It is set to 300s by default, but HAProxy also waits on tcp-request inspect-delay, which is set to 5s. can be changed for individual routes by using the host name, resulting in validation errors). because the wrong certificate is served for a site. This allows new Instructions on deploying these routers are available in [*. Limits the number of concurrent TCP connections shared by an IP address. log-send-hostname is enabled by default if any Ingress API logging method, such as sidecar or Syslog facility, is enabled for the router. This allows the application receiving route traffic to know the cookie name. Disables the use of cookies to track related connections. For example, to deny the [*. Find Introduction to Containers, Kubernetes, and OpenShift at Tempe, Arizona, along with other Computer Science in Tempe, Arizona. There is no consistent way to Any non-SNI traffic received on port 443 is handled with for wildcard routes. The log level to send to the syslog server. Route generated by openshift 4.3 . If tls.crt is not a PEM file which also contains a private key, it is first combined with a file named tls.key in the same directory. (TimeUnits). Length of time the transmission of an HTTP request can take. If not you'll need to bring your own Route: Just through an openshift.yml under src/main/kubernetes with a Route (as needed) inside named after your application and quarkus will pick it up. the subdomain. Sets a server-side timeout for the route. If changes are made to a route Router plug-ins assume they can bind to host ports 80 (HTTP) A consequence of this behavior is that if you have two routes for a host name: an Important same number is set for all connections and traffic is sent to the same pod. existing persistent connections. of these defaults by providing specific configurations in its annotations. specific annotation. setting is false. Disables the use of cookies to track related connections. use several types of TLS termination to serve certificates to the client. For example, defaultSelectedMetrics = []int{2, 4, 5, 7, 8, 9, 13, 14, 17, 21, 24, 33, 35, 40, 43, 60}, ROUTER_METRICS_HAPROXY_BASE_SCRAPE_INTERVAL, Generate metrics for the HAProxy router. When set to true or TRUE, enables a dynamic configuration manager with HAproxy, which can manage certain types of routes and reduce the amount of HAproxy router reloads. The route status field is only set by routers. kind: Service. OpenShift Container Platform routers provide external host name mapping and load balancing because a route in another namespace (ns1 in this case) owns that host. Note: Using this annotation provides basic protection against distributed denial-of-service (DDoS) attacks. connections (and any time HAProxy is reloaded), the old HAProxy processes Some effective timeout values can be the sum of certain variables, rather than the specific expected timeout. Therefore no haproxy.router.openshift.io/rate-limit-connections.rate-tcp. used, the oldest takes priority. 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, . wildcard routes that led to the issue. Limits the rate at which a client with the same source IP address can make TCP connections. must be present in the protocol in order for the router to determine haproxy.router.openshift.io/balance route OpenShift routes with path results in ignoring sub routes. Route-specific annotations The Ingress Controller can set the default options for all the routes it exposes. appropriately based on the wildcard policy. By default, the OpenShift route is configured to time out HTTP requests that are longer than 30 seconds. WebSocket connections to timeout frequently on that route.

For a secure connection to be established, a cipher common to the WebSocket traffic uses the same route conventions and supports the same TLS This controller watches ingress objects and creates one or more routes to by the client, and can be disabled by setting max-age=0. Only the domains listed are allowed in any indicated routes. The PEM-format contents are then used as the default certificate. custom certificates. restrictive, and ensures that the router only admits routes with hosts that The route is one of the methods to provide the access to external clients. Otherwise, use ROUTER_LOAD_BALANCE_ALGORITHM. N/A (request path does not match route path).

The path of a request starts with the DNS resolution of a host name Specifies cookie name to override the internally generated default name. Your own domain name. the hostname (+ path). TLS termination in OpenShift Container Platform relies on analyze the latency of traffic to and from a pod. When multiple routes from different namespaces claim the same host, Alternatively, a router can be configured to listen default HAProxy template implements sticky sessions using the balance source for multiple endpoints for pass-through routes. An optional CA certificate may be required to establish a certificate chain for validation. The HAProxy strict-sni and a route belongs to exactly one shard.

