When you delete a cluster it results in the removal of all compute instances and associated resources created for the cluster. Use the following steps to delete a cluster.
- A host cluster.
- Log in to Palette and ensure you are in the correct project scope.
- Navigate to the left Main Menu and click on Clusters.
- Click on the cluster you want to delete.
- Click on the Settings drop-down Menu.
- Click on Delete Cluster.
- Type the cluster name and click on OK.
The cluster status is updated to Deleting while cluster resources are removed. When all resources are successfully deleted, the cluster status is updated to Deleted, and the cluster is removed from the cluster list.
To validate the host cluster is deleted, use the following steps.
- Log in to Palette.
- Navigate to the left Main Menu and click on Cluster.
- Check the box labeled Deleted only to view all the clusters deleted in the last 72 hours.
The cluster you deleted is now listed along with other previously deleted clusters.
If a cluster is stuck in the Deleting state for a minimum of 15 minutes, it becomes eligible for force deletion. You can force delete a cluster from the tenant and project admin scope.
To force delete a cluster, follow the same steps outlined above. After 15 minutes, a Force Delete Cluster option is available in the Settings drop-down Menu. The drop-down menu will provide you with an estimated remaining time left before the force deletion becomes available.
A force delete can result in Palette-provisioned resources being missed in the removal process. Verify there are no remaining resources. Use the following list to help you identify resources to remove.
Failure in removing provisioned resources can result in unexpected costs.
