asm/ERR/2024_002

Sufficient resources (CPU and memory) then Istiod pods are scheduled.

Product: Anthos Service Mesh
Rule class: ERR - Something that is very likely to be wrong

Description

When provisioning ASM, make sure that the istiod ods have sufficient resources so that they can be scheduled properly.

Insufficient memory or CPU resources can prevent Istiod pods from being scheduled, potentially leading to control plane malfunctions and disruptions in Anthos Service Mesh (ASM) functionality.

Remediation

If the Istiod pods are not getting enough resources, you may need to increase their resource requests in the Istio configuration. Also, ensure that your GKE nodes have enough allocatable CPU and memory resources to accommodate the increased requests for Istiod pods.

Further information

Further, checking the Istiod logs will likely give more info.
