# Using Docker for local development
|
|
|
|
You can use Docker to have a local Consul Democracy installation for development if:
|
|
|
|
- You're having troubles having [prerequisites](prerequisites.md) installed.
|
|
- You want to do a quick local installation just to try Consul Democracy or make a demo.
|
|
- You prefer not to interfere 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
|
|
```
|
|
|
|
### Windows
|
|
|
|
Go to the [https://www.docker.com/get-started](Get Started with Docker) page. Under Docker Desktop, select Download for Windows with default options checked, and run. Should take about 5 minutes.
|
|
|
|
If you encounter the "WSL 2 installation incomplete" error:
|
|
|
|
1. Start PowerShell as Administrator
|
|
1. Run `dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart`
|
|
1. Run `dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart`
|
|
1. Install [WSL2 Linux kernel update package for x64 machines](https://wslstorestorage.blob.core.windows.net/wslblob/wsl_update_x64.msi)
|
|
1. Run `wsl --set-default-version 2`
|
|
1. Restart your PC
|
|
1. The Docker Enginer will start up. Give it a few minutes. You now have the option of using the docker desktop app (GUI) and `docker` PowerShell/Bash commands
|
|
|
|
## Installation
|
|
|
|
Clone the repo on your computer and enter the folder:
|
|
|
|
```bash
|
|
git clone https://github.com/consuldemocracy/consuldemocracy.git
|
|
cd consuldemocracy
|
|
```
|
|
|
|
### 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
|
|
POSTGRES_PASSWORD=password docker-compose build
|
|
```
|
|
|
|
Start the database service:
|
|
|
|
```bash
|
|
POSTGRES_PASSWORD=password docker-compose up -d database
|
|
```
|
|
|
|
You can now initialize your development DB and populate it with:
|
|
|
|
```
|
|
POSTGRES_PASSWORD=password docker-compose run app rake db:create db:migrate
|
|
POSTGRES_PASSWORD=password docker-compose run app rake db:dev_seed
|
|
```
|
|
|
|

## Running local Consul Democracy with Docker
|
|
|
|
### macOS & Linux
|
|
|
|
Now we can finally run the application with:
|
|
|
|
```bash
|
|
POSTGRES_PASSWORD=password 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
|
|
POSTGRES_PASSWORD=password 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 Democracy's directory**, to erase all your previous Consul Democracy's Docker images and containers. Then restart the Docker [installation process](#installation):
|
|
|
|
1. Remove all Consul Democracy images:
|
|
|
|
```bash
|
|
docker-compose down --rmi all -v --remove-orphans
|
|
```
|
|
|
|
2. Remove all Consul Democracy 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>
|
|
```
