Quick Guide for Datadog Agent on Kubernetes for Infrastructure

  1. Add the Datadog Helm repository.

    helm repo add datadog https://helm.datadoghq.com
helm repo update

  2. Configure datadog-values.yaml.

    For pod-level metrics, add Datadog annotations to enable scraping.

  3. Base configuration

    fullnameOverride: "kfuse-agent"
nameOverride: "kfuse-agent"
datadog:
  apiKey: " "
  #
  # Scenario default: Assumes that Kloudfuse stack & agent both in same VPC and in same K8S cluster
  #
  dd_url: "http://kfuse-ingress-nginx-controller-internal.kfuse/ingester"
  #
  # Scenario 1: Kloudfuse stack & agent both in same VPC, but in different K8S cluster
  #
  # dd_url: "http://<ingress-ip>/ingester"
  #
  # Scenario 2: Kloudfuse stack hosted in a different VPC (hosted at “customer.kloudfuse.io”)
  #
  # dd_url: "https://customer.kloudfuse.io/ingester"
  #
    yaml

  4. Enable orchestrator.

    ...
datadog:
  ...
  orchestratorExplorer:
    enabled: true

clusterAgent:
  datadog_cluster_yaml:
    orchestrator_explorer:
      #
      # Scenario default: Assumes that Kloudfuse stack & agent both in same VPC and in same K8S cluster
      #
      orchestrator_dd_url: "http://kfuse-ingress-nginx-controller-internal.kfuse"
      #
      # Scenario 1: Kloudfuse stack & agent both in same VPC, but in different K8S cluster
      #
      # orchestrator_dd_url: "http://<ingress-ip>"
      #
      # Scenario 2: Kloudfuse stack hosted in a different VPC (hosted at “customer.kloudfuse.io”)
      #
      # orchestrator_dd_url: "https://customer.kloudfuse.io"
      #
agents:
  customAgentConfig:
    ...
    orchestrator_explorer:
      #
      # Scenario default: Assumes that Kloudfuse stack & agent both in same VPC and in same K8S cluster
      #
      orchestrator_dd_url: "http://kfuse-ingress-nginx-controller-internal.kfuse"
      #
      # Scenario 1: Kloudfuse stack & agent both in same VPC, but in different K8S cluster
      #
      # orchestrator_dd_url: "http://<ingress-ip>"
      #
      # Scenario 2: Kloudfuse stack hosted in a different VPC (hosted at “customer.kloudfuse.io”)
      #
      # orchestrator_dd_url: "https://customer.kloudfuse.io"
      #
    yaml

  5. Deploy the agent with the configuration file.

    helm install datadog-agent -f datadog-values.yaml datadog/datadog

  6. Verify that the agent runs in the cluster, and that data flows into Kloudfuse.
