Introduction

This chart creates a daemonset on a Kubernetes cluster using the Helm package manager.

Prerequisites

• Kubernetes 1.10+

Installing the Chart

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

$ helm install --name my-release ckotzbauer/cadvisor

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

Upgrading from v1.x to v2.x

• metrics.relabelings was renamed to metrics.metricsRelabelings to match the ServiceMonitor CRD naming

Uninstalling the Chart

To uninstall/delete the my-release deployment:

$ helm delete my-release

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