Providing a sample of uploading and downloading secure files from an S3 compatible object store

Most object stores we work with are S3 compatible, which is now the industry standard for defining object stores. Linode follows the same standard for their object store product offering.

The example will cover protected uploads and downloads via signed urls, this can later be extend to publicly available content. The example should offer samples:

- A meta data table that stores the information about the uploaded file
- Signed URLs to upload content to an object store
- Signed URLs for downloading objects from the store
- Related the uploaded content to the User object
- Use MinIO to wrap the calls and provide a local server to simulate uploads (requires providing a Docker setup for the development server)

Provide documentation on how to use this in the application
