Create a AWS EKS cluster and deploy the tomcat as k8s pods.

Install AWS CLI, eksctl, and kubectl

Lecture created a bootstrap server and I just used Mac.

• Create a user from AWS console and give IAM policies to run eksctl https://eksctl.io/usage/minimum-iam-policies/

brew install awscli
brew install eksctl
# awscli gave an error from SSL self-signed cert. Declare a env var to bypass
export AWS_CA_BUNDLE=/usr/local/etc/ca-certificates/cert.pem
aws configure # put in access keys
aws eks list-clusters # to verify
eksctl get cluster # to verify

Create a EKS cluster

eksctl create cluster --name jiwon-eks  \
--region ap-southeast-1 \
--node-type t2.small \
--nodes-min 2 \
--nodes-max 3

Once done, delete the cluster to avoid excessive charges. eksctl delete cluster jiwon-eks --region ap-southeast-1

Create a k8s deployment and expose it via LoadBalancer

Use the latest tag on image to fetch the latest image.

kubectl create -f regapp-deployment.yaml
kubectl expose deployment regapp --type=LoadBalancer

Once LB is created, wait a minute and open the tomcat using ELB address. Such as http://a88189294000f4edd95cbad63c5d0bbe-1937471911.ap-southeast-1.elb.amazonaws.com:8080/webapp
