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: '*'
     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
   

2. 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
