    13 ============

    14 

    15 List health checks::

    16 

    17   gcloud compute health-checks list --format=yaml

    18 

    19 In order for LB to function you need to define health checks. They run outside of intranet so

    20 firewall rules have to be applied to VMs for checks to succeed::

    21 

    22   gcloud compute firewall-rules create fw-allow-health-check \

    23     --network=default \

    24     --action=allow \

    25     --direction=ingress \

    26     --source-ranges=130.211.0.0/22,35.191.0.0/16 \

    27     --target-tags=allow-health-check \

    28     --rules=tcp:80
