Certbot

Description

This Ansible role automates the installation and configuration of Certbot, a free and open-source tool for automating the deployment of Let’s Encrypt certificates. It also handles the setup of DNS plugins for ACME challenges.

Overview

Optimized for Archlinux, this role ensures secure SSL/TLS certificate generation with minimal manual intervention. It supports both webroot and DNS-01 validation methods, providing flexibility based on your infrastructure needs.

Key Features

• Automatic Installation: Installs certbot and the necessary DNS plugin via pacman.

• Dynamic DNS Plugin Support: Automatically installs the correct certbot-dns-<provider> package based on your selected challenge method.

• Credential Management: Creates secure credential files for DNS API tokens when using DNS-01 validation.

• Idempotent Execution: Tasks are intelligently executed only once per playbook run.

Cosmos

The diagram places Certbot in the Infinito.Nexus cosmos: the components it deploys (capabilities), the central services it consumes (dependencies), and its outward reach (federation and bridged external networks).

Solid 1:1 edges are fixed relationships; dashed 0..1 edges are conditional (enabled only in matching deployments); red 0..0 edges are turned off in this role. Node markers show the role’s deploy modes (💻 host, 🐳 compose, 🐝 swarm); ❌ marks a service that is explicitly turned off, and ⚙️ an Ansible role dependency declared in meta/main.yml.

Purpose

The Certbot role provides a ready-to-use, automated solution for SSL/TLS management in your infrastructure. Whether you’re managing traditional servers or containerized environments, this role ensures your certificates are always in place and valid.

Features

• Certbot Installation: Ensures the latest version of Certbot is installed.

• DNS Plugin Installation: Installs a matching plugin based on your configured ACME challenge method.

• Credential Directory Management: Creates a secured /etc/certbot directory with proper permissions.

• API Token File Setup: Manages API token files securely for DNS challenge authentication.
