-# To-Do List Application on Kubernetes
+# Aplikácia To-Do List v Kubernetes
 
 ## Application Description
 
@@ -9,76 +9,20 @@ This is a simple To-Do List web application that allows users to:
 - Filter tasks by their status (All, Active, Completed)
 - Reorder tasks using drag-and-drop functionality
 
-The application uses local storage to persist tasks and allows users to manage their daily tasks efficiently.
 
-## Container Images Used
+# Aplikácia To-Do List v Kubernetes
 
-1. **todo-web-app:latest**: 
+## Popis
-   - Custom image based on nginx:alpine
-   - Contains the static web files (HTML, CSS, JavaScript) for the To-Do List application
-   - Serves the web interface on port 80
 
-2. **redis:alpine**: 
+Tento projekt nasadzuje aplikáciu "To-Do List" do Kubernetes. Používa niekoľko komponentov, ako sú deploymenty pre frontend a backend, StatefulSet pre ukladanie dát a služby na interakciu medzi komponentami.
-   - Official Redis image based on Alpine Linux
-   - Used in the StatefulSet for data persistence
-   - Stores task data on a persistent volume
-   - Runs on port 6379
 
-## Kubernetes Objects
+## Požiadavky
 
-1. **Namespace** (`todo-app-ns`):
+- **Kubernetes** (lokálne cez Minikube alebo v cloude)
-   - Isolates all the application resources in a dedicated namespace
+- **kubectl** na správu klastru
+- **Docker** na prácu s kontajnermi
+- Lokálny alebo cloudový Docker repozitár (napríklad Docker Hub)
 
-2. **Deployment** (`todo-web-app`):
-   - Manages the web application containers
-   - Maintains 2 replicas for high availability
-   - Defines resource limits and requests
-
-3. **StatefulSet** (`todo-data-manager`):
-   - Manages Redis instances for data persistence
-   - Uses persistent storage to maintain task data
-   - Ensures data consistency during pod restarts
-
-4. **PersistentVolume** (`todo-app-pv`):
-   - Provides storage resources for the application
-   - Uses local storage on the host at `/mnt/data/todo-app`
-   - 1GB capacity for storing task data
-
-5. **PersistentVolumeClaim** (`todo-app-pvc`):
-   - Claims storage from the PersistentVolume
-   - Used by the StatefulSet for data persistence
-
-6. **Services**:
-   - `todo-web-service`: NodePort service exposing the web application
-   - `todo-data-service`: Headless service for the StatefulSet
-
-## Network and Volume Configuration
-
-### Networks
-- The application components communicate within the Kubernetes cluster using services
-- `todo-web-service` exposes the web interface externally using NodePort
-- `todo-data-service` provides internal DNS-based service discovery for the StatefulSet
-
-### Volumes
-- The application uses a persistent volume mounted at `/mnt/data/todo-app` on the host
-- This volume is mounted into the Redis container at `/data` to persist task data
-- The volume uses the `manual` storage class with ReadWriteOnce access mode
-
-## Container Configuration
-
-### Web Application Container
-- Based on nginx:alpine
-- Configured to serve static content from `/usr/share/nginx/html`
-- Resource limits: 500m CPU, 256Mi memory
-- Resource requests: 100m CPU, 128Mi memory
-
-### Redis Container
-- Based on redis:alpine
-- Data directory mounted to persistent storage
-- Resource limits: 300m CPU, 256Mi memory
-- Resource requests: 100m CPU, 128Mi memory

-### Accessing the Web Interface
-1. After starting the application, note the NodePort displayed in the terminal
-2. Open your web browser and navigate to `http://localhost:<NodePort>`
-3. You should see the To-Do List application interface
-4. Start adding tasks, marking them as completed, or deleting them as needed

-## Troubleshooting
-- If pods aren't starting, check the pod status: `kubectl get pods -n todo-app-ns`
-- For detailed pod issues: `kubectl describe pod <pod-name> -n todo-app-ns`
-- To view logs: `kubectl logs <pod-name> -n todo-app-ns`
