Description
suggestion by @iamacup on the community channel
useful for application bootstrapping (initial data). import data from a mounted directory.
postgres is doing that:
downside: more complexity in the dockerfile (while it could easily be implemented in a derived docker image)
upside: very convenient and very beginner friendly
needs discussion
