Creating Kubernetes clusters with Terraform

Articles in this series

In this series, you will get started with infrastructure as code (IaC) with Terraform.

By the end of each article, you will build strong confidence in provisioning Kubernetes clusters through tutorials and code examples.

Provision production-ready Kubernetes clusters

Imagine provisioning a Kubernetes cluster through a web interface such as the AWS Management console.

There are plenty of configuration options and screens that you have to complete before using the cluster.

When you create the cluster manually, can you be sure that:

You did not forget to change one of the parameters?
You can repeat precisely the same steps while creating a cluster for other environments?
When there is a change, you can apply the same modifications in sequence to all clusters without any mistake?

The process is error-prone and doesn't scale well if you have more than a single cluster.

A better option is defining a file containing all the configuration flags and using it as a blueprint to create the cluster.

And that's precisely what you can do with infrastructure as code tools such as Terraform.

At Learnk8s, we've prepared an in-depth guide designed to help you:

Use Terraform to provision your cluster.
Create a configuration that includes an Ingress (so your cluster is actually functional).
Parametrise the code so that you can create several clusters for different environments.

All of the articles have code snippets, so you can start building your production-ready cluster.
