What I'm trying to do and why

Save a database that is inside a docker container, while borgmatic runs outside of the container.

Proposed change

Add a new section in https://torsion.org/borgmatic/docs/how-to/backup-your-databases/ that includes the fix of @Firesphere in #495 where a user can expose to a port on the same machine at ip localhost to avoid exposing it to a wider audience, with this snippet as a concrete example of docker-compose section:

version: '3'
services:
  db:
    image: mariadb:latest
    volumes:
      - mariadb-data:/var/lib/mysql
    environment:
      - MYSQL_RANDOM_ROOT_PASSWORD=1
    env_file:
      - .env
    ports:
      - "127.0.0.1:3307:3306"

and the corresponding borgmatic configuration snippet:

hooks:
    mysql_databases:
        - name: posts
          hostname: 127.0.0.1
          port: 3307
          username: root
          password: trustsome1
          options: "--skip-comments"

Then hostname is just set to 127.0.0.1, and port to 3307.
