Southwest Checkin 2.0

Build Status Coverage Status

Automatically checks in passengers for their Southwest Flight.

Version 2.0 of this project is a complete rewrite of the service. The brittle HTML parsing and form submissions are a thing of the past. A much better approach is being taken to automate checkins. And, importantly, the new version has a robust test suite. It is even written in a new language (Ruby) and framework (Rails).

If you are interested in the old version, see the 1.0 branch.

curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
apt-get update
apt-get install -y nodejs git git-core nano unzip postgresql postgresql-contrib postgresql-server-dev-9.5 redis-server tmux autoconf bison build-essential libssl-dev libyaml-dev libreadline6-dev zlib1g-dev libncurses5-dev libffi-dev libgdbm3 libgdbm-dev

rbenv doesn't provide any installer, so we have to get use the source from Github. So, we need to clone it in our home directory. Then add to PATH

git clone https://github.com/sstephenson/rbenv.git ~/.rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
git clone https://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build

** Restart your shell ** Now we need to install Ruby 2.2.1

apt-get install build-essential libssl-dev libcurl4-openssl-dev libreadline-dev -y
rbenv install 2.2.1 -k
rbenv global 2.2.1
gem install rails --version 4.2.10
gem install bundler

Grab the source for checkin

git clone https://github.com/flyize/southwest-checkin.git
cd southwest-checkin

Install the bundled gems

bundle install

Create a db user and give them create privileges (ignore any directory errors)

sudo -u postgres createuser root
sudo -u postgres psql -c 'ALTER USER root CREATEDB'
# this fixes db encoding
sed -i -e 's/*default/*default\n  template: template0/g' config/database.yml

Populate the db

rake db:create db:migrate db:seed

Create a config file replace your website, email, and email server. It must accept mail on port 587 with tls.

echo 'SITE_NAME=Southwest Checkin
SITE_URL=http://mywebsite.com
ASSET_HOST=http://mywebsite.com
MAILER_DEFAULT_FROM_EMAIL=email@mywebsite.com
MAILER_DEFAULT_REPLY_TO=email@mywebsite.com
DEPLOY_BRANCH=master
DEPLOY_USER=deploy
DEPLOY_PORT=22
MAILER_ADDRESS=mail.mywebsite.com
MAILER_DOMAIN=mywebsite.com
MAILER_USERNAME=email@mywebsite.com
MAILER_PASSWORD=mypassword
MAILER_DEFAULT_HOST=
DEPLOY_DOMAIN=
DEPLOY_TO=
DEPLOY_REPOSITORY=
DEPLOY_USE_RBENV=true
MAILER_DEFAULT_PROTOCOL=http
MAILER_DEFAULT_HOST=mywebsite.com' > .env

Create a script to launch everything

echo '#!/bin/sh
service postgresql restart
service redis-server restart
sleep 2
echo Starting rails
tmux new -s rails  -d
tmux send-keys  -t rails "cd /root/southwest-checkin/app" C-m
tmux send-keys  -t rails "/root/.rbenv/shims/rails s -b 0.0.0.0 -p 80 -e development" C-m
tmux new -s sidekiq -d
sleep 2
echo Starting sidekiq
tmux send-keys  -t sidekiq "cd /root/southwest-checkin" C-m
tmux send-keys  -t sidekiq "/root/.rbenv/shims/bundle exec sidekiq &" C-m' > /root/start.sh

Make it executable

chmod +x /root/start.sh

Make the script run on boot

sed -i -e 's|"exit 0"|removed|g' /etc/rc.local
sed -i -e 's|exit 0|/root/start.sh\nexit 0|g' /etc/rc.local

Disable apache (if apache is installed)

update-rc.d apache2 disable

Disable ipv6 (otherwise you will find issues with the mailer)

echo 'net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1' >> /etc/sysctl.conf
