AutoTLS — Roadmap

  • Last updated: 2025‑08‑25
  • Maintainers: SRE team (primary: Barbara Shaurette)

Vision

A lightweight, production‑tested tool that automates TLS certificate issuance, rotation, and distribution, with pluggable providers for DNS challenges and secrets storage.

Principles

  • Safety first: idempotent operations, test modes, and clear rollback
  • Sharp edges wrapped: sane defaults, explicit switches for impactful changes
  • Pluggability over hardcoding: providers as modules
  • Observability: structured logs; hooks for metrics
  • Docs as a feature: example snippets included

Current Snapshot (2025‑08‑21)

  • Packaging: pyproject.toml with requires-python = ">=3.9".
  • Tooling: pytest, pytest-cov, ruff; GitHub Actions present for testing.
  • App structure: Flask application factory pattern in progress; internal version stable.
  • ACME: Let’s Encrypt via acme library; AWS Route 53 for DNS‑01; AWS Secrets Manager for storage; Fastly API integration in internal build.

Roadmap / Future Features

Core priorities (short-term)

  • Additional DNS plugins: Support for providers beyond AWS Route 53.

    • Cloudflare
    • Google Cloud DNS
    • GoDaddy
  • Additional secrets backends:

    • Hashicorp Vault
    • GCP Secret Manager
    • local filesystem
  • Write a database initialization helper that is database agnostic and leverages the existing models

  • Replace deprecated pyOpenSSL calls with cryptography (include any tests that touch functionality that uses pyOpenSSL)

  • Fastly integration enhancements: Integrate utility scripts for clearing expired keys and listing current certificates.

  • Write troubleshooting docs (ACME, DNS propagation, Fastly deploys).

  • Improve error handling consistency (decide on returns vs. exceptions vs. unified result objects, and Slack notifier integration)

  • Improve test coverage (including new tests for the secrets and DNS backends)


Advanced features (medium-term)

  • Notifications plugin to provide alternatives to Slack

  • Add a dry‑run alternative to testmode (primarily to validate the Fastly step without uploading)


Stretch goals / nice-to-haves (long-term)

  • Multi-account DNS management: Cross-account/organization DNS automation, including minimal‑privilege IAM examples for AWS

  • Pluggable certificate authorities: Support for alternatives to Let’s Encrypt (e.g., ZeroSSL) behind common ACME interface.

  • Config & CLI polish: More robust CLI options, YAML config validation, and helpful error messages.
