Feed Feeder

Checks RSS feeds for changes and saves new items to your database. Uses PubSubHubbub where possible otherwise polls every specified interval. This is used at Lateral to power the news recommendations of NewsBot.

Initializing

Run the setup script to install dependencies, create databases and all that jazz:

bin/setup

Running

The main components to the application are the rails server, resque and resque-scheduler. To start them all for development (after installing foreman gem install foreman) run:

foreman start

For production the services should each be started separately and kept alive through something like systemd. For example with:

Feed Feeder - /etc/systemd/system/ff.service

[Unit]
Description=Feed Feeder
After=multi-user.target

[Service]
User=ubuntu
WorkingDirectory={PROJECT_DIR}
ExecStart={PROJECT_DIR}/bin/puma --tag feed-feeder -e production -b tcp://0.0.0.0:9292
Restart=always

[Install]
WantedBy=multi-user.target

Resque - /etc/systemd/system/[email protected]

[Unit]
Description=Resque #%i
After=multi-user.target

[Service]
User=ubuntu
Environment=RAILS_ENV=production QUEUE=*
WorkingDirectory={PROJECT_DIR}
ExecStart={PROJECT_DIR}/bin/rake -f {PROJECT_DIR}/Rakefile environment resque:work
Restart=always
RuntimeMaxSec=28800

[Install]
WantedBy=multi-user.target

Resque Scheduler - /etc/systemd/system/ff-resque-scheduler.service

[Unit]
Description=Resque Schdeduler
After=multi-user.target

[Service]
User=ubuntu
Environment=RAILS_ENV=production
WorkingDirectory={PROJECT_DIR}
ExecStart={PROJECT_DIR}/bin/rake -f {PROJECT_DIR}/Rakefile environment resque:scheduler
Restart=always
RuntimeMaxSec=28800

[Install]
WantedBy=multi-user.target

And then running (untested):

sudo systemctl enable ff.service
sudo systemctl enable ff-resque@@{1..5}.service
sudo systemctl enable ff-resque-scheduler.service
sudo systemctl start ff.service
sudo systemctl start ff-resque@@{1..5}.service
sudo systemctl start ff-resque-scheduler.service
