S3 file upload proxy using Nginx, complete with AWS authentication.

Create a .env file to hold your environment variables for Nginx. It should contain the following:

AWS_ACCESS_KEY_ID=YOURAWSACCESSKEYID
AWS_SECRET_ACCESS_KEY=YOURAWSSECRETACCESSKEY
S3_BUCKET_NAME=YOURS3BUCKETNAME

Using Docker, build the image.

$ docker build -t jamescmartinez/nginx-s3-upload .

After the image is built, create a container.

$ docker run -d -p 80:80 --env-file=.env jamescmartinez/nginx-s3-upload

Once the container is running, give it a try!

$ curl -T path/to/file/to/upload http://nginx-s3-upload.yourdomain.com/uploads/entity/property/filename.extension

The response will contain a header, X-File-URL, with the location of the file on your S3 bucket.

Issue a pull request and I will love you forever.
