If you're redeploying an elastic runtime environment, run the cluster uninstaller to
clean up AWS and Kubernetes resources.
Run the cluster uninstaller only
after you have run the cluster installer. If you haven't run the cluster installer,
the uninstaller fails.
Before you run the uninstaller, verify that there are no jobs running on the
elastic runtime environment. Running the uninstaller is irreversible and
terminates any running jobs.
To run the uninstaller, run the following command on the master node:
./cluster_uninstall.sh
The cluster uninstaller deletes
resources including Auto Scaling groups, EC2 instances, launch templates, and secrets.
