Continuous And Never-ending Inventory

Use Cases

  • Migrating from one inventory system to another
  • Validating exisiting inventory data
  • Exporting to another inventory format
  • Serving as a front-end for the UX, while the backend is replaced with something new
  • Use as a new self-contained inventory system

Add/Remove/Update Hardware Example

cani session init csm # start a session with a specific provider by importing data and converting it to CANI format
cani add cabinet hpe-ex4000 --auto --accept # add hardware (child hardware is added automatically: chassis, controllers, etc.)
cani add blade hpe-crayex-ex4252-compute-blade --auto --accept # add a blade to the cabinet (and any nodes that hardware contains)
cani update node --uuid abcdef12-3456-2789-abcd-ef1234567890 --role Management --subrole Worker --nid 4 # update hardware metadata
cani export --format hpcm # export to another inventory format (can also commit and init a new session with a different provider)
cani session apply --commit # apply changes, retaining the CANI format, and optionally posting data to the provider

Portable Inventory Format

cani uses a simple key/value approach where each piece of hardware as a unique identifier. Any metadata or relationships to other hardware components is self-contained to that entry in the datastore.
