How to override detected total memory

overrideDetectedTotalMemory

The spec.<group>.overrideDetectedTotalMemory flag is an option that allows users to override the total memory available to the ArangoDB member by automatically injecting ARANGODB_OVERRIDE_DETECTED_TOTAL_MEMORY ENV variable into the container with the value of spec.<group>.resources.limits.memory.

Sample:

apiVersion: database.arangodb.com/v1
kind: ArangoDeployment
metadata:
  name: cluster
spec:
  mode: Cluster
  dbservers:
    overrideDetectedTotalMemory: true
    resources:
      limits:
        memory: 1Gi
