feat(kubernetes-nodes)!: registry TLS for worker pools and an atomic osImage - #5192
Stacked on #5191, which cleans up the kubernetes-nodes descriptions this PR edits. Merge that one first. The base of this PR is its branch, so the diff here shows only the two commits below.
Two changes to the KubernetesNodes chart, one commit each.
osImage gets x-kubernetes-map-type: atomic. builtin and factory exclude each other and the chart refuses a pool that sets both, so a default for one of them merged into a pool that chose the other builds that object. The marker alone changes nothing on main: nothing reads it yet, the application defaults merge in #5107 does. That PR has the same marker change, so whichever of the two merges second only needs make generate for the ApplicationDefinition (it is one line of JSON).
A pool could mirror a registry but could not tell its workers to trust the mirror's CA, so an in-cluster mirror behind an internal CA failed on x509. talos.registryMirrors now renders as RegistryMirrorConfig documents, and the new talos.registryConfig renders a RegistryTLSConfig per endpoint that sets tls.ca or tls.insecureSkipVerify. The deprecated machine.registries section is no longer rendered. Credentials and client identity are refused instead of ignored, the rendered text is readable in the tenant namespace. tls.ca goes through the same PEM validator as imageFactoryCA, so a private key is refused too. Switches take true or false only, any other spelling fails the render instead of leaving a switch off.
This is breaking for a pool on Talos below 1.12 that already sets registryMirrors: the documents exist from 1.12, so the render fails now and names the pool and the release. Cozystack supports workers on 1.13 and newer. Running workers are not touched.
Pools with registryMirrors get a new TalosConfigTemplate name and their workers roll once on upgrade. Pools without mirrors render byte for byte as before: the full helm template output of origin/main and this branch is identical for a default pool and for a pool on Talos 1.11 without mirrors, and the 12 render snapshots pass.
Tested on a cluster running v1.7.0 with this branch on top. The CAPI Talos bootstrap provider passes both documents through with generateType: none. A worker with the mirror and the CA pulled kubelet and cilium images through an in-cluster mirror and joined, a worker with the mirror only failed on x509 and never joined, and a port in a RegistryTLSConfig name works on a node. Not tested on a node: a port in a RegistryMirrorConfig name (only talosctl validate) and the worker roll after a registryMirrors change. The Talos 1.12 reference uses my-mirror.local:5000 as a RegistryTLSConfig name and a raw PEM for ca.
Generated files come from make generate with cozyvalues-gen v1.7.0. Full make unit-tests passes with LC_ALL=C.
Summary by CodeRabbit
New Features
Added per-registry TLS configuration for Talos workers, including certificate authority settings.
Expanded registry mirror options, including fallback controls and path overrides.
Registry configuration is checked for supported settings and Talos version compatibility; changes can trigger worker rollouts.
Documentation
Clarified that choosing an OS image source replaces the entire image configuration rather than merging with defaults.

Walkthrough
The change documents atomic osImage behavior and adds Talos registry mirror and TLS configuration. The template validates registry settings and resolved Talos versions, then appends escaped registry documents to the reconcile configuration.
The values and schemas describe osImage as atomic and document registry mirror and TLS options. Talos.DeepCopyInto copies RegistryConfig. Schema tests check the atomic marker.
Registry document rendering and validation packages/apps/kubernetes-nodes/templates/_talosconfigtemplate.tpl, packages/apps/kubernetes-nodes/tests/registry_mirrors_test.yaml, hack/talos-reconcile-heredoc_test.bats
The template validates mirror and TLS inputs, applies the Talos 1.12 version gate when it generates registry documents, and appends escaped documents. Tests cover generated output, invalid inputs, version checks, and shell escaping.

cozystack/cozystack#5107: Adds the osImage atomic-map marker and description text also present in this pull request.
Merge Risk: Moderate · previous review 3bc95
The registry TLS rendering accepts some malformed mirror URLs, TLS keys and CA certificates. A worker pool with such settings could roll and then fail to join. These validation gaps should be closed before merge, or the risk explicitly accepted. Pools without registry mirrors are reported to render unchanged.

