CodePudding user response：
Either you can downgrade your python version. That should solve your problem if not, then,use collections.abc.Mapping instead of deprecated collections.Mapping.
Refer here: Link
CodePudding user response：
In your docker file you set the image as python:rc-alpine3.14 which uses python 3.10. Considering that 3.10 is very recently released, many of the packages are yet to upgrade and depending on the version constraints you have in your requirements.txt that might also cause incompatible versions. The problem here is Django Rest framework uses the requests package which is using collections.MutableMapping, if I write this in python 3.9 I get the following warning which says this will be removed in 3.10, hence you should downgrade for now to python 3.9:
Warning (from warnings module):
File "<pyshell#1>", line 1
DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated since Python 3.3, and in 3.10 it will stop working
Another thing about writing python:rc-alpine3.14 as the image is just asking for your code to break! Specify a specific stable and released version rather than the release candidate rc:
FROM python:3.9.7-alpine3.14
