| Moving back off an edge-terminated class restores whatever the mode the tenant lands in calls for: the ACME `Issuer` and its `Certificate`s under `http01` or `dns01`, the redirect route under any non-edge mode, and the wildcard replica whenever `publishing.certificates.wildcardSecretName` is set. `existingSecret` mints no `Issuer` and no `Certificate` of its own, so a move from `edge` into it brings back the replica and the redirect route and nothing else. | ||
|
|
||
| The two halves of the move are not ordered against each other. The wildcard-secret controller watches the `TenantGateway` and prunes the replica as soon as `certMode` changes, while the `Gateway` itself is re-rendered when the tenant's HelmRelease reconciles, and the class controller reprograms after that. A tenant leaving `existingSecret` can therefore be briefly serving HTTPS listeners whose Secret has already gone. |

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift
Preserve the wildcard Secret until the Gateway stops referencing it. When a tenant moves from existingSecret to http01 or dns01, the wildcard-secret controller can delete the replica before reconcileGateway replaces the HTTPS listeners. Retain the old Secret until the Gateway no longer references it, or coordinate the transition with an explicit readiness guard; otherwise the existing Gateway can lose TLS before replacement certificates are ready.

Align the verification commands with the preceding example. The example defines acme in tenant-root, but the commands query cozystack in tenant-acme. Align these values or explicitly mark them as placeholders before operators copy the commands.

Some GatewayClasses have their provider terminate TLS in front of the Gateway and reach it over plain HTTP. On such a class the platform issued origin certificates nobody serves, and where ACME could not complete, the Gateway's listeners never became ready. Add certMode=edge to TenantGateway. The controller renders the apex, its wildcard and every inheriting child apex as plain HTTP listeners carrying the same label-based allowedRoutes as the HTTPS listeners of the other modes, so application HTTPRoutes attach by hostname unchanged. It mints no Issuer and no Certificate, and removes the http-to-https redirect route, because the edge performs that redirect itself. TLSPassthroughServices are not rendered: an HTTP-only edge cannot carry a TLS listener, which leaves the endpoints relying on one unpublished through such a Gateway. The hostname-less port-80 listener is left out. It carries the ACME challenge and the redirect in the other modes and has neither here, so it would only be a catch-all admitting any hostname. Leaving it out also keeps a hostname-pinned listener at index 0, which is what Cilium's first-listener-wins namespace check reads before the fix in cilium/cilium#45693. Moving into the mode garbage-collects the Issuer and Certificate objects the controller owned. The TLS Secrets they issued stay behind: cert-manager runs with enableCertificateOwnerRef false, so a Certificate does not own the Secret it issued into. Every mode transition already behaves that way. Assisted-By: Claude <noreply@anthropic.com> Signed-off-by: Aleksei Sviridkin <3811295@gmail.com>
The wildcard-secret controller replicates the operator's TLS Secret, private key included, into every namespace that owns a termination point, and a namespace owning a Gateway counted as one without further question. A Gateway whose class ends TLS at its provider's edge terminates nothing locally, so the replica has no consumer there. Read certMode off the tenant's own TenantGateway rather than a cluster-wide value, because the class is a per-tenant choice. Keep the key whenever the answer is not a confident no: a namespace that also owns an ingress controller still terminates locally, a namespace holding more than one TenantGateway keeps it while any of them is not at the edge, and an unreadable list or a namespace whose TenantGateway has not appeared yet keeps it too, so a transient API error never withdraws a key a Gateway may still be serving. Watch TenantGateway, so the withdrawal follows the class change rather than waiting for the periodic resync. Pruning the replica is not the same as leaving the namespace key-free. The Certificate objects go, but the Secrets they issued stay, as they do on any other mode transition. Assisted-By: Claude <noreply@anthropic.com> Signed-off-by: Aleksei Sviridkin <3811295@gmail.com>
Tenant Gateways were pinned to the bundled Cilium class. Give the platform a default in gateway.className, the set a tenant may choose from in gateway.tenantSelectableClasses, and the set whose provider terminates TLS upstream of the Gateway in gateway.edgeTerminatedClasses. A tenant picks its own with tenant.spec.gatewayClass, read only when it owns a Gateway; an inheriting tenant runs on its ancestor's. The selectable set is an allowlist rather than free choice because Tenant is a tenant-writable object while a GatewayClass is cluster-scoped: without it a tenant could attach its Gateway to a class an admin keeps for internal-only traffic. Naming anything outside the set fails that tenant's own gateway release and reaches no other tenant. Where TLS ends is a property of the class, so the gateway chart derives certMode from whichever class the tenant landed on instead of taking it as a separate input. The two therefore cannot be configured out of step. The publishing tenant cannot cross that line by itself. The cluster-wide ACME issuers point their HTTP-01 solver at its Gateway and are rendered from the platform default alone, so a mismatch would pin the solver to a listener that Gateway does not have. Those issuers now drop the sectionName pin when the default class is edge-terminated, letting the challenge attach by hostname instead.

