Guide: from development
to production using docker.

Development

You'll need:

• docker
• docker-machine
• docker-compose
• git
• pow
• dotenv.sh
• deploy.sh

Setup

Within your project you must have:

• a development.yml and production.yml for docker-compose
• optionally a Dockerfile
• a .env file with the variables needed for the application and other services
• a bin/start script for customized application startup

Choose a custom port with 5 digits to be assigned to your application. Remember to write it to your .env file.

Grab the IP for the docker-machine and setup a local development name with pow:

# ~/.pow/my-application

http://192.168.99.100:55001/

Use Git to version your project. The last commit hash will be used as version tag for the application.

deploy.sh

#!/usr/bin/env bash

# Production's username@hostname
remote=

# Application's name and path
name=
path=

version=$(git rev-parse HEAD)
version=${version:0:5}
archive=$version.tar.gz

git archive --format tar.gz -o $archive HEAD
scp $archive $remote:$path

ssh $remote <<SSH
cd $path
tar -xzf $archive
[ -f Dockerfile ] && docker build --tag $name:$version .
docker-compose down -f production.yml
docker-compose up -f production.yml
SSH

dotenv.sh

#!/bin/sh

if [ -s .env ]; then
  source .env
  export $(cut -d= -f1 .env)
fi
