Deployment と Service 作成

$ kubectl apply -f https://gist.githubusercontent.com/gowatana/3b065d9d800d2b65b82e339bcae5310a/raw/httpd-nodeport.yml

アドレスとポート番号を取得

$ IP=$(kubectl get endpoints  kubernetes -o jsonpath='{.subsets[0].addresses[0].ip}')
$ PORT=$(kubectl get service httpd-svc -o jsonpath='{.spec.ports[0].nodePort}')

接続確認

$ echo http://$IP:$PORT
$ curl http://$IP:$PORT
<h1>httpd on Karbon</h1> httpd-5db7885456-kl8fd
