Create Puppet modules using Classes

A Puppet module is a reusable unit of manifest code, similar to functions or methods in procedural languages. A Puppet module can be defined in either of the following ways:

  1. Using classes
  2. Using defined types

In this article, I’m going to explain how to create a Puppet module using Classes. A Puppet class can be considered to be a container for resources. It is defined once and selected by all nodes that need to make use of the prepared functionality. Each class represents a well-known subset of a system’s configuration.

Here is the syntax of the class.

1
 class name { type {‘name’: attribute => value, } type {‘name’: attribute => value, } }
First thing you need to do is to create directory structure for your module. It needs to be created under “modules” directory present in your Puppet home directory (on most of the systems, Puppet home directory is /etc/puppet)

Here are step by step instructions: Continue reading

Configure AWS EC2 instance using Boto

Amazon Web Services (AWS) supports almost all the services required to run an enterprise level data center. The most frequently used service is Amazon Elastic Cloud Computing (EC2).

In this article, I’ll try to cover some of the most widely used EC2 parameters to be configured using Boto. Undoubtedly, AWS provides a web console which is very user friendly and supports almost all the features. But having Boto in your armour is a real edge. Being a system or AWS administrator, you won’t rely on the console very much. Instead, it will be all scripting and scripting. That’s where Boto comes into picture.

Ok, so let’s get started. First things first, let’s launch a new EC2 instance using Boto.

In order to create and managed EC2 instance, you’ll need following minimum information with you

  1. AMI ID               (Image ID which will be used to launch a new instance)
  2. Security Group (Security group name which the new instance will be part of)
  3. Key Pair             (Key pair name which will be used to access the instance)
  4. Region                (Leave blank for default region)
  5. Instance Type   (There are many types to select from, like t1.micro, m1.small, m1.medium, etc.)

Let’s create a new instance using Boto by providing above details:

    1. Create a connection between Boto and EC2

        

   2. Create new instance

 

   3. The output returns the reservation id for that particular instance.
