feat(proxmox-network): own the Proxmox bridge, VLANs and IP pools of tenant networks - #5047
On a Proxmox-backed tenant cluster the tenant still writes the bridge, the VLAN tag and the address range of its worker VMs into its Kubernetes and KubernetesNodes values, so nothing keeps one tenant's workers off another tenant's VLAN. This PR gives those three to the platform. The admin lists the tenant networks of a VLAN-aware bridge in a cluster-scoped ProxmoxNetworkZone; the new opt-in package cozystack.proxmox-network renders that table and one namespaced InClusterIPPool per network; the tenant writes one name, proxmox.network.name. Three ValidatingAdmissionPolicies, with the zone object as their parameter, keep Cluster API machines on the networks their namespace owns.
Nothing runs: no controller, no image, no Kube-OVN objects, no OVN writes. A VLAN is in use exactly while it is listed in the zone table. L3 between tenant VLANs stays on the operator's router, as on main today. The VPC-backed subnets of #4813 are the follow-up (cozystack/community#93); that draft stays open for reference only.
The commits can be reviewed one by one:
feat(proxmox-network-crds): the ProxmoxNetworkZone CRD, written by hand. Its schema refuses a network on the uplink VLAN, a VLAN used twice in one zone and a bridge among its own uplink bridges; (namespace, name) is a list-map key, so the apiserver keeps it unique without a CEL rule.
feat(proxmox-network): the package: zones and pools from values.yaml; the three policies (zone-binding with one binding per zone, cluster-pools, and raw-networks for the migration, off by default); one alert through kube-state-metrics; a read-only role for tenants on the pools of their namespace.
feat(cozy-lib): cozy-lib.proxmox.network turns a network name into the zone's bridge, the VLAN, the MTU, the gateway, the prefix and the pool name. It takes only the entry owned by the release namespace and fails the render with the reason when the network is in no zone, in two, or without its pool yet.
feat(kubernetes): proxmox.network.name. The ProxmoxCluster's ipv4Config, which capmox insists on, becomes a sentinel that holds only the gateway, an address the IPAM provider never hands out. A range next to a network name is refused.
feat(kubernetes-nodes): proxmox.network.name for net0: the zone's bridge, the network's VLAN and MTU and an ipv4PoolRef to the network's pool. A raw bridge or VLAN next to the name is refused.
feat(platform): the package joins the iaas bundle behind bundles.enabledPackages, depends on the in-cluster IPAM provider only, and its CRD chart installs first. kube-state-metrics exports the pools' addresses, and the kubernetes and kubernetes-nodes resource definitions carry the new field.
test(e2e): the proxmox-network Chainsaw suite for the regular lanes, no hypervisor needed. It applies the capmox CRDs alone and dry-runs every policy rule, each refusal next to an admitted request of the same shape.
docs(proxmox-network): the package README.md: objects, the zone table, the router, admission, the migration from the raw path, the alert.
Changes that reach existing installations
kubernetes-nodes, every installation:proxmox.network.bridge is no longer required in values.schema.json. The chart still fails the render of a Proxmox pool that sets neither bridge nor name. Nothing else changes for a cluster that does not set proxmox.network.name.
Only with the package enabled: the zone-binding and cluster-pools policies judge ProxmoxMachine, ProxmoxMachineTemplate and ProxmoxCluster on CREATE, and on UPDATE of the network part of the spec, in every namespace that owns a network. Clusters on the raw bridge/VLAN path are left alone until admission.rawNetworks is set to Warn or Deny.
Known limits
L3 between tenant VLANs is the operator's router. The platform renders the table it needs (kubectl get pxzone -o yaml) and nothing more; routing inside the platform's own network is the subject of the follow-up proposal.
No dynamic VLAN allocation: the zone is a static table the admin writes. Removing a network deletes its pool, which the IPAM webhook refuses while an address is still claimed, so the release upgrade fails visibly until the network's last VM is gone.
IPv4 only. One network per pool, on net0; no additionalNetworks.
Admission does not cover VMs created outside Cluster API, nor a bridge over the uplink's parent device that is not listed in uplinkBridges.
make helm-unit-tests: 4047 tests on 108 charts, all passing. Among them 21 for proxmox-network, 1 for proxmox-network-crds, 8 for cozy-lib, 5 new for kubernetes (351 in all), 7 new for kubernetes-nodes (230, 12 snapshots unchanged), 2 for platform (289) and 1 for monitoring-agents (21).
make go-unit-tests (11 packages) and make rd-presets-check; go build ./api/... && go vet ./api/....
chainsaw lint test on the suite; the package rendered from the suite's test-values.yaml passes kubectl apply --dry-run=client; hack/select-install.sh --validate; hack/check-commit-trailers.sh on the range.
The three policies and their bindings passed a server-side dry run on a Kubernetes 1.35.2 cluster, so the CEL compiles against a real apiserver. Their behaviour on live capmox objects is what the e2e suite checks.
Not run locally: the Chainsaw suite, which runs for the first time in this PR's e2e lane, and the Bats tests (bats is not installed on the host; the body of the new test ran as plain bash). The deepcopy for the new kubernetes type is written by hand in the generator's shape, because hack/update-codegen.sh does not run with the Go toolchain on the host; the codegen-drift job will show whether it matches byte for byte.

