Connecting Applications with Services

Connecting Applications with Services is a Kubernetes tutorial that explains the Kubernetes model for connecting containers. It starts from a continuously running, replicated application and shows how that application can be exposed on a network. The tutorial rests on the assumption built into Kubernetes that pods can communicate with other pods regardless of which host they land on.

  • Explains the Kubernetes model for connecting containers
  • Covers exposing a replicated application on a network
  • Assumes pod-to-pod communication across hosts

Service discovery in the wider platform

Service discovery and load balancing is listed among the features of Kubernetes on the project's home page, alongside automated rollouts and rollbacks, storage orchestration and IPv4/IPv6 dual-stack. These networking capabilities apply wherever a cluster runs, since Kubernetes can be used on on-premises, hybrid or public cloud infrastructure. The project describes itself as a CNCF graduated project.
