mgfs

mgfs is a FUSE filesystem which uses MongoDB GridFS as a storage backend.

Installation

You need to have Golang installed. Open your terminal, and run go get github.com/amsa/mgfs. Now you should be able to run mgfs (be sure to add $GOPATH/bin to your $PATH).

How to use

First mount your MongoDb database: mgfs test /path/to/mount/dir. You may now go to the directory specified as the mount point, and see the collections (directories), and documents (json files). You may read, update, or delete the documents. You may also read and delete GridFs files under the specified prefix (fs by default).

Don't forget to unmount the database when you are done (umount /path/to/mount/dir).

Caveats

There is no caching layer implemented in-process or externally (eg. Redis or Memcached). As long as MongoDB is close to your FUSE process latency wise, you should have no issues. PRs are welcome to implement caching if there is interest :)

Working locally on the codebase

Make any code changes required
test.sh will put you in a shell in a container, with access to MongoDB (it runs docker-compose up -d within test.sh)
./app -a $MONGODB_HOST -p 27017 -b databasename -m mountpoint/
