Uninstallation Guide - AWS (4.2)

These uninstallation steps must be performed in sequence to ensure that all resources are being removed systematically.

Usage Engine Private Edition

Wait a few minutes for the External-DNS to cleanup Route53 hosted zone records. All records will be deleted except SOA, NS, and CNAME records.

Hint!

To monitor the hosted zone records cleanup, refresh the Route53 dashboard, Hosted zones | Records section.

Wait for few minutes for the AWS Load Balancer Controller to cleanup EC2 load balancers.

Hint!

To monitor the EC2 load balancers cleanup, refresh the EC2 dashboard, EC2 | Load balancers section.

Proceed to the next step once route53 hosted zone records and EC2 load balancers are cleared.
