gcsfuse Driver for Docker

This repo implements a Docker driver for gcsfuse. There are many like it, but this one is mine.

This plugin focuses on:

• Facilitating the creation of many volumes that use (different subdirs of) the same GCS bucket. Some existing Docker drivers seem to map gcsfuse processes to buckets; if trying to mount a subdir of the same bucket, multiple mounts would use the same gcsfuse process, which might cause its caching to thrash with enough load.
• Enough logging/monitoring to aid debugging in a production setting

Usage

TODO: This section is a work-in-progress.

1. Build and run gcsfuse_docker:

   go build ./cmd/gcsfuse_docker
   sudo ./gcsfuse_docker --v=1 --alsologtostderr
   

2. Test a mount with a Docker container:

   docker run \
     -it \
     --mount "type=volume,src=foobar,dst=/gcsfuse_test,volume-driver=gcsfuse,volume-opt=opt1=foo,volume-opt=opt2=bar" \
     ubuntu \
     /bin/bash
   

   TODO: Clarify the parameters in the mount string
