add query expressions management by prom-adapter-config

[saikey0379]

What type of PR is this?

• Add support for automatic rendering of query expressions
• More user-friendly query expressions management capabilities
• Add support for extension-labels

Examples

Make sure you include metrics in your prometheus-adapter-config file

externalRules:
- seriesQuery: 'connection_count'
  metricsQuery: 'sum(<<.Series>>{<<.LabelMatchers>>})'
  resources:
    namespaced: false
  name:
    matches: "^(.*)_count"
    as: "${1}_per_second"

Add args

    command:
    - /craned
    args:
    ...
    - --prometheus-adapter-configmap=crane-system/prometheus-adapter-config/config.yaml
    #- --prometheus-adapter-config=/etc/adapter/config.yaml

Modify ehpa config

Delete annotation for metric-query "metric-query.autoscaling.crane.io: xxx"

Add metric config

  metrics:
  - external:
      metric:
        name: connection_per_second
        selector:
          matchLabels:
            pod_namespace: "default"
            pod_project: "test"
      target:
        averageValue: "30"
        type: AverageValue
    type: External

Test

# kubectl get tsp test -o yaml | grep expression
    expressionQuery:
      expression: sum(connection_count{pod_namespace="default",pod_project="test"})

Extension-labels

Add annotation for extension-labels

apiVersion: autoscaling.crane.io/v1alpha1
kind: EffectiveHorizontalPodAutoscaler
metadata:
  name: test
  namespace: default
  annotations:
    prom-adapter.autoscaling.crane.io/extension-labels: |
      [{"cluster":"prod"}]

Test

# kubectl get tsp test -o yaml | grep expression
    expressionQuery:
      expression: sum(connection_count{cluster="prod",pod_namespace="default",pod_project="test"})
