I try to "dockerize" a Django apps.
All works fine except static files that are not served.
I use Django web server (dev) so I should not have to "served" static files.
Neverthelsess, I run docker exec -it coverage_africa_web_1 python manage.py collectstatic command
and get the confirmation
You have requested to collect static files at the destination
location as specified in your settings:
/usr/src/app/static
This will overwrite existing files!
Are you sure you want to do this?
Type 'yes' to continue, or 'no' to cancel: yes
Found another file with the destination path 'randomization/js/script.js'. It will be ignored since only the first encountered file is collected. If this is not what you want, make sure every static file has a unique path.
140 static files copied to '/usr/src/app/static'.

Answer 1

I see that you don't use a web server to serve the static files, so make sure that Django is serving the static files.
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
# ... the rest of your URLconf goes here ...
] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
have a look to to Django documentation https://docs.djangoproject.com/en/3.1/howto/static-files/#serving-static-files-during-development

Answer 2

OK, missing settings
STATIC_URL = '/static/'
# STATIC_ROOT = os.path.join(BASE_DIR, "static") <- removed in dev
STATICFILES_DIRS = (
os.path.join(BASE_DIR, "static"), <- added in dev
os.path.join(BASE_DIR,'randomization_management/static'),
os.path.join(BASE_DIR,'randomization_settings/static'),
os.path.join(BASE_DIR,'randomization/static'),
)
