Lab Assistant Manager

Overview

Provides a web-based interface for managing lab assistants. Allows TAs to configure seections for lab assistants to sign up for along with facilitating the check in process.

Branch Organization:

• master - is the main branch, storing the current code all non-course specific features should be branched from.
• cs61a - is the master branch for the CS61A course lab assistant manager instance.
• cs61b - is the master branch for the CS61B course lab assistant manager instance.
• data8 - is the master branch for the DATA8 course lab assistant manager instance.

How to contribute:

• Fork the repository. If you are not used to github have a look at fork a repository
• Create a branch either from master (or a specific course branch if this is a 1 course only feature).
• Add your features and commit your desired changes.
• Create a pull request detailing your changes creating pull requests.

Installation

1. Set up VirtualBox, Vagrant & Homestead

   Download and install virtual box: https://www.virtualbox.org/wiki/Downloads

   Download and install vagrant: https://www.vagrantup.com/downloads.html

   Install the Homestead Vagrant Box: vagrant box add laravel/homestead

   Install Homestead

   cd ~
   git clone https://github.com/laravel/homestead.git Homestead
   # Clone the desired release...
   git checkout v6.1.0
   
   # If on Mac / Linux...
   bash init.sh
   
   # If on Windows...
   init.bat
   

   Update Homestead.yaml to point to where you are cloning this repo. E.g:

   folders:
       - map: ~/Projects/Check-In
         to: /home/vagrant/Code/Check-In
   
   sites:
       - map: la.local
         to: /home/vagrant/Code/Check-In/public
         php: "5.6"
   

   Append the following lines to after.sh:

   # Install MySQL Server, PHP 5.6 and required packages
   sudo apt update
   sudo apt install -y mysql-server php5.6-common php5.6-cli php5.6-curl php5.6-fpm php5.6-mbstring php5.6-mcrypt php5.6-mysql php5.6-xml
   
   # Use PHP5.6 as system default PHP
   sudo update-alternatives --set php $(which php5.6)
   
   # Change any PHP7 references in Nginx sites
   sudo sed -i -E 's/php7[.0-9]*?/php5.6/g' /etc/nginx/sites-available/*
   
   # Change PHP5.6 FPM to run under vagrant user (necessary for writing data to Check-In folder)
   sudo sed -i -e 's/www-data/vagrant/g' /etc/php/5.6/fpm/pool.d/www.conf
   
   # Reload config changes
   sudo service nginx restart
   sudo service php5.6-fpm restart
   

2. Set up your hosts file

   You must add the "domains" for your Nginx sites to the hosts file on your machine. The hosts file will redirect requests for your Homestead sites into your Homestead machine. On Mac and Linux, this file is located at /etc/hosts. On Windows, it is located at C:\Windows\System32\drivers\etc\hosts. The lines you add to this file will look like the following:

   192.168.10.10  la.local
   

   Make sure the IP address listed is the one set in your Homestead.yaml file. Once you have added the domain to your hosts file and launched the Vagrant box you will be able to access the site via your web browser:

   http://la.local

3. Set up environment variables

   cd ~/Projects/Check-In
   # Copy the example environment variable file to .env
   cp env.example .env
   # Edit .env as necessary
   vim .env # or with your editor of choice
   

4. Start the Vagrant instance

   cd ~/Homestead
   vagrant up
   

5. SSH into the Vagrant instance

   vagrant ssh
   # Set working directory to project location
   cd ~/Code/Check-In
   

6. In SSH: Install dependencies using composer (PHP package manager)

   composer install
   

7. In SSH: Run the database migrations

   php artisan migrate
   

8. In SSH: Seed the database with initial values

   php artisan db:seed --class DefaultSettingsSeeder
   

9. In SSH: Generate an application key

   php artisan key:generate
   

10. Write the codestuffs

    Point your browser to http://la.local.

    Edit files in ~/Projects/Check-In as necessary

11. Stop the VM when you're done working

    vagrant halt
    

Post-Installation

The next time you want to start working again, simply start the Vagrant instance again

vagrant up

And stop it when you're done

vagrant halt

If you change the sites or maps inside of Homestead.yaml you will need to run the following to update Vagrant:

vagrant reload --provision

Deployment

First point a git remote to the Dokku server (the example below is CS61A specific):

git remote add dokku [email protected]:la

To deploy from master:

git push dokku master

Deploy from another branch:

git push dokku my_branch:master

First Time Deployment

Note: These are deployment instructions to the CS61A managed Dokku platform. They should be generic enough to follow to deploy to your own Dokku instance however.

Tip: add alias dokku="ssh -t [email protected]" to your aliases file (e.g. ~/.bashrc).

dokku apps:create app-name
git remote add online [email protected]:<app_name>
dokku mysql:create db-name
dokku mysql:link db-name app-name
# Set DNS record
dokku domains:add app-name name.cs61a.org

# Get the APP KEY
dokku enter <app_name> web php artisan key:generate

dokku config:set app-name APP_KEY=<KEY COPIED FROM key:generate command> APP_ENV=prod OK_COURSE_OFFERING="cal/cs61a/fa17" APP_OAUTH_KEY=<SECRET> APP_URL="https://mydomain.com" FORCE_HTTPS=true MAIL_DRIVER=mailgun MAIL_GUN_DOMAIN=<MAIL_GUN_DOMAIN> MAIL_GUN_SECRET=<MAIL_GUN_SECRET>
MAIL_HOST=<MAIL_HOST> MAIL_PORT=<MAIL_PORT> MAIL_USERNAME=<MAIL_USERNAME> MAIL_PASSWORD=<MAIL_SECRET> MAIL_ENCRYPTION=null
dokku letsencrypt app-name
# Change OK OAuth to support the domain

# Run migrations after following steps in Deployment
dokku enter <app_name> web php artisan migrate --force
dokku enter <app_name> web php artisan db:seed --class=DefaultSettingsSeeder --force

Note: when setting course offering, make sure it is exact. "cal/cs61a/fa17" is not the same as "cal/cs61a/fa17/"!
