title: Create mongodb container w default data
body: <p>What's the best practices creating a mongodb container in docker with default data (collections with documents)?</p>
  
  <p>I've found this other thread (<a href="https://stackoverflow.com/questions/33558506/how-to-create-a-mongo-docker-image-with-default-collections-and-data">How to create a Mongo Docker Image with default collections and data?</a>) that's creates another db-path and mounts it as a new volume. But it doesn't seems right to me cause aren't you ending up with unused paths and mounted volumes?</p>
  
  <p>Is there right/another way to do this?</p>
