export KOPS_STATE_STORE=s3://<aws_bucket_name>export AWS_ACCESS_KEY_ID=$(aws configure get aws_access_key_id)export AWS_SECRET_ACCESS_KEY=$(aws configure get aws_secret_access_key)
Example: kops create cluster --node-count 2 --node-size t3a.medium --master-size t3a.medium --zones us-east-1b,us-east-1c --networking cilium --cloud-labels "Team=myTeam,Owner=myName,env=T3sTing" er1ck.k8s.local
