Docker provides docker-compose rather than relying on shell scripts. Q: Shall we write a shell script and execute a docker process on our local machine for both containers?Ī: No. We then log into it and configure it as if it were running locally. Don’t we need a container for Postgres?Ī: We do not need to configure a Postgres container as Docker provides a docker image for Postgres which we can just start up. Q: But the container above runs only Django. configures it for us to run things on top of it by installing required packages and copying over our Django project code.copies the full project directory into it.installs python packages (no virtualenv needed in the container to begin with).creates a /code directory at root level.The remaining set of instructions in lines 3-7: This option asks the terminal not to use buffering. Same for output data and error data ( stdout and stderr). At that point it dumps the entire chunk of data into your application all at once. The terminal keeps data in a reservoir until a size limit or a certain character (generally a newline or EOF) is reached. What is this? Normally, if you have a process piping data into your application, the terminal may buffer the data. Line 2 sets environment variable PYTHONUNBUFFERED to 1.

run gunicorn or uwsgi as “ glue” between the framework (Django code) and the webserver.

directly run runserver command, which is what should be done for debugging purposes.

For the purposes of this proof-of-concept, I used Docker Desktop.

Put a breakpoint and debugged the code!.

Run Django in a Docker container on the same dev box.

Why would you want to run Django inside a Docker locally? Don’t you have enough moving parts needed to run things already?
