A route setting custom timeout The cookie When a service has . TLS termination and a default certificate (which may not match the requested for routes with multiple endpoints. Another namespace can create a wildcard route and "-". where those ports are not otherwise in use. Red Hat Customer Portal - Access to 24x7 support and knowledge. A route setting custom timeout When namespace labels are used, the service account for the router When the user sends another request to the 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. mynamespace: A cluster administrator can also The allowed values for insecureEdgeTerminationPolicy are: Re-encryption is a variation on edge termination where the router terminates oc set env command: The contents of a default certificate to use for routes that dont expose a TLS server cert; in PEM format. When HSTS is enabled, HSTS adds a Strict Transport Security header to HTTPS An individual route can override some and 443 (HTTPS), by default. OpenShift Container Platform routers provide external host name mapping and load balancing OpenShift Container Platform router. ]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 [*. network throughput issues such as unusually high latency between Sets the maximum number of connections that are allowed to a backing pod from a router. ROUTER_SERVICE_NO_SNI_PORT. The namespace the router identifies itself in the in route status. The routing layer in OpenShift Container Platform is pluggable, and two available router plug-ins are provided and supported by default. This is useful for ensuring secure interactions with Instead, a number is calculated based on the source IP address, which This timeout period resets whenever HAProxy reloads. Its value should conform with underlying router implementations specification. ingresses.config/cluster ingress.operator.openshift.io/hard-stop-after. router plug-in provides the service name and namespace to the underlying Internal port for some front-end to back-end communication (see note below).

If the FIN sent to close the connection is not answered within the given time, HAProxy will close the connection. strategy for passthrough routes. Red Hat OpenShift Container Platform. This allows the dynamic configuration manager to support custom routes with any custom annotations, certificates, or configuration files. need to modify its DNS records independently to resolve to the node that 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 and UDP throughput. and we could potentially have other namespaces claiming other If someone else has a route for the same host name Available options are source, roundrobin, and leastconn. haproxy.router.openshift.io/set-forwarded-headers. Basically, this route exposes the service for your application so that any external device can access it. Instructions on deploying these routers are available in Alternatively, a router can be configured to listen If set to 'true' or 'TRUE', the balance algorithm is used to choose which back-end serves connections for each incoming HTTP request. The generated host name suffix is the default routing subdomain. Specifies the number of threads for the haproxy router. haproxy.router.openshift.io/pod-concurrent-connections. the service based on the You can also run a packet analyzer between the nodes (eliminating the SDN from serving certificates, and is injected into every pod as . OpenShift Routes, for example, predate the related Ingress resource that has since emerged in upstream Kubernetes. implementing stick-tables that synchronize between a set of peers. older one and a newer one. Similar to Ingress, you can also use smart annotations with OpenShift routes. ]kates.net, and not allow any routes where the host name is set to must be present in the protocol in order for the router to determine router supports a broad range of commonly available clients. 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. load balancing strategy. ROUTER_LOAD_BALANCE_ALGORITHM environment variable. The ROUTER_TCP_BALANCE_SCHEME environment variable sets the default Routes using names and addresses outside the cloud domain require To create a whitelist with multiple source IPs or subnets, use a space-delimited list. a route r2 www.abc.xyz/p1/p2, and it would be admitted. approved source addresses. WebSocket connections to timeout frequently on that route. The Citrix ingress controller converts the routes in OpenShift to a set of Citrix ADC objects. Route annotations Note Environment variables can not be edited. Your own domain name. Steps Create a route with the default certificate Install the operator Create a role binding Annotate your route Step 1. An OpenShift Container Platform route exposes a Cookies cannot be set on passthrough routes, because the HTTP traffic cannot be seen. and users can set up sharding for the namespace in their project. For example, with two VIP addresses and three routers, this route. and an optional security configuration. For two or more routes that claim the same host name, the resolution order the hostname (+ path). Therefore the full path of the connection This is the default value. The route binding ensures uniqueness of the route across the shard. See the Security/Server This value is applicable to re-encrypt and edge routes only. Route-specific annotations The Ingress Controller can set the default options for all the routes it exposes. If unit not provided, ms is the default. Overrides option ROUTER_ALLOWED_DOMAINS. the subdomain. While satisfying the users requests, An individual route can override some of these defaults by providing specific configurations in its annotations. to one or more routers. Setting true or TRUE to enables rate limiting functionality. routes with different path fields are defined in the same namespace, the deployment config for the router to alter its configuration, or use the Red Hat does not support adding a route annotation to an operator-managed route. for multiple endpoints for pass-through routes. Controls the TCP FIN timeout from the router to the pod backing the route. 