A complete OpenCrowbar installation consists of a core component, and workloads (such as openstack, hadoop, hardware). The base installation directory in a production environment will consist of:
| Directory | Description | Role |
|---|---|---|
| /opt/opencrowbar/core | Core OpenCrowbar Complete system foundation and WebUI | Mandatory |
| /opt/opencrowbar/hadoop | Hadoop workload components | Optional |
| /opt/opencrowbar/hardware | RAID and BIOS Hardware Provisioner workload components | Optional |
| /opt/opencrowbar/openstack | OpenStack workload components | Optional |
| /opt/opencrowbar/ceph | Ceph worload components | Optional |
The above components each have their own GIT repository. The OpenCrowbar core repository is the essential, engineer that drives OpenCrowbar and can operate alone from any of the workload components. The workload components of OpenCrowbar have built-in dependencies on the core.
The directory structure of the core consists of these parts under the /opt/opencrowbar/core directory:
| Sub-Directory | Description of Contents |
