Deploy with Terraform

Terraform is an open-source infrastructure as code software tool that provides an easy deployment of your infrastructure for installing Decidim.

Many providers are available (AWS, Heroku, DigitalOcean...). Check the Terraform registry to see how to use Terraform with your provider

Each Terraform deployment are stored in the deploy folder and sorted by providers

Feel free to add new deployments!

Availables deployments

Environment variables

Each provider will need a way to authenticate at their API. Make sure to set environment variables asked in the provider's documentation before using deployments.

  • To use Scaleway's provider
export SCW_ACCESS_KEY=<your_access_key>
export SCW_TOKEN=<your_scw_token>
export SCW_DEFAULT_PROJECT_ID=<id_of_your_project/organization>
  • To use DigitalOcean's provider
export DIGITALOCEAN_TOKEN=<your_do_token>
export SPACES_ACCESS_KEY_ID=<your_do_space_access_key>
export SPACES_SECRET_ACCESS_KEY=<your_do_space_secret_key>

How to deploy with Terraform?

Check the list of make commands in the Makefile. Each command corresponds to a provider and a specific need.

  • To deploy a new infrastructure with Scaleway
make deploy-scw

Setting up the application

You will need to do some steps before having the app working properly once you've deployed it:

  1. Open a Rails console in the server: bundle exec rails console
  2. Create a System Admin user:
email = <your email>
password = <a secure password>
user = email, password: password, password_confirmation: password)!
  1. Visit <your app url>/system and login with your system admin credentials
  2. Create a new organization. Check the locales you want to use for that organization, and select a default locale.
  3. Set the correct default host for the organization, otherwise the app will not work properly. Note that you need to include any subdomain you might be using.
  4. Fill the rest of the form and submit it.

You're good to go!

Running tests

This application has a functional testing suite. You can easily run locally the tests as following :

Create test environment database

make start-seeded-decidim
  • Dumped Decidim

An environment running the current Decidim version (from Gemfile) with real data dumped from an existing platform to simulate a Decidim bump version before doing in the real production environment.

make start-dumped-decidim

Warning : you need to get a psql dump on your local machine to restore it in your containerized database Warning2 : you need to set organization host to with the rails console

How to stop and remove it?
