gke/ERR/2021_013

Product: Google Kubernetes Engine
Rule class: ERR - Something that is very likely to be wrong

Description

GKE automatically creates firewall rules for cluster communication. We verify that the VPC firewall rules are present.

Remediation

If the firewall rules are not present, it could be because of one of the following reasons:

• The firewall rules couldn’t be created (for example in a shared VPC scenario)
• The firewall rules were disabled or deleted

Further information

• Automatically created firewall rules
• Providing the GKE Ingress controller permission to manage host project firewall rules
