Edge Delta on Kubernetes

Overview

The setup process for deploying Edge Delta within a Kubernetes cluster natively leverages the Kubernetes APIs and other components to provide a seamless onboarding, and automated monitoring experience.

Many of the commonly used Kubernetes Services are supported by Edge Delta:

• Amazon EKS
• Azure AKS
• Google GKE
• OpenShift Enterprise Kubernetes
• Bare Metal Kubernetes

If you are new to Kubernetes, please refer to documentation for a few tools to create your first cluster:

• Docker
• Kubeadm
• AWS & Kops
• AWS EKS
• GCP GKE
• Azure AKS

Kubernetes Requirements

The Edge Delta pipeline uses eBPF to collect network metrics. Therefore, the following Kubernetes environment configuration is required for Kubernetes network metrics and eBPF to work:

• Linux kernel version 5.8 or later.
• Linux kernel built with the CONFIG_DEBUG_INFO_BTF=y and CONFIG_DEBUG_INFO_BTF_MODULES=y flags.

To check for the flag:

docker run -it --rm --privileged --pid=host ubuntu nsenter -t 1 -m -u -n -i sh -c 'cat /proc/config.gz | gunzip | grep CONFIG_DEBUG_INFO_BTF'

The output should show CONFIG_DEBUG_INFO_BTF=y and CONFIG_DEBUG_INFO_BTF_MODULES=y.

In the case of minikube, the agent can run on minikube with the Docker driver. Docker must be at least v26.0.0 (Docker Desktop v4.29.0) and it is started as follows:

minikube start --driver docker

Kubernetes Deployment Methods

There are a number of different ways to deploy an Edge Delta pipeline in a Kubernetes environment: using Helm, via Terraform, or you can automate deployments with a tool such as ArgoCD.

Note: The kubectl installation method is no longer supported. Please use Helm.
