Connect to AWS Management Data in Ruby

Connect to AWS Management data in Ruby with ruby-dbi, dbd-odbc, and ruby-odbc.

The CData ODBC Driver for AWS Management makes it easy to integrate connectivity to live AWS Management data in Ruby. This article shows how to create a simple Ruby app that connects to AWS Management data, executes a query, and displays the results.

Create an ODBC Connection to AWS Management Data

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

To authorize AWSDataManagement requests, provide the credentials for an administrator account or for an IAM user with custom permissions:

  1. Set AccessKey to the access key Id.
  2. Set SecretKey to the secret access key.
  3. Set Region to the region where your AWSDataManagement data is hosted.

Note: Though you can connect as the AWS account administrator, it is recommended to use IAM user credentials to access AWS services.

Installing Ruby and Necessary Gems

If you do not have Ruby installed, refer to the Ruby installation page. With Ruby installed, you will need to install the ruby-dbi, dbd-odbc, and ruby-odbc gems:

gem install dbi gem install dbd-odbc gem install ruby-odbc

Create a Ruby App with Connectivity to AWS Management Data

Create a new Ruby file (for example: AWSDataManagementSelect.rb) and open it in a text editor. Copy the following code into your file:

#connect to the DSN require 'DBI' cnxn = DBI.connect('DBI:ODBC:CData AWSDataManagement Source','','') #execute a SELECT query and store the result set resultSet = cnxn.execute("SELECT PartitionKey, Name FROM NorthwingProducts") #display the names of the columns resultSet.column_names.each do |name| print name, "\t" end puts #display the results while row = resultSet.fetch do (0..resultSet.column_names.size - 1).each do |n| print row[n], "\t" end puts end resultSet.finish #close the connection cnxn.disconnect if cnxn

With the file completed, you are ready to display your AWS Management data with Ruby. To do so, simply run your file from the command line:

ruby AWSDataManagementSelect.rb Writing SQL-92 queries to AWS Management allows you to quickly and easily incorporate AWS Management data into your own Ruby applications. Download a free trial today!
