Installation ============ gem install s3stream Configuration ============= Log into Amazon Web Services, and lookup your access key ID and secret. https://aws-portal.amazon.com/gp/aws/developer/account/index.html?action=access-key Here, I'll pretend that your access key is "ABCDEFGHIJKLMNOPQ" and your secret is "12345678901234567890abcde". Alright then... % echo 'AWSAccessKeyId=ABCDEFGHIJKLMNOPQ' > ~/.aws-credentials % echo 'AWSSecretKey=12345678901234567890abcde' >> ~/.aws-credentials % export AWS_CREDENTIAL_FILE=~/.aws-credentials - OR - % export AMAZON_ACCESS_KEY_ID='ABCDEFGHIJKLMNOPQ' % export AMAZON_SECRET_ACCESS_KEY='12345678901234567890abcde' - OR - % export AWS_ACCESS_KEY='ABCDEFGHIJKLMNOPQ' % export AWS_SECRET_KEY='12345678901234567890abcde' Usage ===== % s3stream fetch mybucket myfile.dat > /tmp/myfile.dat % s3stream store mybucket myfile.dat < /tmp/myfile.dat If you want to try uploading a bunch of data, but don't have any handy: % base64 /dev/urandom \ | head -c $((10 * 1024 * 1024)) \ | s3stream store mybucket 10mb.txt And if you want to get fancy: % cat \ <(s3stream fetch mybucket log0.log.gz | gunzip) \ <(s3stream fetch mybucket log1.log.gz | gunzip) \ | lzop -9 \ | s3stream store mybucket combined.log.lzo If you want to stream an upload in ruby: S3Stream::Upload.to(:s3object => s3object) do |stream| stream.write("abc") stream.write("123") end
