(This section uses \"set of Listeners\" rather than \"Listeners - in a single Gateway\" because implementations MAY merge configuration - from multiple Gateways onto a single data plane, and these rules - _also_ apply in that case). \n Practically, this means that each - listener in a set MUST have a unique combination of Port, Protocol, - and, if supported by the protocol, Hostname. \n Some combinations - of port, protocol, and TLS settings are considered Core support - and MUST be supported by implementations based on their targeted - conformance profile: \n HTTP Profile \n 1. HTTPRoute, Port: 80, - Protocol: HTTP 2. HTTPRoute, Port: 443, Protocol: HTTPS, TLS Mode: - Terminate, TLS keypair provided \n TLS Profile \n 1. TLSRoute, Port: - 443, Protocol: TLS, TLS Mode: Passthrough \n \"Distinct\" Listeners - have the following property: \n The implementation can match inbound - requests to a single distinct Listener. When multiple Listeners - share values for fields (for example, two Listeners with the same - Port value), the implementation can match requests to only one of - the Listeners using other Listener fields. \n For example, the following - Listener scenarios are distinct: \n 1. Multiple Listeners with the - same Port that all use the \"HTTP\" Protocol that all have unique - Hostname values. 2. Multiple Listeners with the same Port that use - either the \"HTTPS\" or \"TLS\" Protocol that all have unique Hostname - values. 3. A mixture of \"TCP\" and \"UDP\" Protocol Listeners, - where no Listener with the same Protocol has the same Port value. - \n Some fields in the Listener struct have possible values that - affect whether the Listener is distinct. Hostname is particularly - relevant for HTTP or HTTPS protocols. \n When using the Hostname - value to select between same-Port, same-Protocol Listeners, the - Hostname value must be different on each Listener for the Listener - to be distinct. \n When the Listeners are distinct based on Hostname, - inbound request hostnames MUST match from the most specific to least - specific Hostname values to choose the correct Listener and its - associated set of Routes. \n Exact matches must be processed before - wildcard matches, and wildcard matches must be processed before - fallback (empty Hostname value) matches. For example, `\"foo.example.com\"` - takes precedence over `\"*.example.com\"`, and `\"*.example.com\"` - takes precedence over `\"\"`. \n Additionally, if there are multiple - wildcard entries, more specific wildcard entries must be processed - before less specific wildcard entries. For example, `\"*.foo.example.com\"` - takes precedence over `\"*.example.com\"`. The precise definition - here is that the higher the number of dots in the hostname to the - right of the wildcard character, the higher the precedence. \n The - wildcard character will match any number of characters _and dots_ - to the left, however, so `\"*.example.com\"` will match both `\"foo.bar.example.com\"` - _and_ `\"bar.example.com\"`. \n If a set of Listeners contains Listeners - that are not distinct, then those Listeners are Conflicted, and - the implementation MUST set the \"Conflicted\" condition in the - Listener Status to \"True\". \n Implementations MAY choose to accept - a Gateway with some Conflicted Listeners only if they only accept - the partial Listener set that contains no Conflicted Listeners. - To put this another way, implementations may accept a partial Listener - set only if they throw out *all* the conflicting Listeners. No picking - one of the conflicting listeners as the winner. This also means - that the Gateway must have at least one non-conflicting Listener - in this case, otherwise it violates the requirement that at least - one Listener must be present. \n The implementation MUST set a \"ListenersNotValid\" - condition on the Gateway Status when the Gateway contains Conflicted - Listeners whether or not they accept the Gateway. That Condition - SHOULD clearly indicate in the Message which Listeners are conflicted, - and which are Accepted. Additionally, the Listener status for those - listeners SHOULD indicate which Listeners are conflicted and not - Accepted. \n A Gateway's Listeners are considered \"compatible\" - if: \n 1. They are distinct. 2. The implementation can serve them - in compliance with the Addresses requirement that all Listeners - are available on all assigned addresses. \n Compatible combinations - in Extended support are expected to vary across implementations. - A combination that is compatible for one implementation may not - be compatible for another. \n For example, an implementation that - cannot serve both TCP and UDP listeners on the same address, or - cannot mix HTTPS and generic TLS listens on the same port would - not consider those cases compatible, even though they are distinct. - \n Note that requests SHOULD match at most one Listener. For example, - if Listeners are defined for \"foo.example.com\" and \"*.example.com\", - a request to \"foo.example.com\" SHOULD only be routed using routes - attached to the \"foo.example.com\" Listener (and not the \"*.example.com\" - Listener). This concept is known as \"Listener Isolation\". Implementations - that do not support Listener Isolation MUST clearly document this. - \n Implementations MAY merge separate Gateways onto a single set - of Addresses if all Listeners across all Gateways are compatible. - \n Support: Core" - items: - description: Listener embodies the concept of a logical endpoint - where a Gateway accepts network connections. - properties: - allowedRoutes: - default: - namespaces: - from: Same - description: "AllowedRoutes defines the types of routes that - MAY be attached to a Listener and the trusted namespaces where - those Route resources MAY be present. \n Although a client - request may match multiple route rules, only one rule may - ultimately receive the request.

