Define a reusable group of machines based on labels and conditions for automated cluster allocation.

This guide shows you how to create a machine class.

Create a file called machine-class.yaml with the following content:

metadata:
  namespace: default
  type: MachineClasses.omni.sidero.dev
  id: test
spec:
  matchlabels:
    # matches machines with amd64 architecture and more than 2 CPUs
    - omni.sidero.dev/arch = amd64, omni.sidero.dev/cpus > 2

Create the machine class:

omnictl apply -f machine-class.yaml

UI

Next, click the “Create Machine Class” button on the right.

Add machine query conditions by typing them manually in the input box.

Clicking the label in the machine list will add them to the input box.
