failed to convert droplet ID to int: %s

Error message

failed to convert droplet ID to int: %s

What it means

deleteDroplet parses the resource tracker's t.ID string as an integer droplet ID via strconv.Atoi; failure is wrapped here. DO droplet IDs are numeric, so a non-numeric ID means the tracker was built with wrong data.

Solutions

1. Inspect the Resource ID in the source state; it must be the numeric DO droplet ID
2. Re-fetch state from the cluster spec rather than hand-edited manifests
3. Report/fix the code path that set a non-numeric ID
4. Delete the droplet manually via doctl compute droplet delete <id> if kOps state is unrecoverable

Example fix

// before
t.ID = "web-1"  // slug, not numeric
// after
t.ID = "31644451"  // numeric DO droplet ID

if n, err := strconv.Atoi(t.ID); err != nil || n <= 0 {
	return fmt.Errorf("droplet ID %q is not a valid numeric DO droplet ID", t.ID)
}

func isNumericID(id string) bool {
	_, err := strconv.Atoi(id)
	return err == nil
}

dropletID, err := strconv.Atoi(t.ID)
if err != nil {
	return fmt.Errorf("failed to convert droplet ID to int: %w", err)
}

When it happens

Trigger: t.ID is not a valid base-10 integer, e.g. empty string, a resource whose ID field was populated with a name/slug instead of a DO numeric ID.

Common situations: Corrupted or hand-edited cluster state/manifest; a bug populating Resource.ID for droplets; running kops against state referencing non-DO resources.
