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".

Cozystack
Cozystack is a free and open-source platform and framework for building clouds.
Cozystack is a CNCF Sandbox project that was originally built and sponsored by Ænix.
With Cozystack, you can transform a bunch of servers into an intelligent system with a simple REST API for spawning Kubernetes clusters, Database-as-a-Service, virtual machines, load balancers, HTTP caching services, and other services with ease.
Use Cozystack to build your own cloud or provide a cost-effective development environment.
Use-Cases
-
Using Cozystack to build a public cloud
You can use Cozystack as a backend for a public cloud -
Using Cozystack to build a private cloud
You can use Cozystack as a platform to build a private cloud powered by Infrastructure-as-Code approach -
Using Cozystack as a Kubernetes distribution
You can use Cozystack as a Kubernetes distribution for Bare Metal
