Vlad the Deployer is a tool for deploying Ruby on Rails applications. It automates many of the steps required to deploy a Rails application, making it faster and easier to deploy your application to production. In this tutorial, we will show you how to install Vlad the Deployer on NixOS Latest.
Before we begin, make sure you have the following prerequisites:
To install Vlad the Deployer, we need to add the vlad package to our NixOS system. To do this, open a terminal and run the following command:
$ sudo nix-env -iA nixos.vlad
This command will install Vlad the Deployer on your system.
Next, we need to configure Vlad the Deployer to work with our Rails application. We will create a deploy.rb file in our Rails application directory and add the following code:
require 'vlad'
set :application, 'my_app'
set :repository, 'git@github.com:myusername/my_app.git'
set :deploy_to, '/var/www/my_app'
role :app, "my_app.com"
role :web, "my_app.com"
role :db, "my_app.com", :primary => true
set :user, "deploy"
set :scm, :git
set :branch, "master"
set :deploy_via, :remote_cache
Make sure to replace my_app with the name of your Rails application and myusername with your Github username.
Now that Vlad the Deployer is installed and configured, we can deploy our Rails application to production. To do this, simply run the following command in your Rails application directory:
$ vlad deploy
Vlad the Deployer will take care of the rest and deploy your application to production.
In this tutorial, we showed you how to install and use Vlad the Deployer to deploy your Ruby on Rails application to production. With the right tools and a little know-how, deploying your Rails application to production can be a breeze.
