Is it Observable

Episode : The Gateway API

This repository contains the files utilized during the tutorial presented in the dedicated IsItObservable episode related to the Gateway API.

This repository showcase the usage of OpenTelemetry demo with :

• The OpenTelemetry demo
• Dynatrace

We will send all Telemetry data produced by otel-demo to Dynatrace.

Prerequisite

The following tools need to be install on your machine :

• jq
• kubectl
• git
• gcloud ( if you are using GKE)
• Helm

Deployment Steps in GCP

You will first need a Kubernetes cluster with 2 Nodes. You can either deploy on Minikube or K3s or follow the instructions to create GKE cluster:

1.Create a Google Cloud Platform Project

PROJECT_ID="<your-project-id>"
gcloud services enable container.googleapis.com --project ${PROJECT_ID}
gcloud services enable monitoring.googleapis.com \
    cloudtrace.googleapis.com \
    clouddebugger.googleapis.com \
    cloudprofiler.googleapis.com \
    --project ${PROJECT_ID}

2.Create a GKE cluster

ZONE=europe-west3-a
NAME=isitobservable-odigos
gcloud container clusters create "${NAME}" --zone ${ZONE} --machine-type=e2-standard-4 --num-nodes=2

Getting started

Dynatrace Tenant

1. Dynatrace Tenant - start a trial

If you don't have any Dyntrace tenant , then i suggest to create a trial using the following link : Dynatrace Trial Once you have your Tenant save the Dynatrace tenant url in the variable DT_TENANT_URL (for example : https://dedededfrf.live.dynatrace.com)

DT_TENANT_URL=<YOUR TENANT Host>

2. Create the Dynatrace API Tokens

Create a Dynatrace token with the following scope ( left menu Acces Token):

• ingest metrics
• ingest OpenTelemetry traces
• ingest logs

Save the value of the token . We will use it later to store in a k8S secret

DATA_INGEST_TOKEN=<YOUR TOKEN VALUE>

2.Clone the Github Repository

https://github.com/isItObservable/gateway-api
cd gateway-api

3.Deploy most of the components

The application will deploy the entire environemnt:

chmod 777 deployment.sh
./deployment.sh   --dthost "${DT_TENANT_URL}" --dttoken "${DATA_INGEST_TOKEN}"
