s3signer

s3signer

A simple web service to return S3 signed URLs.

Usage

$ curl http://localhost:8080/mybucket/myfile/
https://s3-us-west-1.amazonaws.com/mybucket/myfile?AWSAccessKeyId=RANDOMLETTERS&Expires=1234567890&Signature=MORERANDOMLETTERS

The signed URLs returned are valid for 5 seconds.

Configuration

Configuration is via environment variables. The the goamz.aws.EnvAuth variables need to be provided, and s3signer uses one additional variable AWS_REGION to specify the region by name. Something like us-west-1, (as defined here).

Buckets, files

All buckets that the credentials have access to are cached on startup. If a new bucket is created, the service will need to be restarted. Files inside of buckets are searched for on each request.

Nested files in buckets are not supported at this time.
