title: Giving Docker access to db file outside container
body: <p>I'm trying to test a Django app managed by Docker. Since it's a development project only used by me, I'm using a sqlite3 database backend. However, because I'll be populating this test database with a lot of generated data, and because I don't fully trust Docker, I want to store this sqlite3 db file outside of the container in my home directory, to ensure it doesn't get deleted or lost.</p>
  
  <p>However, by design, Docker makes it difficult for programs inside containers to access files outside of those containers. How do I update my Docker configuration to allow access to this one specific db file in my home directory?</p>
