Divercity Devops challenge

Context

We have 2 services running under nodeJS, we want to deploy those services to allow our users to use them.

  • The first service service1 has two endpoints /data and /version, this service runs on port 3000.
  • The second service service2 has one endpoint /linked-data and runs under port 3001, service2 depends on service1.
  • service2 expects to get the link to service1 using env var called SERVICE_LINK, this will allow service2 to get the necessary data from service1.

Our goal

The goal from this challenge is to build a web service that allows the 3 endpoints under the same domain

Requirements

  • create a dockerfile for each service.
  • Use nginx as a reverse proxy to serve both services under the same hood like this :

    • /data and /version served from service1.

    • /linked-data servce from service2.

We noticed that service1 is always under heavy load so we decided to scale up and use two instances for it.

  • Update the nginx configuration to create a load balancer to serve service1.

  • Create a deployment script that build docker images, sets nginx custom configuration and serves the app.

Nice to have

It would be a plus if you :

  • Set up a monitoring solution with different metrics.
  • Set up an alarm service that sends an email whenver the status of the services are critical.

Deliverables

  • Fork this repo, update it with all configuration files and add to it a readme file with the instructions.

PS: you are not allowed to change the code of the two serivces.
