Rundeck is a command orchestration and process automation tool. It allows users to execute commands and scripts on nodes dynamically added and removed from its resource model. It provides a web UI, REST API, and CLI for command orchestration and automation. Projects in Rundeck define nodes, jobs, and filters to target nodes using metadata rather than just hostnames. Installation and configuration of Rundeck on RHEL is also covered.
