fix(multus): drop the CPU limit and make resources configurable by lexfrei · Pull Request #4830 · cozystack/cozystack

What this PR does

The multus daemon was too small to recover a node after a CNI outage, and its limits could not be raised from values. The 100m CPU limit and the 1Gi memory limit of kube-multus were hardcoded in the patched upstream template.

On a node with about 600 dead sandboxes and 220 pods waiting, multus was throttled in every CFS period. Its calls took longer than kubelet's two-minute CRI deadline, so every call was retried and the queue only grew. With the CPU limit lifted it OOM-looped at 1Gi. With 2 CPU and 4Gi it cleared the backlog in about three minutes.

Now the resources come from a new resources value. The default keeps the same requests (100m CPU, 100Mi memory), has no CPU limit, and raises the memory limit to 4Gi. The memory limit stays on purpose. Without it the pod cgroup has no memory.max, and multus becomes a candidate for the Talos userspace OOM handler again.

The chart now refuses to render when an override removes the memory limit or the memory request. Without a request Kubernetes uses the limit as the request, so a node with less allocatable memory than the limit would be left without multus.

The change is in patches/customize-deployment.patch, so make update keeps it. I applied the patch to upstream v4.3.0 and got the committed template, except the image references. The platform reverts a direct edit of the child cozystack.multus Package, so a running cluster sets the value through the new networking.multus.resources key of the platform Package. The key is passed on only when set, and a value that is not a map stops the render. The system-defaults LimitRange in the namespace sets memory only, so it does not bring a CPU limit back.

Closes #4829

The diff adds a platform value, so the hand-written key table on the website needs it. The follow-up PR there is a draft until this one merges.

Release note

fix(multus): the kube-multus container no longer has a CPU limit, and its memory limit is raised from 1Gi to 4Gi, so a node with hundreds of pods can recover after a CNI outage. Its resources can be overridden through the new `networking.multus.resources` platform value. An override that removes the memory limit or the memory request now fails the render.

Summary by CodeRabbit

New Features
- Added optional CNI plugin staging during Multus startup, configurable through chart values. Staging skips when the plugin directory is unavailable and reports individual copy failures while continuing.
- Made Multus resource settings configurable, with defaults of 100m CPU and 100Mi memory requests and a 4Gi memory limit. Rendering requires memory requests and limits.
- Updated the Multus deployment to use the cozy-multus namespace and DaemonSet name, and Cilium as the master CNI configuration.
Bug Fixes
- Added a 128Mi memory limit to the CNI installation step.

📝 Walkthrough

Walkthrough

The Multus package now accepts configurable daemon resources and supports optional CNI plugin staging. Platform bundles pass resource overrides to the package.

Changes

Multus deployment

Layer / File(s)	Summary
Pass resource overrides through platform bundles `packages/core/platform/templates/_helpers.tpl`, `packages/core/platform/templates/bundles/system.yaml`, `packages/core/platform/values.yaml`, `packages/core/platform/tests/bundles_multus_resources_test.yaml`	A platform helper validates and passes optional Multus resource overrides. Talos and generic Linux bundles use the helper. Tests cover overrides, unset and null values, and invalid types.
Configure Multus daemon resources `packages/system/multus/values.yaml`, `packages/system/multus/templates/multus-daemonset-thick.yml`, `packages/system/multus/patches/customize-deployment.patch`, `packages/system/multus/tests/multus_test.yaml`	The package defaults to `100m` CPU and `100Mi` memory requests, with a `4Gi` memory limit. The DaemonSet renders configured resources and fails if either memory value is missing or resource values have invalid types. Tests cover defaults, overrides, and invalid values.
Stage CNI plugins `packages/system/multus/patches/customize-deployment.patch`	When `stageCniPlugins` is enabled, an init container attempts to copy plugins from `/cni-plugins` to the host CNI binary directory. It skips a missing source directory and reports individual failures while continuing.

Verdict

NOT LGTM (request-changes)

Most of this is solid. resources becomes {{- toYaml .Values.resources | nindent 12 }}, the patch and the committed template carry the same block, helm unittest passes 14/14, and dropping the CPU limit is the right call for a CNI that every pod sandbox waits on. The blocker is narrower. The memory limit is the one thing this PR treats as a safety invariant, the comment and values.yaml both say so, and a config override can still remove it silently. The stageCniPlugins key one file over already refuses to render a bad value, so the chart holds that bar elsewhere.

