Estoy creando la aplicación Django, y funciona bien en mi máquina, pero cuando ejecuto dentro del contenedor docker, su marco de descanso sigue fallando, pero cuando comento cualquier conexión con el marco de descanso, funciona bien.
salida de error:

En su archivo docker, configura la imagen como python:rc-alpine3.14 que usa python 3.10. Teniendo en cuenta que 3.10 se lanzó recientemente, muchos de los paquetes aún no se han actualizado y, según las restricciones de versión que tenga en su requirements.txt eso también podría causar versiones incompatibles. El problema aquí es que Django Rest framework usa el paquete de solicitudes que usa collections.MutableMapping , si escribo esto en python 3.9, recibo la siguiente advertencia que dice que esto se eliminará en 3.10, por lo tanto, debe cambiar por ahora a 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 ¡Otra cosa sobre escribir python:rc-alpine3.14 ya que la imagen solo pide que su código se rompa! Especifique una versión estable y lanzada específica en lugar del candidato de lanzamiento rc :