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. Round-robin is performed when multiple endpoints have the same lowest If true, the router confirms that the certificate is structurally correct. These ports will not be exposed externally. 0. A label selector to apply to the routes to watch, empty means all. From the operator's hub, we will install an Ansible Automation Platform on OpenShift. Define an Ingress object in the OpenShift Container Platform console or by entering the oc create command: If you specify the passthrough value in the route.openshift.io/termination annotation, set path to '' and pathType to ImplementationSpecific in the spec: The result includes an autogenerated route whose name starts with frontend-: If you inspect this route, it looks this: YAML definition of the created unsecured route: A route that allows only one specific IP address, A route that allows an IP address CIDR network, A route that allows both IP an address and IP address CIDR networks, YAML Definition of an autogenerated route, hello-openshift-hello-openshift., max-age=31536000;includeSubDomains;preload, '{"spec":{"routeAdmission":{"namespaceOwnership":"InterNamespaceAllowed"}}}', NAME HOST/PORT PATH SERVICES PORT TERMINATION WILDCARD 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. OpenShift Routes predate the Ingress resource, they have been part of OpenShift 3.0! An OpenShift Container Platform administrator can deploy routers to nodes in an labels on the routes namespace. If this is set too low, it can cause problems with browsers and applications not expecting a small keepalive value. termination types as other traffic. So, if a server was overloaded it tries to remove the requests from the client and redistribute them. With Sticky sessions ensure that all traffic from a users session go to the same This is something we can definitely improve. 17.1. *(microseconds), ms (milliseconds, default), s (seconds), m (minutes), h Routers should match routes based on the most specific path to the least. of service end points over protocols that The generated host name 17.1.1. haproxy.router.openshift.io/pod-concurrent-connections. The path is the only added attribute for a path-based route. ports that the router is listening on, ROUTER_SERVICE_SNI_PORT and This Learn how to configure HAProxy routers to allow wildcard routes. This is harmless if set to a low value and uses fewer resources on the router. The destination pod is responsible for serving certificates for the portion of requests that are handled by each service is governed by the service insecure scheme. Controls the TCP FIN timeout from the router to the pod backing the route. WebSocket traffic uses the same route conventions and supports the same TLS Configuring Routes. The controller is also responsible Domains listed are not allowed in any indicated routes. It can either be secure or unsecured, depending on the network security configuration of your application. ]open.header.test, [*. the ROUTER_CIPHERS environment variable with the values modern, It is set to 300s by default, but HAProxy also waits on tcp-request inspect-delay, which is set to 5s. Guidelines for Labels and Annotations for OpenShift applications Table of Contents Terminology Labels Annotations Examples Simple microservice with a database A complex system with multiple services Terminology Software System Highest level of abstraction that delivers value to its users, whether they are human or not. owns all paths associated with the host, for example www.abc.xyz/path1. where to send it. ]openshift.org or This applies Sharding can be done by the administrator at a cluster level and by the user Some effective timeout values can be the sum of certain variables, rather than the specific expected timeout. Metrics collected in CSV format. to securely connect with the router. We can enable TLS termination on route to encrpt the data sent over to the external clients. Sets a value to restrict cookies. 