-## Table of Contents
-
-- [Table of Contents](#table-of-contents)
-- [1. Design Document (design.md)](#1-design-document-designmd)
-
-The design document is the first deliverable for your project.
-We separated this out as a separate deliverable, with its own deadline, to ensure that you have a clear plan before you start coding.
-This part only needs a cursory review by the teaching staff to ensure it is sufficiently comprehensive, while still realistic.
-The teaching staff will assign you to a project mentor who will provide guidance and support throughout the development process.
-
-## 1. Design Document (design.md)
-
-You are required to prepare a design document for your application.
-The design doc should be brief, well-organized and easy to understand.
-The design doc should be prepared in markdown format and named `design.md` and submitted in the project group's repository.
-Remember that you can use [mermaid diagrams](https://github.com/mermaid-js/mermaid#readme) in markdown files.
-
-The design doc **should include** the following sections:
-
-- **Overview**: A brief description of the application and its purpose.
-- **Architecture**: The high-level architecture of the application, including components, interactions, and data flow.
-- **Technologies**: The cloud computing technologies or services used in the application.
-- **Deployment**: The deployment strategy for the application, including any infrastructure requirements.
-
-The design document should be updated throughout the development process and reflect the final implementation of your project.
-
-Optional sections may include:
-
-- Security: The security measures implemented in the application to protect data and resources.
-- Scalability: The scalability considerations for the application, including load balancing and auto-scaling.
-- Monitoring: The monitoring and logging strategy for the application to track performance and detect issues.
-- Disaster Recovery: The disaster recovery plan for the application to ensure business continuity in case of failures.
-- Cost Analysis: The cost analysis of running the application on the cloud, including pricing models and cost-saving strategies.
-- References: Any external sources or references used in the design document.
+# Personal Finance Tracker
+## Folder Structure

 **Brief Description**:
-Our application is a finance tracker, so a person can easily track his cash flow
-through multiple bank accounts. Person can label transactions with custom categories
-and later filter by them.
+Our application allows users to easily track their cash flow
+through multiple bank accounts. Users can label their transactions with custom categories that can be later used for
+filtering and visualization. New transactions are automatically fetched in the background.
 
 ## Architecture Overview
-Our system is a full‑stack web application composed of a React frontend, a FastAPI backend, a PostgreSQL database, and asynchronous background workers powered by Celery with RabbitMQ. Redis is available for caching/kv and may be used by Celery as a result backend. The backend exposes REST endpoints for authentication (email/password and OAuth), users, categories, and transactions. A thin controller layer (FastAPI routers) lives under app/api. Infrastructure for Kubernetes is provided via OpenTofu (Terraform‑compatible) modules and the application is packaged via a Helm chart.
+
+Our system is a full‑stack web application composed of a React frontend, a FastAPI backend,
+a asynchronousMariaDB database with Maxscale, and background workers powered by Celery with RabbitMQ.
+The backend exposes REST endpoints for authentication (email/password and OAuth), users, categories,
+transactions, exchange rates and bank APIs. Infrastructure for Kubernetes is managed via Terraform/OpenTofu and
+the application is packaged via a Helm chart. This all is deployed on private TalosOS cluster running on Proxmox VE with
+CI/CD and with public access over Cloudflare tunnels. Static files for frontend are served via Cloudflare pages.
+Other services deployed in the cluster includes Longhorn for persistent storage, Prometheus with Grafana for monitoring.
 
 ### High-Level Architecture

+flowchart TB
+    n3(("User")) <--> client["Frontend"]
+    proc_queue["Message Queue"] --> proc_queue_worker["Worker Service"]
+    proc_queue_worker -- SMTP --> ext_mail[("Email Service")]
+    proc_queue_worker <-- HTTP request/response --> ext_bank[("Bank API")]
+    proc_queue_worker <--> db[("Database")]
+    proc_cron["Cron"] <-- HTTP request/response --> svc["Backend API"]
     svc --> proc_queue
-    svc <--> db[(Database)]
-    svc <--> cache[(Cache)]
+    n2["Cloudflare tunnel"] <-- HTTP request/response --> svc
+    svc <--> db
+    svc <-- HTTP request/response --> api[("UniRate API")]
+    client <-- HTTP request/response --> n2
 ```
 
+The workflow works in the following way:
+
+- Client connects to the frontend. After login, frontend automatically fetches the stored transactions from
+  the database via the backend API and currency rates from UniRate API.
