Summary

Kubernetes networking is essential for the effective communication between the components of its distributed system, such as containers, pods, and services. The platform employs a flat network structure to simplify the network configuration, allowing pods to communicate seamlessly without the need for Network Address Translation (NAT). By addressing the port allocation issue with an IP-per-pod approach, Kubernetes ensures each pod has a unique IP, facilitating connectivity within the cluster. The use of Container Network Interface (CNI) APIs provides flexibility in configuring network resources, and services offer a stable network access point despite the ephemeral nature of pod IPs. DNS plays a crucial role in service discovery, enabling pods to use consistent DNS names instead of IP addresses. Earthly, a tool for improving continuous integration, integrates smoothly with Kubernetes, offering enhanced build processes.
