Quick Start

Let`s run a Nginx web app, then create a Page Load test to monitor this app

1. Create a Nginx web app

   kubectl apply -f config/samples/nginx.yaml
   

2. Check the Nginx pod status

   kubectl get pods -A | grep nginx
   default       nginx-6976ddb986-rxqv6          1/1     Running    0        12s
   

3. Expose Nginx service to Internet Using ngrok

   kubectl apply -f config/samples/ngrok.yaml  
   

4. Check the ngrok pod status

   kubectl get pods -A | grep ngrok
   default       ngrok-5dfd559764-zx9r7          1/1     Running   0         7s
   

5. Get the public URL of this web app

   ./config/samples/public_url.sh
   

   Your public URL for Nginx web app is similar to:

   https://9c5f-64-104-125-230.eu.ngrok.io
   

6. Access this app

   Open your favorite browser and navigate to the public URL.

   You should see the Nginx welcome page which means you have run the app successfully.

7. Update your public URL in config/samples/pageload_cr.yaml

8. Apply the page load test CR

   kubectl apply -f config/samples/pageload_cr.yaml
   

9. Go to ThousandEyes dashboard

   You will find this test on ThousandEyes dashboard.
