About:
Dnsrobocert automates the issuance and renewal of Let's Encrypt SSL certificates using DNS challenges. It is designed for environments where web server ports are unavailable or for securing wildcard domains. The tool integrates with various DNS providers to manage TXT records required for domain validation.

Key Features:

Automated certificate issuance and renewal via Let's Encrypt
Support for a wide range of DNS providers for ACME DNS-01 challenges
Configuration-driven via a simple YAML file
Support for wildcard certificates
Docker-ready for containerized deployments

Use Cases:

Securing internal services or APIs not exposed to the public internet
Issuing wildcard SSL certificates for multiple subdomains
Automating certificate management in CI/CD pipelines

Alternatives:

Certbot – Certbot is the official EFF client, typically using HTTP-01 challenges. Dnsrobocert specializes in DNS-01 challenges, making it better for internal services and wildcards.
acme.sh – A lightweight POSIX-compliant shell script client. Dnsrobocert offers a Python-based, container-friendly approach with declarative YAML configuration.
