➕ OpenTelemetry Demo with Elastic Observability

The following guide describes how to setup the OpenTelemetry demo with Elastic Observability using Docker compose or Kubernetes.

Docker compose

1. Start a free trial on Elastic Cloud and copy the endpoint and secretToken from the Elastic APM setup instructions in your Kibana.
2. Open the file src/otelcollector/otelcol-config-extras.yml in an editor and replace the following two placeholders:
   • YOUR_APM_ENDPOINT_WITHOUT_HTTPS_PREFIX: your Elastic APM endpoint (without https:// prefix) that must also include the port (example: 1234567.apm.us-west2.gcp.elastic-cloud.com:443).
   • YOUR_APM_SECRET_TOKEN: your Elastic APM secret token.
3. Start the demo with the following command from the repository's root directory:

   docker-compose up -d
   

Kubernetes

Prerequisites:

• Create a Kubernetes cluster. There are no specific requirements, so you can create a local one, or use a managed Kubernetes cluster, such as GKE, EKS, or AKS.
• Set up kubectl.
• Set up Helm.

Start the Demo

1. Setup Elastic Observability on Elastic Cloud.
2. Create a secret in Kubernetes with the following command.

   kubectl create secret generic elastic-secret \
     --from-literal=elastic_apm_endpoint='YOUR_APM_ENDPOINT_WITHOUT_HTTPS_PREFIX' \
     --from-literal=elastic_apm_secret_token='YOUR_APM_SECRET_TOKEN'
   

   Don't forget to replace
   • YOUR_APM_ENDPOINT_WITHOUT_HTTPS_PREFIX: your Elastic APM endpoint (without https:// prefix) that must also include the port (example: 1234567.apm.us-west2.gcp.elastic-cloud.com:443).
   • YOUR_APM_SECRET_TOKEN: your Elastic APM secret token
3. Execute the following commands to deploy the OpenTelemetry demo to your Kubernetes cluster:

   # switch to the kubernetes/elastic-helm directory
   cd kubernetes/elastic-helm
   
   # add the open-telemetry Helm repostiroy
   helm repo add open-telemetry https://open-telemetry.github.io/opentelemetry-helm-charts
   
   # deploy the demo through helm install
   helm install -f values.yaml my-otel-demo open-telemetry/opentelemetry-demo