An operator setting up a class whose provider terminates TLS upstream had no page answering their questions: which platform values bound the choice, what a tenant writes to make it, what a move between classes does to certificates and to the replicated wildcard Secret, and how the mechanism fails when a configured class name matches nothing installed. Add docs/gateway-classes.md covering that surface. Describe the mode and its consequences in the chart README alongside the other three, including the one constraint stated nowhere else: the publishing tenant cannot select a class whose TLS termination differs from the platform default, because the cluster-wide ACME issuers derive their solver pin from that default alone.

The class lists arrive over the values channel comma-joined, so every reader trims each entry as it splits them. The scalar those entries are compared against was not trimmed anywhere. A class name carrying a stray space therefore failed `has` against its own padded self, and the two readers of that scalar disagreed about the same class: the gateway chart put the tenant on an edge-terminated class, while the cluster-wide ACME issuers still pinned their solver to a listener an edge Gateway does not render. That stops every HTTP-01 certificate in the cluster from issuing, with nothing in any status naming the cause. Normalise once at the single writer so both readers see a clean value, and keep a defensive trim at each reader. The tenant's own choice does not travel that channel — it comes from tenant.spec.gatewayClass — so it is trimmed where the gateway chart reads it. Unset and whitespace-only are different events and no longer share an outcome. Unset means the choice was not made, and falling back to the bundled class stays its documented behaviour. Whitespace-only means a choice was made and is garbage, in the field that decides where TLS terminates: resolving it quietly would take a tenant the operator meant to put behind an edge terminator and publish it directly, with a real certificate on a real address. Both the platform default and the tenant's own choice now refuse it by name. The kind check beside that refusal is part of the same fix, not a tidy up. Through Helm's values path an unquoted numeric scalar arrives as a float64, and the whitespace check compares it against a string, so `className: 123` dies at that comparison — one line before the trim — with an error naming neither the key nor the file. Refusing whitespace without checking the kind first would therefore have made the numeric case worse than it was. `kindIs "string"` is the right test because it never has to name the type that actually arrived. Also correct a cleanup log line: the wildcard Certificate is deleted for every mode that is not DNS-01, so naming HTTP-01 in that message is wrong for existingSecret and for edge alike. And state the listener name invariant plainly: the cap is 253, not the 63 of a DNS label, and the longest name the builders produce is 84.

Two of the three readers of the platform class name refuse a value that is non-empty before trimming and empty after; the ClusterIssuer template still resolved it to the bundled class and carried on. That reader is the one deciding whether the ACME solver keeps its sectionName pin, so a blank value landing there aims every HTTP-01 challenge in the cluster at a listener shape the Gateway may not have. Unreachable while the platform refuses it at the writer, which is a statement about today rather than about the code. Also correct two documentation claims. The class page said an empty tenantSelectableClasses means tenants cannot choose at all, and then that a tenant may always name the platform default — both cannot hold, and the second is the behaviour. The chart README's edge note pointed at "the paragraph below" while meaning the port-80 rule stated further down inside the same paragraph.

The pages describing what an edge-terminated publishing class costs said the platform's TLSRoute endpoints stop being served, without saying when they exist at all. Each of the three renders only where gateway.enabled is on and its own name is still in publishing.exposedServices, so at the default gateway.enabled: false there is no route and no cost. Stated unconditionally, the paragraph describes a consequence that is empty for most readers and real for some, with nothing telling them which they are. Give the wildcard Certificate cleanup a comment that matches its branch, too. It runs for every mode that is not DNS-01, and said HTTP-01; existingSecret references an operator-supplied Secret and mints no Certificate of its own, and edge mints nothing at all.

The type guard on gateway.className sat behind `default ""`, and sprig's `default` fires on any falsy value — so `0` and `false` were laundered into the empty string and resolved to the bundled class before the kind check existed. Only a non-falsy non-string ever reached it. The guard covered the loudest bad input and missed the two quietest, in the value that decides where TLS terminates, where a silent substitution is the failure the guard was added to prevent. Read the value first, skip the checks only when the key is genuinely absent, and normalise afterwards. Unset keeps the documented fallback to the bundled class; anything present and not a string refuses by name, in the same form the two class lists beside it already use. The order of a guard's steps is part of the guard: a normalisation placed ahead of a check destroys the evidence the check needs, and the result still looks like a guard from every angle except the inputs it was meant to catch. The two new cases pin the order rather than the presence — they pass under a guard that merely exists and fail under one that runs too late.

LGTM with notes. Carefully designed and well covered. Tenant isolation holds: the allowlist is enforced fail-closed in the chart on the tenant-writable tenant.spec.gatewayClass, an inheriting tenant ignores the field (the gateway HR is gated on tenant.gatewayEffective), and a separate publishing-tenant guard closes the cluster-wide ACME gap. Upgrade is safe: new _cluster keys default softly when absent, existing tenants stay on cilium/http01, the non-edge listener set is unchanged, certMode extends reversibly, RBAC on tenantgateways is already covered, and generated artifacts are committed. Local tests green (helm unittest gateway 46 / platform 145 / tenant 45, Go tests for both controllers).
Non-blocking:
- [MINOR] Switching an existing
http01tenant toedgecan leave stale route conditions (a route may keepAccepted=True), and anexistingSecrettoedgeswitch has a brief window where an HTTPS listener references an already-pruned Secret. Both affect only the switching tenant, are transient, and are documented as inherent to the two-controller design. - [Caveat] The per-tenant selection path is covered by unit tests only. Recommend a
cozystack-pr-testrun switching a tenant's class on a live dev cluster before merge, since class reprogramming is render-blind to static review.Gateway.spec.gatewayClassNameis not immutable, so the switch is not apiserver-rejected.

