The Email service "sends" an email to the customer with their order details by rendering it as a log message. It expects a JSON payload like:

{
  "email": "some.address@website.com",
  "order": "<serialized order protobuf>"
}

We use bundler to manage dependencies. To get started, simply bundle install.

You may run this service locally with bundle exec ruby email_server.rb.

From src/email, run docker build .
