Answer 1

In the docker container on which the Airflow server is running, the process is already running on port 8793, which defaults to the worker_log_server_port parameters in airflow.cfg. I changed the port to 8795 and the team worked airflow worker.

8793 : lsof i:8793, , : kill $(lsof -t -i:8793). ubuntu , lsof:

apt-get update
apt-get install lsof
