Health check

============

List health checks::
|
|
|
18 |
|
|
|
19 |
gcloud compute health-checks list --format=yaml
|
|
|

|
|
|

In order for LB to function you need to define health checks. They run outside of intranet so
|
|
|
22 |
firewall rules have to be applied to VMs for checks to succeed::
|
|
|
23 |
|
|
|
24 |
gcloud compute firewall-rules create fw-allow-health-check \
|
|
|
25 |
--network=default \
|
|
|
26 |
--action=allow \
|
|
|
27 |
--direction=ingress \
|
|
|
28 |
--source-ranges=130.211.0.0/22,35.191.0.0/16 \
|
|
|

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