cdk-eks-app

easily manage and automate eks with aws cdk.

prerequisites

• aws cli
• aws cdk cli
• node & npm
• kubectl

get started

install required dependencies:

npm i

bootstrap your cdk (if not already done yet):

cdk bootstrap

deploy the resources:

cdk deploy

give it some time to deploy the cluster and other related resources.

once it's deployed, copy the output that starts with aws eks update-kubeconfig. it should look something like:

aws eks update-kubeconfig --name demogo --region <region> --role-arn <role-arn>

this will allow you to access the cluster directly via kubectl.

now, port forward nginx svc on local port 8080 to test it:

kubectl port-forward svc/nginx 8080:80

finally visit localhost:8080 and voila - you should see nginx running!

making changes

on a new terminal, activate ts compiler watch mode:

npm run watch

check diff generated:

cdk diff

deploy the resources:

cdk deploy

clean up

destroy the app and resources:

cdk destroy
