dockerized-example-services

This repo is a sample app showing how to dockerize Scala microservices in a monorepo.

The solution consists in a simple common library containing shared type definitions, a producer service pulling status updates from Twitter and pumping those, every one second, to a consumer web app through Rabbit hole, cough..I mean, queue. The web app renders the incoming status data in real time.

Development

This solution uses a pure FP approach, a bunch of streams, and some of the greatest libraries in the FP Scala ecosystem like:

1. cats
2. cats-effects
3. fs2
4. http4s
5. fs2-rabbit

Try it out locally

Note: This project relies on having Docker installed on your system

1. Clone this repo and cd into it

$ git clone git@github.com:nebtrx/dockerized-example-services.git

$ cd  dockerized-example-services

2. Build the project and create the containers' images

$ sbt docker:publishLocal

5. Copy the sample configuration file and edit it to match your configuration so your docker can pick up the env vars

$ cp .env.example .env

4. Create and start the containers

$ docker-compose up

5. Check http://localhost:8080/stream on your browser and watch the magic take place

6. Optionally, you can check http://localhost:15672 to access rabbitmq console
