Development

• Simple flask "Hello World" application.

---

EKS

• First, Trying to create kubernetes cluster with this command:

      $ eksctl create cluster \
  			--name capstone \
  			--version 1.17 \
  			--nodegroup-name standard-workers \
  			--node-type t2.micro \
  			--nodes 2 \
  			--nodes-min 1 \
  			--nodes-max 3 \
  			--node-ami auto \
  			--region us-west-2 \
  			--zones us-west-2a \
  			--zones us-west-2b \
  			--zones us-west-2c \
  

• Configure it using this command:

      $ aws eks --region us-west-2 update-kubeconfig --name capstone
