docker-deploy

Deploy your code to any Docker servers

About

This script provides a super simple way of deploying your projects onto remote Docker hosts by only utilizing rsync, SSH, and docker-compose.

Requirements

• An application folder with a docker-compose.yml file
• SSH access to a taret Linux (Centos, Ubuntu) server
• Docker Machine on local

What it does

docker-deploy lets you deploy your stack in a single command without any of the fuss. All you really need is just a working application folder with a docker-compose.yml file inside it and a target server with SSH access. If the target server doesn't have Docker (or docker-compose) installed, it will even install it for you!

Usage

./docker-deploy [project_folder] [docker_server]

Example

• Let's say ~/Projects/site.com is my local dev environment and it has a docker-compose.yml file
• And I have SSH access to jae@server.com which has Docker installed
• Simply run this to deploy your project to your target Docker server

cd ~/Projects
docker-deploy site.com jae@server.com

What does it do?

The docker-deploy script is simply a wrapper around a couple bash scripts. Basically it does the following:

• rsync -avzr ./site.com jae@server.com:~/sites/site.com
• ssh jae@server.com "cd ~/sites/site.com && docker-compose up -d"

That's it!

Simple, right? Sometimes, I feel people tend to over-engineer and deployment is one of those areas. Unless you are serving Google-traffic, this deployment style will work fine for most of your projects. Hope you enjoy it.

For Virtual Hosting

I am often surprised to come across those who have not yet realized the power of jwilder/proxy. If you have multiple websites you want to host, then you should definitely consider having jwilder/proxy running on your Docker server listening to your port 80.

docker run -d -p 80:80 -v /var/run/docker.sock:/tmp/docker.sock:ro jwilder/nginx-proxy

Then in the docker compose file, simply assign an environmental variable called VIRTUAL_HOST with the hostname you wish to host. Take a look at the docker compose file below to see what I mean.

docker-compose.yml

Here is how my typical docker-compose.yml looks:

php

app:
image: jaequery/php
command: /start.sh
environment:
- VIRTUAL_HOST=site.app,site.jaequery.com
restart: always
volumes:
- .:/web
tty: true

ruby

app:
image: jaequery/honeybadger
links:
- db:honeybadger-postgres
command: /init_container.sh
environment:
- VIRTUAL_HOST=honeybadger.app,honeybadger.jaequery.com
restart: always
db:
image: postgres
environment:
- POSTGRES_PASSWORD=j
restart: always

Tip

• You may want to place docker-deploy script to your /usr/local/bin for global access
