Easy way to connect to ec2 instance in office behind proxy and at home

AWS ec2 instances normally have both public DNS name and public IP address. We can wisely use them for office environment which may behind proxy and directly connect from home.

Set below code in .ssh/config and enjoy convenience.

Suppose the instance has name as

ec2-54-252-146-85.ap-southeast-2.compute.amazonaws.com
54.252.146.85

So you can set as below

How to run use "bazaarvoice/cloudformation-ruby-dsl" to generate cloudformation template

I was recommended to use github repository bazaarvoice/cloudformation-ruby-dsl to generate cloudformation template. But its README is not good enough.

Here are the steps on how to use it on my mac with bundler

$ git clonehttps://github.com/bazaarvoice/cloudformation-ruby-dsl.git
$ cd cloudformation-ruby-dsl
$ bundle install
$ bundle exec rake -T
rake build          # Build cloudformation-ruby-dsl-1.0.4.gem into the pkg directory
rake install        # Build and install cloudformation-ruby-dsl-1.0.4.gem into system gems
