waiting for route table create/update completion: %w

Error message

waiting for route table create/update completion: %w

What it means

Wrapped error from future.PollUntilDone after BeginCreateOrUpdate succeeded, meaning the route table create/update operation started but failed or the polling was interrupted (including context cancellation). The resource was not confirmed created/updated.

Solutions

1. Check the wrapped error for the ARM operation failure detail
2. Increase the context timeout for the reconcile operation
3. Avoid concurrent writers to the same route table (e.g., two kOps runs)
4. Verify the route table state in the Azure portal after the failure and re-run reconciliation

Example fix

// before
ctx := context.Background()
// after
ctx, cancel := context.WithTimeout(context.Background(), 5*time.Minute)
defer cancel()

ctx, cancel := context.WithTimeout(ctx, 5*time.Minute)
defer cancel()

var respErr *azcore.ResponseError
if errors.As(err, &respErr) {
	// inspect respErr.ErrorCode / StatusCode for conflict vs transient
}

rt, err := client.CreateOrUpdate(ctx, rg, name, params)
if errors.Is(err, context.DeadlineExceeded) {
	// re-poll or verify current state before retrying the PUT
}

When it happens

Trigger: PollUntilDone(ctx, nil) returns error when the long-running PUT ultimately fails (e.g., conflict, quota, provisioning error), or ctx is cancelled/times out while polling.

Common situations: Slow Azure control plane exceeding the caller's context deadline; concurrent modification conflicts; region outage causing provisioning failure.
