Scaleway — NodePool, NodeClass & Workload

Full manifests and kubectl commands for Scaleway.

Replace placeholders
  • <HOST_TAILSCALE_IP> → Kind control-plane Tailscale IP
  • your-scaleway-project-id → Scaleway project ID

Ensure secrets exist: tailscale-auth, scaleway-credentials.

Flow: NodePool, NodeClass, Workload → Pod Pending → CloudBroker → Provision VM → Node Ready → Pod Scheduled
Scaleway provisioning flow: apply manifests → pod pending → CloudBroker recommends → controller provisions VM → node joins → pod schedules.

1. Create secrets

# Tailscale auth key (required by NodeClass)
kubectl create secret generic tailscale-auth --from-literal=authkey="<YOUR_TAILSCALE_AUTHKEY>" -n default

# Scaleway credentials (SCW_SECRET_KEY required; SCW_ACCESS_KEY recommended)
kubectl create secret generic scaleway-credentials \
  --from-literal=SCW_SECRET_KEY="<YOUR_SCW_SECRET_KEY>" \
  --from-literal=SCW_ACCESS_KEY="<YOUR_SCW_ACCESS_KEY>" \
  -n default

5. Apply and verify

# Save the manifests above to scaleway-example.yaml, then:
kubectl apply -f scaleway-example.yaml

# Watch NodeClaim creation
kubectl get nodeclaims -w

# Once node is Ready, verify pod
kubectl get pods -o wide
kubectl get nodes -l cloudburst.io/provider=scaleway
