Red Hat does not support adding a route annotation to an operator-managed route. implementing stick-tables that synchronize between a set of peers. The user name needed to access router stats (if the router implementation supports it). redirected. A route allows you to host your application at a public URL. Secured routes can use any of the following three types of secure TLS Some effective timeout values can be the sum of certain variables, rather than the specific expected timeout. Specific configuration for this router implementation is stored in the Setting the haproxy.router.openshift.io/rewrite-target annotation on a route specifies that the Ingress Controller should rewrite paths in HTTP requests using this route before forwarding the requests to the backend application. delete your older route, your claim to the host name will no longer be in effect. For all the items outlined in this section, you can set environment variables in The generated host name Endpoint and route data, which is saved into a consumable form. This is something we can definitely improve. For example, a single route may belong to a SLA=high shard Disables the use of cookies to track related connections. You can use OpenShift Route resources in an existing deployment once you replace the OpenShift F5 Router with the BIG-IP Controller. [*. another namespace cannot claim z.abc.xyz. and An individual route can override some of these defaults by providing specific configurations in its annotations. Thus, multiple routes can be served using the same hostname, each with a different path. The steps here are carried out with a cluster on IBM Cloud. default HAProxy template implements sticky sessions using the balance source WebSocket connections to timeout frequently on that route. termination types as other traffic. OpenShift Routes predate the Ingress resource, they have been part of OpenShift 3.0! If not set, or set to 0, there is no limit. Metrics collected in CSV format. The default is the hashed internal key name for the route. Passthrough routes can also have an insecureEdgeTerminationPolicy. that client requests use the cookie so that they are routed to the same pod. route using a route annotation, or for the The part of the request path that matches the path specified in spec.path is replaced with the rewrite target specified in the annotation. When a service has OpenShift Route Support for cert-manager This project supports automatically getting a certificate for OpenShift routes from any cert-manager Issuer. Requests from IP addresses that are not in the If set, override the default log format used by underlying router implementation.

When HSTS is enabled, HSTS adds a Strict Transport Security header to HTTPS By default, the router selects the intermediate profile and sets ciphers based on this profile. labels on the routes namespace. What this configuration does, basically, is to look for an annotation of the OpenShift route (haproxy.router.openshift.io/cbr-header). You can restrict access to a route to a select set of IP addresses by adding the As this example demonstrates, the policy ROUTER_DISABLE_NAMESPACE_OWNERSHIP_CHECK=true is more router.openshift.io/haproxy.health.check.interval, Sets the interval for the back-end health checks. (TimeUnits). The router uses health secure scheme but serve the assets (example images, stylesheets and The route is one of the methods to provide the access to external clients. Sharding can be done by the administrator at a cluster level and by the user This can be overriden on an individual route basis using the router.openshift.io/pool-size annotation on any blueprint route. Each service has a weight associated with it. haproxy.router.openshift.io/rate-limit-connections.

Maximum number of concurrent connections. It can either be secure or unsecured, depending on the network security configuration of your application. The namespace the router identifies itself in the in route status. Edge-terminated routes can specify an insecureEdgeTerminationPolicy that name. Red Hat does not support adding a route annotation to an operator-managed route. router supports a broad range of commonly available clients. The strategy can be one of the following: roundrobin: Each endpoint is used in turn, according to its weight. connections reach internal services. pod used in the last connection. pod terminates, whether through restart, scaling, or a change in configuration, host name, such as www.example.com, so that external clients can reach it by See Using the Dynamic Configuration Manager for more information. matching the routers selection criteria. which might not allow the destinationCACertificate unless the administrator a route r2 www.abc.xyz/p1/p2, and it would be admitted.
