Questions about the tutorial

[masish]

I tried below tutorial.
https://docs.microsoft.com/en-us/azure/app-service/tutorial-custom-container?pivots=container-linux#code-try-16

when I tried working sample on locally, I encountered below error when executed command "docker run -it -p 8000:8000 appsvc-tutorial-custom-image"

However, tutorial is working without this command "python manage.py migrate".

I think that we don't need executing this command for this tutorial, so this execution not in the tutorial steps, right?
I understand "python manage.py migrate" is for preparing database tables for app.
If application use a database and need to execute the command, Should we define the execution of the command in the docker file?
