Kubernetes for the Absolute Beginners - Hands-On - Basics of Networking in Kubernetes

The video tutorial discusses networking in Kubernetes, starting with a single-node cluster and explaining how IP addresses are assigned to pods. It highlights the challenges of networking in multi-node clusters, such as IP conflicts, and emphasizes the need for a networking solution that meets Kubernetes' requirements. Various prebuilt solutions like Calico, Flannel, and Weave Net are introduced to manage networking in Kubernetes clusters, ensuring seamless communication between pods and nodes.

What is the primary IP address used for accessing a Kubernetes node?

• 10.244.0.2

• 192.168.1.10

• 10.244.0.0

• 192.168.1.2

In Kubernetes, what is assigned an IP address instead of a container?

• Service

• Pod

• Cluster

• Node

What is a potential issue when multiple nodes in a Kubernetes cluster have the same internal network address?

• Security vulnerabilities

• Data loss

• IP conflicts

• Increased latency

Which of the following is NOT a requirement for Kubernetes networking?

• All containers must communicate without NAT

• Nodes must communicate with containers

• Containers must communicate with external networks

• Containers must communicate with nodes

Which networking solution is recommended for a VMware environment?

• Flannel

• Weave Net

• Calico

• NXT

What is the role of custom networking solutions like Flannel or Calico in Kubernetes?

• To manage network addresses and enable communication

• To provide security

• To increase storage capacity

• To enhance user interface

Which of the following is a prebuilt solution for Kubernetes networking?
