Tag anatomy

  • Tags: Short descriptors for machines, VM hosts, controllers, storage, and network interfaces.
  • Annotations: Detailed, static or dynamic descriptions.
  • Scripts: Tags can group scripts for commissioning/testing.

Automatic tags

Automatic tagging is available in MAAS v3.2+.

Define machine criteria via XPath expressions. Tags apply automatically based on:

  • Hardware features (mapped from lshw XML output).
  • Node capabilities (CPU, network speed, etc.).
  • Kernel options, combined alphabetically at boot.
