digitalocean cloud provider currently supports one region on

Error message

digitalocean cloud provider currently supports one region only.

What it means

setupZones (DigitalOcean branch) validation: fires when more than one zone is given. DigitalOcean zones are regions and the provider supports only a single region per cluster, so multi-zone input is rejected before subnet mapping.

Solutions

1. Pass a single --zones value (one DO region) for DigitalOcean clusters
2. Split multi-region deployments into separate clusters
