EXPOSE-server is the heart of EXPOSE.
It consists of various programmes that are containerised in a single Docker container and then deployed to machines all over the world using Fly.io.
These different programs are :
- An SSH server in Python,
- A Node.js program that acts as an intermediary between the SSH server and the Web server, as well as between remote Web resources and programs in the container,
- A Web server built on OpenResty.
