Simple Dropbox service backed by S3

The simplest possible dropbox service.

Install

Assuming you have your AWS credentials set up in ~/.aws/credentials as described in the docs, set up the S3 bucket, IAM user and access keys with:

$ bin/setup some-service-name
Setting up hdrop resource named hdrop-some-service-name
Creating stack..........
BUCKETNAME=hdrop-some-service-name-hdropbucket-zd1pjbdtae3e4
ACCESSKEY=AKIA...
SECRETKEY=7z+Wd5w1...

Create a Heroku app:

$ heroku create
Creating stark-river-4697... done, stack is cedar
http://stark-river-4697.herokuapp.com/ | git@heroku.com:stark-river-4697.git
Git remote heroku added

Set the parameters from above as config vars:

$ heroku config:set \
> BUCKETNAME=hdrop-some-service-name-hdropbucket-zd1pjbdtae3e4
> ACCESSKEY=AKIA...
> SECRETKEY=7z+Wd5w1...
Setting config vars and restarting stark-river-4697... done, v3
BUCKETNAME: hdrop-some-service-name-hdropbucket-zd1pjbdtae3e4
ACCESSKEY: AKIA...
SECRETKEY: 7z+Wd5w1...

Push your code:

$ git push heroku master
...

Use

Get a set of get and put URLs:

$ curl https://stark-river-4697.herokuapp.com
{
  "get": "https://hdrop-some-service-name-hdropbucket-zdpjvb2d9oe4.s3.amazonaws.com/f4064499-930a-4138-88aa-94cb8a945708?AWSAccessKeyId=AKIAJPZ4VTR2WP3DVUNQ&Expires=1401484596&Signature=IZPT5%2BLEGws68dVIiAmbngvAsHE%3D",
  "put": "https://hdrop-some-service-name-hdropbucket-zdpjvb2d9oe4.s3.amazonaws.com/f4064499-930a-4138-88aa-94cb8a945708?AWSAccessKeyId=AKIAJPZ4VTR2WP3DVUNQ&Expires=1401484596&Signature=7hfoidVxmYWxwrHNsXm1iPn86Ks%3D"
}

Upload your file with the put URL:

curl $your_put_url --upload-file path/to/file

Send the get URL to your best friend who gets the file with:

curl $get_url -o saved_file

The Signed URLs expire after 10 mins. You can change that. Of course.
