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"
     #

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"
         #

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.
