Kepler DaemonSet Customization

Kepler enables a function to hybrid read environment variable from attributes directly (container.env) and from the ConfigMap. Note that, all steps will be operated by Kepler Operator if the operator is installed.

To set environments by ConfigMap:

1. Create/Generate ConfigMap

apiVersion: v1
kind: ConfigMap
metadata:
  name: kepler-cfm
  namespace: kepler-system
data:
  MODEL_SERVER_ENABLE: true
  COUNTER_METRICS: '*'
  CGROUP_METRICS: '*'
  BPF_METRICS: '*'
  # KUBELET_METRICS: ''
  # GPU_METRICS: ''
  PERF_METRICS: '*'
  MODEL_CONFIG: |
    POD_COMPONENT_ESTIMATOR=true
    POD_COMPONENT_INIT_URL=https://raw.githubusercontent.com/sustainable-computing-io/kepler-model-server/main/tests/test_models/DynComponentPower/CgroupOnly/ScikitMixed.zip

1. Mount the ConfigMap to DaemonSet:

  spec:
    containers:
      - name: kepler-exporter
        volumeMounts:
        - name: cfm
          mountPath: /etc/config
          readOnly: true
      volumes:
      - name: cfm
        configMap:
          name: kepler-cfm
