-You can retrieve the external IP address in the environment variable `SVC_IP` using the following command:
-

-
-```bash
-SVC_IP=$(kubectl -n httpbin  get svc httpbin --output jsonpath='{.status.loadBalancer.ingress[0].ip}')

+You must set the environment variable `SVC_IP` with the external IP address and port used to access the `httpbin` service from the test script.
 
-```Powershell
-$Env:SVC_IP=$(kubectl -n httpbin  get svc httpbin --output jsonpath='{.status.loadBalancer.ingress[0].ip}')
