What is Rundeck CE?

Rundeck CE is an open-source software that enables DevOps teams to automate and manage their infrastructure and applications. It allows users to create, execute, and manage workflows, known as jobs, which can be composed of a sequence of tasks, such as shell commands, scripts, and API calls. Rundeck CE provides a web-based interface for users to define, schedule, and monitor jobs, as well as a robust API for integrating with other tools and systems.
