CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Overview

This is a home infrastructure deployment repository using Ansible for automated server configuration and container deployment. The project follows a "one-button deployment" philosophy for managing a home server environment with various self-hosted services.

Development Commands

Core Commands

• make or make lint - Run linting (yamllint + ansible-lint) on all YAML files
• make deploy - Deploy all configurations to the home server
• make deploy TAGS=sometag - Deploy only specific tagged tasks
• make deploy TARGET=specific-host - Deploy to specific host instead of all
• make check - Run deployment in dry-run mode showing potential changes
• make vault - Edit encrypted Ansible vault file
• make list-tags - List all available Ansible tags
• make list-tasks - List all Ansible tasks

Environment Setup

The project uses Python virtualenv for dependency management:

• Dependencies are locked in requirements.txt (ansible + yamllint)
• Makefile automatically creates .venv/ and installs dependencies
• Vault password is sourced from password manager via .pass.sh

Container Organization

Containers are organized in ansible/roles/podman/tasks/containers/:

• base/ - Core infrastructure containers (Caddy web server, AWS DDNS)
• home/ - Home-specific services (Home Assistant, PartKeepr, Immich photos, Nextcloud, Redis)
• debyltech/ - Personal/business services (Fulfillr)
• skudak/ - Additional services (BookStack wiki, Nextcloud)

Security Model

• Ansible vault for encrypted secrets management
• Password sourced from external password manager
• Git-crypt for repository-level encryption (see .gitattributes)
• SSH key-based authentication to target hosts
• Caddy provides automatic HTTPS with LetsEncrypt certificates
• Built-in security headers and IP-based access restrictions

Key Patterns

Role Structure

Each Ansible role follows standard structure:

• tasks/main.yml - Main task entry point
• defaults/main.yml - Default variables
• handlers/main.yml - Event handlers
• meta/main.yml - Role metadata and dependencies

Container Deployment Pattern

Container tasks follow consistent patterns:

• Firewall configuration
• Container image specification via variables
• Service configuration through imported task files
• Tag-based selective deployment

Tagging Strategy

Tasks are tagged by service/component for selective deployment:

• caddy - Web server tasks (replaced nginx)
• ddns - Dynamic DNS tasks
• drone - CI/CD tasks (decommissioned)
• hass - Home Assistant tasks
• Common infrastructure tags like common, ssl

Configuration Files

• ansible.cfg - Ansible configuration with performance optimizations
• .yamllint.yml - YAML linting rules (braces disabled)
• .lint-vars.sh - Ansible-lint skip configuration
• requirements.txt - Python dependencies with pinned versions

Target Environment

• Single target host: home.bdebyl.net
• OS: Fedora (ansible_user: fedora)
• Container runtime: Podman
• Web server: Caddy with automatic HTTPS and built-in security (replaced nginx + ModSecurity)
• All services accessible via HTTPS with automatic certificate renewal
• CI/CD: Drone CI infrastructure completely decommissioned
