Ruby on Rails is a server-side web application framework that allows web designers and developers to implement dynamic, fully featured web applications.
Deploying the Ruby on Rails Marketplace App
The Linode Marketplace allows you to easily deploy software on a Linode using the Linode Cloud Manager.
Log in to the Cloud Manager and select the Marketplace link from the left navigation menu. This displays the Linode Compute Create page with the Marketplace tab pre-selected.
Under the Select App section, select the app you would like to deploy.
Fill out all required Options for the selected app as well as any desired Advanced Options (which are optional). See the Configuration Options section for details.
Complete the rest of the form as discussed within the Getting Started > Create a Linode.
Click the Create Linode button. Once the Linode has provisioned and has fully powered on, wait for the software installation to complete. If the Linode is powered off or restarted before this time, the software installation will likely fail. To determine if the installation has completed, open the Linode’s Lish console and wait for the system login prompt to appear.
Follow the instructions within the Getting Started After Deployment section.
Software installation should complete within 2-5 minutes after the Linode has finished provisioning.
Ruby on Rails Options
You can configure your Ruby on Rails App by providing values for the following fields:
|Rails Application name||The name for your rails application. Required.|
For advice on filling out the remaining options on the Create a Linode form, see Getting Started > Create a Linode. That said, some options may be limited or recommended based on this Marketplace App:
- Supported distributions: Debian 9
- Recommended minimum plan: All plan types and sizes can be used.
Getting Started after Deployment
Access Ruby on Rails
After Ruby on Rails has finished installing, you will be able to access Ruby on Rails from the console via ssh with your Linode’s IPv4 address:
Log out and log back in as your limited user account.
Update your server:
sudo apt-get update && apt-get upgrade
Ruby comes with some pre-made scripts to get you started. One of these is a blog. To begin with the blog example, use the following command:
rails new blog
This creates a new Rails application called Blog in the
Move into the
Start the built in server with the following command, replacing the IP address with your Linode’s IP address:
rails server --binding=198.51.100.0
Warning: Running `gem pristine --all` to regenerate your installed gemspecs (and deleting then reinstalling your bundle if you use bundle --path) will improve the startup performance of Spring. => Booting WEBrick => Rails 22.214.171.124 application starting in development on http://198.51.100.0:3000 => Run `rails server -h` for more startup options => Ctrl-C to shutdown server [2020-03-11 14:17:16] INFO WEBrick 1.3.1 [2020-03-11 14:17:16] INFO ruby 2.3.3 (2016-11-21) [x86_64-linux-gnu] [2020-03-11 14:17:16] INFO WEBrick::HTTPServer#start: pid=3089 port=3000
You can visit your application by visiting the address in the browser.
Exit the server process with Ctrl+C.
Create a Controller and View
A controller will receive requests which are then routed and served by various actions. A view displays information.
Create a controller called
Welcomeand an action called
rails generate controller Welcome index
With the text editor of your choice, edit the file
app/views/welcome/index.html.erband replace the contents with the following:
- File: app/views/welcome/index.html.erb
<h1>Hello, World! This is Ruby on Rails!</h1>
Tell Rails where to find the document root. Edit the file
config/routes.rb, find and uncomment the line root as shown:
- File: config/routes
Rails.application.routes.draw do get 'welcome/index' ... root 'welcome#index' ... end
Start the server again:
rails server --binding=198.51.100.0
You should see your new welcome page in the web browser.
For more information on setting up a more substantial application, refer to the Ruby on Rails Getting Started Guide.
NoteCurrently, Linode does not manage software and systems updates for Marketplace Apps. It is up to the user to perform routine maintenance on software deployed in this fashion.
