cozy-lib.resources.sanitize divides the CPU limit by cpuAllocationRatio
and rendered the quotient as a bare float. When the ratio does not
divide the value evenly the result is finer than a milli-CPU, and the
VPA admission webhook rejects it outright:
admission webhook "vpa.k8s.io" denied the request:
minAllowed: CPU [62500u] must be a whole number of milli CPUs
packages/extra/etcd routes its VPA minAllowed/maxAllowed through the
helper, so 250m / 4 = 62.5m left the etcd HelmRelease looping
UpgradeFailed -> RollbackFailed forever: the rollback target renders the
same invalid value. Since v1.6.0 HelmReleases wait on each other, so
that one stuck app also blocks tenant-root, cozystack-basics and
kubevirt-cdi-operator, and without CDI the Talos worker rollover cannot
import the worker OS image. Only the divisors of 250 worked as ratios,
which is an artefact of one chart's hardcoded floor rather than a real
constraint on the operator.
The request is rounded up, never down, so it stays at or above the
intended fraction of the limit. It is rounded only when it has to be:
if the milli-CPU value equals its own ceiling, the float keeps its
current rendering, so nothing changes on the default ratio of 10 or on
any ratio that divides evenly; otherwise it renders as the ceiling in
m. The comparison is exact, with no tolerance. sprig's divf and mulf run
on shopspring/decimal rather than float64, so mulf (divf 0.25 10.0)
1000.0 renders exactly 25 and there is no binary-float noise on this
codepath to absorb. A tolerance would reintroduce the bug: a value
whole-milli only to within it, such as 100.0000004m at ratio 1, would
read as exact and render "0.1000000004", rejected for the same reason
62.5m is. The same predicate covers sub-milli input, since ceil carries
any positive request to at least 1m, and a zero request stays "0".
