NSX Tier-0 Gateway and Edge Cluster resources are not removed when VKS vSphere Namespace is deleted

Products

• VMware vSphere Kubernetes Service

Issue/Introduction

Deleting a vSphere namespace does not delete its associated NSX Tier-0 gateway or edge cluster resources 

Environment

• VMware vSphere Kubernetes Service (VKS)
• VMware NSX

Cause

• This is expected behavior when vSphere namespace deletion takes place 
• NSX Tier-0 gateway and edge cluster resources are manually created and managed by the administrator and they are not dynamically provisioned by the supervisor control plane 
• During a namespace deletion event, the VKS process to clean up is purposefully limited to the logical routing components it created such as the Tier-1 Gateway or specific load balancers 

Resolution

Manually remove the NSX Tier-0 gateway and edge cluster resources if they are no longer being used
