EKS Cluster Config Generator (eksctl)

The EKS Cluster Config Generator writes a eksctl ClusterConfig so you can spin up an Amazon EKS cluster without memorising the schema. You set the cluster name, region and Kubernetes version, then describe a node group with instance type and autoscaling bounds.

The output is valid eksctl YAML with a managed node group. Names are validated as RFC 1123 labels. Everything runs locally - nothing is uploaded and no cluster connection is made.

• eksctl schema - correct ClusterConfig v1alpha5.
• Node groups - instance type and capacity.
• Autoscaling - desired, min and max size.
• Validation - RFC 1123 cluster and node group names.
• Copy / Download / Print - get cluster.yaml wherever you need it.

1. Name the cluster and pick a region + version.
2. Describe the node group (instance type, capacity).
3. Watch the preview and export.

Example 1 - default. 1x m5.large, 3 nodes.

Example 2 - autoscaling. min 2, max 6, desired 3.

• Correct schema - valid eksctl ClusterConfig.
• Validated - names and versions checked.
• Clean output - empty fields omitted.
• Private - everything runs in the browser.
• Copy, download or print - get the manifest where you need it.