Findings

[MAJOR] packages/system/multus/templates/multus-daemonset-thick.yml:182, the "keep a memory limit" invariant is documented but not enforced at render

[MINOR] packages/system/multus/values.yaml:20, resources.requests: null reserves the 4Gi limit on every node

[NIT] packages/system/multus/tests/multus_test.yaml:61, the overridable test covers only the additive direction

Caveats

Value-domain of .Values.resources was rendered across the whole domain. Deep-merge keeps the 4Gi memory limit for every accidental path; only a deliberate null drops it. A non-object value (string/list) renders YAML the apiserver rejects at apply, which is loud and less concerning.
Default render is QoS Burstable, 4Gi memory limit, no CPU limit. Upgrade N-1 to N is a one-node-at-a-time multus rolling restart (expected). QoS stays Burstable; limits.cpu was chart-owned so SSA removes it cleanly. The live Flux/SSA apply was not run (hermetic boundary).
Live CI on 86bba343 is fully green, including "Unit & controller tests" and "E2E (in-tree)". Merging current origin/main onto the head and running helm unittest plus the multus and main-changed bats stayed green; main touches nothing in this chart.

IvanHunters · 2026-10-10T17:25:05Z

-            limits:
-              cpu: "100m"
-              memory: "1Gi"
+            {{- toYaml .Values.resources | nindent 12 }}


[MAJOR] the "keep a memory limit" invariant is documented but not enforced at render

values.yaml:16 states "Keep a memory limit whatever its size" and the comment above resources explains why: with no memory.max on the pod cgroup the Talos userspace OOM handler (v1.12+) makes multus an eviction candidate on every node, which is the exact failure this change exists to prevent. Nothing enforces that invariant.

Helm deep-merge protects the accidental paths ({}, a partial --set resources.limits.cpu=2, --set resources.requests.cpu=200m all keep the 4Gi limit, verified by render). But a deliberate null, which an operator can write through the documented spec.components.multus.values.resources override, reaches the dangerous state silently:

$ helm template r packages/system/multus --set resources.limits.memory=null --set resources.limits.cpu=2 resources: limits: cpu: 2 requests: cpu: 100m memory: 100Mi

A CPU limit is back and the memory limit is gone; resources: null and resources.limits: null drop it the same way (rendered). All 14 unittests stay green, so the suite pins only the default render. Before this PR the limit was hardcoded and could not be dropped at all, so making the block configurable opens a safety surface that did not exist.

This chart already sets the bar for exactly this class of value: stageCniPlugins is validated at render with {{- fail }} (template:244) and has a failedTemplate test plus a null test (tests/multus_test.yaml:134). Mirror it for the memory limit, e.g.

{{- if not (kindIs "map" .Values.resources) }}{{- fail (printf "resources: expected a map, got %s" (kindOf .Values.resources)) }}{{- end }} {{- if not (dig "limits" "memory" "" .Values.resources) }}{{- fail "resources.limits.memory must be set, see the comment above" }}{{- end }}

and add a failedTemplate test for resources.limits.memory: null modeled on the stageCniPlugins one. What would change my mind: a namespace LimitRange that reliably stamps a memory limit regardless (the PR body claims one; grep -rn LimitRange found none in-tree).

The chart now refuses to render without a memory limit, fixed in 7d3d60c. The LimitRange exists, but the operator creates it in Go, so a grep over YAML can't find it. It only sets a default memory limit and request, and it is best effort: reconcile errors are just logged, and --system-namespace-memory-limit=0 turns it off. The chart can also be installed without the operator. So I kept the guard.

+## templates/multus-daemonset-thick.yml explains why.
+##
+resources:
+  requests:


[MINOR] resources.requests: null reserves the 4Gi limit on every node

With resources.requests: null the block renders with only limits: {memory: 4Gi} (verified by render). Kubernetes defaults an absent request to the limit, so every DaemonSet pod then requests 4Gi of memory on every node. On a node whose allocatable memory is below 4Gi the multus pod stays Pending and that node has no CNI. This is admin-reachable, not an accidental path, hence MINOR; a dig "requests" "memory" check would cover it if you add the guard above, but it widens the chart's responsibility so it is your call.

