I have containerized Airflow webserver, scheduler, flower and worker. I'm using MySQL for the backend and Redis for queuing. Everytime I spin up the worker node it throws the error below and all the Dags are stuck in running status.
Logs from the Worker Node:
File "/usr/lib64/python2.7/site-packages/MySQLdb/connections.py", line 193, in _init_
super(Connection, self)._init_(*args, **kwargs2)
OperationalError: (_mysql_exceptions.OperationalError) (2002, "Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)")
