Question

Pointing multiple domains to managed k8s cluster.

Just created my managed k8s cluster and deployed some applications. Can i somehow point a domain/subdomain to each app without setting up additional droplet with proxy(nginx for example), with just DO managed products? P.S. some apps also have more than 1 replicas, so some kind of load balancing will be needed too.

Hey gabe!

For the load balancing, you can create a Kubernetes service [1] pointing to the deployment. Requests coming to it’s IP will automatically be distributed across all the replicas.

For the multiple domains you can:

  • Create a Kubernetes ingress [2] or simply spin up an NGINX/HAProxy deployment that will receive requests from all domains in the same IP and decide to which internal service to send.
  • Expose your ingress controller or NGINX/HAProxy deployment with a Kubernetes load balancer service [3] (which will automatically provision a DO Load Balancer [4] pointing to your nodes for you – $10/mo)
  • OR for a cheaper option, expose them using a ClusterIP with ExternalIPs… This is not recommended due to availability but is $10/mo cheaper than the other option.
  • Point your (sub)domains to the load balancer IP (or droplet IP for the second option) and set up the rules in the ingress definition/nginx or haproxy config.

That’s it :)