I went with a guard here too. A default that survives null would override a value the admin set on purpose, while a failed render says what is missing. requests.cpu stays optional: without it the pod still schedules, just with fewer CPU shares.

+      - notExists:
+          path: spec.template.spec.containers[?(@.name=="kube-multus")].resources.limits.cpu
+
+  - it: kube-multus resources are overridable from values


[NIT] the overridable test covers only the additive direction

The new resources are overridable from values test adds limits.cpu and raises limits.memory; there is no test for the subtractive direction (null) or a wrong type. Without the guard from the MAJOR there is nothing to assert against, so this folds into that fix; listed separately so it is not lost. A failedTemplate case on resources.limits.memory: null closes both.

Covered by the new failure tests for both guards.

IvanHunters fixed in 7d3d60c, replies are in the threads. The patch still applies cleanly on upstream v4.3.0. Ready for another look.

kube-multus serves the CNI call for every pod sandbox on its node, and its 100m CPU limit was hardcoded in the patched upstream template. After a CNI outage a node had ~600 dead sandboxes and 220 pods waiting: multus was throttled in every CFS period, calls outlived kubelet's two-minute CRI deadline, each retry grew the queue, and the node never recovered. With the CPU limit lifted the 1Gi memory limit OOM-looped; 2 CPU and 4Gi cleared the backlog in about three minutes. Resources now come from values, defaulting to the same requests, no CPU limit and a 4Gi memory limit. The memory limit stays so the pod cgroup keeps memory.max and remains outside the Talos OOM handler's candidate set. Since an explicit null in a values override could drop either memory key, the render now fails without limits.memory or requests.memory. Without the request it defaults to the limit, and a node with less allocatable memory than that is left without multus. Assisted-by: LLM Signed-off-by: Aleksei Sviridkin <[email protected]>

The multus chart takes its resources from values, but the platform renders the cozystack.multus Package with stageCniPlugins alone, and an edit to that child Package is reverted by the platform reconcile. A running cluster therefore had no way to raise the multus limits. networking.multus.resources is passed to the Package only when set, so an unset key leaves the chart default in charge. A value that is not a map stops the render here; the multus chart keeps refusing a render without a memory limit or request. Assisted-by: LLM Signed-off-by: Aleksei Sviridkin <[email protected]>

IvanHunters I widened the PR a bit since your review. The platform reverts edits to the child multus Package, so a running cluster had no way to use the new value. It is now set through networking.multus.resources on the platform Package and passed to multus only when set. A limits or requests that is not a map now fails the render with a named error too. The website table follow-up is cozystack/website#747.

Verdict

LGTM

All three findings from my earlier round are closed, and I checked each one by rendering it. resources.limits.memory and resources.requests.memory are enforced at render time now, so neither the documented override nor an explicit null drops the memory limit without failing the render: helm template exits non-zero with the named error on every path I tried, and the new failedTemplate tests cover the null, cleared, and wrong-type cases. The default render is a 4Gi memory limit, a 100Mi request, and no CPU limit, and QoS stays Burstable. The guard sits in the terminal chart, so the platform override path is covered too: an explicit null survives the helper round-trip and still fails the child render. Both chart unittests pass, the multus and platform bats suites pass, and CI on the head is green.

The four notes below are hardening, not blockers. None is a regression and none changes the verdict.

Findings

[MINOR] packages/system/multus/templates/multus-daemonset-thick.yml:184, a zero-quantity memory limit passes the guard

[MINOR] packages/core/platform/templates/_helpers.tpl:180, the platform helper validates only that resources is a map

[NIT] packages/system/multus/templates/multus-daemonset-thick.yml:184, empty-map memory limit fails with a misleading message

[NIT] packages/core/platform/templates/_helpers.tpl:164, comment says resources is passed only when set

Checked and correct

Prior blockers, all closed: the memory-limit guard, the memory-request guard, and the subtractive and wrong-type test coverage. I also re-checked the default render, the partial-override deep-merge, the explicit-null platform path, and every bundle variant that ships multus.

