+# Using Docker for local development
+
+You can use Docker to have a local CONSUL installation for development if:
+- You're having troubles having [prerequisites](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](https://docs.docker.com/docker-for-mac/install/)
+
+Or if you have [homebrew](http://brew.sh) and [cask](https://caskroom.github.io/) installed you can just:
+
+```bash
+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:
+```bash
+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
+```bash
+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:
+```bash
+git clone git@github.com:consul/consul.git
+cd consul
+```
+### macOS & Linux
+
+Then lets create our secrets and database config files based on examples:
+
+```bash
+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:
+```bash
+docker build -t consul .
+```
+
+Create your app database images:
+
+```bash
+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:
+```bash
+docker-compose up
+```
+
+And you'll be able to access it at your browser visiting [http://localhost:3000](http://localhost:3000)
+
+Additionally, if you want to run the rails console just run in another terminal:
+
+```bash
+docker-compose run app rails console
+```
+
+To verify the containers are up execute:
+```bash
+docker ps .
+``` 
+You should see output similar to this:

+
+## 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](#installation):
+
+1. Remove all CONSUL images:
+```bash
+docker-compose down --rmi all -v --remove-orphans
+```
+
+2. Remove all CONSUL containers
+```bash
+docker-compose rm -f -s -v
+``` 
+
+3. Verify if there is some container yet:
+```bash
+docker ps -a 
+```
+Case positive, remove each one manually:
+```bash
+docker container rm <container_id>
+```