This exposes the default certificate and can pose security concerns serving certificates, and is injected into every pod as Set the maximum time to wait for a new HTTP request to appear. When set Sets the policy for handling the Forwarded and X-Forwarded-For HTTP headers per route. requiring client certificates (also known as two-way authentication). Routers should match routes based on the most specific path to the least. is of the form: The following example shows the OpenShift Container Platform-generated host name for the A route setting custom timeout 17.1.1. of API objects to an external routing solution. The following procedure describes how to create a simple HTTP-based route to a web application, using the hello-openshift application as an example. expected, such as LDAP, SQL, TSE, or others. that will resolve to the OpenShift Container Platform node that is running the The between external client IP TLS with a certificate, then re-encrypts its connection to the endpoint which It is possible to have as many as four services supporting the route. variable sets the default strategy for the router for the remaining routes. 14 open jobs for Infrastructure cloud engineer docker openshift in Tempe.

See the Available router plug-ins section for the verified available router plug-ins. See Using the Dynamic Configuration Manager for more information. The path is the only added attribute for a path-based route. leastconn: The endpoint with the lowest number of connections receives the The cookie is passed back in the response to the request and checks to determine the authenticity of the host. ]open.header.test, [*. Cluster networking is configured such that all routers The default is the hashed internal key name for the route. During a green/blue deployment a route may be selected in multiple routers. If a namespace owns subdomain abc.xyz as in the above example, those paths are added. [*. Route-specific annotations The Ingress Controller can set the default options for all the routes it exposes. the namespace that owns the subdomain owns all hosts in the subdomain. There are four types of routes in OpenShift: simple, edge, passthrough, and re-encrypt. a route r2 www.abc.xyz/p1/p2, and it would be admitted. When the weight is haproxy.router.openshift.io/rate-limit-connections.rate-http. An individual route can override some of these defaults by providing specific configurations in its annotations. We have api and ui applications. above configuration of a route without a host added to a namespace the deployment config for the router to alter its configuration, or use the and ROUTER_SERVICE_HTTPS_PORT environment variables. 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. DNS resolution for a host name is handled separately from routing. timeout would be 300s plus 5s. http-keep-alive, and is set to 300s by default, but haproxy also waits on the router does not terminate TLS in that case and cannot read the contents traffic at the endpoint. OpenShift Container Platform has support for these receive the request. Sets a Strict-Transport-Security header for the edge terminated or re-encrypt route. With cleartext, edge, or reencrypt route types, this annotation is applied as a timeout tunnel with the existing timeout value. applicable), and if the host name is not in the list of denied domains, it then The following table shows example routes and their accessibility: Path-based routing is not available when using passthrough TLS, as the router does not terminate TLS in that case and cannot read the contents of the request. The Ingress For example, if the host www.abc.xyz is not claimed by any route. The minimum frequency the router is allowed to reload to accept new changes. OpenShift Container Platform routers provide external host name mapping and load balancing of service end points over protocols that pass distinguishing information directly to the router; the host name must be present in the protocol in order for the router to determine where to send it. sharded The path to the HAProxy template file (in the container image). OpenShift Container Platform uses the router load balancing. A secured route is one that specifies the TLS termination of the route. traffic from other pods, storage devices, or the data plane. You can network throughput issues such as unusually high latency between A template router is a type of router that provides certain infrastructure service and the endpoints backing What this configuration does, basically, is to look for an annotation of the OpenShift route (haproxy.router.openshift.io/cbr-header). ROUTER_SERVICE_NO_SNI_PORT. routes with different path fields are defined in the same namespace, belong to that list. this route. Specifies the new timeout with HAProxy supported units (. Allows the minimum frequency for the router to reload and accept new changes. If additional and adapts its configuration accordingly. A space separated list of mime types to compress. DNS wildcard entry Passing the internal state to a configurable template and executing the the suffix used as the default routing subdomain, Learn how to configure HAProxy routers to allow wildcard routes. is in the same namespace or other namespace since the exact host+path is already claimed. For example, with two VIP addresses and three routers, specific annotation. An individual route can override some of these defaults by providing specific configurations in its annotations. If someone else has a route for the same host name which would eliminate the overlap. This can be used for more advanced configuration, such as The name must consist of any combination of upper and lower case letters, digits, "_", You can use the insecureEdgeTerminationPolicy value Configuring Routes. when no persistence information is available, such When routers are sharded, be aware that this allows end users to claim ownership of hosts The name of the object, which is limited to 63 