Chapter 5 – Services and Ingress – Communicating with the Outside World

  1. You would use a ClusterIP service.
  2. You can use the kubectl describe command to see what port on the Nodes a NodePort service is active on.
  3. In a cloud environment where you often have to pay per load balancer, Ingress allows you to specify multiple routing rules while only having to pay for one load balancer.
  4. ExternalName services can be used to easily route to other pieces of infrastructure in your cloud environment – such as managed databases and object storage.
