Halcyon

Halcyon is a unified High Performance Computing (HPC) center operations portal. It allows for self-serve customer allocation purchase and management, account management, a knowledge base, customer relations management (CRM), and more.

Underlying Framework

Halcyon utilizes Laravel, a web application framework with expressive, elegant syntax. Laravel takes the pain out of development by easing common tasks used in many web projects.

Minimum System Requirements

To be able to run Halcyon you have to meet the following requirements:

Server Requirements

• PHP >= 8.1 or higher
• Ctype PHP Extension
• cURL PHP Extension
• DOM PHP Extension
• Fileinfo PHP extension
• Filter PHP Extension
• Hash PHP Extension
• JSON PHP Extension
• Mbstring PHP Extension
• OpenSSL PHP Extension
• PDO PHP Extension
• Session PHP Extension
• Tokenizer PHP Extension
• XML PHP Extension

Database Requirements

• MySql 5.6+ or MariahDB 10.1+

Extensions

Extensions typically consist of modules, widgets, listeners (plugins), and themes.

Modules

Modules are found in /app/Modules and can be thought of as relatively self-contained apps. These can have their own functionality, database tables, interfaces, console commands, and more. Examples include a forum, a store, etc. For further information on creating modules, see the official Laravel Modules documentation.

Note: The referenced documentation above places modules in ./Modules. In Halcyon, they're found in ./app/Modules. Aside from location, all other documentation should still apply.

Widgets

Widgets are found in /app/Widgets and are small bits of code that can be injected in different locations on a theme or page-by-page basis. Some widgets are linked to modules, displaying information specific to or feeding information to that module. An example of this would be a "Report a problem" widget that presents a form on every page for creating an entry in a support ticketing module. However, widgets do not need to be linked to modules; they can be just static HTML or text.

Listeners

Listeners (a.k.a., plugins) are found in /app/Listeners. Listeners can enhance data and provide additional functionality by executing code in response to certain events. Events serve as a way to decouple aspects of an application, since a single event can have multiple listeners that do not depend on each other. An example may be a listener that sends a notification to Slack when someone places a new order.

Themes

Themes are found in /app/Themes. A theme controls the presentation of the content. The theme is the basic foundation design for viewing the website.

Structure

Below is an example of the location and typical directory structure typical extensions to the system:

Install

Clone the repo.

git clone git@github.com:PurdueRCAC/halcyon.git .

Move into the directory.

cd halcyon

Docker

Modify the database configuration in config/database.php or .env. If you are using Docker the DB_HOST name will be the container name of the MySQL service.

NOTE: You can copy .env.example and rename it to .env which will have many of the variables pre-filled.

This will perform the Composer install and initial database migration (found under the manual setup).

docker-compose up

Install needed libraries

docker exec -it halcyon-php-fpm php /var/www/html/bin/composer install --prefer-dist

Run the initial setup script

docker exec -it halcyon-php-fpm php /var/www/html/bin/composer run-script initial-setup

This should complete the setup as it runs through all the individual artisan commands listed below. However if you make changes/add Modules, etc. the individual commands to launch the appropriate artisan command via Docker are listed below.

Run migrations to install tables and base data.

docker exec -it halcyon-php-fpm php artisan migrate
docker exec -it halcyon-php-fpm php artisan module:migrate

Create a symlink from the file storage to a publicly accessible spot. This will create a symlink for ./public/files to ./storage/app/public.

docker exec -it halcyon-php-fpm php artisan storage:link

Publish assets.

docker exec -it halcyon-php-fpm php artisan module:publish
docker exec -it halcyon-php-fpm php artisan theme:publish
docker exec -it halcyon-php-fpm php artisan listener:publish

Manual

Run Composer to install dependencies.

php ./bin/composer install --prefer-dist

Modify the database configuration in config/database.php or .env.

Run migrations to install tables and base data.

php artisan migrate
php artisan module:migrate

Create a symlink from the file storage to a publicly accessible spot. This will create a symlink for ./public/files to ./storage/app/public.

php artisan storage:link

Publish assets.

php artisan module:publish
php artisan theme:publish
php artisan listener:publish

Git Hooks

The repo contains some useful git hooks for development.
