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.

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