At - least one Listener MUST be specified. \n Each Listener in a set - of Listeners (for example, in a single Gateway) MUST be _distinct_, - in that a traffic flow MUST be able to be assigned to exactly one - listener. (This section uses \"set of Listeners\" rather than \"Listeners - in a single Gateway\" because implementations MAY merge configuration - from multiple Gateways onto a single data plane, and these rules - _also_ apply in that case). \n Practically, this means that each - listener in a set MUST have a unique combination of Port, Protocol, - and, if supported by the protocol, Hostname. \n Some combinations - of port, protocol, and TLS settings are considered Core support - and MUST be supported by implementations based on their targeted - conformance profile: \n HTTP Profile \n 1. HTTPRoute, Port: 80, - Protocol: HTTP 2. HTTPRoute, Port: 443, Protocol: HTTPS, TLS Mode: - Terminate, TLS keypair provided \n TLS Profile \n 1. TLSRoute, Port: - 443, Protocol: TLS, TLS Mode: Passthrough \n \"Distinct\" Listeners - have the following property: \n The implementation can match inbound - requests to a single distinct Listener. When multiple Listeners - share values for fields (for example, two Listeners with the same - Port value), the implementation can match requests to only one of - the Listeners using other Listener fields. \n For example, the following - Listener scenarios are distinct: \n 1. Multiple Listeners with the - same Port that all use the \"HTTP\" Protocol that all have unique - Hostname values. 2. Multiple Listeners with the same Port that use - either the \"HTTPS\" or \"TLS\" Protocol that all have unique Hostname - values. 3. A mixture of \"TCP\" and \"UDP\" Protocol Listeners, - where no Listener with the same Protocol has the same Port value. - \n Some fields in the Listener struct have possible values that - affect whether the Listener is distinct. Hostname is particularly - relevant for HTTP or HTTPS protocols. \n When using the Hostname - value to select between same-Port, same-Protocol Listeners, the - Hostname value must be different on each Listener for the Listener - to be distinct. \n When the Listeners are distinct based on Hostname, - inbound request hostnames MUST match from the most specific to least - specific Hostname values to choose the correct Listener and its - associated set of Routes. \n Exact matches must be processed before - wildcard matches, and wildcard matches must be processed before - fallback (empty Hostname value) matches. For example, `\"foo.example.com\"` - takes precedence over `\"*.example.com\"`, and `\"*.example.com\"` - takes precedence over `\"\"`. \n Additionally, if there are multiple - wildcard entries, more specific wildcard entries must be processed - before less specific wildcard entries. For example, `\"*.foo.example.com\"` - takes precedence over `\"*.example.com\"`. The precise definition - here is that the higher the number of dots in the hostname to the - right of the wildcard character, the higher the precedence. \n The - wildcard character will match any number of characters _and dots_ - to the left, however, so `\"*.example.com\"` will match both `\"foo.bar.example.com\"` - _and_ `\"bar.example.com\"`. \n If a set of Listeners contains Listeners - that are not distinct, then those Listeners are Conflicted, and - the implementation MUST set the \"Conflicted\" condition in the - Listener Status to \"True\". \n Implementations MAY choose to accept - a Gateway with some Conflicted Listeners only if they only accept - the partial Listener set that contains no Conflicted Listeners. - To put this another way, implementations may accept a partial Listener - set only if they throw out *all* the conflicting Listeners. No picking - one of the conflicting listeners as the winner. This also means - that the Gateway must have at least one non-conflicting Listener - in this case, otherwise it violates the requirement that at least - one Listener must be present. \n The implementation MUST set a \"ListenersNotValid\" - condition on the Gateway Status when the Gateway contains Conflicted - Listeners whether or not they accept the Gateway. That Condition - SHOULD clearly indicate in the Message which Listeners are conflicted, - and which are Accepted. Additionally, the Listener status for those - listeners SHOULD indicate which Listeners are conflicted and not - Accepted. \n A Gateway's Listeners are considered \"compatible\" - if: \n 1. They are distinct. 2. The implementation can serve them - in compliance with the Addresses requirement that all Listeners - are available on all assigned addresses. \n Compatible combinations - in Extended support are expected to vary across implementations. - A combination that is compatible for one implementation may not - be compatible for another. \n For example, an implementation that - cannot serve both TCP and UDP listeners on the same address, or - cannot mix HTTPS and generic TLS listens on the same port would - not consider those cases compatible, even though they are distinct. - \n Note that requests SHOULD match at most one Listener. For example, - if Listeners are defined for \"foo.example.com\" and \"*.example.com\", - a request to \"foo.example.com\" SHOULD only be routed using routes - attached to the \"foo.example.com\" Listener (and not the \"*.example.com\" - Listener).

For example, a Route with - a creation timestamp of \"2020-09-08 01:02:03\" is given precedence - over a Route with a creation timestamp of \"2020-09-08 01:02:04\". - * If everything else is equivalent, the Route appearing first - in alphabetical order (namespace/name) should be given precedence. - For example, foo/bar is given precedence over foo/baz. \n - All valid rules within a Route attached to this Listener should - be implemented.

For example, `"foo.example.com"` takes precedence over + `"*.example.com"`, and `"*.example.com"` takes precedence over `""`. + + + Additionally, if there are multiple wildcard entries, more specific + wildcard entries must be processed before less specific wildcard entries. + For example, `"*.foo.example.com"` takes precedence over `"*.example.com"`. + The precise definition here is that the higher the number of dots in the + hostname to the right of the wildcard character, the higher the precedence. + + + The wildcard character will match any number of characters _and dots_ to + the left, however, so `"*.example.com"` will match both + `"foo.bar.example.com"` _and_ `"bar.example.com"`. + + + If a set of Listeners contains Listeners that are not distinct, then those + Listeners are Conflicted, and the implementation MUST set the "Conflicted" + condition in the Listener Status to "True". + + + Implementations MAY choose to accept a Gateway with some Conflicted + Listeners only if they only accept the partial Listener set that contains + no Conflicted Listeners.

That Condition SHOULD clearly + indicate in the Message which Listeners are conflicted, and which are + Accepted. Additionally, the Listener status for those listeners SHOULD + indicate which Listeners are conflicted and not Accepted. + + + A Gateway's Listeners are considered "compatible" if: + + + 1.
