I have been playing with Digital Ocean's new managed Kubernetes service. I have created a new cluster using Digital Ocean's dashboard and, seemingly, successfully deployed my yaml file (attached).
running in context kubectl get services
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE api-svc NodePort XX.XXX.XXX.XXX <none> 8080:30000/TCP 2h kubernetes ClusterIP XX.XXX.X.X <none> 443/TCP 2h
My question is, how do I go exposing my service without a load balancer?
I have been able to do this locally using minikube. To get the cluster IP I run minikube ip
and use port number 30000
, as specified in my nodePort config, to reach the api-svc
service.
From what I understand, Digital Ocean's managed service abstracts the master node away. So where would I find the public IP address to access my cluster?
Thank you in advance!

You can hit any of your worker nodes' ip. Example http://worker-node-ip:30000/. You can get the worker nodes ip from the digitalocean dashboard or use doctl cli.
