RCOSd

RCOSd is the daemon component of the RCOS project, a distributed system designed to orchestrate remote command execution and workflow management across compute resources. Operating as a background service on server nodes, RCOSd accepts requests from RCOS clients or agents, authenticates them, and coordinates the execution and monitoring of tasks. The design emphasizes reliability, security, and auditable operation, with state persisted to a backend store and operations exposed through a defined protocol.

Key capabilities include secure transport with TLS and optional mutual authentication, role-based access control for command permissions, and detailed audit logging. RCOSd can schedule and queue jobs, manage task dependencies, retry failed steps, and provide retry policies and timeouts. It supports sandboxed or restricted execution environments, outputs capture, and centralized logging and metrics collection. The component uses a modular architecture with pluggable backends for storage, transport, and authentication, enabling deployment in data centers, cloud, or edge environments. It also supports high availability through clustering and configuration-driven failover and can be managed via common service frameworks on supported platforms.

In typical deployments, RCOSd runs as a system service and is integrated with other RCOS components, including clients and agents, to form a complete orchestration stack. The software is designed to be configurable and extensible, with community and vendor contributions to its plugins and protocols. RCOSd aims to provide a scalable, auditable foundation for automated remote execution in complex environments.
