Chrome Remote Desktop Helm Chart

Basic Introduction

This is a Helm chart package to manage Chrome Remote Desktop deployment on your Kubernetes cluster.

Prerequisites

• Persistent storage (optional)
  • Install a persistent storage plugin such as Longhorn (see the steps in the Platform Reference Deployment Guide)

Installation

Using NGC CLI and NGC Web UI

Please see the NGC Helm Charts documentation for general guidance.

Using Helm Dashboard

This Helm chart can be installed on your Kubernetes cluster using the Helm Dashboard UI once the Helm Dashboard Helm Chart is installed.

Using Helm

1. Login to the NGC registry

   helm registry login nvcr.io
   

2. Add repo on your local system

   helm repo add <your-repo-name> https://helm.ngc.nvidia.com/nvidia/holoscan-for-media/ '--username=$oauthtoken' --password=<API-KEY>
   

   where:

   • <your-repo-name> is a short name like holoscan-for-media to be used on your local system to indicate the chart repository on NGC specified by the URL
   • <API-KEY> is your NGC API Key

3. Update the repo or fetch particular chart

   helm repo update
   

   or

   helm pull <your-repo-name>/chrome-remote-desktop
   

   where:

   • <your-repo-name> is the short name you used in the helm repo add command above

4. Now you can see all the charts available

   helm search repo
   

5. You are ready to install Chrome Remote Desktop using its Helm chart

   Creating a persistent volume claim is optional, but ensures remote access still works after the pod is restarted.

   Create a YAML file, <pv-claim>.yaml, like this:

   apiVersion: v1
   kind: PersistentVolumeClaim
   metadata:
     name: <pv-claim>
     namespace: default
   spec:
     accessModes:
     - ReadWriteOnce
     resources:
       requests:
         storage: 2Mi
     storageClassName: longhorn
   

   where:

   • <pv-claim> is a unique name on your local system, like alice-chrome-remote-desktop-pv-claim
   • the requested storage can be increased as needed; the value is given in bytes, using suffixes like k, M, G (or the power-of-two equivalents like Ki, Mi, Gi), so 2Mi is a little more than 2M, or 2 Megabytes, enough for a few cat pictures

   Create the PVC with the following command

   kubectl create -f <pv-claim>.yaml
   

   Install using below command

   helm install --set env.CODE=<one-time-code>,persistentVolumeClaim=<pv-claim> <release-name> <your-repo-name>/chrome-remote-desktop
   

   where:

   • <one-time-code> is created as described below
   • <pv-claim> is the short name you used in creating the persistent volume claim above
   • <release-name> is a short name, like alice-chrome-remote-desktop, which should be unique on your local system, to indicate this particular installation of this application
   • <your-repo-name> is the short name you used in the helm repo add command above

   In order to get a one-time code, go to https://remotedesktop.google.com/headless and follow the steps to set up another computer. A one-time code is shown by the web page as part of a full command line like:

   DISPLAY= /opt/google/chrome-remote-desktop/start-host --code="4/0AQlEd8xOqZqReqM1FnZRwdZKB3QrQudI7aPVNkX6ZBDqHH1JUMP5f8T-e-gzH9p1o1oTzw" --redirect-url="https://remotedesktop.google.com/_/oauthredirect" --name=$(hostname)
   

6. After installation you can check the status

   kubectl get all -o wide
   

7. Once the pod is running you can use the Chrome Remote Desktop

   Access it via https://remotedesktop.google.com/access.

8. Other commands to manage the installed application

   helm status <release-name>
   helm get all <release-name>
   helm uninstall <release-name>
   

   where:

   • <release-name> is the short name you used in the helm install command above
