Networking

Kubernetes networking can be difficult to master, but the Kubernetes networking model assists in this aspect by stating that every pod gets its own IP address. The containers inside a pod share the pod's IP address, which allows for uncomplicated communications to take place between the other pods. This means that the pods can easily communicate with the other pods in the cluster using pod IP addresses, without using NAT.
