Install Kubernetes on a hybrid cluster with Windows and Linux nodes

Define your subcharts

Create a Yaml file that defines your values. This file defines the different subcharts that Helm will install and then assigns values to them.

An example of a yaml file that you could name values.yaml is this:

global:
  licenseKey: mykey
  cluster: mycluster
  lowDataMode: true

newrelic-infrastructure:
  enabled: true
  nodeSelector:
    kubernetes.io/os: linux

kube-state-metrics:
  enabled: true
  image:
    tag: v2.10.0
  nodeSelector:
    kubernetes.io/os: linux

nri-kube-events:
  enabled: true
  nodeSelector:
    kubernetes.io/os: linux

newrelic-logging:
  enabled: true
  enableWindows: true

nri-metadata-injection:
  enabled: true
  nodeSelector:
    kubernetes.io/os: linux

newrelic-prometheus-agent:
  enabled: true
  verboseLog: true
  config:
    kubernetes:
      integrations_filter:
        enabled: false
  nodeSelector:
    kubernetes.io/os: linux

Here are some important things to keep in mind:

• Other subcharts may exist in nri-bundle that are not represented in this file. If you'd like to add those subcharts, then add their key or value pairs to your yaml file.
• The newrelic/nri-bundle chart contains the latest updates for Linux-based nodes.
• You can also configure the newrelic-logging chart during this step to install to both Linux and Windows nodes.
• You must configure a NodeSelector to avoid scheduling to Windows. If an installation fails on a mixed cluster using default values from guided install, add the nodeSelector values.

Install newrelic-bundle

Run this command to install the newrelic-bundle:

$
helm upgrade --install newrelic-bundle newrelic/nri-bundle --namespace newrelic -f values-newrelic.yaml

All pods should start when Helm starts, including a logging pod on each Windows node.

Define newrelic-infrastructure for Windows nodes

Create a second yaml file to add values for the newrelic-infrastructure v2 chart. This is a separate yaml file from the one you created in step one. This is an example yaml file for newrelic-infrastructure that you could name windows-values.yaml:

global:
  licenseKey: mykey
  cluster: mycluster

  enableLinux: false
  enableWindows: true
  windowsOsList:
    - version: 2022
      imageTag: 2-windows-ltsc2022-alpha
      buildNumber: 10.0.20348
  windowsNodeSelector:
    kubernetes.io/os: windows

The example adds values for a Windows 2022 Node Group or Node Pool.

If you're running a different Windows Node Group or Node pool version, then adjust the windowsOsList section with the appropriate values. You can view these values in our Windows install section.

Install newrelic-infrastructure chart

Run this command to install v2.7.2 version of the newrelic-infrastructure chart:

$
helm upgrade --install newrelic-windows newrelic/newrelic-infrastructure \
>
  --namespace newrelic --version 2.7.2 -f windows-values.yaml

When Helm returns, you should see newrelic-windows-newrelic-infrastructure pods on each Windows node.

View your data

Once you generate some data, you can view it in New Relic. Go to one.newrelic.com > All capabilities > Kubernetes, then select your cluster.