+- When the client opts for fetching new transactions via the Bank API, cron will trigger periodic fetching
+  using background worker.
+- After successful load, these transactions are stored to the database and displayed to the client
+
+### Features
+
+- The stored transactions are encrypted in the DB for security reasons.
+- For every pull request the full APP is deployed on a separate URL and the tests are run by github CI/CD
+- On every push to main, the production app is automatically updated
+- UI is responsive for mobile devices
+- Slow operations (emails, transactions fetching) are handled
+  in the background by Celery workers.
+- App is monitored using prometheus metrics endpoint and metrics are shown in Grafana dashboard.
+
 ### Components
 
-- Frontend (frontend/): React + TypeScript app built with Vite. Talks to the backend via REST, handles login/registration, shows latest transactions, filtering, and allows adding transactions.
-- Backend API (backend/app): FastAPI app with routers under app/api for auth, categories, and transactions. Uses FastAPI Users for auth (JWT + OAuth), SQLAlchemy ORM, and Pydantic v2 schemas.
-- Worker service (backend/app/workers): Celery worker handling asynchronous tasks (e.g., sending verification emails, future background processing).
-- Database (PostgreSQL): Persists users, categories, transactions; schema managed by Alembic migrations.
-- Message Queue (RabbitMQ): Transports background jobs from the API to the worker.
-- Cache/Result Store (Redis): Available for caching or Celery result backend.
-- Infrastructure as Code (tofu/): OpenTofu modules provisioning cluster services (RabbitMQ, Redis, Argo CD, cert-manager, Cloudflare tunnel, etc.).

+- Frontend available at: http://localhost:5173
 
-If needed, adjust compose services/ports in compose.yml.
+## Build Instructions
 
+### Backend
+
+App is separated into backend and frontend so it also needs to be built separately. Backend is build into docker image
+and frontend is deployed as static files.
+
+```bash
+cd 7project/backend
+# Dont forget to set correct image tag with your registry and name
+# For example lukastrkan/cc-app-demo or gitea.ltrk.dev/lukas/cc-app-demo
+docker buildx build --platform linux/amd64,linux/arm64 -t CHANGE_ME --push .
+```
+
+### Frontend
+
+```bash
+cd project7/src/frontend
+npm ci
+npm run build
+```
 
 ## Deployment Instructions
 
-### Local (Docker Compose)
+Deployment is tested on TalosOS cluster with 1 control plane and 4 workers, cluster needs to be setup and configured
+manually. Terraform/OpenTofu is then used to deploy base services to the cluster. App itself is deployed automatically
+via GitHub actions and Helm chart. Frontend files are deployed to Cloudflare pages.
 
-Described in the previous section (Manual Local Run)
+### Setup Cluster
 
-### Kubernetes (via OpenTofu + Helm)
+Deployment should work on any Kubernetes cluster. However, we are using 4 TalosOS virtual machines (1 control plane, 3
+workers)
+running on top of Proxmox VE.
+
+1) Create at least 4 VMs with TalosOS (4 cores, 8 GB RAM, 200 GB disk)
+2) Install talosctl for your OS: https://docs.siderolabs.com/talos/v1.10/getting-started/talosctl
+3) Generate Talos config
+4) Navigate to tofu directory
+
+```bash
+cd 7project/src/tofu
+````
+
+5) Set IP addresses in environment variables
+
+```bash
+CONTROL_PLANE_IP=<control-plane-ip>
+WORKER1_IP=<worker1-ip>
+WORKER2_IP=<worker2-ip>
+WORKER3_IP=<worker3-ip>
+WORKER4_IP=<worker4-ip>
+....
+```
+
+6) Create config files
+
+```bash
+# change my-cluster to your desired cluster name
+talosctl gen config my-cluster https://$CONTROL_PLANE_IP:6443
+```
+
+7) Edit the generated configs
+
+Apply the following changes to `worker.yaml`:
+
+1) Add mounts for persistent storage to `machine.kubelet.extraMounts` section:
+
+```yaml
+extraMounts:
+  - destination: /var/lib/longhorn
+    type: bindind.
