About this task

Informer pod memory consumption depends mainly on the number of resources contained in the cluster. Memory limit defines the maximum memory the informer container is allowed to use, while memory request defines how much memory to reserve when scheduling the informer pod. Set the Informer pod's memory request and the Informer pod’s memory limit to at least (number of pods)/8MB, with a default minimum of 200MB. Memory request must not exceed the memory limit. For example:

Estimated pod count 1000 5000 30000
Minimum memory limit 200Mi 625Mi 3.75Gi
Memory request 200Mi 625Mi 3.75Gi

Procedure

  1. Do one of the following:

    • When using a Helm chart, in the Helm install command, add the following command line arguments:

      Shell
      --set memoryLimit=MEM_LIMIT\--set memoryRequest=MEM_REQUEST

      For example:

      Shell
      --set memoryLimit=625Mi\--set memoryRequest=625Mi
    • When using the k8s_informer.yaml, under the line containing “limits:” add the line memory: MEM_LIMIT.

      In the following example, MEM_LIMIT and MEM_REQUEST are 625Mi.

      YAML
        limits:    cpu: 100m    memory: 625Mi  resources:    cpu: 100m    memory: 625Mi

      Note:

      Setting memoryRequest equal to memoryLimit reserves exactly the memory your ACC agent needs. It prevents the ACC agent from being shut down if the system runs low on memory. This guarantees stable, uninterrupted agent operation. If you leave memoryRequest at the default 200Mi while setting a higher memoryLimit (such as 625Mi), the pod is burstable. It schedules against 200Mi but can grow to 625Mi.
