Kubernetes in Production Best Practices

By: Aly Saleh, Murat Karslioglu

Overview of this book

Although out-of-the-box solutions can help you to get a cluster up and running quickly, running a Kubernetes cluster that is optimized for production workloads is a challenge, especially for users with basic or intermediate knowledge. With detailed coverage of cloud industry standards and best practices for achieving scalability, availability, operational excellence, and cost optimization, this Kubernetes book is a blueprint for managing applications and services in production. You'll discover the most common way to deploy and operate Kubernetes clusters, which is to use a public cloud-managed service from AWS, Azure, or Google Cloud Platform (GCP). This book explores Amazon Elastic Kubernetes Service (Amazon EKS), the AWS-managed version of Kubernetes, for working through practical exercises. As you get to grips with implementation details specific to AWS and EKS, you'll understand the design concepts, implementation best practices, and configuration applicable to other cloud-managed services. Throughout the book, you’ll also discover standard and cloud-agnostic tools, such as Terraform and Ansible, for provisioning and configuring infrastructure. By the end of this book, you’ll be able to leverage Kubernetes to operate and manage your production environments confidently.

Cleaning up and destroying infrastructure resources

After completing the hands-on exercises in this chapter, you can follow the instructions in this section to destroy the Kubernetes cluster and its AWS resources.

You will destroy the resources in reverse order from their creation. First, you will destroy the Kubernetes cluster resources, then the VPC resources, and finally the shared state resources.

Destroying the cluster resources

Follow these Terraform commands to destroy all of the packtclusters resources that you created in the previous sections of this chapter:

  1. Initialize the Terraform state:
    $ cd Chapter03/terraform/packtclusters
    $ terraform init
  2. Execute the terraform destroy command. Enter yes when you get a prompt to approve the destruction:
    $ terraform destroy
  3. You will get the following output once the terraform destroy command completes successfully. This means that Terraform has successfully destroyed the 22 resources in the cluster:
