No healthy k8s zone cluster could be selected

[afragop672]

Dear all,

trying to deploy a VKS Supervisor namespace or a VKS cluster to an existing supervisor, deployment fails with an error,

"No healthy k8s zone cluster could be selected"

I checked on Aria Kubernetes Zones, Cloud Account, Supervisor config, and all looks good.

Thnx

Tasos

@afragop672,

This error quite generic and indicates that VMware Aria Automation or Tanzu cannot find a healthy Supervisor Cluster or Kubernetes Zone that meets deployment criteria, often due to readiness or resource issues.

Troubleshooting Steps:

- Check Supervisor Cluster Health in vSphere Client for alarms or control plane issues.

• Verify Node Readiness using `kubectl get nodes`.
• Ensure Resource Availability (CPU, memory, storage) and review vSphere HA settings
• Validate Kubernetes Zone Configuration in Aria Automation, including cloud account links and placement policies.
• Review Events and Logs in vCenter and Aria Automation for specific failure causes.
• Confirm Network Setup (NSX Edge, load balancers) is healthy.

• Re-sync Cloud Account - in Aria Automation if all else looks fine.

If unresolved, share full logs and environment details.
