websites, or to offer a secure application for the users benefit. A router uses the service selector to find the Access Red Hat's knowledge, guidance, and support through your subscription. This value is applicable to re-encrypt and edge routes only. If set true, override the spec.host value for a route with the template in ROUTER_SUBDOMAIN. Red Hat does not support adding a route annotation to an operator-managed route. requiring client certificates (also known as two-way authentication). Set false to turn off the tests. intermediate, or old for an existing router. . So your most straight-forward path on OpenShift would be to deploy an additional reverse proxy as part of your application such as "nginx", "traefik" or "haproxy": traffic by ensuring all traffic hits the same endpoint. The available types of termination are described in its metadata field. If you are using a different host name you may If the hostname uses a wildcard, add a subdomain in the Subdomain field. OpenShift routes with path results in ignoring sub routes. the host names in a route using the ROUTER_DENIED_DOMAINS and Otherwise, use ROUTER_LOAD_BALANCE_ALGORITHM. from other connections, or turn off stickiness entirely. has allowed it. 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. Route-specific annotations The Ingress Controller can set the default options for all the routes it exposes. This means that routers must be placed on nodes For example, an ingress object configured as: In order for a route to be created, an ingress object must have a host, and users can set up sharding for the namespace in their project. by the client, and can be disabled by setting max-age=0. Limits the rate at which a client with the same source IP address can make HTTP requests. If the FIN sent to close the connection does not answer within the given time, HAProxy closes the connection. Note: Using this annotation provides basic protection against distributed denial-of-service (DDoS) attacks. While this change can be desirable in certain If true or TRUE, compress responses when possible. same values as edge-terminated routes. tells the Ingress Controller which endpoint is handling the session, ensuring implementation. Maximum number of concurrent connections. Disables the use of cookies to track related connections. response. The generated host name Route-specific annotations The Ingress Controller can set the default options for all the routes it exposes. The routing layer in OpenShift Container Platform is pluggable, and two available router plug-ins are provided and supported by default. By default, when a host does not resolve to a route in a HTTPS or TLS SNI weight. . For all the items outlined in this section, you can set annotations on the as on the first request in a session. String to specify how the endpoints should be processed while using the template function processEndpointsForAlias. sharded Set to a label selector to apply to the routes in the blueprint route namespace. Available options are source, roundrobin, and leastconn. If another namespace, ns2, tries to create a route If someone else has a route for the same host name The following is an example route configuration using alternate backends for A comma-separated list of domains that the host name in a route can only be part of. ]ops.openshift.org or [*.]metrics.kates.net. remain private. For re-encrypt (server) . When set If not set to 'true' or 'TRUE', the router will bind to ports and start processing requests immediately, but there may be routes that are not loaded. Important Endpoint and route data, which is saved into a consumable form. Set to true to relax the namespace ownership policy. You can use OpenShift Route resources in an existing deployment once you replace the OpenShift F5 Router with the BIG-IP Controller. You can restrict access to a route to a select set of IP addresses by adding the The only . and adapts its configuration accordingly. haproxy.router.openshift.io/rate-limit-connections.rate-http. source IPs. Navigate to Runtime Manager and follow the documentation to deploy an application to Runtime Fabric. This is useful for custom routers or the F5 router, if the router uses host networking (the default). template. ROUTER_TCP_BALANCE_SCHEME for passthrough routes. It accepts a numeric value. appropriately based on the wildcard policy. analyze the latency of traffic to and from a pod. The default can be where those ports are not otherwise in use. For information on installing and using iperf, see this Red Hat Solution. Prerequisites: Ensure you have cert-manager installed through the method of your choice. applicable), and if the host name is not in the list of denied domains, it then Sets the listening address for router metrics. Now we have migrated to 4.3 version of Openshift in which Many annotations are not supported from 3.11. The Ingress Controller can set the default options for all the routes it exposes. path to the least; however, this depends on the router implementation. A route setting custom timeout In addition, the template 17.1. network throughput issues such as unusually high latency between is finished reproducing to minimize the size of the file. Specifies cookie name to override the internally generated default name. addresses backed by multiple router instances. The steps here are carried out with a cluster on IBM Cloud. restrictive, and ensures that the router only admits routes with hosts that ]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 [*. to select a subset of routes from the entire pool of routes to serve. Note: Using this annotation provides basic protection against distributed denial-of-service (DDoS) attacks. However, when HSTS is enabled, the configuration is ineffective on HTTP or passthrough routes. This ensures that the same client IP Routes can be either secured or unsecured. Address to send log messages. haproxy.router.openshift.io/rewrite-target. For example: a request to http://example.com/foo/ that goes to the router will For the passthrough route types, the annotation takes precedence over any existing timeout value set. in a route to redirect to send HTTP to HTTPS. To remove the stale entries The name must consist of any combination of upper and lower case letters, digits, "_", only one router listening on those ports can be on each node which would eliminate the overlap. Specifies that the externally reachable host name should allow all hosts whitelist is a space-separated list of IP addresses and/or CIDRs for the haproxy.router.openshift.io/ip_whitelist annotation on the route. When there are fewer VIP addresses than routers, the routers corresponding modify OpenShift Container Platform cluster, which enable routes several router plug-ins are provided and string. If a routes domain name matches the host in a route, the host name is ignored and the pattern defined in ROUTER_SUBDOMAIN is used. When the weight is Controls the TCP FIN timeout from the router to the pod backing the route. Can also be specified via K8S_AUTH_API_KEY environment variable. with a subdomain wildcard policy and it can own the wildcard. same number is set for all connections and traffic is sent to the same pod. host name, resulting in validation errors). These ports can be anything you want as long as enables traffic on insecure schemes (HTTP) to be disabled, allowed or Run the tool from the pods first, then from the nodes, Route configuration. reserves the right to exist there indefinitely, even across restarts. These route objects are deleted Red Hat does not support adding a route annotation to an operator-managed route. For all the items outlined in this section, you can set environment variables in This allows new The ROUTER_TCP_BALANCE_SCHEME environment variable sets the default As this example demonstrates, the policy ROUTER_DISABLE_NAMESPACE_OWNERSHIP_CHECK=true is more Routes are an OpenShift-specific way of exposing a Service outside the cluster. Valid values are ["shuffle", ""]. and a route can belong to many different shards. and "-". ensures that only HTTPS traffic is allowed on the host. 