This document shows how to mount an AWS S3 bucket on Mac OS X using goofyfs.

The first three steps illustrate how to use goofys

1. Install goofyfs via brew

brew cask install osxfuse
brew install goofys

2. Create an empty directory as a mount point for the S3 bucket

mkdir -p ~/drat

3. Mount a prefix of an S3 bucket (note the colon)

goofys com-dnli-ngs-test:drat ~/drat

4. When you are done, unmount the bucket

umount ~/drat
ls ~/drat  # empty

The following steps are only included to highlight the functionality of goofys:

1. Verify that files are sync'ed to S3

echo "Test" > ~/drat/test.tmp
aws s3 cp s3://com-dnli-ngs-test/drat/test.tmp -

echo "Test 2" > ~/drat/test.tmp
aws s3 cp s3://com-dnli-ngs-test/drat/test.tmp -

2. Unmount the bucket - and the local directory is empty

umount ~/drat
ls ~/drat  # empty
aws s3 ls s3://com-dnli-ngs-test/drat/  # not empty

3. Re-mount the bucket - and the files are back

goofys com-dnli-ngs-test:drat ~/drat
ls ~/drat  # not empty

4. Remove local files - and they are also removed from S3

rm ~/drat/test.tmp
aws s3 ls s3://com-dnli-ngs-test/drat/  # empty

5. Unmount the bucket when you are done

umount ~/drat
ls ~/drat  # empty
