Apache SWCK Adapter Helm Chart

Apache SWCK Adapter is a component that provides custom metrics coming from SkyWalking OAP cluster for autoscaling by Kubernetes HPA.

Introduction

This chart bootstraps a SWCK Adapter deployment on a Kubernetes cluster using the Helm package manager.

Prerequisites

  • Kubernetes 1.24.0+
  • Helm 3

Installing the Chart

To install the chart with the release name my-release:

$ helm install my-release adapter -n <namespace>

The command deploys the adapter on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.

Tip: List all releases using helm list

Uninstalling the Chart

To uninstall/delete the my-release deployment:

$ helm uninstall my-release -n <namespace>

The command removes all the adapter components associated with the chart and deletes the release.

The following table lists the configurable parameters of the adapter chart and their default values.

.namespace Namespace of adapter deployment skywalking-custom-metrics-system
.replicas The replicas of adapter 1
.serviceAccountName The service account name of adapter skywalking-custom-metrics-apiserver