Explanation
The title names the two main changes in the PR: registry TLS support for worker pools (the registryConfig/RegistryTLSConfig work and the registryMirrors rendering) and the atomic osImage marker. Both appear in the raw summary and the PR objectives. The conventional-commit prefix and the breaking-change marker match the scope of the change, which drops the deprecated machine.registries output and fails rendering on Talos versions below 1.12. The title is specific and does not use vague terms.

The registry tests check Job text but not the MachineDeployment reference. A name regression could prevent existing workers from receiving the new configuration. Add paired renders for mirror and CA changes that check name rotation and Job/reference agreement. Also check that empty settings preserve the default name.

Reject URL-shaped registry TLS keys before rendering.
If registryConfig uses https://mirror.example.org as a key, Talos does not match its CA to the mirror host. Image pulls can fail when the mirror requires that CA and upstream fallback is unavailable. Validate keys as hosts with optional ports.

Validate the TLS value before defaulting it.
If tls is false, 0, "", or [], default replaces it with an empty map. The render then silently omits the TLS configuration instead of reporting the malformed block.

## @param {WorkerImage} [osImage] - Worker OS image source for this pool. Default (omitted): import over HTTP from the `talos.*` Image Factory. Set `osImage.builtin` to clone a golden from the opt-in worker image catalog instead. Editing this on an existing pool re-images that pool. The object is atomic: its two sources exclude each other, so a value that sets one of them replaces the whole object and is never completed from a default.

Limit the atomic replacement promise to schema-aware merges.
Helm merges values files recursively. If a base file selects builtin and an overlay selects factory, the render fails because both keys remain. Document that Helm overlays must be combined before rendering; the atomic annotation does not make Helm replace osImage.

valid URLs using the template’s available URL-validation mechanism.

A truncated certificate can pass this PEM shape check and enter the worker bootstrap config. Talos rejects the config, so replacement workers cannot join. Validate the certificate before rollout and replace the MIIB test fixture with a valid certificate.

Update cozy-lib.tls.validateCACert, used before setting the registry CA in $doc,
to reject PEM values that are not valid X.509 certificates rather than only
checking their PEM shape; preserve the existing validation flow before worker
rollout. Replace the MIIB test fixture for this validation path with a valid
certificate.

The registry work is carefully done. What I checked:
A default pool, and a pool on Talos 1.11 without mirrors, render byte-for-byte identical to main (the full helm template diff is empty), so only pools that actually set mirrors roll on upgrade.
The below-1.12 guard fires with the pool name and the resolved Talos version, and does not fire for a 1.13 pool with mirrors or an 1.11 pool without them.
tls.ca goes through the same PEM validator as imageFactoryCA, so a private key or a malformed PEM fails the render; credentials and client identity are refused rather than dropped; the switches take only true/false and reject yes, 1 and a quoted false that truthiness would read as on.
machine.registries is fully replaced by the RegistryMirrorConfig documents, with no silent loss of config on upgrade.
The touched bats and the kubernetes-nodes helm-unittest suite pass on the branch merged with current main.
Notes, none blocking:
[MINOR] tls.ca: "" renders nothing and passes on any version, so a tenant who believes they set a CA gets none and no error. It is the one silent no-op in an otherwise strict validator.
[MINOR] Migration 56 copies the parent cluster's talos block into the pools, so a pool migrated with a mirror on Talos below 1.12 fails its HelmRelease on platform upgrade. That matches the breaking mark and running workers keep going, but the PR body only describes pools configured directly, not migrated ones.
The red "Build packages/*" checks are the "Set up flux" step getting HTTP 504 pulling the flux binary from GitHub releases, not this change. Worth a re-run.
The one thing no offline check covers is Talos and the CABPT provider accepting the multi-document data on a real node; the cluster run in the PR body covers it, I am only noting the suites do not.
osImage.builtin and osImage.factory exclude each other and the chart
refuses a pool that sets both. A default for one of them merged into a
pool that chose the other builds exactly that object, and the pool then
fails at render instead of at create. x-kubernetes-map-type: atomic
tells a merge to take osImage whole or leave it alone.

