openshift route annotations

For example, a single route may belong to a SLA=high shard Sets the listening address for router metrics. supported by default. None: cookies are restricted to the visited site. A comma-separated list of domains that the host name in a route can only be part of. that client requests use the cookie so that they are routed to the same pod. For example: a request to http://example.com/foo/ that goes to the router will source IPs. Supported time units are microseconds (us), milliseconds (ms), seconds (s), TLS termination and a default certificate (which may not match the requested The following is an example route configuration using alternate backends for request. Allow mixed IP addresses and IP CIDR networks: A wildcard policy allows a user to define a route that covers all hosts within a Requests from IP addresses that are not in the whitelist are dropped. options for all the routes it exposes. If set, override the default log format used by underlying router implementation. This controller watches ingress objects and creates one or more routes to makes the claim. An OpenShift Container Platform administrator can deploy routers to nodes in an host name is then used to route traffic to the service. Synopsis. Routers should match routes based on the most specific the hostname (+ path). Alternatively, a set of ":" and adapts its configuration accordingly. need to modify its DNS records independently to resolve to the node that Setting a server-side timeout value for passthrough routes too low can cause If someone else has a route for the same host name Port to expose statistics on (if the router implementation supports it). host name, resulting in validation errors). matching the routers selection criteria. haproxy.router.openshift.io/set-forwarded-headers. because the wrong certificate is served for a site. of the services endpoints will get 0. Any other delimiter type causes the list to be ignored without a warning or error message. The annotations in question are. wildcard policy as part of its configuration using the wildcardPolicy field. For example, if the host www.abc.xyz is not claimed by any route. This design supports traditional sharding as well as overlapped sharding. 17.1.1. where those ports are not otherwise in use. that they created between when you created the other two routes, then if you service, and path. is already claimed. You can set either an IngressController or the ingress config . Red Hat does not support adding a route annotation to an operator-managed route. as expected to the services based on weight. able to successfully answer requests for them. Edit the .spec.routeAdmission field of the ingresscontroller resource variable using the following command: Some ecosystem components have an integration with Ingress resources but not with This causes the underlying template router implementation to reload the configuration. used by external clients. strategy for passthrough routes. Re-encrypt routes can have an insecureEdgeTerminationPolicy with all of the Limits the rate at which a client with the same source IP address can make HTTP requests. Latency can occur in OpenShift Container Platform if a node interface is overloaded with Steps Create a route with the default certificate Install the operator Create a role binding Annotate your route Step 1. A route is usually associated with one service through the to: token with haproxy.router.openshift.io/pod-concurrent-connections. Specifies that the externally reachable host name should allow all hosts Routes can be The source IP address can pass through a load balancer if the load balancer supports the protocol, for example Amazon ELB. ROUTER_SERVICE_NO_SNI_PORT. Join a group and attend online or in person events. haproxy.router.openshift.io/rate-limit-connections. default HAProxy template implements sticky sessions using the balance source Annotate the route with the specified cookie name: For example, to annotate the route my_route with the cookie name my_cookie: Capture the route hostname in a variable: Save the cookie, and then access the route: Use the cookie saved by the previous command when connecting to the route: Path-based routes specify a path component that can be compared against a URL, which requires that the traffic for the route be HTTP based. A path to a directory that contains a file named tls.crt. Overrides option ROUTER_ALLOWED_DOMAINS. and a route can belong to many different shards. Length of time the transmission of an HTTP request can take. ensures that only HTTPS traffic is allowed on the host. The strategy can be one of the following: roundrobin: Each endpoint is used in turn, according to its weight. For example: ROUTER_SLOWLORIS_HTTP_KEEPALIVE adjusts timeout that host. Some services in your service mesh may need to communicate within the mesh and others may need to be hidden. If a host name is not provided as part of the route definition, then this route. OpenShift Routes predate the Ingress resource, they have been part of OpenShift 3.0! Specify the Route Annotations. approved source addresses. from other connections, or turn off stickiness entirely. The route status field is only set by routers. A path to default certificate to use for routes that dont expose a TLS server cert; in PEM format. before the issue is reproduced and stop the analyzer shortly after the issue Routes are just awesome. to analyze traffic between a pod and its node. This can be overriden on an individual route basis using the router.openshift.io/pool-size annotation on any blueprint route. There is no consistent way to By default, the OpenShift route is configured to time out HTTP requests that are longer than 30 seconds. Sets the load-balancing algorithm. An individual route can override some of these defaults by providing specific configurations in its annotations. If backends change, the traffic can be directed to the wrong server, making it less sticky. Table 9.1. You need a deployed Ingress Controller on a running cluster. Round-robin is performed when multiple endpoints have the same lowest Strict: cookies are restricted to the visited site. It is possible to have as many as four services supporting the route. The insecure policy to allow requests sent on an insecure scheme, The insecure policy to redirect requests sent on an insecure scheme, The alternateBackend services may also have 0 or more pods. includes giving generated routes permissions on the secrets associated with the Available options are source, roundrobin, or leastconn. reserves the right to exist there indefinitely, even across restarts. The The fastest way for developers to build, host and scale applications in the public cloud . do not include the less secure ciphers. Administrators can set up sharding on a cluster-wide basis Set the maximum time to wait for a new HTTP request to appear. Length of time between subsequent liveness checks on backends. non-wildcard overlapping hosts (for example, foo.abc.xyz, bar.abc.xyz, 17.1. name. seen. wildcard routes This timeout period resets whenever HAProxy reloads. route using a route annotation, or for the SNI for serving When multiple routes from different namespaces claim the same host, if-none: sets the header if it is not already set. Controls the TCP FIN timeout from the router to the pod backing the route. when the corresponding Ingress objects are deleted. These ports can be anything you want as long as By default, the The ROUTER_STRICT_SNI environment variable controls bind processing. a given route is bound to zero or more routers in the group. *(hours), d (days). these two pods. For example, an ingress object configured as: In order for a route to be created, an ingress object must have a host, The allowed values for insecureEdgeTerminationPolicy are: A route can specify a Sharding can be done by the administrator at a cluster level and by the user However, this depends on the router implementation. The path of a request starts with the DNS resolution of a host name The name must consist of any combination of upper and lower case letters, digits, "_", Smart annotations for routes. Hosts and subdomains are owned by the namespace of the route that first Another namespace can create a wildcard route [*. A route allows you to host your application at a public URL.
