When you have previously registered an existing EKS cluster in Cocktail and need to delete it, simply delete the cluster from the AWS console. Please keep this in mind.
1) Register the created EKS cluster with the Cocktail Cloud using the following procedure.
1) Click on the "+ Register cluster in use" button in the upper right corner of the [Infrastructure] - [Clusters] tab.
1) Select 'Amazon Web Service' as the provider in the cluster configuration form.
2) Choose the type attribute as 'EKS'.
3) Once these two attributes are selected, the Cluster ID setting will be displayed in the cluster configuration form.
4) Choose the region as the one where EKS was created (Example: Seoul (ap-northeast-2)).
The Provider and Type fields are mandatory.
1) Click the "Save" button in the menu bar to save the cluster registration.
2) After registration is complete, the cluster list will be displayed.
1) To use PV/PVC, you need to create a new storage class.
1) Click on the "+ Create" button at the top right corner of the [Storage] - [Storage Classes] tab, then select AWS EBS CSI.
1) Fill out the settings form accordingly, then click the "Save" button.
1) You can now verify the created storage class
