eksctl is a simple CLI tool for creating clusters on EKS – Amazon’s new managed Kubernetes service for EC2. It is written in Go, uses CloudFormation, was created by Weaveworks and it welcomes contributions from the community.
eksctl create cluster
A cluster will be created with default parameters
- ∙ exciting auto-generated name, e.g. “fabulous-mushroom-1527688624”
- ∙ 2x m5.large nodes (this instance type suits most common use-cases, and is good value for money)
- ∙ use official AWS EKS AMI
- ∙ us-west-2 region
- ∙ dedicated VPC (check your quotas)
- ∙ using static AMI resolver
Customize your cluster by using a config file. Just run:
eksctl create cluster -f cluster.yaml
to apply a cluster.yaml file:
apiVersion: eksctl.io/v1alpha5
kind: ClusterConfig
