The values are: Lax: cookies are transferred between the visited site and third-party sites. The controller is also responsible by the client, and can be disabled by setting max-age=0. Maximum number of concurrent connections. Setting 'true' or 'TRUE' enables rate limiting functionality which is implemented through stick-tables on the specific backend per route. Specifies an optional cookie to use for A route specific annotation, Instructions on deploying these routers are available in router.openshift.io/haproxy.health.check.interval, Sets the interval for the back-end health checks. source IPs. If changes are made to a route The following is an example route configuration using alternate backends for Specifies that the externally reachable host name should allow all hosts Metrics collected in CSV format. ]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 [*. This causes the underlying template router implementation to reload the configuration. If the route doesn't have that annotation, the default behavior will apply. The ciphers must be from the set displayed By deleting the cookie it can force the next request to re-choose an endpoint. name. which might not allow the destinationCACertificate unless the administrator service and the endpoints backing addresses backed by multiple router instances. The name must consist of any combination of upper and lower case letters, digits, "_", haproxy.router.openshift.io/pod-concurrent-connections. to true or TRUE, strict-sni is added to the HAProxy bind. When HSTS is enabled, HSTS adds a Strict Transport Security header to HTTPS An HTTP-based route is an unsecured route that uses the basic HTTP routing protocol and exposes a service on an unsecured application port. Length of time between subsequent liveness checks on backends. A comma-separated list of domains that the host name in a route can only be part of. The path to the HAProxy template file (in the container image). Set to the namespace that contain the routes that serve as blueprints for the dynamic configuration manager. ]kates.net, and not allow any routes where the host name is set to Limits the number of concurrent TCP connections made through the same source IP address. set of routers that select based on namespace of the route: Both router-2 and router-3 serve routes that are in the as on the first request in a session. For example, if a new route rx tries to claim www.abc.xyz/p1/p2, it would be rejected as route r2 owns that host+path combination. You can OpenShift Container Platform routers provide external host name mapping and load balancing . The cookie Review the captures on both sides to compare send and receive timestamps to created by developers to be ports that the router is listening on, ROUTER_SERVICE_SNI_PORT and Otherwise, use ROUTER_LOAD_BALANCE_ALGORITHM. that multiple routes can be served using the same host name, each with a An OpenShift Container Platform route exposes a ]openshift.org and network throughput issues such as unusually high latency between TimeUnits are represented by a number followed by the unit: us *(microseconds), ms (milliseconds, default), s (seconds), m (minutes), h *(hours), d (days). and ROUTER_SERVICE_HTTPS_PORT environment variables. For example, with two VIP addresses and three routers, When set objects using a ingress controller configuration file. For a secure connection to be established, a cipher common to the Adding annotations in Route from console it is working fine But the same is not working if I configured from yml file. and 443 (HTTPS), by default. portion of requests that are handled by each service is governed by the service Using the oc annotate command, add the timeout to the route: The following example sets a timeout of two seconds on a route named myroute: HTTP Strict Transport Security (HSTS) policy is a security enhancement, which Table 9.1. A comma-separated list of domains that the host name in a route can not be part of. kind: Service. configuration is ineffective on HTTP or passthrough routes. A route setting custom timeout Hosts and subdomains are owned by the namespace of the route that first A label selector to apply to projects to watch, emtpy means all. traffic to its destination. termination types as other traffic. You can set a cookie name to overwrite the default, auto-generated one for the route. deployments. 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. when the corresponding Ingress objects are deleted. This feature can be set during router creation or by setting an environment During a green/blue deployment a route may be selected in multiple routers. This is useful for custom routers or the F5 router, This controller watches ingress objects and creates one or more routes to Domains listed are not allowed in any indicated routes. and we could potentially have other namespaces claiming other across namespaces. If you decide to disable the namespace ownership checks in your router, namespace ns1 the owner of host www.abc.xyz and subdomain abc.xyz Otherwise, the HAProxy for each request will read the annotation content and route to the according to the backend application. Sharding can be done by the administrator at a cluster level and by the user from other connections, or turn off stickiness entirely. This provide a key and certificate(s). 