S3 plugin for Redmine


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 it's root directory

  2. git clone git:// vendor/plugins/redmine_s3

  3. cp vendor/plugins/redmine_s3/config/s3.yml.example config/s3.yml

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

  5. Restart mongrel/upload to production/whatever

  6. Optional: Run 'rake redmine_s3:files_to_s3' to upload files in your files folder to s3

Options Overview

  • The bucket specified in s3.yml will be created automatically when the plugin is loaded (this is generally when the server starts).

  • Deprecated (no longer supported, specify endpoint option instead) If you have created a CNAME entry for your bucket set the cname_bucket option to true in s3.yml and your files will be served from that domain.

  • After files are uploaded they are made public, unless private is set to true.

  • Public and private files can use HTTPS urls using the secure option

  • Files can use private signed urls using the private option

  • Private file urls can expire a set time after the links were generated using the expires option

Options Detail

  • access_key_id: string key (required)

  • secret_access_key: string key (required)

  • bucket: string bucket name (required)

  • endpoint: string endpoint instead of

  • secure: boolean true/false

  • private: boolean true/false

  • expires: integer number of seconds for private links to expire after being generated

  • Defaults to private: false, secure: false, default endpoint, and default expires
