# OpenTelemetry Demo with Google Cloud This repository contains deployment configuration and instructions for deploying the upstream [OpenTelemetry Demo](https://github.com/open-telemetry/opentelemetry-demo) configured to work with Google Cloud Observability products (Cloud Monitoring, Cloud Logging, and Cloud Trace). **This is not an officially supported Google product.** ## Repository Overview This repository does not contain the source code for the microservices. It is used to deploy the OpenTelemetry Astronomy Shop (using upstream images) and configure GCP integrations. - For general information about the upstream demo, see the [upstream repository](https://github.com/open-telemetry/opentelemetry-demo). - For guidelines on how to contribute or develop in this repo, see [CONTRIBUTING.md](CONTRIBUTING.md) and [agents.md](agents.md). - To register the deployed demo with GCP App Hub, see the [App Hub Skill](.agents/skills/register-apphub/SKILL.md). ## Running on GKE The recommended way to run the demo on GKE is with the official Helm chart via Helmfile. ### GKE Managed OpenTelemetry Prerequisites You must enable Managed OpenTelemetry on your GKE cluster. For a new GKE Autopilot cluster: ```console gcloud beta container clusters create-auto CLUSTER_NAME \ --project=PROJECT_ID \ --managed-otel-scope=COLLECTION_AND_INSTRUMENTATION_COMPONENTS \ --location=LOCATION ``` For a new GKE Standard cluster: ```console gcloud beta container clusters create CLUSTER_NAME \ --project=PROJECT_ID \ --managed-otel-scope=COLLECTION_AND_INSTRUMENTATION_COMPONENTS \ --location=LOCATION ``` Or update an existing cluster: ```console gcloud beta container clusters update CLUSTER_NAME \ --project=PROJECT_ID \ --managed-otel-scope=COLLECTION_AND_INSTRUMENTATION_COMPONENTS \ --location=LOCATION ``` Replace `CLUSTER_NAME`, `PROJECT_ID`, and `LOCATION` with your cluster's details. Note: The cluster version must be `1.34.1-gke.2178000` or later. ### Deploying with Helmfile Make sure you have the following installed: - [Helmfile](https://helmfile.readthedocs.io/en/stable/#installation) - [Helm](https://helm.sh/docs/intro/install/) - [helm-diff plugin](https://github.com/databus23/helm-diff) Ensure you have either configured or disabled Workload Identity in your cluster. ```console helmfile --interactive apply -f gcp/helmfile.yaml ``` #### Cleaning up To clean up, run: ```console helmfile --interactive destroy -f gcp/helmfile.yaml ``` ### (Alternative) Using `kubectl apply` Installing with the Helm chart is recommended, but you can also use `kubectl apply` to install the manifests directly. First, make sure you have followed the Workload Identity setup steps above. Install the manifests: ```console kubectl apply -n otel-demo -f ./kubernetes/opentelemetry-demo.yaml ``` ## Seeing Telemetry With the demo running, you should see telemetry automatically created by the demo's load generator. You can see metrics under "Prometheus Target" in Cloud Monitoring: ![metrics](gcp_metrics.png) Traces in the Trace explorer: ![traces](gcp_traces.png) And logs in the Logs explorer organized by service: ![logs](gcp_logs.png)
