Understanding the Kubernetes networking model
Kubernetes is designed to facilitate the desired state management to host containerized workloads – these workloads take advantage of sharable compute resources. Kubernetes networking resolves the challenge of how to allow different Kubernetes components to communicate with each other and applications on Kubernetes to communicate with other applications, as well as the services outside of the Kubernetes cluster.
Hence, the official documentation summarizes those networking challenges as container-to-container, pod-to-pod, pod-to-service, external-to-service, and node-to-node communications. Now, we are going to break them down one-by-one in this section.
Container-to-container communication
Container-to-container communication mainly refers to the communication between containers inside a pod – a multi-container pod is a good example of this. A multi-container pod is a pod that contains multiple containers and is...
