A simple container orchestrator with declarative service deployment using containers.
Ring was created as a lightweight alternative to Kubernetes and Docker Swarm, providing only the essential features needed for container orchestration.
- Declarative Deployments: Specify your service requirements through configuration files
- Smart State Management: Automatically compute differences between desired and current state (similar to Terraform)
- High Availability: Automatic container restart and replication
- RESTful HTTP API: Easy integration with your existing tools
- Docker Engine Backend: Leveraging proven Docker technology
Note: Ring does not handle load balancing, as it's not within its scope.
