2. Get OAuth Bearer Token from ThousandEyes dashboard

   

   If this token has been generated, you can get it from your admin or revoke it to create a new one.

3. Update the OAuth bearer token

   Encode the token in base64

   echo -n "YOUR_OAUTH_BEARER_TOKEN" | base64
   

   Modify OAuthBearerToken (base64 encoded) in config/deploy/thousandeyes_kubernetes_operator.yaml

4. Install the operator

   kubectl apply -f config/deploy/thousandeyes_kubernetes_operator.yaml
   

5. Verify installation status

   i. Check ThousandEyes Kubernetes Operator pod status

   kubectl get pods | grep thousandeyes
   
     NAME                                                            READY   STATUS    RESTARTS   AGE
     devnet-thousandeyes-kubernetes-operator-564b5d75d-jllzk         1/1     Running   0          108s
   

   ii. Check ThousandEyes CRD status

   kubectl get crd | grep thousandeyes
   
     NAME                                                  CREATED AT

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.
