Route [route.openshift.io/v1]
Description
A route allows developers to expose services through an HTTP(S) aware load balancing and proxy layer via a public DNS entry. The route may further specify TLS options and a certificate, or specify a public CNAME that the router should also accept for HTTP and HTTPS traffic. An administrator typically configures their router to be visible outside the cluster firewall, and may also add additional security, caching, or traffic controls on the service content. Routers usually talk directly to the service endpoints.
Once a route is created, the host
field may not be changed. Generally, routers use the oldest route with a given host when resolving conflicts.
Routers are subject to additional customization and may support additional controls via the annotations field.
Because administrators may configure multiple routers, the route status field is used to return information to clients about the names and states of the route under each router. If a client chooses a duplicate name, for instance, the route status conditions are used to indicate the route cannot be chosen.
To enable HTTP/2 ALPN on a route it requires a custom (non-wildcard) certificate. This prevents connection coalescing by clients, notably web browsers. We do not support HTTP/2 ALPN on routes that use the default certificate because of the risk of connection re-use/coalescing. Routes that do not have their own custom certificate will not be HTTP/2 ALPN-enabled on either the frontend or the backend.

The tls
field is optional and allows specific certificates or behavior for the route. Routers typically configure a default certificate on a wildcard domain to terminate routes without explicit certificates, but custom hostnames usually must choose passthrough (send traffic directly to the backend via the TLS Server-Name- Indication field) or provide a certificate.

An ingress controller may choose to ignore this suggested name, in which case the controller will report the assigned name in the status.ingress array or refuse to admit the route. If this value is set and the server does not support this field host will be populated automatically. Otherwise host is left empty. The field may have multiple parts separated by a dot, but not all ingress controllers may honor the request. This field may not be changed after creation except by a user with the update routes/custom-host permission. Example: subdomain |

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.