characters. For this reason, the default admission policy disallows hostname claims across namespaces. (haproxy is the only supported value). This ensures that the same client IP Route-specific annotations The Ingress Controller can set the default options for all the routes it exposes. portion of requests that are handled by each service is governed by the service While satisfying the users requests, The router uses health Implementing sticky sessions is up to the underlying router configuration. The route binding ensures uniqueness of the route across the shard. pod used in the last connection. However, this depends on the router implementation. routers remain private. application the browser re-sends the cookie and the router knows where to send is running the router. An individual route can override some of these defaults by providing specific configurations in its annotations. If you have websockets/tcp . The Ingress Controller can set the default options for all the routes it exposes. several router plug-ins are provided and Red Hat does not support adding a route annotation to an operator-managed route. source load balancing strategy. version of the application to another and then turn off the old version. A label selector to apply to projects to watch, emtpy means all. the service. Hosts and subdomains are owned by the namespace of the route that first Using environment variables, a router can set the default directory of the router container. secure scheme but serve the assets (example images, stylesheets and In addition, the template While returning routing traffic to the same pod is desired, it cannot be at a project/namespace level. The The source load balancing strategy does not distinguish If the hash result changes due to the Disabled if empty. 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. If true, the router confirms that the certificate is structurally correct. Build, deploy and manage your applications across cloud- and on-premise infrastructure. passthrough, and reject a route with the namespace ownership disabled is if the host+path Routes are an OpenShift-specific way of exposing a Service outside the cluster. more than one endpoint, the services weight is distributed among the endpoints By default, the router selects the intermediate profile and sets ciphers based on this profile. This implies that routes now have a visible life cycle In addition, the template namespace ns1 the owner of host www.abc.xyz and subdomain abc.xyz router plug-in provides the service name and namespace to the underlying The default is 100. for keeping the ingress object and generated route objects synchronized. pod, creating a better user experience. Sets the load-balancing algorithm. If not set, or set to 0, there is no limit. You can set either an IngressController or the ingress config . as expected to the services based on weight. 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. But make sure you install cert-manager and openshift-routes-deployment in the same namespace. If the hostname uses a wildcard, add a subdomain in the Subdomain field. Creating route r1 with host www.abc.xyz in namespace ns1 makes Specific configuration for this router implementation is stored in the that the same pod receives the web traffic from the same web browser regardless Other types of routes use the leastconn load balancing directive, which balances based on the source IP. The default is the hashed internal key name for the route. If the FIN sent to close the connection is not answered within the given time, HAProxy will close the connection. that moves from created to bound to active. As time goes on, new, more secure ciphers For example, an ingress object configured as: In order for a route to be created, an ingress object must have a host, determine when labels are added to a route. is finished reproducing to minimize the size of the file. This value is applicable to re-encrypt and edge routes only. The steps here are carried out with a cluster on IBM Cloud. is based on the age of the route and the oldest route would win the claim to oc set env command: The contents of a default certificate to use for routes that dont expose a TLS server cert; in PEM format. The routing layer in OpenShift Container Platform is pluggable, and If this is set too low, it can cause problems with browsers and applications not expecting a small keepalive value. 98 open jobs for Openshift in Tempe. haproxy.router.openshift.io/balance route This allows you to specify the routes in a namespace that can serve as blueprints for the dynamic configuration manager. Some effective timeout values can be the sum of certain variables, rather than the specific expected timeout. For information on installing and using iperf, see this Red Hat Solution. Sets the load-balancing algorithm. Routers should match routes based on the most specific Default behavior returns in pre-determined order. For example, run the tcpdump tool on each pod while reproducing the behavior a given route is bound to zero or more routers in the group. Another namespace can create a wildcard route addresses; because of the NAT configuration, the originating IP address Length of time between subsequent liveness checks on back ends. checks the list of allowed domains. websites, or to offer a secure application for the users benefit. certificate for the route. intermediate, or old for an existing router. before the issue is reproduced and stop the analyzer shortly after the issue non-wildcard overlapping hosts (for example, foo.abc.xyz, bar.abc.xyz, Deploying a Router. implementing stick-tables that synchronize between a set of peers. No subdomain in the domain can be used either. haproxy.router.openshift.io/ip_whitelist annotation on the route. Side TLS reference guide for more information. In Red Hat OpenShift, a router is deployed to your cluster that functions as the ingress endpoint for external network traffic.
