nri-bundle

Groups together the individual charts for the New Relic Kubernetes solution for a more comfortable deployment.

Homepage: https://github.com/newrelic/helm-charts

Bundled charts

This chart does not deploy anything by itself but has many charts as dependencies. This allows you to easily install and upgrade the New Relic Kubernetes Integration using only one chart.

In case you need more information about each component this chart installs, or you are an advanced user that want to install each component separately, here is a list of components that this chart installs and where you can find more information about them:

Component Installed by default? Description
newrelic-infrastructure Yes Sends metrics about nodes, cluster objects (e.g. Deployments, Pods), and the control plane to New Relic.
nri-metadata-injection Yes Enriches New Relic-instrumented applications (APM) with Kubernetes information.
kube-state-metrics Required for newrelic-infrastructure to gather cluster-level metrics.
nri-kube-events Reports Kubernetes events to New Relic.
newrelic-infra-operator (Beta) Used with Fargate or serverless environments to inject newrelic-infrastructure as a sidecar instead of the usual DaemonSet.
newrelic-k8s-metrics-adapter (Beta) Provides a source of data for Horizontal Pod Autoscalers (HPA) based on a NRQL query from New Relic.
newrelic-logging Sends logs for Kubernetes components and workloads running on the cluster to New Relic.
nri-prometheus Sends metrics from applications exposing Prometheus metrics to New Relic.
newrelic-prometheus-configurator Configures instances of Prometheus in Agent mode to send metrics to the New Relic Prometheus endpoint.
newrelic-pixie Connects to the Pixie API and enables the New Relic plugin in Pixie. The plugin allows you to export data from Pixie to New Relic for long-term data retention.
Pixie Is an open source observability tool for Kubernetes applications that uses eBPF to automatically capture telemetry data without the need for manual instrumentation.

Configure components

It is possible to configure settings for the individual charts this chart groups by specifying values for them under a key using the name of the chart, as specified in helm documentation.

For example, by adding the following to the values.yml file:

# Configuration settings for the newrelic-infrastructure chart
newrelic-infrastructure:
  # Any key defined in the values.yml file for the newrelic-infrastructure chart can be configured here:
  # https://github.com/newrelic/nri-kubernetes/blob/main/charts/newrelic-infrastructure/values.yaml

  verboseLog: false

  resources:
    limits:
      memory: 512M

It is possible to override any entry of the newrelic-infrastructure chart, as defined in their values.yml file.

The same approach can be followed to update any of the subcharts.

After making these changes to the values.yml file, or a custom values file, make sure to apply them using:

$ helm upgrade --reuse-values -f values.yaml [RELEASE] newrelic/nri-bundle

Where [RELEASE] is the name of the helm release, e.g. newrelic-bundle.

Monitor on host integrations

If you wish to monitor services running on Kubernetes you can provide integrations configuration under integrations_config that it will passed down to the newrelic-infrastructure chart.

You just need to create a new entry where the "name" is the filename of the configuration file and the data is the content of the integration configuration. The name must end in ".yaml" as this will be the filename generated and the Infrastructure agent only looks for YAML files.

The data part is the actual integration configuration as described in the spec here: https://docs.newrelic.com/docs/integrations/integrations-sdk/file-specifications/integration-configuration-file-specifications-agent-v180

In the following example you can see how to monitor a Redis integration with autodiscovery

newrelic-infrastructure:
  integrations:
    nri-redis-sampleapp:
      discovery:
        command:
          exec: /var/db/newrelic-infra/nri-discovery-kubernetes --tls --port 10250
          match:
            label.app: sampleapp
      integrations:
        - name: nri-redis
          env:
            # using the discovered IP as the hostname address
            HOSTNAME: ${discovery.ip}
            PORT: 6379
          labels:
            env: test

Bring your own KSM

New Relic Kubernetes Integration requires an instance of kube-state-metrics (KSM) to be running in the cluster, which this chart pulls as a dependency. If you are already running or want to run your own KSM instance, you will need to make some small adjustments as described below.

Bring your own KSM

If you already have one KSM instance running, you can point nri-kubernetes to your instance:

kube-state-metrics:
  # Disable bundled KSM.
  enabled: false
newrelic-infrastructure:
  ksm:
    config:
      # Selector for your pre-installed KSM Service. You may need to adjust this to fit your existing installation.
      selector: "app.kubernetes.io/name=kube-state-metrics"
      # Alternatively, you can specify a fixed URL where KSM is available. Doing so will bypass autodiscovery.
      #staticUrl: http://ksm.ksm.svc.cluster.local:8080/metrics

Run KSM alongside a different version

If you need to run a different instance of KSM in your cluster, you can still run a separate instance for the Kubernetes Integration to work as intended:

kube-state-metrics:
  # Enable bundled KSM.
  enabled: true
  prometheusScrape: false
  customLabels:
    # Label unique to this KSM instance.
    newrelic.com/custom-ksm: "true"
newrelic-infrastructure:
  ksm:
    config:
      # Use label above as a selector.
      selector: "newrelic.com/custom-ksm=true"

Values managed globally

Some of the subchart implement the New Relic's common Helm library which means that it honors a wide range of defaults and globals common to most New Relic Helm charts.

Options that can be defined globally include affinity, nodeSelector, tolerations, proxy and others. The full list can be found at user's guide of the common library.

At the time of writing this document, all the charts from nri-bundle except newrelic-logging and synthetics-minion implements this library and honors global options as described below.

Note, the value table below is automatically generated from values.yaml by helm-docs. If you need to add new fields or update existing fields, please update the values.yaml and then run helm-docs to update this value table.

Values

Key Type Default Description
global object See values.yaml change the behaviour globally to all the supported helm charts. See user's guide of the common library for further information.
global.affinity object {} Sets pod/node affinities
