9.12. Digital Rebar Directory Structure¶
A complete Digital Rebar installation consists of a core component, and optional workloads (such as kubernetes, ceph, hardware).
The workloads each have their own GIT repository. The Digital Rebar core repository is the essential engine that drives Digital Rebar and can operate alone from any of the workload components. The workload components of Digital Rebar have built-in dependencies on the core. Workloads are not required to be part of the Digital Rebar project to run on the framework.
