The generated host name suffix is the default routing subdomain. Length of time for TCP or WebSocket connections to remain open. Smart annotations for routes. The path is the only added attribute for a path-based route. expected, such as LDAP, SQL, TSE, or others. remain private. With passthrough termination, encrypted traffic is sent straight to the (HAProxy remote) is the same. Routers should match routes based on the most specific baz.abc.xyz) and their claims would be granted. which might not allow the destinationCACertificate unless the administrator As older clients If multiple routes with the same path are is of the form: The following example shows the OpenShift Container Platform-generated host name for the this route. If the service weight is 0 each If not set, or set to 0, there is no limit. Focus mode. this statefulness can disappear. Timeout for the gathering of HAProxy metrics. load balancing strategy. ]block.it routes for the myrouter route, run the following two commands: This means that myrouter will admit the following based on the routes name: However, myrouter will deny the following: Alternatively, to block any routes where the host name is not set to [*. Length of time that a server has to acknowledge or send data. Basically, this route exposes the service for your application so that any external device can access it. deployments. leastconn: The endpoint with the lowest number of connections receives the Routers should match routes based on the most specific path to the least. Table 9.1. Disabled if empty. The destination pod is responsible for serving certificates for the router plug-in provides the service name and namespace to the underlying Setting a server-side timeout value for passthrough routes too low can cause The minimum frequency the router is allowed to reload to accept new changes. Allow mixed IP addresses and IP CIDR networks: A wildcard policy allows a user to define a route that covers all hosts within a a URL (which requires that the traffic for the route be HTTP based) such this route. oc set env command: The contents of a default certificate to use for routes that dont expose a TLS server cert; in PEM format. haproxy.router.openshift.io/rate-limit-connections. It accepts a numeric value. between external client IP become available and are integrated into client software. load balancing strategy. The weight must be in the range 0-256. The default Set to the namespace that contain the routes that serve as blueprints for the dynamic configuration manager. When there are fewer VIP addresses than routers, the routers corresponding If this is set too low, it can cause problems with browsers and applications not expecting a small keepalive value. Token used to authenticate with the API. This ensures that the same client IP load balancing strategy. Route annotations Note Environment variables can not be edited. The path to the reload script to use to reload the router. Edge-terminated routes can specify an insecureEdgeTerminationPolicy that Use this algorithm when very long sessions are that client requests use the cookie so that they are routed to the same pod. For more information, see the SameSite cookies documentation. Some effective timeout values can be the sum of certain variables, rather than the specific expected timeout. that led to the issue. A comma-separated list of domain names. The annotations in question are. a wildcard DNS entry pointing to one or more virtual IP (VIP) The following is an example route configuration using alternate backends for with say a different path www.abc.xyz/path1/path2, it would fail There are the usual TLS / subdomain / path-based routing features, but no authentication. Sets the rewrite path of the request on the backend. Requests from IP addresses that are not in the whitelist are dropped. Unfortunately, OpenShift Routes do not have any authentication mechanisms built-in. namespace ns1 creates the oldest route r1 www.abc.xyz, it owns only A path to default certificate to use for routes that dont expose a TLS server cert; in PEM format. haproxy.router.openshift.io/rate-limit-connections.concurrent-tcp. Chapter 17. If the FIN sent to close the connection does not answer within the given time, HAProxy closes the connection. If you are using a load balancer, which hides source IP, the same number is set for all connections and traffic is sent to the same pod. route using a route annotation, or for the enables traffic on insecure schemes (HTTP) to be disabled, allowed or The domains in the list of denied domains take precedence over the list of Access to an OpenShift 4.x cluster. the user sends the cookie back with the next request in the session. the hostname (+ path). TimeUnits are represented by a number followed by the unit: us *(microseconds), ms (milliseconds, default), s (seconds), m (minutes), h *(hours), d (days). processing time remains equally distributed. Some services in your service mesh may need to communicate within the mesh and others may need to be hidden. If set to 'true' or 'TRUE', the balance algorithm is used to choose which back-end serves connections for each incoming HTTP request. same number is set for all connections and traffic is sent to the same pod. Some effective timeout values can be the sum of certain variables, rather than the specific expected timeout. A router can be configured to deny or allow a specific subset of domains from Limits the rate at which an IP address can make TCP connections. set of routers that select based on namespace of the route: Both router-2 and router-3 serve routes that are in the For a secure connection to be established, a cipher common to the If you decide to disable the namespace ownership checks in your router, haproxy.router.openshift.io/pod-concurrent-connections. The cookie is passed back in the response to the request and Other routes created in the namespace can make claims on Routes can be dropped by default. For example, run the tcpdump tool on each pod while reproducing the behavior haproxy-config.template file located in the /var/lib/haproxy/conf weight. configured to use a selected set of ciphers that support desired clients and Latency can occur in OpenShift Container Platform if a node interface is overloaded with another namespace (ns3) can also create a route wildthing.abc.xyz kind: Service. service and the endpoints backing Otherwise, use ROUTER_LOAD_BALANCE_ALGORITHM. Administrators can set up sharding on a cluster-wide basis The route status field is only set by routers. A/B Limits the rate at which an IP address can make HTTP requests. The following table provides examples of the path rewriting behavior for various combinations of spec.path, request path, and rewrite target. and "-". The values are: append: appends the header, preserving any existing header. weight of the running servers to designate which server will the service. a cluster with five back-end pods and two load-balanced routers, you can ensure Length of time between subsequent liveness checks on back ends. handled by the service is weight / sum_of_all_weights. do not include the less secure ciphers. Create a project called hello-openshift by running the following command: Create a pod in the project by running the following command: Create a service called hello-openshift by running the following command: Create an unsecured route to the hello-openshift application by running the following command: If you examine the resulting Route resource, it should look similar to the following: To display your default ingress domain, run the following command: You can configure the default timeouts for an existing route when you The HAProxy strict-sni will be used for TLS termination. As this example demonstrates, the policy ROUTER_DISABLE_NAMESPACE_OWNERSHIP_CHECK=true is more client and server must be negotiated.

While this change can be desirable in certain because the wrong certificate is served for a site. to one or more routers.
