mgmt

Mgmt is a distributed, event-driven configuration management tool written in Go that enables real-time automation across clusters of machines. It uses a custom language (mcl) to define configurations that automatically adjust based on live system state and can coordinate resources across multiple hosts without manual intervention.

What mgmt is

Mgmt is a real-time, decentralized automation engine built on graph theory and event-driven architecture, supporting closed-loop feedback systems and dynamic scheduling across distributed clusters. It provides a resource model, function library, and scheduling primitives (e.g., round-robin max scheduling) via mcl, a domain-specific language, and integrates with etcd for cluster coordination.

Quickstart

Get the mgmt source

Clone the repository and explore it locally.

terminalbash
git clone https://github.com/purpleidea/mgmt.gitcd mgmt# follow the project's README for install & configuration

Best use cases

Real-time Distributed Orchestration

Coordinate resource placement and state across multiple hosts in real-time, e.g., ensure a service runs on exactly N nodes as the cluster membership changes dynamically.

Event-Driven Infrastructure Automation

Build closed-loop feedback systems that react instantly to state changes (e.g., adjust file permissions when day-of-week changes, scale services based on live metrics).

Decentralized Configuration Management

Run as a cluster of autonomous agents that synchronize state continuously without a central controller, reducing single points of failure and improving responsiveness.

Implementation considerations

  • Requires learning mcl language and mgmt's resource/function model; budget time for team ramp-up beyond typical config management tools.
  • Cluster setup requires etcd for distributed coordination; plan infrastructure to support etcd quorum and network topology requirements.
  • Real-time mode runs continuously and exchanges state; design network monitoring and logging to observe agent health and cluster consensus.
  • Testing configurations in isolated environments recommended before production; closed-loop behavior can amplify misconfigurations at scale.
  • Decentralized architecture means debugging cross-node issues requires familiarity with distributed systems concepts and log aggregation.

When to avoid it — and what to weigh

  • Need Instant Enterprise Support — Project is community-driven with optional enterprise services via m9rx.com; no SLA or guaranteed response times documented in public repos.
  • Heavy Reliance on Existing Tool Ecosystem — Mgmt uses its own mcl language and architecture; integrations with Puppet, Ansible, Chef, etc. are not built-in and require custom development.
  • GPL-3.0 License Incompatible with Your Codebase — GPL-3.0 is copyleft; any proprietary or differently-licensed code linking mgmt must ensure compatibility or seek separate licensing.
  • Conservative, Proven-Stable-Only Deployments — Project is 10+ years old but latest release (1.1.0) is from June 2026; production adoption is growing but not yet mainstream in large enterprises.

License & commercial use

GNU General Public License v3.0 (GPL-3.0). This is a copyleft license requiring that any derivative works or works that link/embed mgmt must also be licensed under GPL-3.0 or compatible. Source code must be provided.

GPL-3.0 is not a permissive license. Commercial use of mgmt itself is permitted, but any modifications or proprietary integrations must be licensed under GPL-3.0 or comply with copyleft obligations. Enterprise services and support are available via m9rx.com; review their offerings and licensing terms separately. Do not assume commercial use freedom without legal review.

Security considerations

No explicit security audit or threat model stated in README or provided data. Considerations: etcd cluster must be secured (RBAC, encryption, network isolation); mgmt agents run with elevated privileges to manage system state; mcl language design for injection/escape vectors requires code review; audit logging and access control mechanisms should be validated before production use. Consult official security documentation and conduct threat modeling for your environment.

Alternatives to consider

Ansible

Simpler learning curve, larger ecosystem, agent-optional. Lacks real-time closed-loop feedback and decentralized orchestration model; pull-based architecture differs significantly.

Puppet

Mature, strong ecosystem, good for large-scale infra. More centralized control model; migration path exists but Puppet DSL and resource model differ from mgmt's mcl and graph-based approach.

Kubernetes + Operators

If containerized workloads and Kubernetes-native orchestration fit your use case. Focuses on container orchestration, not bare-metal or non-Kubernetes infrastructure automation.

mgmt FAQ

Can I run mgmt on a single node or do I need a cluster?
Single-node deployments are supported; however, mgmt's value proposition centers on real-time, decentralized multi-node clusters. Single-node mode is suitable for learning and simple use cases.
How does mgmt differ from Puppet or Ansible?
Mgmt is event-driven and real-time with closed-loop feedback; Puppet and Ansible are declarative pull/push models. Mgmt runs continuously and responds to state changes instantly; they typically run on schedules. Mgmt's distributed architecture allows autonomous agents to coordinate without central control.
What are the compute/network requirements for a mgmt cluster?
Unknown; not clearly stated in provided data. Consult official performance tuning and deployment guides. Network latency between agents and etcd, plus agent CPU/memory for state management, should be evaluated for your scale.
Can I migrate from Puppet to mgmt?
A Puppet migration guide is documented. Direct translation is not automatic; you will need to rewrite configurations in mcl. Community and m9rx support may assist.
