Kubernetes supports two ways of doing this: NodePorts and LoadBalancers. The Service created in the last section already used NodePort, so your nginx HTTPS replica is ready to serve traffic on the internet if your node has a public IP.\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl get svc my-nginx -o yaml | grep nodePort -C 5\n  uid: 07191fb3-f61a-11e5-8ae5-42010af00002\nspec:\n  clusterIP: 10.0.162.149\n  ports:\n  - name: http\n    nodePort: 31704\n    port: 8080\n    protocol: TCP\n    targetPort: 80\n  - name: https\n    nodePort: 32453\n    port: 443\n    protocol: TCP\n    targetPort: 443\n  selector:\n    run: my-nginx\n```\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl get nodes -o yaml | grep ExternalIP -C 1\n    - address: 104.197.41.11\n      type: ExternalIP\n    allocatable:\n--\n    - address: 23.251.152.56\n      type: ExternalIP\n    allocatable:\n...\n\n$ curl https://<EXTERNAL-IP>:<NODE-PORT> -k\n...\n<h1>Welcome to nginx!</h1>\n```\n\nLet's now recreate the Service to use a cloud load balancer. Change the Type of my-nginx Service from NodePort to LoadBalancer\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl edit svc my-nginx\nkubectl get svc my-nginx\n```\n\nBounded code example (external data; do not execute automatically):\n```text\nNAME       TYPE           CLUSTER-IP     EXTERNAL-IP        PORT(S)               AGE\nmy-nginx   LoadBalancer   10.0.162.149     xx.xxx.xxx.xxx     8080:30163/TCP        21s\n```\n\nBounded code example (external data; do not execute automatically):\n```text\ncurl https://<EXTERNAL-IP> -k\n...\n<title>Welcome to nginx!</title>\n```\n\nThe IP address in the EXTERNAL-IP column is the one that is available on the public internet. The CLUSTER-IP is only available inside your cluster/private cloud network.\n\nNote that on AWS, type LoadBalancer creates an ELB, which uses a (long) hostname, not an IP. It's too long to fit in the standard kubectl get svc output, in fact, so you'll need to do kubectl describe service my-nginx to see it. You'll see something like this …\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
