if len(hostParts) > 1 {

This should be >= so short host names also work.

As playground currently does not work here the example code.

package main

func getShortname(hostname string) (string, error) {
	if len(hostname) == 0 {
		return "", fmt.Errorf("unable to find shortname from %s as len is 0 %d", hostname, len(hostname))
	}
	hostParts := strings.Split(hostname, ".")
	if len(hostParts) >= 1 {
		return hostParts[0], nil
	}
	return "", fmt.Errorf("unable to find shortname from %s, as hostParts are %v", hostname, hostParts)
}

func main() {
	fmt.Println(getShortname("wuerfelchen-w-1"))
}
