Ingress [networking.k8s.io/v1]
Ingress is a collection of rules that allow inbound connections to reach the endpoints defined by a backend. An Ingress can be configured to give services externally-reachable urls, load balance traffic, terminate SSL, offer name based virtual hosting etc.
Type
.spec
Description
IngressSpec describes the Ingress the user wishes to exist.
Type
object
Property | Type | Description |
---|---|---|
|
| IngressBackend describes all endpoints for a given service and port. |
|
| IngressClassName is the name of the IngressClass cluster resource. The associated IngressClass defines which controller will implement the resource. This replaces the deprecated |
|
| A list of host rules used to configure the Ingress. If unspecified, or no rule matches, all traffic is sent to the default backend. |
|
| IngressRule represents the rules mapping the paths under a specified host to the related backend services. Incoming requests are first evaluated for a host match, then routed to the backend associated with the matching IngressRuleValue. |
|
| TLS configuration. Currently the Ingress only supports a single TLS port, 443. If multiple members of this list specify different hosts, they will be multiplexed on the same port according to the hostname specified through the SNI TLS extension, if the ingress controller fulfilling the ingress supports SNI. |
|
| IngressTLS describes the transport layer security associated with an Ingress. |

.spec.rules
Description
A list of host rules used to configure the Ingress. If unspecified, or no rule matches, all traffic is sent to the default backend.
Type

|
| Host is the fully qualified domain name of a network host, as defined by RFC 3986. Note the following deviations from the “host” part of the URI as defined in RFC 3986: 1. IPs are not allowed. Currently an IngressRuleValue can only apply to the IP in the Spec of the parent Ingress. 2. The Host can be “precise” which is a domain name without the terminating dot of a network host (e.g. “foo.bar.com”) or “wildcard”, which is a domain name prefixed with a single wildcard label (e.g. “.foo.com”). The wildcard character ‘‘ must appear by itself as the first DNS label and matches only a single label. You cannot have a wildcard label by itself (e.g. Host == “*”). Requests will be matched against the Host field in the following way: 1. If Host is precise, the request matches this rule if the http host header is equal to Host. 2. If Host is a wildcard, then the request matches this rule if the http host header is to equal to the suffix (removing the first label) of the wildcard rule. |
|
| HTTPIngressRuleValue is a list of http selectors pointing to backends. In the example: ; → backend where where parts of the url correspond to RFC 3986, this resource will be used to match against everything after the last ‘/‘ and before the first ‘?’ or ‘#’. |
.spec.rules[].http
Description
HTTPIngressRuleValue is a list of http selectors pointing to backends. In the example: http://<host>/<path>?<searchpart>; → backend where where parts of the url correspond to RFC 3986, this resource will be used to match against everything after the last ‘/‘ and before the first ‘?’ or ‘#’.

backend
Property | Type | Description |
---|---|---|
|
| IngressBackend describes all endpoints for a given service and port. |
|
| Path is matched against the path of an incoming request. Currently it can contain characters disallowed from the conventional “path” part of a URL as defined by RFC 3986. Paths must begin with a ‘/‘. When unspecified, all paths from incoming requests are matched. |
|
| PathType determines the interpretation of the Path matching. PathType can be one of the following values: Exact: Matches the URL path exactly. Prefix: Matches based on a URL path prefix split by ‘/‘. Matching is done on a path element by element basis. A path element refers is the list of labels in the path split by the ‘/‘ separator. A request is a match for path p if every p is an element-wise prefix of p of the request path. Note that if the last element of the path is a substring of the last element in request path, it is not a match (e.g. /foo/bar matches /foo/bar/baz, but does not match /foo/barbaz). * ImplementationSpecific: Interpretation of the Path matching is up to the IngressClass. Implementations can treat this as a separate PathType or treat it identically to Prefix or Exact path types. Implementations are required to support all path types. |

If the SNI host in a listener conflicts with the “Host” header field used by an IngressRule, the SNI host is used for termination and value of the Host header is used for routing. |

|
| allowWatchBookmarks requests watch events with type “BOOKMARK”. Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server’s discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored. If the feature gate WatchBookmarks is not enabled in apiserver, this field is ignored. |
|
| The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the “next key”. This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications. |

This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned. |
