⚠️ Repo Archive Notice

As of Nov 13, 2020, charts in this repo will no longer be updated. For more information, see the Helm Charts Deprecation and Archive Notice, and Update.


Instana is an APM solution built for microservices that enables IT Ops to build applications faster and deliver higher quality services by automating monitoring, tracing and root cause analysis. This solution is optimized for Kubernetes.


This chart is deprecated and no longer supported.


This chart adds the Instana Agent to all schedulable nodes in your cluster via a DaemonSet.


Kubernetes 1.9.x - 1.18.x

Helm 3 prerequisites

Working helm with the stable repo added to your helm client.

Helm 2 prerequisites

Working helm and tiller.

Note: Tiller may need a service account and role binding if RBAC is enabled in your cluster.

Installing the Chart

To configure the installation you can either specify the options on the command line using the –set switch, or you can edit values.yaml.

Required Settings

Configuring the Instana Backend

In order to report the data it collects to the Instana backend for analysis, the Instana agent must know which backend to report to, and which credentials to use to authenticate, known as “agent key”.

As described by the Install Using the Helm Chart documentation, you will find the right values for the following fields inside Instana itself:

  • agent.endpointHost
  • agent.endpointPort
  • agent.key

Note: You can find the options mentioned in the configuration section below

If your agents report into a self-managed Instana unit (also known as “on-prem”), you will also need to configure a “download key”, which allows the agent to fetch its components from the Instana repository. The download key is set via the following value:

  • agent.downloadKey

Zone and Cluster

Instana needs to know how to name your Kubernetes cluster and, optionally, how to group your Instana agents in Custom zones using the following fields:


Either or are required. If you omit, the value of will be used as cluster name as well. If you omit, the host zone will be automatically determined by the availability zone information provided by the supported Cloud providers.

Optional Settings

Configuring Additional Backends

You may want to have your Instana agents report to multiple backends. The first backend must be configured as shown in the Configuring the Instana Backend; every backend after the first, is configured in the agent.additionalBackends list in the values.yaml as follows:

  # Second backend
  - endpointHost: # endpoint host; e.g.,
    endpointPort: 443 # default is 443, so this line could be omitted
    key: ABCDEFG # agent key for this backend
  # Third backend
  - endpointHost: # endpoint host; e.g.,
    endpointPort: 1444 # default is 443, so this line could be omitted
    key: LMNOPQR # agent key for this backend

The snippet above configures the agent to report to two additional backends. The same effect as the above can be accomplished via the command line via:

$ helm install -n instana-agent instana-agent stable/instana-agent ... \
    --set 'agent.additionalBackends[0]' \
    --set 'agent.additionalBackends[0].endpointPort=443' \
    --set 'agent.additionalBackends[0].key=ABCDEFG' \
    --set 'agent.additionalBackends[1]' \
    --set 'agent.additionalBackends[1].endpointPort=1444' \
    --set 'agent.additionalBackends[1].key=LMNOPQR'

Note: There is no hard limitation on the number of backends an Instana agent can report to, although each comes at the cost of a slight increase in CPU and memory consumption.

Configuring a Proxy between the Instana agents and the Instana backend

If your infrastructure uses a proxy, you should ensure that you set values for:

  • agent.pod.proxyHost
  • agent.pod.proxyPort
  • agent.pod.proxyProtocol
  • agent.pod.proxyUser
  • agent.pod.proxyPassword
  • agent.pod.proxyUseDNS

Configuring which Networks the Instana Agent should listen on

If your infrastructure has multiple networks defined, you might need to allow the agent to listen on all addresses (typically with value set to *):

  • agent.listenAddress

Agent Modes

Agent can have either APM or INFRASTRUCTURE. Default is APM and if you want to override that, ensure you set value:

  • agent.mode

For more information on agent modes, refer to the Host Agent Modes documentation.

Installing with Helm 3

First, create a namespace for the instana-agent

$ kubectl create namespace instana-agent

To install the chart with the release name instana-agent and set the values on the command line run:

$ helm install instana-agent --namespace instana-agent \
--set agent.key=INSTANA_AGENT_KEY \
--set agent.endpointHost=HOST \
--set \

Installing with Helm 2

To install the chart with the release name instana-agent and set the values on the command line run:

$ helm install --name instana-agent --namespace instana-agent \
--set agent.key=INSTANA_AGENT_KEY \
--set agent.endpointHost=HOST \
--set \

Uninstalling the Chart

To uninstall/delete the instana-agent release:

Uninstalling with Helm 3

$ helm del instana-agent -n instana-agent

Uninstalling with Helm 2

$ helm del --purge instana-agent

These options will be rarely used outside of development or debugging of the agent.

Parameter Description Default Host path to mount as the agent maven repository nil

Agent Configuration

Besides the settings listed above, there are many more settings that can be applied to the agent via the so-called “Agent Configuration File”, often also referred to as configuration.yaml file. An overview of the settings that can be applied is provided in the Agent Configuration File documentation. To configure the agent, you can either:

  • edit the config map, or
  • provide the configuration via the agent.configuration_yaml parameter in values.yaml

This configuration will be used for all Instana Agents on all nodes. Visit the agent configuration documentation for more details on configuration options.

Note: This Helm Chart does not support configuring Multiple Configuration Files.
