feat(stalwart): MTA-STS routes as a maintainable list, in both routing modes
The policy route for mta-sts.<domain> belonged to another repository
(jk-cluster-config) while pointing at this chart's own Service. It moves
here as mtaSts.hosts, a list, so several domains - subdomains included -
are maintainable in one place and in whichever routing mode is active.
THE LIST IS THE SWITCH. No mtaSts.enabled: "enabled with an empty list"
would be a state with no meaning that the chart would then have to catch.
The schema rejects the key outright, so the rule is enforced rather than
documented. Default [] renders nothing in either mode - the defaults and
the unchanged CI fixture both produce a byte-identical helm template
against origin/main.
Entry form {host, tlsSecretName, clusterIssuer?}. The two TLS fields are
read ONLY in Ingress mode; in Gateway mode TLS sits on the listener, so
requiring them there would demand a value that does nothing.
THE PATH IS HARDWIRED. RFC 8461 fixes /.well-known/mta-sts.txt, rendered
with pathType Exact (type: Exact in the route). A values key for a
protocol-mandated path can only ever be set wrong, and wrong is invisible
from this side. Exact also matters in itself: a prefix on these hostnames
would publish the mail server's whole management surface under them.
ONE INGRESS PER CLUSTER ISSUER, NOT ONE OBJECT - and the plan's own three
requirements forced that. cert-manager reads the two fields at different
scopes: cluster-issuer is an ANNOTATION (object-scoped, and absent means
nothing is issued for that object at all), while secretName is
tls-entry-scoped and yields one Certificate per entry. So an object cannot
both request a certificate and leave another host's secret alone, which is
what an empty per-entry issuer has to mean. Measured in jk-cluster:
ingress-shim names the Certificate AFTER THE SECRET and owns it from the
Ingress, so a shared secret must sit in exactly one object (hence grouping
the tls list by secret, reusing rss-bridge.tlsGroups' shape) and a secret
may not span two issuer groups (hence the abort). Objects are named by
issuer, not by index: an index is only free where the object holds no
certificate, which is the precondition homeassistant's route naming states
for itself.
Gateway mode renders ONE HTTPRoute with every hostname - nothing differs
per host there - attached to the same Gateway(s) as the WebUI route.
WHAT THE CHART CANNOT PROMISE, AND THEREFORE NAMES: it registers a route,
it does not create a domain. The domains live in Stalwart's data store, so
an entry whose domain is missing there answers 404 at a correctly routed
endpoint with every object green - and MTA-STS failures are silent on the
SENDER's side, which delivers in the clear and logs nothing here. Same for
the _mta-sts.<domain> TXT record and the policy's content. The subdomain
trap is documented too: mta-sts.sub.<domain> is one label below
*.<domain>, so a parent wildcard certificate does not cover it.
Not folded into certificate.extraDnsNames deliberately - that would hang
the MAIL certificate on this list, letting a bad policy entry take STARTTLS
and IMAPS with it.
Minor, additive, empty default: 1.2.0+upv0.16.25 -> 1.3.0+upv0.16.25.
CI: ci/httproute/stalwart.yaml enters all three shapes of the entry form
(with issuer, without, and a subdomain), taking the HTTPRoute render test
from 56 assertions over 21 charts to 58 over 21 - stalwart from 2 to 4.
The Ingress half cannot be covered there, since an overlay's whole job is
to switch the mode off, so ci/stalwart/test-values.yaml carries two
entries and the install-test has a real API server accept them.
Fixes #123

feat(stalwart): Gateway-API as an alternative to the Ingress
Group 3 of the #114 sweep. ONE route - not one per node group. #114 describes this chart as rendering "per node group"; its SERVICES and StatefulSets are, the routing object is not and must not be. The route targets exactly ingress.nodeGroup's own http Service and keeps both of the Ingress's guards, because the WebUI's setup and management screens are not safe to spread over a group that may not run the management tasks. ingress.nodeGroup is therefore shared by both modes: it names where the management surface is published from, which is not a property of the Ingress. THE MAIL CERTIFICATE STAYS, and this is the only chart in the sweep where anything of the TLS path does. stalwart.certificate.yaml covers STARTTLS on 25 and implicit TLS on 465/993; those connections pass through neither an ingress controller nor a Gateway. So in Gateway mode ingress.domain is still required (the certificate's dnsNames read it), ingress.clusterIssuer is still required unless certificate.clusterIssuer is set, and the Certificate must NOT be removed as part of a migration - deleting it drops SMTP and IMAP back to Stalwart's self-signed certificate, with clients seeing a name mismatch while every Kubernetes object stays green. Verified in the render: Gateway mode emits Certificate + HTTPRoute and no Ingress. WHAT THIS MODE DROPS - AND HERE IT BREAKS A SECOND CHART OF THE SAME GROUP. Measured on 2026-10-12, the live Ingress on mail.bekemeyer-klein.de carried, all of it operator-supplied through ingress.annotations (this chart sets none of it): enable-cors: true cors-allow-origin: https://webmail.bekemeyer-klein.de cors-allow-methods: GET, POST, OPTIONS cors-allow-headers: Authorization, Content-Type That origin is BULWARK, the webmail chart in this same group. Without the CORS configuration the browser-side webmail cannot call this server's JMAP endpoint at all, and the failure is entirely client-side: a console error, nothing in the server's logs. AND "no counterpart" WOULD HAVE BEEN WRONG. Measured by grepping the CRDs this repo pins (gateway-api v1.6.3 standard channel, ci/gateway-api-crds.sh) rather than inferred: HTTPRoute's filters carry a full 'cors' field (GEP-1767) with allowOrigins/allowMethods/allowHeaders/allowCredentials/maxAge, and its documented level - verbatim from that CRD - is "Support: Extended". responseHeaderModifier is in the same CRD and is also Extended, not Core. The chart still does not render it, for three reasons in order: 1. The chart has NO CORS values. The live configuration is the operator's, and the chart sets no CORS annotations in Ingress mode either - so rendering a filter means inventing a values surface that would exist in Gateway mode only. That asymmetry is its own defect and its own work. 2. Extended support is not support. A rejected route is rejected WHOLE, which would take the WebUI and JMAP down together (the reasoning #119 reached for statusCode); and the observed failure is quieter - Cilium accepts filters.type: CORS and forwards the preflight upstream anyway (cilium/cilium#45272), i.e. Accepted: True with the behaviour absent. 3. Half a CORS is worse than none, and the translatable half is the useless one HERE. A responseHeaderModifier can add the Access-Control-Allow-* headers; the PREFLIGHT has to be answered BY THE GATEWAY, which the CORS filter's own contract states and a bare header filter cannot do. Because the allowed headers include Authorization, EVERY webmail request is preflighted - so the expressible half is exactly the half that does not help. Named, not rebuilt (decision 2 of #114), in values.yaml, in the schema and in the Gateway branch of NOTES.txt, with the operational instruction: configure CORS at the Gateway with that implementation's own support BEFORE moving this host, and test it from the webmail in a browser - curl sends no preflight, so it passes while the webmail fails. NOTES.txt now asks $published (ingress.enabled OR httpRoute.enabled) where it asked ingress.enabled, and two paragraphs that named the ingress controller specifically now name the Gateway in that mode: the auto-ban step (switching API does not avoid or reset it - one proxy address instead of another) and the NetworkPolicy paragraph, where the namespace to allow is the Gateway's data plane rather than an ingress controller's. Minor: additive, defaults unchanged. Empty helm template diff against origin/main with ci/stalwart/test-values.yaml. Part of #114 |