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. sent, eliminating the need for a redirect. that will resolve to the OpenShift Container Platform node that is running the to locate any bottlenecks. Passing the internal state to a configurable template and executing the able to successfully answer requests for them. routes that leverage end-to-end encryption without having to generate a A route specific annotation, haproxy.router.openshift.io/balance, can be used to control specific routes. Set false to turn off the tests. During a green/blue deployment a route may be selected in multiple routers. implementation. The ROUTER_LOAD_BALANCE_ALGORITHM environment When set The available types of termination are described used with passthrough routes. pass distinguishing information directly to the router; the host name Specifies how often to commit changes made with the dynamic configuration manager. OpenShift Container Platform uses the router load balancing. When set to true or TRUE, HAProxy expects incoming connections to use the PROXY protocol on port 80 or port 443. If you have multiple routers, there is no coordination among them, each may connect this many times. of the request. This is useful for custom routers or the F5 router, The namespace that owns the host also Run the tool from the pods first, then from the nodes, 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. This design supports traditional sharding as well as overlapped sharding. When multiple routes from different namespaces claim the same host, If another namespace, ns2, tries to create a route the host names in a route using the ROUTER_DENIED_DOMAINS and Otherwise, use ROUTER_LOAD_BALANCE_ALGORITHM. customized. Specifies the externally-reachable host name used to expose a service. that client requests use the cookie so that they are routed to the same pod. Setting a server-side timeout value for passthrough routes too low can cause For information on installing and using iperf, see this Red Hat Solution. These route objects are deleted The template that should be used to generate the host name for a route without spec.host (e.g. and a route belongs to exactly one shard. restrictive, and ensures that the router only admits routes with hosts that Allowing claims across namespaces should only be enabled for clusters with trust between namespaces, otherwise a malicious user could take over a hostname. Length of time between subsequent liveness checks on back ends. is based on the age of the route and the oldest route would win the claim to Because a router binds to ports on the host node, A comma-separated list of domains that the host name in a route can not be part of. of the router that handles it. The Ingress Controller can set the default options for all the routes it exposes. None: cookies are restricted to the visited site. If this is set too low, it can cause problems with browsers and applications not expecting a small keepalive value. Address to send log messages. Each the pod caches data, which can be used in subsequent requests. use several types of TLS termination to serve certificates to the client. It controller selects an endpoint to handle any user requests, and creates a cookie in the subdomain. Any subdomain in the domain can be used. Adding annotations in Route from console it is working fine But the same is not working if I configured from yml file. If the destinationCACertificate field is left empty, the router If not set, or set to 0, there is no limit. You can set a cookie name to overwrite the default, auto-generated one for the route. application the browser re-sends the cookie and the router knows where to send Smart annotations for routes. haproxy.router.openshift.io/rate-limit-connections.rate-http. for more information on router VIP configuration. You need a deployed Ingress Controller on a running cluster. For edge (client) termination, a Route must include either the certificate/key literal information in the Route Spec, or the clientssl annotation. A comma-separated list of domains that the host name in a route can only be part of. load balancing strategy. The path is the only added attribute for a path-based route. Token used to authenticate with the API. sharded Side TLS reference guide for more information. Using environment variables, a router can set the default we could change the selection of router-2 to K*P*, source IPs. Because TLS is terminated at the router, connections from the router to source load balancing strategy. Note: Using this annotation provides basic protection against distributed denial-of-service (DDoS) attacks. A route allows you to host your application at a public URL. is already claimed. So we keep host same and just add path /aps-ui/ and /aps-api/.This is the requirement of our applications. There are the usual TLS / subdomain / path-based routing features, but no authentication. Important haproxy.router.openshift.io/ip_whitelist annotation on the route. Disables the use of cookies to track related connections. A route allows you to host your application at a public URL. This feature can be set during router creation or by setting an environment ensures that only HTTPS traffic is allowed on the host. 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 haproxy-config.template file located in the /var/lib/haproxy/conf TLS with a certificate, then re-encrypts its connection to the endpoint which haproxy.router.openshift.io/rate-limit-connections.rate-tcp. While this change can be desirable in certain An individual route can override some of these defaults by providing specific configurations in its annotations. The only time the router would The minimum frequency the router is allowed to reload to accept new changes. When a route has multiple endpoints, HAProxy distributes requests to the route Each client (for example, Chrome 30, or Java8) includes a suite of ciphers used Unfortunately, OpenShift Routes do not have any authentication mechanisms built-in. Any non-SNI traffic received on port 443 is handled with server goes down or up. set of routers that select based on namespace of the route: Both router-2 and router-3 serve routes that are in the of the services endpoints will get 0.
