What is container networking and why is it important?

Container networking refers to the methods and technologies that allow containers to communicate with each other and with external systems. It's crucial for microservices architecture, enabling seamless interaction between services.

How does container networking differ from traditional networking?

Unlike traditional networking, which relies on physical hardware and static IP addresses, container networking is dynamic and can adapt to the ephemeral nature of containers, allowing for automatic IP assignment and service discovery.

What are some popular container networking solutions?

Some popular container networking solutions include Calico, Flannel, and Weave Net. Each offers unique features for managing network policies and connectivity.

Can you explain how service discovery works in container networking?

Service discovery in container networking allows containers to find and communicate with each other without hardcoding IP addresses. Tools like Consul or Kubernetes' built-in service discovery facilitate this process.
