我正在使用气流稳定的舵图并使用Kubernetes Executor,新的Pod计划用于dag,但找不到dag_id失败的问题.我正在使用git-sync来获取数据.以下是错误和kubernetes的配置值.有人可以帮我解决这个问题吗?
错误:

我遇到了同样的问题.我通过将以下内容添加到我的配置中来解决了这个问题:
AIRFLOW__KUBERNETES__DAGS_VOLUME_SUBPATH: repo/发生的事情是,初始化容器将在[AIRFLOW__KUBERNETES__GIT_DAGS_FOLDER_MOUNT_POINT]/[AIRFLOW__KUBERNETES__GIT_SYNC_DEST]中下载您的数据,而AIRFLOW__KUBERNETES__GIT_SYNC_DEST默认为repo( airflow.apache/docs/stable/configurations-ref.html#git-sync-dest )
I am using airflow stable helm chart and using Kubernetes Executor, new pod is being scheduled for dag but its failing with dag_id could not be found issue. I am using git-sync to get dags. Below is the error and kubernetes config values. Can someone please help me resolve this issue?

I had the same issue. I solved it by adding the following to my config:
AIRFLOW__KUBERNETES__DAGS_VOLUME_SUBPATH: repo/What was happening is that the init container will download your dags in [AIRFLOW__KUBERNETES__GIT_DAGS_FOLDER_MOUNT_POINT]/[AIRFLOW__KUBERNETES__GIT_SYNC_DEST] and AIRFLOW__KUBERNETES__GIT_SYNC_DEST by default is repo (airflow.apache/docs/stable/configurations-ref.html#git-sync-dest)
