POPEYE

PYJava

Making five services written in four different languages live together, in a single command.

A distributed voting application serves as the support: a site to vote, a queue, a worker processing the votes, a database and a real-time results site. Each brick is written in a different language. The work consists in packaging them and making them talk, with strict network partitioning between them.

Containerising a voting application into five services (Flask, Redis, Java worker, PostgreSQL, Node/Socket.IO) orchestrated by docker-compose over three isolated networks.