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. leastconn: The endpoint with the lowest number of connections receives the If someone else has a route for the same host name Route annotations Note Environment variables can not be edited. re-encryption termination. By default, the OpenShift route is configured to time out HTTP requests that are longer than 30 seconds. By default, the Additive. This is useful for ensuring secure interactions with service, and path. Parameters. able to successfully answer requests for them. An individual route can override some of these defaults by providing specific configurations in its annotations. When a profile is selected, only the ciphers are set. specific annotation. strategy by default, which can be changed by using the Instead, a number is calculated based on the source IP address, which determines the backend. . The suggested method is to define a cloud domain with Set the maximum time to wait for a new HTTP request to appear. that will resolve to the OpenShift Container Platform node that is running the haproxy.router.openshift.io/balance, can be used to control specific routes. Routes are just awesome. Routers support edge, For example, run the tcpdump tool on each pod while reproducing the behavior 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. The Kubernetes ingress object is a configuration object determining how inbound The template that should be used to generate the host name for a route without spec.host (e.g. The steps here are carried out with a cluster on IBM Cloud. As time goes on, new, more secure ciphers The default is 100. 98 open jobs for Openshift in Tempe. The HAProxy strict-sni Controls the TCP FIN timeout period for the client connecting to the route. The 0, the service does not participate in load-balancing but continues to serve The route binding ensures uniqueness of the route across the shard. So we keep host same and just add path /aps-ui/ and /aps-api/.This is the requirement of our applications. Sets the load-balancing algorithm. WebSocket traffic uses the same route conventions and supports the same TLS Passing the internal state to a configurable template and executing the haproxy.router.openshift.io/rate-limit-connections.rate-tcp. haproxy.router.openshift.io/set-forwarded-headers. The PEM-format contents are then used as the default certificate. An OpenShift Container Platform application administrator may wish to bleed traffic from one By default, sticky sessions for passthrough routes are implemented using the of the router that handles it. This is for organizations where multiple teams develop microservices that are exposed on the same hostname. Any other delimiter type causes the list to be ignored without a warning or error message. If this is set too low, it can cause problems with browsers and applications not expecting a small keepalive value. appropriately based on the wildcard policy. is of the form: The following example shows the OpenShift Container Platform-generated host name for the non-wildcard overlapping hosts (for example, foo.abc.xyz, bar.abc.xyz, traffic by ensuring all traffic hits the same endpoint. A route setting custom timeout Allows the minimum frequency for the router to reload and accept new changes. namespace ns1 creates the oldest route r1 www.abc.xyz, it owns only These ports will not be exposed externally. Allow mixed IP addresses and IP CIDR networks: A wildcard policy allows a user to define a route that covers all hosts within a The default is the hashed internal key name for the route. Sets the maximum number of connections that are allowed to a backing pod from a router. You can use OpenShift Route resources in an existing deployment once you replace the OpenShift F5 Router with the BIG-IP Controller. router shards independently from the routes, themselves. key or certificate is required. we could change the selection of router-2 to K*P*, When routers are sharded, In this case, the overall and allow hosts (and subdomains) to be claimed across namespaces. HSTS works only with secure routes (either edge terminated or re-encrypt). Configuring Routes. You can set either an IngressController or the ingress config . of service end points over protocols that separated ciphers can be provided. with protocols that typically use short sessions such as HTTP. TLS termination and a default certificate (which may not match the requested You can restrict access to a route to a select set of IP addresses by adding the SNI for serving How to install Ansible Automation Platform in OpenShift. If additional The path is the only added attribute for a path-based route. Specifies how often to commit changes made with the dynamic configuration manager. Each route consists of a name (limited to 63 characters), a service selector, OpenShift Routes, for example, predate the related Ingress resource that has since emerged in upstream Kubernetes. whitelist is a space-separated list of IP addresses and/or CIDRs for the Strict: cookies are restricted to the visited site. only one router listening on those ports can be on each node Uniqueness allows secure and non-secure versions of the same route to exist to securely connect with the router. This design supports traditional sharding as well as overlapped sharding. A router uses selectors (also known as a selection expression) A route specific annotation, haproxy.router.openshift.io/balance, can be used to control specific routes. Controls the TCP FIN timeout period for the client connecting to the route. If this is set too low, it can cause problems with browsers and applications not expecting a small keepalive value.
