This page describes how to install the Cluster Agent. For optional post-installation steps, including instrumenting applications with App Server Agents, see Post-Install Workflow.

Installation Overview

You can install the Cluster Agent using either the Kubernetes CLI (kubectl) or Helm. In both cases, the Cluster Agent Operator is installed first, followed by the Cluster Agent. The exact configuration applied during the installation differs slightly based on whether the cluster is an OpenShift or Kubernetes cluster.

Installation Workflow

You must make these decisions during the installation workflow: 

The Cluster Agent requires that you install the Metrics Server in the cluster. If the metrics server is not already installed under the kube-system namespace, then you can install it using the Kubernetes CLI, as described in Install the Cluster Agent with the Kubernetes CLI. If you are using the Cluster Agent Helm chart, you can set the install.metrics-server Helm value to true to install the Metrics Server subchart. See Install the Cluster Agent with Helm Charts.

After the installation completes, see Validate the Cluster Agent Installation for validation and troubleshooting procedures.

Post-Install Workflow

After you install and Validate the Cluster Agent, you can instrument the Kubernetes applications in the cluster with AppDynamics Server Agents. See Container Installation Options for an overview of the options.

To install the AppDynamics Server Visibility Agent or Network Agent on cluster nodes, see Install Infrastructure Visibility with the Cluster Agent Operator.

To enable log collection for failing pods on on-premises Controllers, see Enable Log Collection for Failing Pods.
