Find gunicorn log file in docker container

Question

I have a docker container running a python service with gunicorn. This is how the service was started :

gunicorn --bind 0.0.0.0:6435 --certfile=cert.pem --keyfile=key.pem --ssl-version=5 --ciphers=EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH app:app -w=5 --timeout=500 --daemon

But, i am unable to find log files for the 5 workers. What would be the default path to find these log files?

I tried using the find command find / -type f -name "hs_err_pid" since these are the default file names gunicorn saves the log files with. But this gives me the following permission errors:

    find: ‘/proc/1/map_files’: Operation not permitted
find: ‘/proc/16/map_files’: Operation not permitted
find: ‘/proc/89/map_files’: Operation not permitted

Any way to find out the log files?

Answer 1

I suggest you to add --access-logfile YOUR_FILE to your command to specify a file or redirect it to stdout using -. the same goes for error logs.
