Cleanup


Remove the Bookinfo application and clean it up (delete the routing rules and terminate the application pods):

# Clean everything - remove Bookinfo application and all Istio VirtualServices, Gateways, DestinationRules
sed -i "/read -r NAMESPACE/d" samples/bookinfo/platform/kube/cleanup.sh
samples/bookinfo/platform/kube/cleanup.sh

Output:

Clean AWS:

# aws route53 delete-hosted-zone --id $(aws route53 list-hosted-zones --query "HostedZones[?Name==\`${MY_DOMAIN}.\`].Id" --output text)
aws iam detach-user-policy --user-name "${USER}-eks-cert-manager-route53" --policy-arn $(aws iam list-policies --query "Policies[?PolicyName==\`${USER}-AmazonRoute53Domains-cert-manager\`].{ARN:Arn}" --output text)
aws iam delete-policy --policy-arn $(aws iam list-policies --query "Policies[?PolicyName==\`${USER}-AmazonRoute53Domains-cert-manager\`].{ARN:Arn}" --output text)
aws iam delete-access-key --user-name ${USER}-eks-cert-manager-route53 --access-key-id $(aws iam list-access-keys --user-name ${USER}-eks-cert-manager-route53 --query "AccessKeyMetadata[].AccessKeyId" --output text)
aws iam delete-user --user-name ${USER}-eks-cert-manager-route53

eksctl delete cluster --name=${USER}-k8s-istio-webinar --wait
