Installation

Kubernetes

Detailed information about agent and extension installation in kubernetes can also be found in our documentation.

Recommended (via agent helm chart)

All extensions provide a helm chart that is also integrated in the helm-chart of the agent.

You must provide additional values to activate this extension.

--set extension-datadog.enabled=true \
--set extension-datadog.datadog.apiKey="{{API_KEY}}" \
--set extension-datadog.datadog.applicationKey="{{APPLICATION_KEY}}" \
--set extension-datadog.datadog.siteParameter="{{SITE_PARAMETER}}" \

Additional configuration options can be found in the helm-chart of the extension.

If you need more control, you can install the extension via its dedicated helm-chart.

helm repo add steadybit-extension-datadog https://steadybit.github.io/extension-datadog

Linux Package

Please use our agent-linux.sh script to install the extension on your Linux machine. The script will download the latest version of the extension and install it using the package manager.

After installing, configure the extension by editing /etc/steadybit/extension-datadog and then restart the service.

Extension registration

Make sure that the extension is registered with the agent. In most cases this is done automatically. Please refer to the documentation for more information about extension registration and how to verify.

Proxy

To communicate to Datadog via a proxy, we need the environment variable https_proxy to be set. This can be set via helm using the extraEnv variable

--set "extraEnv[0].name=HTTPS_PROXY" \
--set "extraEnv[0].value=https:\\user:pwd@CompanyProxy.com:8888"
