AwsInstanceList

Welcome to your new gem! In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file lib/aws_instance_list. To experiment with that code, run bin/console for an interactive prompt.

This gem is an easy way to get AWS instance list in all regions. The class AwsIntanceList::List runs one Thread by region to get the data in each one. Finally join all in one Array.

Using the AWS describe instance we can get the instances but the metrics are not available.

Add this line to your application's Gemfile:

gem 'aws_instance_list'

And then execute:

$ bundle

Or install it yourself as:

$ gem install aws_instance_list

As a library you need require it after install the gem.

require 'aws_instance_list'

list= AwsInstanceList::List.new

# sample to get all rds instances

list.db_list # will return an array like this

# db_instance_identifier, engine, storage (GBytes), status, free storage available, region

#\>
[
["db1", "mysql", 50, "available", 45.3829460144043, "eu-west-1"],
["db2", "mysql", 50, "available", 44.111881256103516, "eu-west-1"],
["db3", "mysql", 20, "available", 15.590309143066406, "eu-west-2"],
["db4", "mysql", 100, "available", 94.48283767700195, "eu-west-2"]
]

Add a test.env file with:

DB_INSTANCE_IDENTIFIER=identifier_name_db
REGION=aws_region_to_test # sample: eu-central-1
LONG_REGION=aws_region_with_pagination_to_test # sample: eu-west-1

And run

rspec

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.
