Ansible 2 Cloud Automation Cookbook

By: Aditya Patawari, Vikas Aggarwal

Overview of this book

Ansible has a large collection of inbuilt modules to manage various cloud resources. The book begins with the concepts needed to safeguard your credentials and explain how you interact with cloud providers to manage resources. Each chapter begins with an introduction and prerequisites to use the right modules to manage a given cloud provider. Learn about Amazon Web Services, Google Cloud, Microsoft Azure, and other providers. Each chapter shows you how to create basic computing resources, which you can then use to deploy an application. Finally, you will be able to deploy a sample application to demonstrate various usage patterns and utilities of resources.

Creating instance templates

Instance templates define various characteristics of an instance and related attributes. Some of these attributes are:

  • Machine type (f1-micro, n1-standard-1, custom)
  • Image (we created one in the previous tip, app-image)
  • Zone (us-west1-a)
  • Tags (we have a firewall rule for tag http)

How to do it...

Once a template is created, we can use it to create a managed instance group which can be auto-scale based on various parameters. Instance templates are typically available globally as long as we do not specify a restrictive parameter like a specific subnet or disk:

- name: create instance template named app-template
  gce_instance_template:
    name: app-template
    size: f1-micro
    tags: http,http-server...
