+# FLASK MICROSERVICES
+
+This project is based on [testdriven.io](http://testdriven.io/) Microservices with Docker, Flask and React  
+
+### Structure
+1. _[flask-microservices-main](https://github.com/repodevs/flask-microservices-main)_ Docker Compose files, Nginx, admin scripts
+2. _[flask-microservices-users](https://github.com/repodevs/flask-microservices-users)_ Flask App
+3. _[flask-microservices-client](https://github.com/repodevs/flask-microservices-client)_ client-side based on ReactJS
+---
+
+## How To Run
+----
+### Build for Local 
+1. create docker-machine for local (with virtualbox driver)
+```bash
+$ docker-machine create --driver virtualbox dev
+```
+2. activate docker-machine 
+```bash
+$ eval $(docker-machine env dev)
+```
+3. Build the images and spin up the containers
+```bash
+$ docker-compose up -d --build
+```
+4. create and seed the db then run the tests
+```bash
+$ docker-compose run users-service python manage.py recreate_db
+$ docker-compose run users-service python manage.py seed_db
+$ docker-compose run users-service python manage.py test
+```
+
+Test it by opening your browser [http://0.0.0.0:80](0.0.0.0:80) or [http://0.0.0.0:80/users](0.0.0.0:80/users) 
+
+---
+### Build for Production 
+
+1. create docker-machine for production (with driver digitalocean based on ubuntu 14.04)   
+```bash
+$ docker-machine create --driver digitalocean --digitalocean-access-token=DO_TOKEN --digitalocean-image ubuntu-14-04-x64 prod
+```
+2. activate docker-machine   
+```bash
+$ eval "$(docker-machine env prod)"
+```
+3. Build the images and spin up the containers
+```bash
+$ docker-compose -f docker-compose-prod.yml up -d --build
+```
+4. create and seed the db then run the tests
+```bash
+$ docker-compose -f docker-compose-prod.yml run users-service python manage.py recreate_db
+$ docker-compose -f docker-compose-prod.yml run users-service python manage.py seed_db
+$ docker-compose -f docker-compose-prod.yml run users-service python manage.py test
+```
+5. watch the logs
+```bash
+$ docker-compose logs -f users-service
+```
+6. grab ip
+```bash
+$ docker-machine ip prod
+```
+
+Test it by opening your browser [http://YOUR_PROD_IP:80](YOUR_PROD_IP:80) or [http://YOUR_PROD_IP:80/users](YOUR_PROD_IP:80/users) 
+
+----
+## Other Commands
+
+To stop Docker container:
+```bash
+$ docker-compose stop
+```
+To bring down the container:
+```bash
+$ docker-compose down
+```
+Force build:
+```bash
+$ docker-compose build --no-cache
+```
+Remove image:
+```bash
+$ docker rmi $(docker images -q)
+```
+---
+Access database via psql:
+```bash
+$ docker exec -ti users-db psql -U postgres -W
+```
+
