test devops task to init local env for cloud development - k8s or docker-swarm

Task

Given simple counter application that uses Redis as a backend storage to keep the persistent counter.

API:

GET / - returns current counter number
POST /increment - increments the counter
DELETE /increment - resets the counter

Run configuration:

server.py - main application entrypoint. Server can be started via command: pipenv run python server.py

Dependencies

• All the python dependencies MUST be installed via pipenv
• Application uses Redis as a backend storage

Expectations

• Dockerfile is provided as application run environment
• Application running in Docker Swarm / Kubernetes stack / etc. (feel free to choose orchestrator)
• Stack can be deployed locally running single bash script / command (prerequisites provided if something needs to be installed)
• Application is located behind load-balancer and can be reachable via domain name from host (e.g. http://counter-app.local)
• Application is scalable and fault tolerant (killing single node will not result into application is down)
• Application can be easily configured via ENV variables (feel free to propose updates into application if needed)
