aws-cdk-eks-sample

A sample CDK application to create a sample Amazon EKS cluster.

install AWS CDK CLI

npm i -g aws-cdk

sample

create a default eks clsuter in a new vpc with 2 x m5.large for the managed nodegroup.

cdk deploy

create a default eks clsuter in the default vpc

cdk deploy -c use_default_vpc=1

create a default eks clsuter in a specific VpcId

cdk deploy -c use_vpc_id=vpc-xxxxxx

Managed Nodegroup

When you specify spot_only=1, you will get a spot managed nodegroup diversified and distributed with predefined instance types : t3.large, c5.large and m5.large.

create spot-only managed nodegroup

cdk deploy -c spot_only=1

(Node: you don't have to specify spotPrice)

specify different instance type for a on-demand managed nodegroup.

cdk deploy -c instance_type=t3.large

specify different capacity

cdk deploy -c default_capacity=3

(this will create 3 x m5.large instances)

Advanced Usage

This will create 1 x t3.large spot instance in the default vpc for the Amazon EKS

npx cdk deploy \
-c use_default_vpc=1 \
-c spot_only=1 \
-c default_capacity=1 \
-c instance_type=t3.large