Downstream repositories
Walked against the diff: a new platform component and a new opt-in package in the iaas bundle (website), a new nested field in the kubernetes and kubernetes-nodes schemas (terraform-provider), and the proposal (community). No installer values, release assets, ApplicationDefinition semantics or developer tooling change.
No downstream repository is affected by this change
feat(proxmox-network): a new opt-in `cozystack.proxmox-network` package gives the platform the bridge, the VLAN and the IP pool of every Proxmox-backed tenant cluster. The admin lists tenant networks in a `ProxmoxNetworkZone`, the package renders one namespaced `InClusterIPPool` per network, and ValidatingAdmissionPolicies keep Cluster API machines on their namespace's networks. `Kubernetes` and `KubernetesNodes` take `proxmox.network.name` in place of a raw bridge, VLAN and address range; `proxmox.network.bridge` in kubernetes-nodes is no longer required by the schema.

Summary by CodeRabbit
New Features
Added an opt-in Proxmox networking package for configuring tenant networks, including bridges, VLANs, address pools, and network access policies.
Kubernetes clusters and worker pools can now select a tenant network by name. Its IP pool supplies worker addresses; existing explicit bridge and address-pool configuration remains available when no network is selected.
Added IP pool usage metrics and alerts for pools nearing capacity.
Documentation
Added setup, configuration, and testing guidance for Proxmox tenant networking.

Summary
Define the network zone API and install its CRD packages/system/proxmox-network-crds/*, packages/core/platform/sources/proxmox-network.yaml, packages/core/platform/tests/sources_proxmox_network_test.yaml
Adds the ProxmoxNetworkZone CRD and a package component that installs the CRD before the network component.
Adds machine and cluster admission policies for tenant networks, plus configurable validation for raw-network machine NICs.
Resolve tenant networks by namespace and name packages/library/cozy-lib/templates/_proxmox.tpl, packages/tests/cozy-lib-tests/templates/tests/proxmox-network.yaml, packages/tests/cozy-lib-tests/tests/proxmox_network_test.yaml, api/apps/v1alpha1/kubernetes/types.go, api/apps/v1alpha1/kubernetes/zz_generated.deepcopy.go, api/apps/v1alpha1/kubernetesnodes/types.go
Adds the network lookup helper, its tests, and API types for named Proxmox networks. The helper returns network settings only when it finds a unique namespace-and-name match and the matching IP pool.
Use named networks in cluster and node-pool configuration packages/apps/kubernetes/templates/cluster.yaml, packages/apps/kubernetes/values.yaml, packages/apps/kubernetes/values.schema.json, packages/apps/kubernetes/tests/substrate_proxmox_network_test.yaml, packages/apps/kubernetes-nodes/templates/nodegroup.yaml, packages/apps/kubernetes-nodes/values.yaml, packages/apps/kubernetes-nodes/values.schema.json, packages/apps/kubernetes-nodes/tests/substrate_proxmox_network_test.yaml, packages/system/kubernetes-rd/cozyrds/kubernetes.yaml, packages/system/kubernetes-nodes-rd/cozyrds/kubernetes-nodes.yaml, packages/apps/kubernetes/README.md, packages/apps/kubernetes-nodes/README.md
Adds named-network options to cluster and node-pool values and schemas. Templates render network-derived cluster gateway and worker NIC settings, and retain the raw configuration paths.
Wire the opt-in platform package packages/core/platform/templates/bundles/iaas.yaml, packages/core/platform/tests/bundles_proxmox_network_wiring_test.yaml, packages/core/platform/tests/fixtures/selective-install-postgres-values.yaml, hack/e2e-platform-packages.sh, hack/platform-packages_test.bats
Adds opt-in package emission and enforces its dependency on the in-cluster IPAM provider. Updates package-selection fixtures and tests.
Exercise package installation and network behavior hack/e2e-chainsaw/proxmox-network/*, hack/e2e-chainsaw/README.md
Adds end-to-end checks for package resources, zone validation, admission behavior, IP allocation, and pool deletion while an address is claimed.
The zone admission policy likely fails on an unescaped reserved CEL property name. Where its binding applies, Proxmox machine writes could then be denied. Tenant releases also copy zone networking values at render time, so they can go stale after a zone edit. Fix the CEL escape and resolve the lookup concern, by moving the zone data to values or recording maintainer authorization, before merging.

