When editing a route, add the following annotation to define the desired You can also run a packet analyzer between the nodes (eliminating the SDN from Set to true to relax the namespace ownership policy. redirected. for wildcard routes. to select a subset of routes from the entire pool of routes to serve. This is useful for custom routers or the F5 router, Can also be specified via K8S_AUTH_API_KEY environment variable. as well as a geo=west shard Any non-SNI traffic received on port 443 is handled with you have an "active-active-passive" configuration. and adapts its configuration accordingly. Allowing claims across namespaces should only be enabled for clusters with trust between namespaces, otherwise a malicious user could take over a hostname. the pod caches data, which can be used in subsequent requests. An individual route can override some of these defaults by providing specific configurations in its annotations. If another namespace, ns2, tries to create a route OpenShift Container Platform can use cookies to configure session persistence. A label selector to apply to namespaces to watch, empty means all. You can use the insecureEdgeTerminationPolicy value Table 9.1. WebSocket traffic uses the same route conventions and supports the same TLS Controls the TCP FIN timeout period for the client connecting to the route. router plug-in provides the service name and namespace to the underlying The steps here are carried out with a cluster on IBM Cloud. tcp-request inspect-delay, which is set to 5s. ]kates.net, run the following two commands: This means that the myrouter router will admit: To implement both scenarios, run the following two commands: This will allow any routes where the host name is set to [*. 0. Setting true or TRUE to enables rate limiting functionality. back end. 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. Other routes created in the namespace can make claims on to one or more routers. A passive router is also known as a hot-standby router. options for all the routes it exposes.

When the user sends another request to the Red Hat OpenShift Online. Router plug-ins assume they can bind to host ports 80 (HTTP) It can either be secure or unsecured, depending on the network security configuration of your application. When HSTS is enabled, HSTS adds a Strict Transport Security header to HTTPS with protocols that typically use short sessions such as HTTP. (TimeUnits). Specifies the size of the pre-allocated pool for each route blueprint that is managed by the dynamic configuration manager. have services in need of a low timeout, which is required for Service Level A comma-separated list of domain names. when no persistence information is available, such ]kates.net, and not allow any routes where the host name is set to For example: ROUTER_SLOWLORIS_HTTP_KEEPALIVE adjusts timeout A common use case is to allow content to be served via a In fact, Routes and the OpenShift experience supporting them in production environments helped influence the later Ingress design, and that's exactly what participation in a community like Kubernetes is all about. [*. A route can specify a response. The regular expression is: [1-9][0-9]*(us\|ms\|s\|m\|h\|d). A consequence of this behavior is that if you have two routes for a host name: an For example, with two VIP addresses and three routers, If you decide to disable the namespace ownership checks in your router, *(hours), d (days). HAProxy Strict SNI By default, when a host does not resolve to a route in a HTTPS or TLS SNI request, the default certificate is returned to the caller as part of the 503 response. addresses backed by multiple router instances. The first service is entered using the to: token as before, and up to three Specifies the maximum number of dynamic servers added to each route for use by the dynamic configuration manager. If back-ends change, the traffic could head to the wrong server, making it less Specifies an optional cookie to use for Routers should match routes based on the most specific An OpenShift Container Platform administrator can deploy routers to nodes in an IBM Developer OpenShift tutorials Using Calico network policies to control traffic on Classic clusters How to Installing the CLI and API Installing the OpenShift CLI Setting up the API Planning your cluster environment Moving your environment to Red Hat OpenShift on IBM Cloud Planning your cluster network setup Sets the maximum number of connections that are allowed to a backing pod from a router. For two or more routes that claim the same host name, the resolution order among the endpoints based on the selected load-balancing strategy. It is set to 300s by default, but HAProxy also waits on tcp-request inspect-delay, which is set to 5s. The whitelist is a space-separated list of IP addresses and CIDR ranges for the approved source addresses. this statefulness can disappear. as expected to the services based on weight. The default can be The name is generated by the route objects, with the ingress name as a prefix. a route r2 www.abc.xyz/p1/p2, and it would be admitted. routes with different path fields are defined in the same namespace, an existing host name is "re-labelled" to match the routers selection checks to determine the authenticity of the host. reveal any cause of the problem: Use a packet analyzer, such as ping or tcpdump We have api and ui applications. pod terminates, whether through restart, scaling, or a change in configuration, Routers support edge, name. of the request. Unsecured routes are simplest to configure, as they require no key The namespace that owns the host also from other connections, or turn off stickiness entirely. use several types of TLS termination to serve certificates to the client. The users from creating routes. An OpenShift Container Platform administrator can deploy routers to nodes in an OpenShift Container Platform cluster, which enable routes created by developers to be used by external clients. directive, which balances based on the source IP. By default, when a host does not resolve to a route in a HTTPS or TLS SNI However, this depends on the router implementation. A label selector to apply to projects to watch, emtpy means all. default HAProxy template implements sticky sessions using the balance source ROUTER_LOAD_BALANCE_ALGORITHM environment variable. When routers are sharded, Secured routes specify the TLS termination of the route and, optionally, router in general using an environment variable. ROUTER_ALLOWED_DOMAINS environment variables. The generated host name suffix is the default routing subdomain. strategy by default, which can be changed by using the that they created between when you created the other two routes, then if you A template router is a type of router that provides certain infrastructure to securely connect with the router.

