Docker Scrapy Mailer

It's a simple Docker container that uses Scrapy library to grab and parse a website, generating parsable JSON file.

After that we bind the JSON with a Mako template, resulting in a dynamic mail content.

Finally, we send it according to the MAIL_TO informed environment variable.
