The chart renders ONLY HTTPRoutes with parentRefs: no Gateway, no # class, no Certificate, and no implementation-specific policy object. Class # and certificate sit on the Gateway and its listeners and belong to the # platform (cluster-config), which is what keeps the Gateway implementation # replaceable without touching this chart again. # # TWO ROUTES, not one. The Ingress is a single object with two HOST rules - the # homeserver on ingress.domain at "/", and the delegation nginx on # matrix.delegation.serverUrl at "/.well-known/matrix". An HTTPRoute's # hostnames apply to the whole object, so two hostnames wanting different paths # and different backends must be two objects. (#114 describes this chart as # rendering its Ingresses in a loop over several apps; it does not - that is # freesailarr.) # # ONE THING THIS MODE MAKES EASIER, and it is the awkward part of Matrix # delegation: the server name is usually an apex domain that already serves a # website. Under ingress-nginx two Ingress objects cannot both claim one # hostname - the admission webhook rejects the second - which is why the # delegation rule has to live inside this chart's single Ingress object. # HTTPRoutes attached to the same listener for the same hostname are MERGED by # the implementation, longest match winning, so here the /.well-known/matrix # route can sit beside whatever owns that apex without either side knowing. # # WHAT THIS MODE COSTS, MEASURED ON THE LIVE OBJECT ON 2026-10-12, where the # Ingress carried - all of it OPERATOR-supplied through ingress.annotations, # since this chart sets none of it: # # nginx.ingress.kubernetes.io/proxy-body-size: 50m # nginx.org/client-max-body-size: 50m # nginx.ingress.kubernetes.io/configuration-snippet: | # more_set_headers "X-Forwarded-For $remote_addr"; # more_set_headers "X-Forwarded-Proto $scheme"; # more_set_headers "Host $host:$server_port"; # # 1. THE BODY SIZE IS THE REAL LOSS. Synapse's media repository takes uploads # and its own ceiling is max_upload_size in homeserver.yaml - which this # chart cannot see, because the whole config comes from 1Password through # secrets.configSecretRef. The effective limit is the smaller of the two, # and in this mode the proxy half becomes THE GATEWAY'S default: neither # number anyone can point at is necessarily the one that decides. The # Gateway API has no body-size field, so per decision 2 of #114 this is # documented rather than rebuilt. Set it next to the Gateway, in that # implementation's own object, and set it to match max_upload_size. # (nginx.org/client-max-body-size is the same limit spelled for NGINX Inc's # ingress controller rather than ingress-nginx - a hedge across both - and # it goes for the same reason.) # # 2. THE SNIPPET IS NOT LOAD-BEARING, WHICH TOOK CHECKING. It looks like what # Synapse's x_forwarded setting depends on - client IP for rate limiting, # and federation. It is not: more_set_headers is the OUTPUT-header directive # of headers-more-nginx-module ("Replaces (if any) or adds (if not any) the # specified output headers"), while the request-side directive is # more_set_input_headers. These three headers are therefore added to the # RESPONSE TO THE CLIENT; Synapse never sees them, and what it reads with # x_forwarded: true is the REQUEST's X-Forwarded-For, which ingress-nginx # sets itself. # # So for the migration: not translatable, and not needed. The Gateway API's # ResponseHeaderModifier can set static response headers but knows no nginx # variables ($remote_addr, $scheme, $host), so rebuilding it is impossible # anyway - and pointless. Do NOT re-create it at the Gateway in the belief # that Synapse needs it. # # Stated as what it is: a reading of the directive's documented semantics. # Nothing here observed a Synapse instance with and without the snippet. # # THE GATEWAY-API CRDs MUST BE PRESENT. The chart cannot detect them # (.Capabilities.APIVersions is unreliable at template time) and an HTTPRoute # without them fails at install, so this is a value and not a guess. httpRoute: enabled: false # The Gateway(s) the HOMESERVER route attaches to - a platform object, # usually in another namespace, whose listener must allow this namespace in # allowedRoutes. Entries are the Gateway API's ParentReference (name, and # optionally namespace, sectionName, port, group, kind), passed through # unchanged: # # parentRefs: # - name: public # namespace: gateway # sectionName: https # # REQUIRED while httpRoute.enabled is true - the render aborts on an empty # list, because a route without a parent is created, is valid and routes # nothing, with no event to say so. parentRefs: [] # Empty means [ingress.domain], so the homeserver hostname has one source of # truth. Set explicitly only to publish under a different or an additional # name - which is how a migration from the Ingress runs: the HTTPRoute takes # a second hostname while the Ingress keeps ingress.domain. # # THE DELEGATION HOST IS NOT COVERED BY THIS LIST, deliberately - see below. hostnames: [] delegation: # The delegation route's own parent. Empty falls back to # httpRoute.parentRefs. Worth setting when the SERVER NAME is published by # a different Gateway than the homeserver host, which is the normal case: # the server name is an apex domain somebody else's website usually owns. parentRefs: [] # Empty means [matrix.delegation.serverUrl], and it deliberately does NOT # fall back to httpRoute.hostnames. The server name is a different thing # from the homeserver's hostname - it is what REMOTE homeservers resolve - # and the migration order depends on telling them apart: move the # homeserver host first, confirm it answers, move the server name last. # A chart-global hostname list covering both would erase that distinction. # Set this only when the server name itself has to move. hostnames: []
