Managing Amazon EKS clusters can be done in multiple ways—from point-and-click in the AWS Console to fully scripted Infrastructure as Code (IaC). Select the method that aligns with your team’s skills, automation goals, and compliance requirements.

​
1. AWS Management Console

Create an EKS cluster directly in the AWS Console by navigating to Kubernetes (EKS), clicking Create cluster, and completing the forms for Cluster name, Networking, Node groups, and Permissions.
The console UI offers quick setup without writing code, but switching between IAM, VPC, EC2, and EKS tabs can be error-prone and difficult to reproduce at scale.
Pros and cons:

​
2. AWS CloudFormation

Define your EKS infrastructure as code using CloudFormation YAML/JSON or the AWS Cloud Development Kit (CDK).
  • CloudFormation templates: Hand-craft IAM roles, VPCs, subnets, security groups, and EKS resources.
  • AWS CDK: Write TypeScript, Python, Java, or .NET code that synthesizes into CloudFormation.

Parameterize your templates to spin up multiple clusters with consistent settings. Use Change Sets and drift detection to manage updates and rollbacks safely.

​
3. Terraform

Terraform uses declarative HCL to provision EKS clusters. Leverage community or official modules from the Terraform Registry and AWS IaC Blueprints for best practices out of the box.
Terraform state management is your responsibility. Configure a remote backend (e.g., S3 + DynamoDB) to lock state files and prevent concurrent modifications.

4. Other Tools and Services

Several third-party and community-driven tools can simplify EKS cluster provisioning:

No matter which path you choose, standardize on templates or scripts to ensure consistency and speed. In the next section, we’ll introduce lightweight tools for spinning up disposable test clusters in minutes.
