Answer 1

For anyone who use the docker-airflow, I used the folk of puckel/docker-airflow Just need to modify the dockerfile by adding

   && pip install 'redis>=2.10.5,<3'\

replace celery[redis] with only celery, by adding celery in apache-airflow built-in module i.e.,

  && pip install apache-airflow[crypto,celery,postgres,hive,jdbc,mysql]==$AIRFLOW_VERSION 

Update: They also change the docker-airflow dockerfile recently to fix this bug, see here