What this PR does
Lets a tenant publish through a GatewayClass whose provider terminates TLS upstream of the Gateway, and gives the platform the two knobs that bound the choice. The first consumer is the Cloudflare Tunnel controller from #3858, which ends TLS at the Cloudflare edge and reaches the Gateway over the tunnel, but nothing here is tunnel-specific.
Until now every cert mode rendered HTTPS listeners with
certificateRefsand tied the TenantGateway'sReadyto their issuance. On such a class the platform issued origin certificates nobody serves, and where ACME could not complete, the tenant'sgatewayrelease never became Ready at all.Who picks the class. The platform names a default in
gateway.classNameand the set a tenant may choose from ingateway.tenantSelectableClasses; a tenant picks its own withtenant.spec.gatewayClass. That set is an allowlist rather than free choice because Tenant is a tenant-writable object while GatewayClass is cluster-scoped: without it a tenant could attach its Gateway to a class an admin keeps for internal-only traffic. Naming anything outside the set fails that tenant's own gateway release with a message listing what is allowed, and reaches no other tenant.Where TLS ends. That is a property of the class, not of the tenant, so it is declared once in
gateway.edgeTerminatedClasses, and whichever class a tenant lands on decides itscertMode. The two therefore cannot be configured out of step: a tenant on a tunnel class cannot keep issuing origin certificates because a separate switch still says otherwise.In
edgethe controller renders the apex, its wildcard and every inheriting child apex as plain HTTP listeners carrying the same label-basedallowedRoutesas the HTTPS listeners of the other modes, so app HTTPRoutes attach by hostname unchanged. It mints no Issuer, no Certificate and no http-to-https redirect route, and skips the TLS-passthrough listeners an HTTP-only edge cannot serve, which leaves the tenant Kubernetes API, VM export and CDI upload endpoints unpublished through that Gateway. Moving a tenant into the mode removes the ACME objects it owned, and the cluster-wide ACME solver drops itssectionName: httppin when the publishing Gateway itself sits on such a class. Pointinggateway.classNameat an edge class is therefore a supported topology — the whole platform behind one terminator — and its cost is that those three endpoints stop being published for the publishing tenant rather than for one tenant among many. Nothing refuses it, because refusing it would forbid the topology;docs/gateway-classes.mdstates the cost where an operator will meet it.Two consequences worth stating plainly. The wildcard-secret controller replicated the operator's TLS Secret, private key included, into every namespace owning a termination point, and a Gateway owner counted as one; a Gateway on an edge class does not, so that tenant's replica is pruned while its neighbours keep theirs. And listing a class as edge-terminated is a claim nothing validates: name the bundled
ciliumand its Gateways publish every app hostname over plain HTTP on a public address. A hardfailthere would forbid a legitimate topology, a Cilium Gateway behind an external terminator, so it is stated in the platform values, the chart README and the CRD field description instead.Documentation.
docs/gateway-classes.mdis the operator-facing page for the whole surface: the three platform values and what each bounds, what a tenant writes to pick a class, howcertModeis derived and in what precedence, what moving a tenant between classes does to its Issuer, its Certificates, the TLS Secrets those leave behind, the redirect route and the wildcard replica, and what each way of getting the names wrong actually looks like — a class name matching nothing installed renders fine and never programs, a misspelling inedgeTerminatedClassessilently leaves the tenant issuing certificates, a default moved out from under a tenant that pinned the old name fails that tenant's release. The chart README keeps the per-mode reference and gains the one constraint it had not stated: the publishing tenant cannot select a class that terminates TLS differently from the platform default, because the cluster-wide ACME issuers derive their solver pin from that default alone.Verified on a v1.6.0-rc.2 dev cluster (Talos, k8s 1.36, cilium 1.19.5) by building the controller from this branch: the CRD enum gained
edge, the Gateway came up withedge/edge-apex/edge-child-*HTTP listeners and nothing else, no Issuer, no Certificate, no redirect route, and the LoadBalancer Service exposed 80/TCP only. That run also caught a defect no unit test could. The first implementation kept the hostname-less:80listener at index 0, and on cilium 1.19.5CheckGatewayAllowedForNamespaceis first-listener-wins (cilium#42159, fixed in 1.19.6), so an inheriting tenant's HTTPRoute came backNotAllowedByListenerseven though a later listener admitted it. Dropping that listener, which in edge mode carries neither ACME nor the redirect, flipped the route toAccepted=Trueand removed a catch-all at the same time.The live check predates the redesign to per-tenant classes, so it exercised the mode rather than the selection path; the selection is covered by unit tests across the four charts and both controllers.