A note on this PR's first E2E run: the proxmox-network suite passed, but its admission step did not test what it says. Every ProxmoxMachine probe lacked a templateSelector, so capmox's own CRD rule refused all fourteen of them before any of the three policies ran, and the harness lost those failures: each probe pipes into admitted/refused, which run in a pipeline's subshell, so fail=1 never reached the step's exit status. The ProxmoxCluster cases, the template update, the CRD validation, the pools and the held pool did run and pass.
The fix pushed here gives every probe a templateSelector and counts failures and executed checks in files, so the step fails unless all of its checks ran and passed. Run against a fake kubectl that admits or refuses everything, the old harness exits 0 on the CRD step and the new one exits 1 on both steps. The next E2E run is the first that exercises the machine rules.
A cluster-scoped ProxmoxNetworkZone is the admin's table of Proxmox
tenant networks on one VLAN-aware bridge: per network the owning
namespace, the VLAN, the address range, the gateway and the prefix. It
is the parameter the admission policy and the kubernetes and
kubernetes-nodes charts will read; nothing writes a status to it.
The CRD is written by hand, without Go types or controller-gen. The
schema refuses a network on the uplink VLAN, a VLAN used twice in one
zone and a bridge listed among its own uplink bridges; (namespace, name)
is a list-map key, so the apiserver keeps it unique without a CEL rule
whose cost would grow with the square of the table. The chart keeps the
CRD on uninstall, as the other CRD charts do.

…tenant networks
The package renders the admin's zone table: a ProxmoxNetworkZone per
VLAN-aware bridge and one InClusterIPPool per tenant network, in the
namespace that owns it, so a worker's bridge, VLAN and address never
come from tenant values. Nothing runs: no controller, no image.
Three ValidatingAdmissionPolicies keep Cluster API machines on those
networks. The zone policy takes the zone object as its parameter, one
binding per zone, and judges only that zone's bridge, so a namespace
with networks in two zones passes both; it also keeps the zone's uplink
VLAN and uplink bridges off every NIC. The cluster-pools policy holds a
ProxmoxCluster's own ipv4Config to the gateways of its namespace's
networks, so capmox has nothing of its own to hand out. The raw-networks
policy, off by default, warns about or refuses NICs that are not on a
zone bridge with a platform pool, for the migration from the raw
bridge/vlan path. UPDATE is judged only when the network part of the
spec changes, since capmox keeps updating its machines.
The one alert reads the pools' status through kube-state-metrics, and a
tenant may read the pools of its namespace.

cozy-lib.proxmox.network turns the name of a tenant network into what
a capmox NIC and a ProxmoxCluster need: the zone's bridge, the VLAN,
the MTU, the gateway, the prefix and the name of the InClusterIPPool.
It reads the cluster-scoped ProxmoxNetworkZone table and takes only the
entry owned by the release namespace, so a name cannot reach another
tenant's network, and it fails the render with a message naming what is
missing: the network is in no zone, in two zones, or its pool is not
rendered yet. The kubernetes and kubernetes-nodes charts use it.

… network
proxmox.network.name names a Proxmox tenant network the platform
operator listed for this namespace in a ProxmoxNetworkZone. With it the
chart no longer takes an address range from the tenant: the workers of
every node pool on that network claim their addresses from the
network's own InClusterIPPool, and the ProxmoxCluster's ipv4Config,
which capmox insists on and builds a pool from, becomes a sentinel that
holds only the network's gateway, an address the IPAM provider never
hands out. A range next to a network name is refused, and clusters
without a network keep the ipv4Config path.
The deepcopy for the new type is written in the generator's shape;
update-codegen.sh does not run against the toolchain on this host.

