In this video, you'll learn:
- What is a Kubernetes network policy
- Why do we use a network policy in Kubernetes
- Create a cluster that supports network policy
- Install a network add-on such as Calico
- Create a network policy to restrict access to the pods

👨🏼‍💻 #40daysofKubernetes Challenge:
Join our 40-day challenge and solidify your Kubernetes skills. Details can be found in the "#40daysofkubernetes.md" file on GitHub or by watching our Day 0 video.
📖 Course Schedule:
I'll release 3-4 videos per week and host live Q&A sessions on weekends to answer your questions and guide you through the CKA certification process.
🕵🏻‍♂️ Who Should Watch:
This CKA course is designed for beginners, college students, and working professionals who want to learn Kubernetes from scratch, prepare for the CKA certification exam, or enhance their knowledge. It was designed based on the latest curriculum for the CKA exam in May 2024 and uses 1.30.2 as the Kubernetes version.
Let's start your Kubernetes journey together!

[@SandyLearner]

Hello !!
Also had some queries. Evolving Tools in K8s like Istio, Rancher ,Kustomize and etc.. Apart from CKA and CKAD knowledge, any other knowledge in other tools and Docker Adv required??

[@TechTutorialswithPiyush]

If you understand the fundamentals of Kubernetes in depth and these tools are piece of cake. It can be easily learned. Make sure to learn atleast one tool for each usecase such as k8s package manager --> Helm, ArgoCD for Gitops, image scanning tool, policy as a code, security, vulnerability scanning, kustomize , istio etc

[@divyamsharma5198]

Question: You are referencing the Tiers as worker nodes but stating the network policies in terms of pods, I guess pods would be running the worker nodes. Do you mean that pods running on different nodes can also connect with each other by default?

[@TechTutorialswithPiyush]

Yes, Pods are connected by each other as they are part of the cluster network even if they are on different nodes
