NanoMDM

NanoMDM is a minimalist Apple MDM server and library heavily inspired by MicroMDM.

Getting started & Documentation

• Quickstart
  A quick guide to get NanoMDM up and running using ngrok.

• Operations Guide
  A brief overview of the various command-line switches and HTTP endpoints and APIs available to NanoMDM.

Getting the latest version

• Release .zip files containing the server and supplementals should be attached to every GitHub release.
  • Release zips are also published for every main branch commit.
• A Docker container is built and published to the GHCR.io registry for every release.
  • docker pull ghcr.io/micromdm/nanomdm:latest — docker run ghcr.io/micromdm/nanomdm:latest
  • A Docker container is also published for every main branch commit (and tagged with :main)
• If you have a Go toolchain installed you can checkout the source and simply run make.

Features

• Horizontal scaling: zero/minimal local state. Persistence in storage layers. MySQL and PostgreSQL backends provided in the box.
• Multiple APNs topics: potentially multi-tenant.
• Multi-command targeting: send the same command (or pushes) to multiple enrollments without individually queuing commands.
• Migration endpoint: allow migrating MDM enrollments between storage backends or (supported) MDM servers
• Otherwise we share many features between MicroMDM and NanoMDM, such as:
  • A MicroMDM-emulating HTTP webhook/callback.
  • Enrollment-certificate authorization
  • API-driven interaction (queuing of commands, APNs pushes, etc.)

$x not included

NanoMDM is but one component for a functioning MDM server. At a minimum you need a SCEP server and TLS termination, for example. If you've used MicroMDM before you might be interested to know what NanoMDM does not include, by way of comparison.

• SCEP.
  • Spin up your own scep server. Or bring your own.
• TLS.
  • You'll need to provide your own reverse proxy/load balancer that terminates TLS.
• ADE (DEP) API access.
  • While ADE/DEP enrollments are supported there is no DEP API access.
• Enrollment (Profiles).
  • You'll need to create and serve your own enrollment profiles to devices.
• Blueprints.
  • No 'automatic' command sending upon enrollment. Entirely driven by webhook or other integrations.
• JSON command API.
  • Commands are submitted in raw Plist form only. See the cmdr.py tool that helps generate raw commands
  • The micro2nano project provides an API translation server between MicroMDM's JSON command API and NanoMDM's raw Plist API.
• VPP.
• Enrollment (device) APIs.
  • No ability, yet, to inspect enrollment details or state.
  • This is partly mitigated by the fact that both the file and mysql storage backends are "easy" to inspect and query.

Architecture Overview

NanoMDM, at its core, is a thin composable layer between HTTP handlers and a set of storage abstractions.

• The "front-end" is a set of standard Golang HTTP handlers that handle MDM and API requests. The core MDM handlers adapt the requests to the service layer. These handlers exist in the http package.
• The service layer is a composable interface for processing and handling MDM requests. The main NanoMDM service dispatches to the storage layer. These services exist under the service package.
• The storage layer is a set of interfaces and implementations that store & retrieve MDM enrollment and command data. These exist under the storage package.

You can read more about the architecture in the blog post Introducing NanoMDM.