[MINOR] a zero-quantity memory limit passes the guard

dig "limits" "memory" "" .Values.resources tests truthiness, so null, "", 0 (int) and false fail loudly as intended. But 0Gi, 0Mi and "0" are non-empty strings and pass the guard: helm template r packages/system/multus --set resources.limits.memory=0Gi renders the kube-multus container with limits.memory: 0Gi and exits 0.

The kubelet forwards a zero memory limit to the runtime as no limit, so the pod cgroup ends up with no memory.max, the exact state this guard's message says it prevents, while the render reports success. It takes a deliberate 0Gi/0Mi/"0", and the operator can set a real value to recover, so this is a follow-up and not a blocker. Rejecting a zero numeric part on limits.memory closes it.

The render part is confirmed, 0Gi and "0" both render. The apply is louder than that, though. With the default 100Mi request the API server rejects the DaemonSet, because the request is above the limit. The pod runs without memory.max only when requests.memory is zero too, and the requests guard lets that through as well. Tracked in #4885 as rejecting a zero quantity on both keys.

[MINOR] the platform helper validates only that resources is a map

A mid-level type error such as networking.multus.resources.limits: 4Gi passes this check and renders a Package carrying limits: 4Gi. The platform HelmRelease then goes Ready and the failure surfaces one object away, in the child multus HelmRelease (resources.limits: expected a map, got string). Loud, but one hop late. The sibling stageCniPlugins path validates fully here at the platform.

Agreed. Tracked in #4885: the platform can run the same limits/requests map checks the multus chart does.

[NIT] empty-map memory limit fails with a misleading message

resources.limits.memory: {} fails with the "must be set" error although it is set: dig returns the empty map, which is falsy, so the render stops. The outcome is correct, but the wording misleads for a value that is present but empty.

Reproduced, limits.memory: {} stops with "must be set". Tracked in #4885 together with the zero-quantity case.

[NIT] comment says resources is passed only when set

An empty map resources: {} is still forwarded as resources: {} into the Package, even though the comment says resources is passed only when set. Harmless, since the chart deep-merge restores every default, but the comment is imprecise about the empty-map case.

{} is forwarded, and Helm keeps the defaults under it. Comment fix tracked in #4885.

