Is it possible to use the Ingress Controller function in Kubernetes without a load balancer (in Digital Ocean).
Is there any other mechanism to allow a domain name to map to a Kubernetes service; for instance if I host two WordPress sites on a Kubernetes cluster:
\==> WP Site 1: Node Port 80 ==> WP Site 2: Node Port 8080
How does a domain name map to the container port 8080 without explicitly entering the port number.
Any help is appreciated.
DNS doesn't support adding port numbers, you need an ingress controller (which essentially acts like a reverse proxy) to do this.
If you install the digital ocean cloud controller manager you'll be able to provision loadbalancers using services with type LoadBalancer. You can then deploy a standard ingress controller, like the nginx ingress controller and give the service type=LoadBalancer.
This then becomes the ingress into your cluster, and you only have a single LoadBalancer, which keeps costs down.
