Redis – Plugin caching_sha2_password could not be loaded: /mariadb19/plugin/caching_sha2_password.so: cannot open shared object file

I am trying to dockerise my Django app.

docker-compose.yml

version: "3.8"

services:
  db:
    image: mysql:8
    command: --default-authentication-plugin=mysql_native_password # this is not working
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: rootmypass
    ports:
      - '3306:3306'
  cache:
    image: redis
    environment:
      REDIS_HOST: localhost
      REDIS_PORT: 6379
    ports:
      - '6379:6379'
  web:
    build: .
    command: python manage.py runserver 0.0.0.0:8000
    volumes:
      - .:/code
    ports:
      - "8000:8000"
    depends_on:
      - db
      - cache

When I run docker-compose -up, I get the following error.

django.db.utils.OperationalError: (1156, 'Plugin caching_sha2_password could not be loaded: /usr/lib/x86_64-linux-gnu/mariadb19/plugin/caching_sha2_password.so: cannot open shared object file: No such file or directory')

Upon searching, I found the solution was to use command: --default-authentication-plugin=mysql_native_password or downgrade mysql. Tried the first command but it’s not working. I don’t want to downgrade as well.

How do I get it to work?

Additional details:

• Using Docker on Windows.
• Distro: Ubuntu 20.04 LTS (WSL2).
• Connector: mysqlclient==1.4.6.
