How to clear cache for Django with Docker?
As per this answer you can add a service that's executed before the memcached service that clears out the cache. As it looks like you're using Linux Alpine, you can add this service to docker-compose.yml:
clearcache: command: [sh, -c, "python manage.py clear_cache"] and then add to memcached:
memcached: ... depends_on: - clearcacheThere's also an example in there that does it in the same command and not relying on a separate service (though personally I don't like that).
For the cache clearing command, this answer has some useful discussion and posts.
clear_cache.py:
from django.core.management.base import BaseCommandfrom django.core.cache import cacheclass Command(BaseCommand): def handle(self, *args, **kwargs): cache.clear() self.stdout.write('Cleared cache\n')
