MDMDirector

MDMDirector is an opinionated orchestrator for MicroMDM. It enables profiles to be managed with MicroMDM in a stateful manner, via a RESTful API. It also allows for installation of packages either just at enrollment or immediately. It receives webhook events from MicroMDM and then instructs MicroMDM to perform appropriate actions. As such, MDMDirector does not need to be exposed to the public internet.

Usage

MDMDirector is a compiled binary and is configured using flags.

Requirements:

  • Redis for the scheduled checkin queue
  • PostgreSQL database for storing device information
  • (Recommended) Signing certificate for signing profiles
  • (STRONGLY recommended) Load balancer/proxy to serve and terminate TLS for MDMDirector

MicroMDM Setup

You must set the -command-webhook-url flag on MicroMDM to the URL of your MDMDirector instance (with the addition of /webhook).

-command-webhook-url=https://mdmdirector.company.com/webhook
