This Redmine plugin makes file attachments be stored on “Amazon S3” rather than on the local filesystem.

1. Make sure Redmine is installed and cd into its root directory

2. Add the plugin to the Gemfile

3. Configure S3 access (see below for options)

4. Restart/upload to production/whatever

This method should be preferred when using Heroku.

AWS_ACCESS_KEY_ID

Your AWS access key ID

AWS_SECRET_ACCESS_KEY

Duh, your AWS secret access key

AWS_S3_BUCKET

Bucket (and optional path prefix)

Use this method if you have no control over your environment variables.

1. Copy GEM_ROOT/config/s3.yml.example to RAILS_ROOT/config/s3.yml

2. Edit config/s3.yml with your favourite editor

• The bucket name can contain an optional path prefix, e.g. a setting of “foo/bar/baz” will upload attachments under “foo.s3.amazonaws.com/bar/baz/”.

• Uploaded files are NOT public.

• The bucket is NOT created upon startup if it doesn’t exist.
