Matcher

Parameters for matching routes to requests received by a Gloo-managed proxy

"prefix": string
"exact": string
"regex": string
"connectMatcher": .matchers.core.gloo.solo.io.Matcher.ConnectMatcher
"caseSensitive": .google.protobuf.BoolValue
"headers": []matchers.core.gloo.solo.io.HeaderMatcher
"queryParameters": []matchers.core.gloo.solo.io.QueryParameterMatcher
"methods": []string
Field Type Description
prefix string If specified, the route is a prefix rule meaning that the prefix must match the beginning of the :path header. Only one of prefix, exact, regex, or connectMatcher can be set.
exact string If specified, the route is an exact path rule meaning that the path must exactly match the :path header once the query string is removed. Only one of exact, prefix, regex, or connectMatcher can be set.
regex string If specified, the route is a regular expression rule meaning that the regex must match the :path header once the query string is removed. The entire path (without the query string) must match the regex. The rule will not match if only a sub-sequence of the :path header matches the regex. The regex grammar is defined here <http://en.cppreference.com/w/cpp/regex/ecmascript>_. Examples:
* The regex /b[io]t matches the path /bit
* The regex /b[io]t matches the path /bot
* The regex /b[io]t does not match the path /bite
* The regex /b[io]t does not match the path /bit/bot

Note that the complexity of the regex is constrained by the regex engine’s “program size” setting. If your regex is too complex, you may need to adjust the regexMaxProgramSize field in the GlooOptions section of your Settings resource (The K8sGatewaydefault is 1024). Only one of regex, prefix, exact, or connectMatcher can be set.
connectMatcher .matchers.core.gloo.solo.io.Matcher.ConnectMatcher If this is used as the matcher, the matcher will only match CONNECT requests. Note that this will not match HTTP/2 upgrade-style CONNECT requests (WebSocket and the like) as they are normalized in Envoy as HTTP/1.1 style upgrades. This is the only way to match CONNECT requests for HTTP/1.1. For HTTP/2, where CONNECT requests may have a path, the path matchers will work if there is a path present. Note that CONNECT support is currently considered alpha in Envoy. Only one of connectMatcher, prefix, exact, or regex can be set.
caseSensitive .google.protobuf.BoolValue Indicates that prefix/path matching should be case sensitive. The default is true.
headers []matchers.core.gloo.solo.io.HeaderMatcher Specifies a set of headers that the route should match on. The router will check the request’s headers against all the specified headers in the route config. A match will happen if all the headers in the route are present in the request with the same values (or based on presence if the value field is not in the config).
queryParameters []matchers.core.gloo.solo.io.QueryParameterMatcher Specifies a set of URL query parameters on which the route should match. The router will check the query string from the path header against all the specified query parameters. If the number of specified query parameters is nonzero, they all must match the path header’s query string for a match to occur.
methods []string HTTP Method/Verb(s) to match on. If none specified, the matcher will ignore the HTTP Method.

ConnectMatcher

Field Type Description

HeaderMatcher

Internally, K8sGateway always uses the HTTP/2 :authority header to represent the HTTP/1 Host header. Thus, if attempting to match on Host, match on :authority instead.

"name": string
"value": string
"regex": bool
"invertMatch": bool
Field Type Description
name string Specifies the name of the header in the request.
value string Specifies the value of the header. If the value is absent a request that has the name header will match, regardless of the header’s value.
regex bool Specifies whether the header value should be treated as regex or not.
invertMatch bool If set to true, the result of the match will be inverted. Defaults to false. Examples: * name=foo, invert_match=true: matches if no header named foo is present * name=foo, value=bar, invert_match=true: matches if no header named foo with value bar is present * name=foo, value=\d{3}, regex=true, invert_match=true: matches if no header named foo with a value consisting of three integers is present.

QueryParameterMatcher

Query parameter matching treats the query string of a request’s :path header as an ampersand-separated list of keys and/or key=value elements.

"name": string
"value": string
"regex": bool
Field Type Description
name string Specifies the name of a key that must be present in the requested path’s query string.
value string Specifies the value of the key. If the value is absent, a request that contains the key in its query string will match, whether the key appears with a value (e.g., “?debug=true”) or not (e.g., “?debug”).
regex bool Specifies whether the query parameter value is a regular expression. Defaults to false. The entire query parameter value (i.e., the part to the right of the equals sign in “key=value”) must match the regex. E.g., the regex “\d+$” will match “123” but not “a123” or “123a”.
