示我本地计算机上的Dag，它只显示了我在“docker-compose.yaml”文件中设置airflow时出现的“标准”Dag。

我的 dag/日志文件的路径是：C：\用户\taz\文档\工作区（工作区是我拥有 dag 和日志文件夹的文件夹）

这是“docker-compose.yaml”

version: '3'
x-airflow-common:
  &airflow-common
  # In order to add custom dependencies or upgrade provider packages you can use your extended image.
  # Comment the image line, place your Dockerfile in the directory where you placed the docker-compose.yaml
  # and uncomment the "build" line below, Then run `docker-compose build` to build the images.
  image: ${AIRFLOW_IMAGE_NAME:-apache/airflow:2.2.5}

在尝试运行docker时，我收到了错误消息。

您尚未设置$AIRFLOW_HOME的环境变量，这就是为什么它显示您的匕首，因为此变量是气流的主页/目录，并且您的音量/ mnt是指向匕首的路径
