scaleway currently only supports clusters in the same zone

Error message

scaleway currently only supports clusters in the same zone

What it means

Hard validation limit in ParseZoneFromClusterSpec: the cluster's subnets span more than one Scaleway zone, which the Scaleway provider does not support — kOps requires every subnet (hence the whole cluster) to live in a single availability zone. The first subnet's zone is taken as the reference; any different subnet zone triggers this.

Solutions

1. Edit the cluster spec so all subnets use the same zone
2. Re-create the cluster with a single-zone network layout
3. Track multi-zone support in the Scaleway provider upstream if needed
