Enum TaintEffect 

Source 
pub enum TaintEffect {
    Repels(LifecycleArchetype),
    Attracts,
    Inert,
}
Expand description

How a key in MachineConfig::taints can affect placement.

W305 finding 1: before R742-T4 nothing asked this question, so a key that no scheduler path could read — "qa", "no-voter" — parsed, validated, and quietly did nothing. Both of the findings that cost real fleet state were invisible for exactly that reason.

Variants§

§

Repels(LifecycleArchetype)

"no-<archetype>": rejects workloads of that archetype outright. Read by RequiredSpec::matches via repel_archetype.

§

Attracts

A key in AFFINITY_TAINT_KEYS: a workload naming it in yah.placement.requires-taint is restricted to nodes carrying it.

§

Inert

Neither. No placement decision can read this key.
