Creating firewall.../Created [https://www.googleapis.com/compute/v1/projects/qwiklabs-gcp-286ef104ac93631b/global/firewalls/gclab2].
Creating firewall...done.
NAME    NETWORK  DIRECTION  PRIORITY  ALLOW   DENY
gclab2  default  INGRESS    1000      tcp:80

so the correct command is:

gcloud compute firewall-rules create NAME_OF_YOUR_INSTANCE --allow tcp:80
