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

Clone the repo on your computer and enter the folder:

git clone git@github.com:consul/consul.git
cd consul

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:

docker build -t consul .

Create your app database images:

docker-compose up -d database

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

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

Running local CONSUL with Docker

macOS & Linux

Now we can finally run the application with:

docker-compose up

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

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

docker-compose run app rails console

To verify the containers are up execute:

docker ps .

You should see output similar to this: docker ps

Having trouble?

Run these commands at Consul's directory, to erase all your previous Consul's Docker images and containers. Then restart the Docker installation process:

  1. Remove all CONSUL images:

    docker-compose down --rmi all -v --remove-orphans
    
  2. Remove all CONSUL containers

    docker-compose rm -f -s -v
    
  3. Verify if there is some container yet:

    docker ps -a
    

    Case positive, remove each one manually:

    docker container rm <container_id>
