ProvisionerSpec is the top level provisioner specification. Provisioners launch nodes in response to pods where status.conditions[type=unschedulable, status=true]. Node configuration is driven by through a combination of provisioner specification (defaults) and pod scheduling constraints (overrides). A single provisioner is capable of managing highly diverse capacity within a single cluster and in most cases, only one should be necessary. It's possible to define multiple provisioners. These provisioners may have different defaults and can be specifically targeted by pods using pod.spec.nodeSelector["karpenter.sh/provisioner-name"]=$PROVISIONER_NAME.

func (Requirements) Consolidate

func (r Requirements) Consolidate() (requirements Requirements)

Consolidate combines In and NotIn requirements for each unique key, producing an equivalent minimal representation of the requirements. This is useful as requirements may be appended from a variety of sources and then consolidated. Caution: If a key has contains a `NotIn` operator without a corresponding `In` operator, the requirement will permanently be [] after consolidation. To avoid this, include the broadest `In` requirements before consolidating.
