Making cloudformation suck less.

Because plums are also peaches

Add this line to your application's Gemfile:

gem 'sumomo'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sumomo

This gem lets you use all of the syntax in the momo and more!

You need to setup your AWS credentials using aws configure.

This is the simplest way to use sumomo:

First, create a file called Sumomofile in your directory

# Sumomofile
x = hidden_value "meow"
eip = make "AWS::EC2::EIP"
output "IPAddress", eip
output "Haha", x

To create a stack that acquires an IP Address and outputs it

$ sumomo create mystack

To view a stack's outputs

$ sumomo outputs mystack

To update a stack

$ sumomo update mystack

To delete a stack

$ sumomo delete mystack

To view what changes your stuff will cause to your stack

$ sumomo diff mystack

To see the raw cloudformation template

$ sumomo show mystack

The commandline tool actions can also be performed programmatically

require "sumomo"

Sumomo::update_stack(name: "mystack", region: "ap-northeast-1") do
	x = hidden_value "meow"
	eip = make "AWS::EC2::EIP"
	output "IPAddress", eip
	output "Haha", x
end

Sumomo::wait_for_stack(name: "mystack", region: "ap-northeast-1")

You can make a server

network = make_network(layers: %w[web])
eip = make "AWS::EC2::EIP"

make_autoscaling_group(
  network: network,
  layer: 'web',
  eip: eip,
  type: "a1.medium",
  vol_size: 15, # GB,
  script: <<-SCRIPT
      yum install git gcc g++
      echo "hello world" >> ~/hello
  SCRIPT
)

output 'IP', eip

You can make apis with this now

api = make_api "test2.astrobunny.net",
    name: "TestGenAPI",
    cert: certificate,
    dns: cloudflare_dns(key: key, email: email) do

    GET "/page/:pageid", :pageid, <<-SCRIPT
        respond_with ({message: pageid, params: params});
    SCRIPT

    GET "/best_girl", <<-SCRIPT
        respond_with ({best_girl_is: "Ruby"});
    SCRIPT

    GET "/*", <<-SCRIPT
        respond_with ({message: "Hello!"});
    SCRIPT

end

output "APIURL", api

You can test your API now

$ sumomo testapi -a TestGenAPI

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
