ruby on rails - Getting started with delayed jobs -

-

i using ror , mongodb. application deployed on heroku. want run few delayed jobs on amazon ec2. came across commands 

git pull on repo. chmod 600 xyz.pem ssh -i xyz.pem ubuntu@ec2-234-33-37-14.compute-1.amazonaws.com

i have worked heroku not ec2 , if can point me resources or explain getting started setup of dealyed_job in amazon ec2.

things know:
1) how implement delayed jobs in code.

things don't know , have doubts:
1) how setup new machine on amazon ec2 have rails repo?
2)how run delayed_jobs connecting app mongo database in heroku.?

1) how setup new machine have rails repo?

you can automatically configure new machine in number of ways. popular ways puppet/chef/saltstack.

for simple setup, might want run script. aws allows supply script (via userdata) when launching machine. https://help.ubuntu.com/community/cloudinit

here example of userdata script might supply aws:

#!/bin/sh  set -e -x  apt-get --yes --quiet update apt-get --yes --quiet install git  git clone https://github.com/user/repo.git /destination/folder

2) how run delayed_jobs connecting app mongo database?

documentation can found here: https://github.com/collectiveidea/delayed_job

delayed jobs

call .delay.method(params) on object , processed in background.

# without delayed_job  @user.activate!(@device)  # delayed_job  @user.delay.activate!(@device)

mongo

if plan use delayed_job mongoid, add delayed_job_mongoid gemfile.

gem 'delayed_job_mongoid'