…ant network
proxmox.network.name names a Proxmox tenant network the platform
operator listed for this namespace in a ProxmoxNetworkZone. The pool's
net0 then takes the zone's bridge, the network's VLAN and MTU, and an
ipv4PoolRef to the network's own InClusterIPPool, so every worker
address comes from a pool the platform rendered and the tenant never
picks a bridge, a VLAN or a range. A raw bridge or VLAN next to the
name is refused, since that is exactly how a tenant would reach a VLAN
that is not theirs. Pools without a network keep the raw bridge/vlan
path, which the proxmox-network package can warn about or refuse.

cozystack.proxmox-network joins the iaas bundle behind
bundles.enabledPackages, like capmox, and brings the IPAM provider
along: every tenant network's addresses live in an InClusterIPPool.
Its only dependency is that provider; neither Kube-OVN nor capmox is
needed for a zone table and its pools to exist. The CRD component
installs first, so the zones render on the package's first install.
kube-state-metrics exports the pools' total, used and free addresses,
which the package's one alert reads, and the kubernetes and
kubernetes-nodes resource definitions carry the new network field.

…rvisor
The proxmox-network suite runs in the regular lanes. The package runs
nothing, so what a cluster shows is what the apiserver does with its
objects: the zone CRD refuses a VLAN used twice, a network on the
uplink VLAN, a bridge among its own uplink bridges and a network listed
twice; every network gets its pool in the namespace that owns it; the
admission policies keep Cluster API machines on their namespace's
networks on CREATE and UPDATE, compose across two zones, refuse the raw
path with rawNetworks Deny and hold a ProxmoxCluster to its gateways;
a binding whose zone is gone denies; and the IPAM webhook refuses to
delete a pool with an address in use. Every refusal sits next to an
admitted request of the same shape.
capmox is not installed in these lanes, so the suite applies its CRDs
alone for the dry runs and removes them at the end. The package is
enabled for the e2e install and the selector drops it from runs that
do not select the suite.

The selector app.kubernetes.io/managed-by=proxmox-network with -A matches every pool that the package renders. The suite does not own all of them. Someone who runs it locally on a cluster with real zones deletes the unused real pools. The suite already labels its own pools with proxmox.cozystack.io/zone (see the pools step), so use that label.

Update the InClusterIPPool cleanup command to select only the suite’s zones
using the proxmox.cozystack.io/zone label, matching the zone values created by
the pools step; preserve the existing timeout, resource, namespace, and
ignore-not-found behavior.
The refusal on line 374 depends on the apiserver loading the new pxnet-e2e-ghost binding. A slow apiserver can still admit the request after 5 seconds. The step then fails with "admitted" and the failure does not point to a policy defect. A fixed delay also adds 5 seconds when the binding is ready sooner. Retry the dry run until it is refused, with an upper time limit, and then run the refused check.

Add render-time checks for duplicate zone names and duplicate VLANs.
Add render-time checks for duplicate zone names and duplicate VLANs.
The header comment says wrong values fail the release with a message. Two cases do not.
Two zones with the same name and different bridges pass the bridge check. Both render a ProxmoxNetworkZone with one metadata.name, and the second create fails with a generic "already exists" error.
Two networks in a zone with the same vlan are caught only by the CRD CEL rule. That rule is not applied when the Capabilities gate on Line 60 is false, for example with offline helm template or helm-unittest.
README.md Line 35 says the chart refuses "the rest" at render time. That claim does not hold for the duplicate-VLAN case. VLAN uniqueness is the tenant-isolation invariant, so check it here as well.

Add render-time tracking in the zones template so repeated zone names fail
before resources render, and repeated VLANs within the same zone fail regardless
of the Capabilities gate. Keep VLAN uniqueness scoped to each zone and retain
the existing bridge-uniqueness check using $bridges.
Do not copy zone values into the render with lookup. Move them to values, or get maintainer authorization for this lookup.
The helper reads every ProxmoxNetworkZone at render time. It then copies bridge, vlan, mtu, gateway, and prefix into its output. Both callers consume that output: packages/apps/kubernetes/templates/cluster.yaml (line 941) and packages/apps/kubernetes-nodes/templates/nodegroup.yaml (line 206). Nothing re-renders the tenant HelmRelease when an operator edits a zone. The rendered VLAN, bridge, and gateway therefore stay stale until an unrelated change upgrades the release. The template header records no maintainer authorization for this lookup.
The repository rule (docs/agents/overview.md) forbids a lookup that copies another object into the render unless a maintainer authorizes that specific lookup. The existence check on line 41 is the allowed kind. Its empty branch must keep rendering, but line 42 fails that branch. The fail calls on lines 31 and 42 therefore abort offline renders, such as helm template without a cluster. Line 36 fires only when a network is listed twice, so it does not affect offline renders.
Take these facts from values instead. Read the namespace or cluster from _namespace or _cluster in the cozystack-values Secret. Or read the zone data through valuesFrom, so a content change upgrades the release. Keep the existence check on line 41 as the only lookup. If a maintainer has authorized the zone lookup, record that authorization in the PR and in the template header.

