Django/Docker: error in path for serving templates - django

Question

I try to "dockerize" a Django project.
I've already dockerized a Django project ; I've tried to use the exactly same project architecture.
I have first config dev environnement.
I buil/run the 2 containers (web and db): OK.
I migrate: OK
When I try to collectstatic I got an error
FileNotFoundError: [Errno 2] No such file or directory: '/usr/src/app/core/static'
and that right, static folder is at the same level as core app.
As I config dev environnement, with Django web server, I don't have to care about serving static files. So I've try to acces localhost:8000 and got an error:
That means I have an error in path config but I can find where as I replicate the same structure...

The BASE_DIR is referring to app/core, so you need to adjust the TEMPLATES directories as below:
'DIRS': [
os.path.join(BASE_DIR,'registration/templates'),
os.path.join(BASE_DIR,'monitor/templates'),
os.path.join(BASE_DIR,'randomization/templates'),
os.path.join(BASE_DIR,'unblind/templates'),
os.path.join(BASE_DIR,'pharmacy/templates'),
os.path.join(BASE_DIR,'export/templates'),
os.path.join(os.path.dirname(BASE_DIR,'templates')),
],