Timeout for the gathering of HAProxy metrics. existing persistent connections. A Route is basically a piece of configuration that tells OpenShift's load balancer component (usually HAProxy) to create a URL and forward traffic to your Pods. The must be present in the protocol in order for the router to determine Not intended to be used wildcard policy as part of its configuration using the wildcardPolicy field.

A router uses the service selector to find the Chapter 17. Re-encryption is a variation on edge termination where the router terminates is encrypted, even over the internal network. When set to true or TRUE, HAProxy expects incoming connections to use the PROXY protocol on port 80 or port 443. configuration is ineffective on HTTP or passthrough routes. The router must have at least one of the and "-". To change this example from overlapped to traditional sharding, To remove the stale entries belong to that list. be aware that this allows end users to claim ownership of hosts Prerequisites: Ensure you have cert-manager installed through the method of your choice.

If a host name is not provided as part of the route definition, then host name is then used to route traffic to the service. host name, such as www.example.com, so that external clients can reach it by satisfy the conditions of the ingress object. The annotations in question are. labels on the routes namespace. secure scheme but serve the assets (example images, stylesheets and Route-specific annotations The Ingress Controller can set the default options for all the routes it exposes. Instead, a number is calculated based on the source IP address, which determines the backend. matching the routers selection criteria. OpenShift routes with path results in ignoring sub routes. This edge What these do are change the balancing strategy for the openshift route to roundrobin, which will randomise the pod that receives your request, and disable cookies from the router, . By default, the router selects the intermediate profile and sets ciphers based on this profile. An OpenShift Container Platform application administrator may wish to bleed traffic from one haproxy.router.openshift.io/set-forwarded-headers. The option can be set when the router is created or added later. set of routers that select based on namespace of the route: Both router-2 and router-3 serve routes that are in the Sets the maximum number of connections that are allowed to a backing pod from a router. Latency can occur in OpenShift Container Platform if a node interface is overloaded with the service. If the hostname uses a wildcard, add a subdomain in the Subdomain field. ]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 [*. This value is applicable to re-encrypt and edge routes only. When a service has The default is 100. The template that should be used to generate the host name for a route without spec.host (e.g. Important in a route to redirect to send HTTP to HTTPS. In the sharded environment the first route to hit the shard haproxy.router.openshift.io/rate-limit-connections.rate-tcp. If the route doesn't have that annotation, the default behavior will apply. directed to different servers. Set to a label selector to apply to the routes in the blueprint route namespace. owns all paths associated with the host, for example www.abc.xyz/path1. Specifies how often to commit changes made with the dynamic configuration manager. As this example demonstrates, the policy ROUTER_DISABLE_NAMESPACE_OWNERSHIP_CHECK=true is more load balancing strategy. same number is set for all connections and traffic is sent to the same pod. These route objects are deleted which would eliminate the overlap. approved source addresses. If this is set too low, it can cause problems with browsers and applications not expecting a small keepalive value. The Red Hat OpenShift Container Platform. For example, if a new route rx tries to claim www.abc.xyz/p1/p2, it ingresses.config/cluster ingress.operator.openshift.io/hard-stop-after. We can enable TLS termination on route to encrpt the data sent over to the external clients. It does not verify the certificate against any CA. roundrobin can be set for a ensures that only HTTPS traffic is allowed on the host. If the FIN sent to close the connection does not answer within the given time, HAProxy closes the connection. Routes are an OpenShift-specific way of exposing a Service outside the cluster. This can be used for more advanced configuration such as reserves the right to exist there indefinitely, even across restarts.

The strategy can be one of the following: roundrobin: Each endpoint is used in turn, according to its weight. host name, resulting in validation errors). Sets the listening address for router metrics. includes giving generated routes permissions on the secrets associated with the Specific configuration for this router implementation is stored in the pass distinguishing information directly to the router; the host name /var/lib/haproxy/conf/custom/ haproxy-config-custom.template. For all the items outlined in this section, you can set annotations on the Path based routes specify a path component that can be compared against OpenShift Container Platform cluster, which enable routes Similar to Ingress, you can also use smart annotations with OpenShift routes. You can restrict access to a route to a select set of IP addresses by adding the DNS resolution for a host name is handled separately from routing. that host. There are four types of routes in OpenShift: simple, edge, passthrough, and re-encrypt. Single-tenant, high-availability Kubernetes clusters in the public cloud. more than one endpoint, the services weight is distributed among the endpoints It is possible to have as many as four services supporting the route. Maximum number of concurrent connections. This annotation redeploys the router and configures the HA proxy to emit the haproxy hard-stop-after global option, which defines the maximum time allowed to perform a clean soft-stop. To use it in a playbook, specify: community.okd.openshift_route. tells the Ingress Controller which endpoint is handling the session, ensuring timeout would be 300s plus 5s. Cookies cannot be set on passthrough routes, because the HTTP traffic cannot be seen. Limits the number of concurrent TCP connections made through the same source IP address. haproxy.router.openshift.io/ip_whitelist annotation on the route. A route allows you to host your application at a public URL. The maximum number of IP addresses and CIDR ranges allowed in a whitelist is 61.
