DNS Cleaner

Overview

This command finds and removes DNS entries created by the kyma-gke-long-lasting job in a Google Cloud Platform (GCP) project.

The kyma-gke-long-lasting job creates a GKE cluster to install and test Kyma.

Usage

    --project={gcloud project name} \
    --zone={gcloud zone} \
    --name={resource name} \
    --address={address of the resource}

To turn the dry-run mode off, use:

env GOOGLE_APPLICATION_CREDENTIALS={path to service account file} go run main.go \
    --project={gcloud project name} \
    --zone={gcloud zone} \
    --name={resource name} \
