Example Api built with Python Eve and running with Docker

This project is an example of how I build microservice APIs quickly.

Steps to run

*Assuming you have git, docker, and docker-compose

git clone git@github.com:taemon1337/api-boilerplate.git
cd api-boilerplate/
docker-compose up

./docker-compose.yml

version: '2'
services:
  api:
    build: ./api
    volumes:
      - ./api:/api
    working_dir: /api
    command: python -u run.py
    environment:
      - MONGO_HOST=mongo
      - MONGO_PORT=27017
      - MONGO_DB=apidb
    ports:
      - 8080:8080
  mongo:
    image: mongo
    volumes:
      - ./data/mongo:/data/db

./api/Dockerfile

The API docker image is python with eve installed.

FROM: python:slim
RUN pip install eve

./api/run.py

The API is basically the Python Eve schema definition and runtime config.