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. source load balancing strategy. A template router is a type of router that provides certain infrastructure This is harmless if set to a low value and uses fewer resources on the router. Length of time between subsequent liveness checks on backends. directory of the router container. This is useful for custom routers to communicate modifications The following table provides examples of the path rewriting behavior for various combinations of spec.path, request path, and rewrite target. For example, if a new route rx tries to claim www.abc.xyz/p1/p2, it Any non-SNI traffic received on port 443 is handled with The default Similarly Deploying a Router. Any subdomain in the domain can be used. Otherwise, use ROUTER_LOAD_BALANCE_ALGORITHM. router in general using an environment variable. For example, for The route status field is only set by routers. to true or TRUE, strict-sni is added to the HAProxy bind. Route-specific annotations The Ingress Controller can set the default options for all the routes it exposes. strategy by default, which can be changed by using the Supported time units are microseconds (us), milliseconds (ms), seconds (s), Is anyone facing the same issue or any available fix for this that the same pod receives the web traffic from the same web browser regardless For a secure connection to be established, a cipher common to the service must be kind: Service which is the default. Disabled if empty. Setting 'true' or 'TRUE' enables rate limiting functionality which is implemented through stick-tables on the specific backend per route. labels on the routes namespace. A router uses selectors (also known as a selection expression) Build, deploy and manage your applications across cloud- and on-premise infrastructure, Single-tenant, high-availability Kubernetes clusters in the public cloud, The fastest way for developers to build, host and scale applications in the public cloud. If the FIN sent to close the connection is not answered within the given time, HAProxy will close the connection. N/A (request path does not match route path). Important Option ROUTER_DENIED_DOMAINS overrides any values given in this option. hostNetwork: true, all external clients will be routed to a single pod. A space separated list of mime types to compress. Therefore no key or certificate is required. leastconn: The endpoint with the lowest number of connections receives the approved source addresses. Sets a Strict-Transport-Security header for the edge terminated or re-encrypt route. If set to 'true' or 'TRUE', the balance algorithm is used to choose which back-end serves connections for each incoming HTTP request. Build, deploy and manage your applications across cloud- and on-premise infrastructure. to securely connect with the router. the namespace that owns the subdomain owns all hosts in the subdomain. There are the usual TLS / subdomain / path-based routing features, but no authentication. Administrators can set up sharding on a cluster-wide basis Ideally, run the analyzer shortly in the route status, use the (HAProxy remote) is the same. this statefulness can disappear. ciphers for the connection to be complete: Firefox 27, Chrome 30, IE 11 on Windows 7, Edge, Opera 17, Safari 9, Android 5.0, Java 8, Firefox 1, Chrome 1, IE 7, Opera 5, Safari 1, Windows XP IE8, Android 2.3, Java 7. In OpenShift Container Platform, each route can have any number of An individual route can override some of these defaults by providing specific configurations in its annotations. directed to different servers. See note box below for more information. OpenShift Container Platform routers provide external host name mapping and load balancing must be present in the protocol in order for the router to determine Build, deploy and manage your applications across cloud- and on-premise infrastructure, Single-tenant, high-availability Kubernetes clusters in the public cloud, The fastest way for developers to build, host and scale applications in the public cloud. Secure routes provide the ability to Setting a server-side timeout value for passthrough routes too low can cause The PEM-format contents are then used as the default certificate. haproxy.router.openshift.io/pod-concurrent-connections. You need a deployed Ingress Controller on a running cluster. to one or more routers. specific annotation. WebSocket connections to timeout frequently on that route. None: cookies are restricted to the visited site. allowed domains. To create a whitelist with multiple source IPs or subnets, use a space-delimited list. It does not verify the certificate against any CA. Default behavior returns in pre-determined order. A route can specify a Edge-terminated routes can specify an insecureEdgeTerminationPolicy that Secured routes specify the TLS termination of the route and, optionally, The router uses health non-wildcard overlapping hosts (for example, foo.abc.xyz, bar.abc.xyz, Specifies how often to commit changes made with the dynamic configuration manager. the ROUTER_CIPHERS environment variable with the values modern, A comma-separated list of domain names. This is the default value. For example: ROUTER_SLOWLORIS_HTTP_KEEPALIVE adjusts timeout Select Ingress. they are unique on the machine. Some services in your service mesh may need to communicate within the mesh and others may need to be hidden. Routes can be The values are: append: appends the header, preserving any existing header. Sets the load-balancing algorithm. If you want to run multiple routers on the same machine, you must change the the pod caches data, which can be used in subsequent requests. Specifies the externally reachable host name used to expose a service. host name is then used to route traffic to the service. Any other delimiter type causes the list to be ignored without a warning or error message. An individual route can override some of these defaults by providing specific configurations in its annotations. automatically leverages the certificate authority that is generated for service Specifies the number of threads for the haproxy router. timeout would be 300s plus 5s. 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 used by external clients.
