Simple Rails deploy bash script

deploy.sh

#!/bin/bash

# deploy.sh

# Put this script on your production server and make it executable with chmod
# +x. 

# Set the deploy_dir variable to the path on the production server to
# deployment directory. The script assumes the deployment directory is a git
# clone of the codebase from an upstream git repo. This script also assumes
# you are using Passenger.

deploy_dir=~/current # deploy dir

# You then can run deploy.sh  remotely with ssh:
#
#     ssh user@deployserver "~/deploy.sh"


echo "=======> Deploying to $deploy_dir <========"
cd $deploy_dir && git stash && git pull   

# Run migrations if any are pulled down
if find db/migrate -type f -mmin -3 | grep '.*'
then
  echo New migrations found
  RAILS_ENV=production bundle exec rake db:migrate

fi

# Uncomment if using ThinkingSphinx
# RAILS_ENV=production bundle exec rake ts:rebuild


# Restart if any new Rails code
if find app config lib db/migrate -type f -mmin -3 | grep '.*'

  echo Restarting Rails