…gs as Talos documents
A pool could mirror a registry but could not tell its workers to trust
the mirror's CA or skip verification, so an in-cluster mirror served by
an internal CA was unusable: the worker's pulls failed on x509.
talos.registryMirrors now renders one RegistryMirrorConfig document per
host and the new talos.registryConfig one RegistryTLSConfig per endpoint
that sets tls.ca or tls.insecureSkipVerify. The deprecated
machine.registries section is no longer rendered. Both document kinds
exist from Talos 1.12, so a pool that resolves to an older release and
would render one now fails the render, naming the pool and the release.
That is breaking for a pool on Talos below 1.12 that already sets
registryMirrors: it rendered before and does not now, while its running
workers are untouched. Pools without mirrors and TLS settings render
what they rendered before.
What the old passthrough handed to the node unchecked is refused at
render: switches take true or false, endpoints are a list of non-empty
strings, and tls.ca must be a plain PEM certificate, through the shared
validator that also refuses private key material. Credentials and
client identity are refused rather than ignored, because the rendered
text is stored in the tenant namespace. A tls block that is false, 0, an
empty string or an empty list is refused too instead of being read as
empty, and so is a host or endpoint written as a URL, which Talos never
matches to a pull.
A pool that sets registryMirrors gets a new TalosConfigTemplate and its
workers roll, because the rendered machine config changes. The pool
chart's own text now says that only talos.version is kept in step with
the parent chart.

Stacked on #5191, which cleans up the kubernetes-nodes descriptions this PR edits. Merge that one first. The base of this PR is its branch, so the diff here shows only the two commits below.
Two changes to the KubernetesNodes chart, one commit each.
osImagegetsx-kubernetes-map-type: atomic.builtinandfactoryexclude each other and the chart refuses a pool that sets both, so a default for one of them merged into a pool that chose the other builds that object. The marker alone changes nothing on main: nothing reads it yet, the application defaults merge in #5107 does. That PR has the same marker change, so whichever of the two merges second only needsmake generatefor the ApplicationDefinition (it is one line of JSON).A pool could mirror a registry but could not tell its workers to trust the mirror's CA, so an in-cluster mirror behind an internal CA failed on x509.
talos.registryMirrorsnow renders as RegistryMirrorConfig documents, and the newtalos.registryConfigrenders a RegistryTLSConfig per endpoint that setstls.caortls.insecureSkipVerify. The deprecatedmachine.registriessection is no longer rendered. Credentials and client identity are refused instead of ignored, the rendered text is readable in the tenant namespace.tls.cagoes through the same PEM validator asimageFactoryCA, so a private key is refused too. Switches take true or false only, any other spelling fails the render instead of leaving a switch off.This is breaking for a pool on Talos below 1.12 that already sets
registryMirrors: the documents exist from 1.12, so the render fails now and names the pool and the release. Cozystack supports workers on 1.13 and newer. Running workers are not touched.Pools with
registryMirrorsget a new TalosConfigTemplate name and their workers roll once on upgrade. Pools without mirrors render byte for byte as before: the fullhelm templateoutput of origin/main and this branch is identical for a default pool and for a pool on Talos 1.11 without mirrors, and the 12 render snapshots pass.Tested on a cluster running v1.7.0 with this branch on top. The CAPI Talos bootstrap provider passes both documents through with
generateType: none. A worker with the mirror and the CA pulled kubelet and cilium images through an in-cluster mirror and joined, a worker with the mirror only failed on x509 and never joined, and a port in a RegistryTLSConfig name works on a node. Not tested on a node: a port in a RegistryMirrorConfig name (onlytalosctl validate) and the worker roll after aregistryMirrorschange. The Talos 1.12 reference usesmy-mirror.local:5000as a RegistryTLSConfig name and a raw PEM forca.Generated files come from
