An example of how to use Google Cloud Storage with git-annex

git-annex-gcs.sh

# Initialize git and git-annex
$ mkdir annex-gcs-test
$ cd annex-gcs-test/
$ git init
Initialized empty Git repository in /Users/jterrace/annex-gcs-test/.git/
$ git annex init "my machine"
init my machine ok

# Set up AWS credentials
$ export AWS_ACCESS_KEY_ID="YOUR-KEY"
$ export AWS_SECRET_ACCESS_KEY="YOUR-SECRET"

# Create a remote called "cloud" that goes to Google Cloud Storage
$ git annex initremote cloud type=S3 encryption=none host=storage.googleapis.com port=80 bucket=jterrace-git-annex
initremote cloud (checking bucket...) (creating bucket in US...) ok
(Recording state in git...)

# Create a test file and add it to git annex
$ echo "test" > testfile.txt
$ git annex add testfile.txt 
add testfile.txt (checksum...) ok
(Recording state in git...)
$ git commit -a -m "trying test file"
[master (root-commit) 097e0c8] trying test file
 1 file changed, 1 insertion(+)
 create mode 120000 testfile.txt

# Ship the file off to the cloud
$ git annex move testfile.txt --to cloud
move testfile.txt (checking cloud...) (to cloud...) 
ok
