Using Docker for local development

You can use Docker to have a local CONSUL installation for development if:

• You're having troubles having prerequisites installed.
• You want to do a quick local installation just to try CONSUL or make a demo.
• You prefer not to interfer with other rails installations.

Prerequisites

You should have installed Docker and Docker Compose in your machine:

macOS

You can follow the official docker install

Or if you have homebrew and cask installed you can just:

brew install docker
brew install docker-compose
brew cask install docker
open -a docker

You'll be asked to give Docker app permissions and type your password, then you're set.

Linux

1. Install Docker:

sudo apt-get update
sudo apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D
sudo apt-add-repository 'deb https://apt.dockerproject.org/repo ubuntu-xenial main'
sudo apt-get update
apt-cache policy docker-engine
sudo apt-get install -y docker-engine

2. Install Docker Compose

sudo curl -o /usr/local/bin/docker-compose -L "https://github.com/docker/compose/releases/download/1.15.0/docker-compose-$(uname -s)-$(uname -m)"
sudo chmod +x /usr/local/bin/docker-compose

Installation

macOS & Linux

Then lets create our secrets and database config files based on examples:

cp config/secrets.yml.example config/secrets.yml
cp config/database-docker.yml.example config/database.yml

Then you'll have to build the container with:

sudo docker build -t consul .

Create your app database images:

sudo docker-compose up -d database

Once built you can initialize your development DB and populate it with:

sudo docker-compose run app rake db:create
sudo docker-compose run app rake db:migrate
sudo docker-compose run app rake db:seed
sudo docker-compose run app rake db:dev_seed

Running local CONSUL with Docker

macOS & Linux

Now we can finally run the application with:

sudo docker-compose up

And you'll be able to acces it at your browser visiting http://localhost:3000

Additionally, if you want to run the rails console just run in another terminal:

sudo docker-compose run app rails console

To verify the containers are up execute sudo docker ps . You should see output similar to this:
