This is a serverless app built with Docker. Read more in the Serverless Docker repository.
It consists of a simple entrypoint server that listens for HTTP requests. All of the other functionality of the app is run on-demand as Docker containers for each HTTP request:
- vote: The voting web app, as a CGI container that serves a single HTTP request.
- record-vote-task: A container which processes a vote in the background, run by the vote app.
- result: The result web app, as a CGI container.
