Base Sinatra App for Summer Institute

This app is meant as a base Passenger app that runs in an OnDemand portal that uses the Sinatra web framework for OSC's Summer Institute.

Feel free to modify it anyway you see fit.

Deploy

The directions below require Ruby and Bundler be installed and accessible from the command line. At OSC we use modules, so you'll need to issue this command to load the right ruby environment.

$ module load ruby/3.1.4

1. To deploy and run this app you will need to first go to your OnDemand sandbox directory (if it doesn't exist, then we create it):

   $ mkdir -p ~/ondemand/dev
   $ cd ~/ondemand/dev

2. Then clone down this app and cd into it:

   $ git clone https://github.com/OSC/summer-institute-base-web-app.git blender
   Cloning into 'blender'...
   $ cd blender

3. Setup the app before you use it:

   $ bin/setup
   
   ...

4. Now you should be able to access this app from OSC OnDemand at https://ondemand.osc.edu/pun/dev/blender/

   Note: You may need to replace the domain above with your center's OnDemand portal location if not using OSC.

Develop

Development instructions are in the docs/ folder.

• Here's the link to develop a Blender app

Locally develop

While this application is meant to be used at OSC during Summer Institute you can develop this app on your own time on your own machine.

The one caveat being that you can't submit jobs to a scheduler from your local machine. You can however, use this application to continue to learn about Ruby, Sinatra, HTML and more!

Simply hop into a shell of your choosing, navigate to the directory of this application and issue the command bin/start. You should see output similar to what's given below.

Now you can connect to the application through http://localhost:9001. Note that you can change the port in the bin/start script as it's given as the first arguement -p9001.

$ bin/start
