Can't login after using docker-compose up with admin_password specified in docker-compose.yaml

[MaxwellPSanders]

I am very new to Docker, so I am sure I am just missing something.
I followed the instructions of the docker installation, but after I did docker-compose up I realized I needed to make a port change, so I booted it back down, and forgot to take note of what the admin password was from the migrations.
I do not know what the admin password is so I uncommented the admin_password from the docker-compose.yaml file and ran docker-compose up and I am still not able to log in to my instance.

Thank you for any help!

Try resetting the password, using instructions on #81
you have to bash to the web container and run the command through Django shell

Thank you, I had to figure out how to bash into the web container, but once I did everything worked great!
