Ring
A lightweight workload orchestrator with declarative deployments — single binary, no control plane.
Why Ring?
Ring is an alternative to Kubernetes and Docker Swarm that ships only the essentials: a REST API, a scheduler, and a state engine that reconciles desired vs. current state. No etcd, no operators, no helm charts.
Features
Declarative YAML/JSON deployments with state diffing
Replicas, rolling updates, and automatic restarts
Health checks (TCP, HTTP, command) with self-healing
Secrets, volumes, labels, resource limits (CPU/memory)
Multi-namespace isolation and network segmentation
User management with role-based access
Docker and Cloud Hypervisor runtimes
Ring does not handle load balancing — pair it with Traefik, Caddy, or nginx.
Quick start
cargo build --release
ring init<br>ring server start<br>ring login --username admin --password changeme<br>ring apply -f examples/nginx.yaml
See Installation for prerequisites and Your first deployment for a full walkthrough.
Documentation
Getting started — install, first deployment, managing deployments
Guides — health checks, rolling updates, secrets, networking, jobs
Reference — manifest schema, CLI commands, HTTP API
Runtimes — Docker, Cloud Hypervisor
