[Docs] Implementing Kubernetes Network Policies with Meshery

Current State

Meshery Docs are in need of new tutorials with hands-on labs. In these tutorials, we will demonstrate how to implement serverless applications on Kubernetes using Knative with Meshery UI. Through the visual interface of Meshery UI, learners will deploy functions that auto-scale based on traffic, and understand serverless architecture principles without dealing with complex YAML configurations directly.

Desired State

Tutorial will cover the following:

• Introduction to Kubernetes Network Policies and their importance for cluster security
• Setting up isolated namespaces for testing in Meshery Playground
• Creating and deploying sample microservices across namespaces
• Implementing default deny policies to establish a security baseline
• Creating targeted allow policies based on namespace and pod selectors
• Testing and validating network connectivity between services
• Best practices for implementing network segmentation in production environments
