Deployment Guide

Local Development

Prerequisites

• Python 3.13+ (required by pyproject.toml)
• uv — Fast Python package manager
• Google Sheets API credentials (service account JSON)

Setup

git clone <repo-url>
cd fuj-management

# Install dependencies
uv sync

# Configure credentials
mkdir -p .secret
cp /path/to/credentials.json .secret/fuj-management-bot-credentials.json

# Optional: Set Fio API token for richer bank data
export FIO_API_TOKEN=your_token_here

# Start the web dashboard
make web
# → Flask server at http://localhost:5001

Makefile Targets

Target	Command	Description
help	make help	List all available targets
venv	make venv	Sync virtual environment with pyproject.toml
fees	make fees	Print fee calculation table
match	make match	(Legacy) Direct bank matching
web	make web	Start Flask dashboard on port 5001
sync	make sync	Sync last 30 days of bank transactions
sync-2026	make sync-2026	Sync full year 2026 transactions
infer	make infer	Auto-fill Person/Purpose in the sheet
reconcile	make reconcile	Print CLI balance report
test	make test	Run test suite
test-v	make test-v	Run tests with verbose output
image	make image	Build Docker image
run	make run	Run Docker container locally

The Makefile includes automatic venv management: targets that need Python depend on .venv/.last_sync, which triggers uv sync when pyproject.toml changes.

Docker Container

Building

make image
# → docker build -t fuj-management:latest -f build/Dockerfile .

Dockerfile Details

Base image: python:3.13-alpine

Build stages:

1. Install system packages (bash, tzdata)
2. Set timezone to Europe/Prague
3. Install Python dependencies via pip
4. Copy application files (app.py, scripts/, templates/, Makefile)
5. Copy entrypoint script

Exposed port: 5001

Health check: wget -q -O /dev/null http://localhost:5001/ every 60s

Running Locally via Docker

make run
# → docker run -it --rm -p 5001:5001 fuj-management:latest

# With credentials and environment:
docker run -it --rm \
  -p 5001:5001 \
  -v $(pwd)/.secret:/app/.secret:ro \
  -e FIO_API_TOKEN=your_token \
  -e BANK_ACCOUNT=CZ8520100000002800359168 \
  fuj-management:latest

Entrypoint

The build/entrypoint.sh script simply runs:

exec python3 /app/app.py

This uses Flask's built-in server directly. For a production deployment, consider adding gunicorn or waitress (noted as a TODO in the entrypoint).

Environment Variables

Variable	Default	Description
BANK_ACCOUNT	CZ8520100000002800359168	IBAN for QR code generation
FIO_API_TOKEN	(none)	Fio REST API token
PYTHONUNBUFFERED	1 (set in Dockerfile)	Ensures real-time log output

CI/CD Pipeline

Gitea Actions

The project uses two Gitea Actions workflows:

1. Build and Push (build.yaml)

Triggers:

• Push of any tag
• Manual dispatch (with custom tag input)

Steps:

1. Checkout code
2. Login to Gitea container registry (gitea.home.hrajfrisbee.cz)
3. Build Docker image using build/Dockerfile
4. Push to gitea.home.hrajfrisbee.cz/<owner>/<repo>:<tag>

Tag resolution: Uses the git tag name. For manual dispatch, uses the provided input.

2. GitOps image update (gitops-update.yaml)

Triggers:

• Completion of a successful "Build and Push" run
• Manual dispatch (with tag, dry_run and uh_cli_version inputs)

Steps:

1. Install tea and uh-cli
2. Resolve the image tag of the Go image that was just built
3. Open a PR in kacerr/home-kubernetes bumping the fuj-management Deployment (namespace fuj) to that image

The cluster picks the change up once that PR is merged. CI does not talk to the cluster directly.

The earlier kubernetes-deploy.yaml workflow (Vault → Kanidm → kubectl) was removed on 2026-10-08. It never deployed anything and printed credentials to the job log.

Required secrets:

Secret	Purpose
REGISTRY_TOKEN	Docker registry authentication
GITOPS_TOKEN	Gitea token with write and PR access to home-kubernetes

Infrastructure Topology

Gitea (git push / tag)
   │
   ├── build.yaml → Docker Build → Gitea Container Registry
   │                                  (gitea.home.hrajfrisbee.cz)
   │
   └── gitops-update.yaml → PR in home-kubernetes → K8s Cluster

This is a self-hosted infrastructure stack:

• Gitea for git hosting and CI/CD
• HashiCorp Vault for secret management
• Kanidm for identity/OIDC
• Kubernetes for container orchestration

Credentials Management

Google Sheets API

The system uses a Google Cloud service account for accessing the Payments Google Sheet. The credentials file must be:

• Stored at .secret/fuj-management-bot-credentials.json
• In Google Cloud service account JSON format
• The service account must be shared (as editor) on the target Google Sheet

For local development with OAuth2 (personal Google account), the system also supports the OAuth2 installed app flow — it will generate a token.pickle file on first use.

Fio Bank API

Optional. Set the FIO_API_TOKEN environment variable. The token is generated in Fio internetbanking under Settings → API.

Rate limit: 1 request per 30 seconds per token.
