Pull Request Description: Add Kerberos Factory to Deployment Guide

Motivation

The current deployment guide lacks a streamlined method for non-technical users to manage Kerberos Agents, which can be cumbersome and error-prone. Adding Kerberos Factory provides a user-friendly interface for managing Kerberos Agents, making the process more accessible and efficient.

Changes Made

1. README.k8s.md and README.microk8s.md:

   • Updated instructions to include Kerberos Factory for easier agent management.
   • Clarified the use of mongodb-configmap.yaml for MongoDB configurations.
   • Added steps to create the kerberos-factory namespace and deploy Kerberos Factory.
   • Included instructions to apply necessary cluster roles for Kerberos Factory.

2. New Configuration Files:

   • kerberos-factory-clusterrole.yaml: Defines the cluster role and binding required for Kerberos Factory to interact with Kubernetes resources.
   • kerberos-factory-deployment.yaml: Deployment configuration for Kerberos Factory.
   • kerberos-factory-service.yaml: Service configuration for Kerberos Factory, using a NodePort for external access.

3. Existing Configuration Updates:

   • data-filtering-deployment.yaml and kerberos-agent-deployment.yaml: Adjusted STORAGE_URI and AGENT_KERBEROSVAULT_URI to use vault-nodeport instead of vault-lb for consistency.
   • mongodb-configmap.yaml: Added a new entry for MONGODB_DATABASE_FACTORY to facilitate Kerberos Factory's MongoDB connection.

Why it Improves the Project

• User-Friendly: Provides a GUI for managing Kerberos Agents, reducing the complexity for non-technical users.
• Efficiency: Streamlines the deployment and management process of Kerberos Agents.
• Consistency: Ensures that all components are using consistent configurations and best practices.
• Scalability: Facilitates easier scaling and management of Kerberos Agents through a centralized interface.

By integrating Kerberos Factory, we enhance the overall usability and maintainability of the project, making it more accessible to a broader audience.
