Install TIS Agent

This page describes how to install the TIS Dashboard Agent component. The Agent component is deployed in each individual Istio cluster and is responsible for gathering data from its respective cluster and transmitting it to the Central component. This ensures comprehensive data collection and facilitates real-time monitoring and management across all clusters.

Before you begin

Please ensure you have the following prerequisites:

  1. A Kubernetes cluster with Istio installed and the kubectl configured to communicate with your cluster. TIS Agent is compatible with any Istio distribution including upstream Istio and Tetrate Istio.
  2. helm tool (version 3.6 or later).
  3. Credentials from Tetrate to access Tetrate's private repository. Set your credential as env variable:
    export TIS_USER="<tis-username>"
    export TIS_PASS="<tis-password>"

TIS Agent Installation Steps

  1. Open TIS Dashboard UI

    Open the TIS Dashboard UI and navigate to the Clusters tab. You can find the Clusters tab in the left navigation menu. Since you haven't added any clusters yet, Add cluster button will also be available in Overview page.

    cluster list Cluster list
  2. Add new cluster

    Click on the Add Cluster button to add a new cluster. You will see a form where you can enter the cluster name. After entering the cluster name, click on the Create Cluster button. It will generate a Helm values file that you can use to install the TIS Agent and Helm command to install the TIS Agent.

    Downloading Helm values

    If you did not download the Helm values file and proceed with installing agent, the cluster status will be NOT_CONNECTED. If you want to use same cluster name, you must delete the cluster and add it again to download the Helm values file.

  3. Create image pull secret

    Create a new namespace and an image secret with your credentials. Note that if you have already created the secret, you can skip this step.

    kubectl create namespace tis

    kubectl create secret docker-registry tetrate-tis-creds \
    --docker-server="" \
    --docker-username=${TIS_USER} \
    --docker-password=${TIS_PASS} \
    --docker-email="${USER}@" \
    -n tis

    Customizing Installation

    You can get the list of all available configuration options by running helm show values tis/agent.


    When using TIS Dashboard UI to install the TIS Agent, the Helm version is automatically set to the latest version. If you want to install a specific version, you can set the version in the Helm command.

    Download the Helm values file to a local directory and install the TIS Agent using the command provided in the TIS Dashboard UI.

    helm install tis-agent tis/agent \
    --version 1.0.0 \
    --namespace tis --create-namespace \
