Challenge 8Install the Threat Stack Container Agent

Install using Helm

Helm is a package manager on top of Kubernetes. It facilitates installation, upgrades, and manages dependencies for the services you install in Kubernetes.

Prerequisites

  • Helm installed
  • Configured Values file

Warning

Use only the command provided to install the Threat Stack Container Agent. Using UDF, establish a Terminal session with the host labelled, “K8S”.

Let’s begin by downloading the values.yaml file used to configure the Helm Chart.

wget https://raw.githubusercontent.com/threatstack/threatstack-helm/master/values.yaml
vim values.yaml
../_images/_Install_K8_DownloadConfigVal.gif

In the values.yaml, lets update a couple things. First, the hostname on line 51 so lab participants can track activity easily in the lab. Next, lets update the agentDeployKey on line 67 with your previously used key.

51 additionalSetupConfig: "--hostname=**$MY_HOSTNAME**"
67 agentDeployKey: "**$MY_DEPLOY_KEY**"

Once you edit the necessary values, then exit by entering the following on vim to write and force quit.

Now that we have our values.yaml file updated, lets deploy the Threat Stack Container Agent using Helm. We start by first adding the repo following a helm install to deploy Threat Stack to the K8 Cluster.

Add the Helm Repo

helm repo add threatstack https://pkg.threatstack.com/helm
../_images/_Install_K8_Deployed.gif

Run Helm Install

helm install threatstack-agent --values values.yaml threatstack/threatstack-agent
