# Repository Overview



## Motivation



This repository is dedicated to demonstrating the process of establishing a robust **application architecture** on a Minikube cluster using **Istio**. The focus is on configuring and deploying infrastructure components to ensure secure communication, namespace isolation, and effective traffic routing with Istio's advanced capabilities like **path-based routing**.



### Key Objectives:

1. Establish secure namespaces for application components.

2. Deploy and configure core services with a focus on architecture rather than application logic.

3. Utilize Istio for:

   - Path-based routing for service traffic.

   - Enabling observability and secure communication.

4. Showcase foundational setups that can scale with additional features like **circuit-breaking** and **mTLS enforcement**.



---



## Intended Audience



This repository is for developers and architects who:

- Want to learn how to implement Kubernetes and Istio for application deployment.

- Need a starting point for designing secure and scalable service architectures.

- Are looking for examples of Istio configurations on a local Minikube setup.



---



## Repository Structure



### 1. **App Development**

   - Contains individual application files for four apps:

     - **Python source files (`.py`)**: (Dummy)Application logic for each app.

     - **`requirements.txt`**: Dependencies for each app.

     - **Dockerfile**: Used to containerize each app.

   - Apps included:

     1. Control Plane

     2. Guardrails

     3. Summariser

     4. Mock LLM



### 2. **App Deployment**

   - Houses the core infrastructure setup for deploying the application architecture on Minikube, including:

     - Istio installation and configuration.

     - Namespace creation with Istio injection enabled.

     - Ingress gateway setup for path-based routing.



---



## Focus of the Repository



This repository does **not** focus on the development of application business logic. Instead, it serves as a guide to:

- Set up a Kubernetes environment with Istio.

- Manage secure and scalable application deployment.

- Configure essential Istio features for traffic management and security.



---

For detailed application logic, users are encouraged to integrate their own business requirements into the provided deployment architecture.