Escape the namespace property in the CEL expression.
namespace is a reserved CEL property name. The ProxmoxNetworkZone parameter must use n.__namespace__, not n.namespace. Otherwise, the zone policy cannot reliably compile or evaluate its network ownership variable.

Update the ProxmoxNetworkZone CEL network filter to compare n.__namespace__ with
request.namespace instead of accessing n.namespace, so the ownership expression
uses the escaped property name.

Quote namespace and the label values.
The CRD patterns allow names and namespaces made only of digits (for example 201). The label values on Lines 22-23 and namespace on Line 19 are rendered unquoted. YAML parses these as integers. The apiserver then rejects the pool because label values and metadata.namespace must be strings. pxnet-{{ $n.name }} on Line 18 is safe because of the prefix. A VLAN-named network such as 201 is a realistic input.

Update the pool template’s `namespace` field and `proxmox.cozystack.io/zone` and
`proxmox.cozystack.io/network` label values to render as quoted strings,
preserving the existing `app.kubernetes.io/managed-by` label and prefixed
resource name.

Quote .name in metadata.name.
The CRD pattern for names allows all-digit values. A zone named 70 renders as name: 70. YAML parses that as an integer, and the apiserver refuses the object. Quote the value, as the other string fields in this template already are.
IMPORTANT
Review the replacement and indentation, then test before committing.

66:
Quote the `.name` value in the `metadata.name` field of the zone template so
all-digit zone names render as YAML strings. Leave the other fields unchanged.

What this PR does
Part of #3481. Design proposal: cozystack/community#104, the first piece split out of cozystack/community#93 after its review.
On a Proxmox-backed tenant cluster the tenant still writes the bridge, the VLAN tag and the address range of its worker VMs into its
KubernetesandKubernetesNodesvalues, so nothing keeps one tenant's workers off another tenant's VLAN. This PR gives those three to the platform. The admin lists the tenant networks of a VLAN-aware bridge in a cluster-scopedProxmoxNetworkZone; the new opt-in packagecozystack.proxmox-networkrenders that table and one namespacedInClusterIPPoolper network; the tenant writes one name,proxmox.network.name. Three ValidatingAdmissionPolicies, with the zone object as their parameter, keep Cluster API machines on the networks their namespace owns.Nothing runs: no controller, no image, no Kube-OVN objects, no OVN writes. A VLAN is in use exactly while it is listed in the zone table. L3 between tenant VLANs stays on the operator's router, as on
maintoday. The VPC-backed subnets of #4813 are the follow-up (cozystack/community#93); that draft stays open for reference only.The commits can be reviewed one by one:
feat(proxmox-network-crds): theProxmoxNetworkZoneCRD, written by hand. Its schema refuses a network on the uplink VLAN, a VLAN used twice in one zone and a bridge among its own uplink bridges; (namespace,name) is a list-map key, so the apiserver keeps it unique without a CEL rule.feat(proxmox-network): the package: zones and pools fromvalues.yaml; the three policies (zone-bindingwith one binding per zone,cluster-pools, andraw-networksfor the migration, off by default); one alert through kube-state-metrics; a read-only role for tenants on the pools of their namespace.feat(cozy-lib):cozy-lib.proxmox.networkturns a network name into the zone's bridge, the VLAN, the MTU, the gateway, the prefix and the pool name. It takes only the entry owned by the release namespace and fails the render with the reason when the network is in no zone, in two, or without its pool yet.feat(kubernetes):proxmox.network.name. TheProxmoxCluster'sipv4Config, which capmox insists on, becomes a sentinel that holds only the gateway, an address the IPAM provider never hands out. A range next to a network name is refused.feat(kubernetes-nodes):proxmox.network.namefor net0: the zone's bridge, the network's VLAN and MTU and anipv4PoolRefto the network's pool. A raw bridge or VLAN next to the name is refused.feat(platform): the package joins the iaas bundle behindbundles.enabledPackages, depends on the in-cluster IPAM provider only, and its CRD chart installs first. kube-state-metrics exports the pools' addresses, and the kubernetes and kubernetes-nodes resource definitions carry the new field.test(e2e): theproxmox-networkChainsaw suite for the regular lanes, no hypervisor needed. It applies the capmox CRDs alone and dry-runs every policy rule, each refusal next to an admitted request of the same shape.docs(proxmox-network): the packageREADME.md: objects, the zone table, the router, admission, the migration from the raw path, the alert.Changes that reach existing installations
