Ruby Applications

Containerized Ruby applications can be created and managed in OpenPanel Enterprise Edition.

Create an Application​

To create a new Ruby application, navigate to OpenPanel > AutoInstaller and click Setup Ruby Application.

On the next page, you can configure the following settings:

• Name – The name of the application and container as displayed in OpenPanel.
• Port – Set a custom port if your app uses one. Otherwise, port 80 is used by default.
• Domain Name / Subfolder – The domain (and optional subfolder) where the application will be publicly accessible.
• Startup File – The file executed at startup with the ruby command. Defaults to app.rb.
• Custom Startup Command – Use a custom startup command instead of the default ruby.
• Type – Fixed to Ruby.
• Version – Select any available Ruby version from Docker Hub's official ruby image tags.
• Run Install – Run bundle install using the Gemfile before starting the application. Skip this if your application is already built or has no gem dependencies.
• CPU Cores – Number of CPU cores allocated to the application.
• Memory – Amount of memory (in GB) allocated to the application.

After completing the form, click Start Installation. The installation process will be displayed below the form. Once complete, you’ll be redirected to the management page where you can view all your applications.

Example App​

A minimal Sinatra application.

Example app.rb file:

require 'sinatra'

set :port, 3000
set :bind, '0.0.0.0'

get '/' do
  'Hello World from Ruby on port 3000!'
end

Example Gemfile:

source 'https://rubygems.org'

gem 'sinatra'

Enable Run Install so bundle install runs before the app starts.

Manage Applications​

Once your application is created, you can manage it from OpenPanel > Site Manager.

Click Manage next to the application name to open its management page.

On this page, you can view important details such as:

• Screenshot – Preview of the application’s domain.
• Status – Current container status.
• Version – Ruby version in use.
• CPU Limit – Configured CPU allocation.
• Memory Limit – Configured memory allocation.
• Speed – Google PageSpeed Insights data for the website.
• Files – Current folder path and size.
• Firewall – WAF (Web Application Firewall) status for the domain (if enabled).

You also have several management options:

• Actions – Start, stop, or restart the container.
• Overview – Modify startup file or command, working directory, package installation settings (Bundler), version, and resource limits (CPU, Memory, PIDs).
• Install Packages – View and manage the Gemfile, and run bundle install.
• Logs – View container logs for troubleshooting.
• Remove – Delete the application.