+    source: /var/lib/longhorn
+    options:
+      - bind
+      - rshared
+      - rw
+```
+
+2) Change `machine.install.image` to image with extra modules:
+
+```yaml
+image: factory.talos.dev/metal-installer/88d1f7a5c4f1d3aba7df787c448c1d3d008ed29cfb34af53fa0df4336a56040b:v1.11.1
+```
+
+or you can use latest image generated at https://factory.talos.dev with following options:
+
+- Bare-metal machine
+- your Talos os version
+- amd64 architecture
+- siderolabs/iscsi-tools
+- siderolabs/util-linux-tools
+- (Optionally) siderolabs/qemu-guest-agent
+
+Then copy "Initial Installation" value and paste it to the image field.
+
+3) Add docker registry mirror to `machine.registries.mirrors` section:
+
+```yaml
+registries:
+  mirrors:
+    docker.io:
+      endpoints:
+        - https://mirror.gcr.io
+        - https://registry-1.docker.io
+```
+
+8) Apply configs to the VMs
+
+```bash
+talosctl apply-config --insecure --nodes $CONTROL_PLANE_IP --file controlplane.yaml
+talosctl apply-config --insecure --nodes $WORKER1_IP --file worker.yaml
+talosctl apply-config --insecure --nodes $WORKER2_IP --file worker.yaml
+talosctl apply-config --insecure --nodes $WORKER3_IP --file worker.yaml
+talosctl apply-config --insecure --nodes $WORKER4_IP --file worker.yaml
+```
+
+9) Boostrap the cluster and retrieve kubeconfig
+
+```bash
+export TALOSCONFIG=$(pwd)/talosconfig
+talosctl config endpoint https://$CONTROL_PLANE_IP:6443
+talosctl config node $CONTROL_PLANE_IP
+
+talosctl bootstrap
+
+talosctl kubeconfig .
+```
+
+You can now use k8s client like https://headlamp.dev/ with the generated kubeconfig file.
+
+### Install base services to the cluster
+
+1) Copy and edit variables
 
-1) Provision platform services (RabbitMQ/Redis/ingress/tunnel/etc.) with OpenTofu
 ```bash
-cd tofu
-# copy and edit variables
 cp terraform.tfvars.example terraform.tfvars
-# authenticate to your cluster/cloud as needed, then:
+```
+
+- `metallb_ip_range` - set to range available in your network for load balancer services
+- `mariadb_password` - password for internal mariadb user
+- `mariadb_root_password` - password for root user
+- `mariadb_user_name` - username for admin user
+- `mariadb_user_host` - allowed hosts for admin user
+- `mariadb_user_password` - password for admin user
+- `metallb_maxscale_ip`, `metallb_service_ip`, `metallb_primary_ip`, `metallb_secondary_ip` - IPs for database
+  cluster,  
+  set them to static IPs from the `metallb_ip_range`
+- `s3_enabled`, `s3_bucket`, `s3_region`, `s3_endpoint`, `s3_key_id`, `s3_key_secret` - S3 compatible storage for
+  backups (optional)
+- `phpmyadmin_enabled` - set to false if you want to disable phpmyadmin
+- `rabbitmq-password` - password for RabbitMQ
+
+- `cloudflare_account_id` - your Cloudflare account ID
+- `cloudflare_api_token` - your Cloudflare API token with permissions to manage tunnels and DNS
+- `cloudflare_email` - your Cloudflare account email
+- `cloudflare_tunnel_name` - name for the tunnel
+- `cloudflare_domain` - your domain name managed in Cloudflare
+
+2) Deploy without Cloudflare module first
+
+```bash
 tofu init
-tofu plan
+tofu apply -exclude modules.cloudflare
+```
+
+3) Deploy rest of the modules
+
+```bash
 tofu apply
 ```
 
-2) Deploy the app using Helm
-```bash
-# Set the namespace
-kubectl create namespace myapp || true
+### Configure deployment
 
-# Install/upgrade the chart with required values
-helm upgrade --install myapp charts/myapp-chart \
-  -n myapp \
-  -f charts/myapp-chart/values.yaml \
-  --set image.backend.repository=myorg/myapp-backend \
-  --set image.backend.tag=latest \
-  --set env.BACKEND_URL="https://myapp.example.com" \
-  --set env.FRONTEND_URL="https://myapp.example.com" \
-  --set env.SECRET="CHANGE_ME_SECRET"
-```
-Adjust values to your registry and domain. The chart’s NOTES.txt includes additional examples.
-
-3) Expose and access
-- If using Cloudflare Tunnel or an ingress, configure DNS accordingly (see tofu/modules/cloudflare and deployment/tunnel.yaml).
