Prerequisites

Stack Serverless Observability

Before setting up observability for Kubernetes, make sure you have the following:

• Elastic Stack (self-managed or Elastic Cloud) version 8.16.0 or higher, or an Elasticsearch Serverless project.

• A Kubernetes version supported by the OpenTelemetry Operator. Refer to the operator's compatibility matrix for more details.

• If you opt for automatic certificate generation and renewal on the OpenTelemetry Operator, install cert-manager in the Kubernetes cluster. By default, the operator uses a self-signed certificate and doesn't require cert-manager.

The minimum supported version of the Elastic Stack for OpenTelemetry-based monitoring on Kubernetes is 8.16.0. Different Elastic Stack releases support specific versions of the kube-stack Helm chart.

You can download the values file for a specific Elastic Stack version from the following URL:

https://raw.githubusercontent.com/elastic/elastic-agent/refs/tags/v<STACK_VERSION>/deploy/helm/edot-collector/kube-stack/values.yaml
		

Where <STACK_VERSION> is the version of the Elastic Stack you are using, for example 9.1.2.

For Serverless, use the latest version of the values file. For version 8.16.0, use this chart.
