Deploying the OpenTelemetry Demo

1. Create a namespace

To not conflict with other workshops, we will deploy the OpenTelemetry Demo in a separate namespace called otel-demo. To create the namespace, run the following command:

kubectl create namespace otel-demo

2. Deploy the OpenTelemetry Demo

Next, change to the directory containing the OpenTelemetry Demo application:

cd ~/workshop/apm

Deploy the OpenTelemetry Demo application:

kubectl apply -n otel-demo -f otel-demo.yaml

serviceaccount/opentelemetry-demo created
service/opentelemetry-demo-adservice created
service/opentelemetry-demo-cartservice created
service/opentelemetry-demo-checkoutservice created
service/opentelemetry-demo-currencyservice created
service/opentelemetry-demo-emailservice created
service/opentelemetry-demo-featureflagservice created
service/opentelemetry-demo-ffspostgres created
service/opentelemetry-demo-frontend created
service/opentelemetry-demo-kafka created
service/opentelemetry-demo-loadgenerator created
service/opentelemetry-demo-paymentservice created
service/opentelemetry-demo-productcatalogservice created
service/opentelemetry-demo-quoteservice created
service/opentelemetry-demo-recommendationservice created
service/opentelemetry-demo-redis created

deployment.apps/opentelemetry-demo-adservice created
deployment.apps/opentelemetry-demo-cartservice created
deployment.apps/opentelemetry-demo-checkoutservice created
deployment.apps/opentelemetry-demo-currencyservice created
deployment.apps/opentelemetry-demo-emailservice created
deployment.apps/opentelemetry-demo-featureflagservice created
deployment.apps/opentelemetry-demo-ffspostgres created
deployment.apps/opentelemetry-demo-frauddetectionservice created
deployment.apps/opentelemetry-demo-frontend created
deployment.apps/opentelemetry-demo-kafka created
deployment.apps/opentelemetry-demo-loadgenerator created
deployment.apps/opentelemetry-demo-paymentservice created
deployment.apps/opentelemetry-demo-productcatalogservice created
deployment.apps/opentelemetry-demo-quoteservice created
deployment.apps/opentelemetry-demo-recommendationservice created
deployment.apps/opentelemetry-demo-redis created
deployment.apps/opentelemetry-demo-shippingservice created

Once the application is deployed, we need to wait for the pods to be in a Running state. To check the status of the pods, run the following command:

kubectl get pods -n otel-demo

3. Validate the application is running

To validate the application is running, we will port-forward the frontend service. To do this, run the following command:

kubectl port-forward svc/opentelemetry-demo-frontend 8083:8080 -n otel-demo --address='0.0.0.0'

Obtain the public IP address of the instance you are running on. You can do this by running the following command:

curl ifconfig.me

Once the port-forward is running, you can access the application by opening a browser and navigating to http://<public IP address>:8083. You should see the following:

Once you have confirmed the application is running, you can close the port-forward by pressing ctrl + c.

Next, we will deploy the OpenTelemetry Collector.
