Address %q was not found

Error message

Address %q was not found

What it means

After a successful find() call, if it returns nil (address not present in GCE), RenderGCE aborts with 'Address %q was not found'. The forwarding rule cannot be rendered because its IP cannot be resolved; kOps refuses to silently allocate an unspecified IP.

Solutions

1. Create the static Address in GCE (gcloud compute addresses create ...) in the correct region, then re-apply.
2. Correct the address name in the cluster spec to match the existing GCE Address.
3. Provide an explicit IP address in the spec's IPAddress field instead of a name reference.
4. Verify region/project configuration matches where the address was reserved.

Example fix

// before
ipAddress: { name: "old-lb-ip" }
// after
ipAddress: { name: "lb-ip", ipAddress: "34.10.20.30" }

// before applying, assert the address exists and has an IP:
// test -n "$(gcloud compute addresses describe ADDR --region=R --format='value(address)')" || \
//   gcloud compute addresses create ADDR --region=R

When it happens

Trigger: Spec references an Address task with an empty IPAddress, and find() returns nil because no Address with that name exists in the project/region at apply time.

Common situations: Address was deleted from GCE console or by another IaC tool; wrong region configured; address created after this apply was expected to run; name mismatch between spec and GCE.
