By default, when generating a task instance,
DockerOperator
will create a new temporary directory and mount it to the Docker temporary directory. But in the Airflow version2.1
,DockerOperator
usesmounts
instead ofvolumes
attributes to mount that temporary directory. With themounts
attribute, the Docker engine does not automatically create a new directory if its path does not exist in the Docker host, but generates an error.Here is the doc: https://docs.docker.com/storage/bind-mounts/#differences-between--v-and---mount-behavior