-- For quick testing without ingress:
-```bash
-kubectl -n myapp port-forward deploy/myapp-backend 8000:8000
-kubectl -n myapp port-forward deploy/myapp-frontend 5173:80
-```
-
-### Verification
-
-```bash
-# Check pods
-kubectl -n myapp get pods
-
-# Backend health
-curl -i http://127.0.0.1:8000/
-# OpenAPI
-open http://127.0.0.1:8000/docs
-
-# Frontend (if port-forwarded)
-open http://localhost:5173
-```
+1) Create self-hosted runner with access to the cluster or make cluster publicly accessible
+2) Change `jobs.deploy.runs-on` in `.github/workflows/deploy-prod.yml` and in `.github/workflows/deploy-pr.yaml` to your
+   runner label
+3) Add variables to GitHub in repository settings:
+    - `PROD_DOMAIN` - base domain for deployments (e.g. ltrk.cz)
+    - `DEV_FRONTEND_BASE_DOMAIN` - base domain for your cloudflare pages
+4) Add secrets to GitHub in repository settings:
+    - CLOUDFLARE_ACCOUNT_ID - same as in tofu/terraform.tfvars
+    - CLOUDFLARE_API_TOKEN - same as in tofu/terraform.tfvars
+    - DOCKER_USER - your docker registry username
+    - DOCKER_PASSWORD - your docker registry password

+    - UNIRATE_API_KEY
+5) On Github open Actions tab, select "Deploy Prod" and run workflow manually
 
 ## Testing Instructions
 
-### Unit Tests
+The tests are located in 7project/backend/tests directory. All tests are run by GitHub actions on every pull request and
+push to main.
+See the workflow [here](../.github/workflows/run-tests.yml).
+
+If you want to run the tests locally, the preferred way is to use a [bash script](backend/test_locally.sh)
+that will start a test DB container with [docker compose](backend/docker-compose.test.yml)  and remove it afterwards.
 
 ```bash
-# Commands to run unit tests
-# For example:
-# go test ./...
-# npm test
+cd 7project/src/backend 
+bash test_locally.sh
+```
+
+### Unit Tests
+
+There are only 5 basic unit tests, since our services logic is very simple
+
+```bash
+bash test_locally.sh --only-unit
 ```
 
 ### Integration Tests
 
+There are 9 basic unit tests, testing the individual backend API logic
+
 ```bash
-# Commands to run integration tests
-# Any setup required for integration tests
+bash test_locally.sh --only-integration
 ```
 
 ### End-to-End Tests
 
+There are 7 e2e tests, testing more complex app logic
+
 ```bash
-# Commands to run e2e tests
-# How to set up test environment
+bash test_locally.sh --only-e2e
 ```

 ### Challenges Faced
 
-[Describe the main challenges and how you overcame them]
+#### Slow cluster performance
+
+This was caused by single SATA SSD disk running all VMs. This was solved by adding second NVMe disk just for Talos VMs.
+
+#### Stucked IaC deployment
+
+If the deployed module (helm chart for example) was not configured properly, it would get stuck and timeout resulting in
+namespace that cannot be deleted.
+This was solved by using snapshots in Proxmox and restoring if this happened.
 
 ### If We Did This Again
 
+#### Different framework
+
+FastAPI lacks usable build in support for database migrations and implementing Alembic was a bit tricky.
+Tricky was also integrating FastAPI auth system with React frontend, since there is no official project template.
+Using .NET (which we considered initially) would probably solve these issues.
+
 [What would you do differently? What worked well that you'd keep?]
 
 ### Individual Growth
 
-#### [Team Member 1 Name]
+#### [Lukas]
 
-[Personal reflection on growth, challenges, and learning]
+This course finally forced me to learn kubernetes (been on by TODO list for at least 3 years).
+I had some prior experience with terraform/opentofu from work but this improved by understanding of it.
 
-#### [Team Member 2 Name]
+The biggest challenge for me was time tracking since I am used to tracking to projects, not to tasks.
+(I am bad even at that :) ).
+
+It was also interesting experience to be the one responsible for the initial project structure/design/setup
+used not only by myself.
+
+#### [Dejan]
+
+Since I do not have a job, this project was probably the most complex one I have ever worked on.
+It was also the first school project where I was encouraged to use AI.
