What are the key differences between Docker and Kubernetes networking?

Docker networking is simpler and focuses on container-to-container communication, while Kubernetes networking is more complex, managing communication across multiple pods and services.

Can you explain how service discovery works in Kubernetes?

In Kubernetes, service discovery is handled through the use of services, which provide stable IP addresses and DNS names for pods, allowing them to communicate seamlessly.

How does Docker handle networking for containers?

Docker uses a bridge network by default, allowing containers to communicate with each other on the same host, and it can also create overlay networks for multi-host communication.

What are some common networking challenges in Kubernetes?

Common challenges include managing network policies, ensuring service availability, and handling network latency between pods across different nodes.
