To find out the exposed IP and Port we can use describe service as we learned in the previous part of the tutorial\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl describe services/kubernetes-bootcamp\n```\n\nCreate an environment variable called NODE_PORT that has a value as the Node port\n\nBounded code example (external data; do not execute automatically):\n```shell\nexport NODE_PORT=\"$(kubectl get services/kubernetes-bootcamp -o go-template='{{(index .spec.ports 0).nodePort}}')\"\necho NODE_PORT=$NODE_PORT\n```\n\nNext, we’ll do a curl to the exposed IP address and port. Execute the command multiple times\n\nBounded code example (external data; do not execute automatically):\n```shell\ncurl http://\"$(minikube ip):$NODE_PORT\"\n```\n\nWe hit a different Pod with every request. This demonstrates that the load-balancing is working.\n\nThe output should be similar to\n\nBounded code example (external data; do not execute automatically):\n```text\nHello Kubernetes bootcamp! | Running on: kubernetes-bootcamp-644c5687f4-wp67j | v=1\nHello Kubernetes bootcamp! | Running on: kubernetes-bootcamp-644c5687f4-hs9dj | v=1\nHello Kubernetes bootcamp! | Running on: kubernetes-bootcamp-644c5687f4-4hjvf | v=1\nHello Kubernetes bootcamp! | Running on: kubernetes-bootcamp-644c5687f4-wp67j | v=1\nHello Kubernetes bootcamp! | Running on: kubernetes-bootcamp-644c5687f4-4hjvf | v=1\n```\n\nIf you're running minikube with Docker Desktop as the container driver, a minikube tunnel is needed. This is because containers inside Docker Desktop are isolated from your host computer.\n\nIn a separate terminal window, execute\n\nBounded code example (external data; do not execute automatically):\n```shell\nminikube service kubernetes-bootcamp --url\n```\n\nThe output looks like this\n\nBounded code example (external data; do not execute automatically):\n```text\nhttp://127.0.0.1:51082\n!  Because you are using a Docker driver on darwin, the terminal needs to be open to run it.\n```\n\nThen use the given URL to access the app\n\nBounded code example (external data; do not execute automatically):\n```shell\ncurl 127.0.0.1:51082\n```\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
