Deploy Ruby Apps

How to deploy Ruby apps on eenos ?

This document will help you to deploy a ruby app on your eenos hosting control panel.  Eenos control panel is a modern hosting control panel designed for modern apps. 

Features Of Eenos Ruby App Management

Eenso control panel have the following wonderful features for easily managing ruby apps.

  • Manage unlimited Ruby app domains or subdomains
  • Ruby Version Selector 
  • Deploy Ruby on Rails  with one click

Every eenos Ruby  app have its on virtual environment.  So migration and transfer of  hosting accounts are easy.

To start deploying Ruby and Ruby On Rails app, login to your eenos control panel and go to the following Page:

Ruby -> Deploy Ruby Apps

Setup Ruby SandBox and Install Apps

Now you need to fill the simple form  as follows,

Choose Domain For Ruby or Rails App : Select a domain or  subdomain  for deploying a ruby app. This  is the website  url you are going to deploy the app.

Choose Ruby Version : Select a suitable version of Ruby distribution to setup the Sandbox virtual environment.

App Startup Script : This is the startup entry script name. It is normally a ruby script  ( eg : config.ru , app.ru ) 

Public Folder Name: This is the folder into which you upload the static files  like css, js, images, etc. It is directly under your website document root.

Project Publicity Type : This option will help you  to setup the project  in either production or development mode.

Install Demo App : If you wish to install  a sample Ruby on Rails app and if you have already developed the app, you can select the option no and upload the files yourself.

Installing demo Ruby on rails app may take some time. It is a time consuming job.You can view the progress from Ruby sandbox apps section.

Now, Click  the button  Deploy App and it will start deploying the app.

Manage Ruby App From Shell

If your hosting account have enabled ssh access,  you can easily manage your Ruby app from the shell. You may contact your hosting server  provider and enable the ssh shell  to access this feature. 

You can login to the server with the ssh client from your desktop.

Here, we are going to use the following details to show you how to manage Python app from eenos sever shell virtual environment. 

 Example eenos user :  myuser

Example python  app domain : ruby.mydomain.com

Example  eenos ssh sever port  : 22

Login to SSH terminal

Login to the ssh sever with the following command ,

ssh myuser@ruby.mydomain.com -p 22

Activate Ruby  Virtual Environment

Activate the Virtual Sandbox  Python environment for the domain ruby.mydomain.com as follows,

myuser:$ ~ $ source ~/.sandbox/ruby/ruby.mydomain.com/bin/activate
(ruby.mydomain.com) myuser:$ ~ $

Done, you are on the domains ruby environment , you can start working on your python app from the terminal. 

See some  example commands below,

Check Ruby version , gem version and rails version for the domain,

(ruby.mydomain.com) myuserd@u:$ ~ $ ruby -v
ruby 3.0.3p157 (2021-11-24 revision 3fb7d2cadc) [x86_64-linux]
(ruby.mydomain.com) myuser@u:$ ~ $ gem -v
3.2.32
(ruby.mydomain.com) myuser@u:$ ~ $ rails -v
Rails 7.0.2.3
(ruby.mydomain.com) myuser@u:$ ~ $

Install rack gem  on the domain as follows,

(ruby.mydomain.com) myuser@u:$ ~ $ gem install rack
Fetching rack-3.0.2.gem
Successfully installed rack-3.0.2
Parsing documentation for rack-3.0.2
Installing ri documentation for rack-3.0.2
Done installing documentation for rack after 9 seconds
1 gem installed
(ruby.mydomain.com) myuser@u:$ ~ $
(ruby.mydomain.com) myuser@u:$ ~ $ gem list | grep rack
rack (3.0.2, 2.2.3)
rack-test (1.1.0)
(ruby.mydomain.com) myuser@u:$ ~ $

Deactivate  Ruby Virtual Environment

You can deactivate the current working ruby shell virtual environment by using the following command,

(ruby.mydomain.com) myuser@:$ ~ $ deactivate 
myuser@:$ ~ $

This command will return you to the default terminal. Now you can switch to another ruby app from the same terminal

Switch Ruby SandBox Virtual Environment

If we have Flask app on the  domain chat.mydomain.com on the same eenos hosting account, we can switch to the virtual environment for the chat app as follows,

myuser:$ ~ $ source  ~/.sandbox/ruby/chat.mydomain.com/bin/activate
(chat.mydomain.com) myuser:$ ~ $

With the above steps you can start deploying ruby and ruby on rails apps.  The next session will help you to manage Ruby Gem modules from the eenos control panel.
