docker-microservices

Overview

• Developed a code evaluation tool for code exercises
• Project is following testdriven.io
• Built, tested, and deployed microservices with Flask, React, Docker, nginx, gunicorn

Purpose

• Practice test-driven development (TDD)
• Try to implement the twelve-factor app pattern
• Microservice architecture, separation of concerns
• Setup staging and production environments with AWS Lambda, EC2, ECS
• Swagger service to document API
• Continuous integration with Travis CI
  • Run tests and flake8

Run Application

Scripts

# Build Images
docker-compose -f docker-compose-dev.yml up build

# Build Containers
docker-compose -f docker-compose-dev.yml up -d

# Stop Containers
docker-compose -f docker-compose-dev.yml up stop

# Down Containers
docker-compose -f docker-compose-dev.yml up down

# Remove Images
docker rmi $(docker images -q)

# staging -> docker-compose-stage.yml
# production -> docker-compose-prod.yml

Create docker host with docker machine

docker-machine create -d virtualbox {name}
docker-machine env {name}
eval $(docker-machine env {name})

# get docker machine ip
docker-machine ip {name}    

Tips

Create aliases for docker-compose and docker-machine

Add the following lines to .bashrc file

alias dc='docker-compose'
alias dm='docker-machine'

then, source ~/.bashrc

Access the database

docker exec -ti {container_name} psql -U postgres -W
\c {db_name}
select * from {table_name}
