 ## 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.

 ```
 
 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
+  the database via the backend API and currency rates from UniRate API.
-- When the client opts for fetching new transactions via the Bank API, the backend delegates the task 
+- When the client opts for fetching new transactions via the Bank API, cron will trigger periodic fetching
-to a background worker service via the Message queue.
+  using background worker.
 - After successful load, these transactions are stored to the database and displayed to the client
-- There is also a Task planner, that executes periodic tasks, like fetching new transactions automatically from the Bank API
+
+### 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.

 ## Deployment Instructions
+
 ### Setup Cluster
-Deployment should work on any Kubernetes cluster. However, we are using 4 TalosOS virtual machines (1 control plane, 3 workers) 
+
+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 4 VMs with TalosOS
+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
-```bash
+4) Navigate to tofu directory
-# TODO: add commands
-```
-4) Edit the generated worker.yaml
-- add google container registry mirror
-- add modules from config generator 
-- add extramounts for persistent storage
-- add kernel modules
 
-5) Apply the config to the VMs
 ```bash
-#TODO: add config apply commands
+cd 7project/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) Verify the cluster is up
+6) Create config files
+
 ```bash
+# change my-cluster to your desired cluster name
+talosctl gen config my-cluster https://$CONTROL_PLANE_IP:6443
 ```
 
-7) Export kubeconfig
+7) Edit the generated configs
-```bash
+
-# TODO: add export command
+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
 
-### Install
-1) Install base services to cluster
 ```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`

 ## Testing Instructions
-The tests are located in 7project/backend/tests directory
+
-If you want to test locally, you have to have the DB running locally as well (start the docker compose in /backend).
+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 is to use a [bash script](backend/test-with-ephemeral-mariadb.sh)
+that will start a [test DB container](backend/docker-compose.test.yml) and remove it afterward.
+
 ```bash
-cd backend
+cd 7project/backend 
+bash test-with-ephemeral-mariadb.sh
 ```

 ### Challenges Faced
 
+#### 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.
+
 [Describe the main challenges and how you overcame them]
 
 ### 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]
+
+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.
+
+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.