follow-up: ### Release note ```release-note fix(backupstrategy-controller): the ClickHouse (Altinity) and RabbitMQ backup strategy Pods now run a dedicated `backup-http-client` image (alpine + curl + jq + ca-certificates, non-root, ~7 MB) instead of the 349 MB `platform-migrations` image. Air-gapped mirrors need the new `ghcr.io/cozystack/cozystack/backup-http-client` repository. fix(e2e): a chainsaw assert in the e2e suites keeps polling through a transient API error such as an etcd leader change, instead of failing the suite long before its timeout. fix(ci): use GITHUB_TOKEN to start the initial packages build when freezing a release line fix(etcd): the tenant etcd alert etcdHighNumberOfFailedGRPCRequests now counts only the gRPC codes that the etcd mixin and the platform copy of the alert count, so the Canceled watch streams of a Kubernetes API server that stops no longer fire it on every etcd member. fix(tcp-balancer): HAProxy now takes its fd and thread caps from the replica's memory and CPU limits instead of the node, so a t1.nano balancer is no longer OOMKilled on nodes with many CPUs. maxconn follows the memory limit at about 16 connections per MiB, 2035 on t1.nano, and the pods roll once on upgrade. fix(kubernetes): the Proxmox cloud-controller-manager now runs v0.16.1, and the Proxmox CCM and CSI driver images are pinned by digest. The v0.15.0 tag referenced before was re-pushed upstream to a build that panics on start, which left every new Proxmox worker with the uninitialized taint. fix(marketplace): a tapped repository is pinned to a digest instead of following a mutable tag, so moving the tag upstream no longer changes what runs in the cluster; connect accepts oci://...＠sha256:... and an optional keyless cosign verify policy (anchored to an exact identity and preserved across re-connects), and with verify flags the CLI verifies the signature and pins the verified digest at tap time. fix(dashboard): tenant name in the tenant list links to its detail page now (where Delete is), and top level tenants get their Edit button back. fix(cilium): the IPAM migration hook no longer fails with "Argument list too long" on clusters with more than a few nodes, which blocked the cilium upgrade and every package that depends on networking. fix(kubernetes): the OIDC bootstrap Job no longer fails to start for a tenant cluster with about 240 or more oidc.users, the bindings now come from a ConfigMap the Job mounts. fix(clickhouse): a RestoreJob now restores the archive its Backup was taken as, not the newest one. New Backups record the archive name, Backups taken before this release are restored best effort from the newest archive stamped no later than their takenAt, with a warning in the restore pod log. A ClickHouse BackupJob created again under a name whose Backup still exists now fails instead of reporting that Backup as its result. fix(backups): the backup controller now re-renders the Velero BSL, the default backup strategies and the platform bucket's credentials Secret when their S3 endpoint is stale, so after the platform bucket's BucketAccess is re-granted for a new publishing.host, backups move to the new endpoint without forcing releases by hand. fix(securitygroups): a SecurityGroup with attachments and no rules no longer leaves an invalid CiliumNetworkPolicy behind; its backing policy is now accepted by Cilium and still allows or denies nothing. fix(postgres): the init script renders the declared databases in a stable order, so an upgrade that leaves the databases unchanged no longer rewrites the init-script Secret. fix(mariadb-operator): the MariaDB operator now uses the platform's networking.clusterDomain instead of a hard-coded cozy.local, so replication and User/Database/Grant reconciliation work on clusters with a non-default cluster domain. fix(redis): an instance with `replicas: 1` now runs one Sentinel instead of three, without a Sentinel PodDisruptionBudget; on upgrade, the PDB the operator created earlier is deleted. Instances with two replicas or more are unchanged. fix(lineage, kubernetes): the virt-launcher pods of Kubernetes worker nodes are now resolved to their Kubernetes application and marked as managed by Cozystack, so a SecurityGroup attached to a Kubernetes cluster now applies to its worker nodes, not only to its control plane. fix(api): tenant quota admission now counts the parent pool's usage of extended resources and hugepages, so a child tenant can no longer get a share the parent has already used. After upgrading, updates to existing tenants may be rejected if their quota for these resources exceeds the parent's remaining budget. This includes updates that leave the quota unchanged. fix(postgres): a Postgres BackupJob now fails as soon as its CloudNativePG Backup fails, with the recorded error, instead of after 30 minutes, and a BackupJob waiting on a CloudNativePG Backup reports a WaitingForCNPGBackup condition with the Backup's phase. fix(postgres): databases now refuses the PostgreSQL system databases postgres, template0 and template1, and the init job never runs DROP DATABASE on them. A system database a previous version took over is handed back to the superuser on the next upgrade (event trigger removed, ownership and public schema restored, its <db>_admin and <db>_readonly roles dropped). A release that declares one of them must remove the entry before upgrading. fix(mariadb): a MariaDB BackupJob or RestoreJob whose operator Job failed now ends Failed instead of Succeeded, and a failed backup no longer creates a Ready Backup without an archive. Backups created by failed runs before this fix are not removed; restoring from one can fail or select another dump from the shared prefix. fix(kubernetes, monitoring): the vmagent of tenant Kubernetes clusters now writes to the tenant's vminsert and labels series with the owning tenant instead of `cozy-monitoring`. Previously no tenant cluster metric reached the tenant's Monitoring. ```

## What this PR does Backports to `release-1.7` from `main`, picked by the rules of the [backport policy](https://github.com/cozystack/cozystack/blob/main/docs/release/backports.md) in merge order. A merged pull request comes as its own commits, picked with `git cherry-pick -x` so each keeps its author, message and sign-offs, and a merge commit that carries the original's merge message with a `Backported-from:` trailer naming it; a squash-merged one comes as one pick. `backport-batch verify` checks that shape. A pick listed as changed differs from the commit it came from; `git range-diff <merge>^1..<merge>^2 <batch merge>^1..<batch merge>^2` shows how. A conflict or a failing check here is a [backport task](https://github.com/cozystack/cozystack/blob/main/docs/release/backport-tasks/README.md). -
