Armadillo – A DNS Server in Gleam for Homelab Use

Description and use

**Brief Summary (2‑3 sentences)**
Armadillo is an open‑source DNS server written in Gleam, aimed at homelab environments where teams want to reuse common service‑infrastructure components instead of building their own DNS layer from scratch. It offers a lightweight, type‑safe alternative for quickly standing up internal DNS while encouraging standardized service patterns across API deployments. Because integration signals are sparse, a manual review of the repository, licensing, and documentation is recommended before adoption.

**Value**

• **Reusable infrastructure** – Provides a ready‑made DNS service that can be shared across multiple microservices, reducing duplicated effort and accelerating API rollout.
• **Type safety & concurrency** – Gleam’s strong static typing and Erlang‑VM concurrency model give you reliable, low‑latency DNS handling with fewer runtime bugs.
• **Homelab‑friendly** – Minimal dependencies and a small footprint make it ideal for development, testing, and internal staging clusters.

**Practical Adoption Path**

1. **Evaluate the repo** – Clone the project, review the LICENSE, read the README, and run the test suite to confirm it builds on your Gleam/Erlang version.
2. **Prototype** – Deploy Armadillo in a sandbox (e.g., a Docker container or a local VM) and point a few internal services to it; verify resolution, logging, and any custom record handling you need.
3. **Integrate** – Add the server to your infrastructure‑as‑code pipeline (Terraform, Ansible, etc.), configure it to read zone data from your source of truth (e.g., Consul, etcd, or static files), and update your service discovery scripts to use the new DNS endpoint.
4. **Validate** – Run integration tests that simulate service failures, DNS cache behavior, and scaling scenarios; address any gaps in documentation or missing features.

**Production Readiness**

• **Maturity**: Rated “Medium.” The codebase is recent (last updated 2026‑06‑28) but shows limited community signals (few topics, sparse integration metadata).
• **Suitability**: Good for prototypes, internal tools, or homelab‑level workloads where the risk of occasional downtime is acceptable.
• **Due Diligence**: Before moving to production, verify the project’s license, check the issue tracker for unresolved bugs, confirm a regular release cadence, and ensure you have a plan for long‑term maintenance (e.g., forking or contributing fixes).

In short, Armadillo can speed up internal DNS provisioning for Gleam‑centric stacks, but it should be piloted and thoroughly vetted before being trusted in a production environment.

Use in a workflow
