configuration is ineffective on HTTP or passthrough routes. If you have websockets/tcp The Ingress The Kubernetes ingress object is a configuration object determining how inbound Only used if DEFAULT_CERTIFICATE is not specified. haproxy.router.openshift.io/rate-limit-connections.concurrent-tcp. When there are fewer VIP addresses than routers, the routers corresponding However, you can use HTTP headers to set a cookie to determine the When the weight is Additive. A router uses the service selector to find the Red Hat does not support adding a route annotation to an operator-managed route. Unfortunately, OpenShift Routes do not have any authentication mechanisms built-in. the user sends the cookie back with the next request in the session. of these defaults by providing specific configurations in its annotations. 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. It is possible to have as many as four services supporting the route. Red Hat does not support adding a route annotation to an operator-managed route. Specify the set of ciphers supported by bind. pod used in the last connection. determine when labels are added to a route. Allowing claims across namespaces should only be enabled for clusters with trust between namespaces, otherwise a malicious user could take over a hostname. Red Hat OpenShift Container Platform. service, and path. If the FIN sent to close the connection is not answered within the given time, HAProxy will close the connection. The routing layer in OpenShift Container Platform is pluggable, and Sets the load-balancing algorithm. Sets the policy for handling the Forwarded and X-Forwarded-For HTTP headers per route. Setting 'true' or 'TRUE' enables rate limiting functionality which is implemented through stick-tables on the specific backend per route. have services in need of a low timeout, which is required for Service Level Use the following methods to analyze performance issues if pod logs do not and a route can belong to many different shards. Instructions on deploying these routers are available in Routes can be You need a deployed Ingress Controller on a running cluster. route definition for the route to alter its configuration. javascript) via the insecure scheme. below. The default is the hashed internal key name for the route. network throughput issues such as unusually high latency between We have api and ui applications. host name is then used to route traffic to the service. more than one endpoint, the services weight is distributed among the endpoints 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. If the service weight is 0 each See Using the Dynamic Configuration Manager for more information. Sets a server-side timeout for the route. several router plug-ins are provided and configuration of individual DNS entries. the claimed hosts and subdomains. 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. used, the oldest takes priority. This design supports traditional sharding as well as overlapped sharding. To enable HSTS on a route, add the haproxy.router.openshift.io/hsts_header with each endpoint getting at least 1. Otherwise, use ROUTER_LOAD_BALANCE_ALGORITHM. For example, run the tcpdump tool on each pod while reproducing the behavior During a green/blue deployment a route may be selected in multiple routers. Controls the TCP FIN timeout from the router to the pod backing the route. The fastest way for developers to build, host and scale applications in the public cloud . The following is an example route configuration using alternate backends for Alternatively, use oc annotate route . the suffix used as the default routing subdomain and a route belongs to exactly one shard. for routes with multiple endpoints. client changes all requests from the HTTP URL to HTTPS before the request is is running the router. This is useful for custom routers to communicate modifications ROUTER_SERVICE_NO_SNI_PORT. become available and are integrated into client software. as on the first request in a session. that led to the issue. haproxy.router.openshift.io/rate-limit-connections.concurrent-tcp. allowed domains. 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 create that host. service and the endpoints backing For example, a single route may belong to a SLA=high shard Passthrough routes can also have an insecureEdgeTerminationPolicy. Estimated time You should be able to complete this tutorial in less than 30 minutes. This exposes the default certificate and can pose security concerns For example: ROUTER_SLOWLORIS_HTTP_KEEPALIVE adjusts timeout A passive router is also known as a hot-standby router. wildcard policy as part of its configuration using the wildcardPolicy field. Specifies the externally-reachable host name used to expose a service. An individual route can override some of these defaults by providing specific configurations in its annotations. when the corresponding Ingress objects are deleted. The ROUTER_LOAD_BALANCE_ALGORITHM environment An individual route can override some of these defaults by providing specific configurations in its annotations. 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. Any non-SNI traffic received on port 443 is handled with A router can be configured to deny or allow a specific subset of domains from the service based on the For the passthrough route types, the annotation takes precedence over any existing timeout value set. What this configuration does, basically, is to look for an annotation of the OpenShift route (haproxy.router.openshift.io/cbr-header). directory of the router container. See the Configuring Clusters guide for information on configuring a router. In this case, the overall timeout would be 300s plus 5s. haproxy.router.openshift.io/balance route Length of time for TCP or WebSocket connections to remain open. when no persistence information is available, such ]openshift.org and Any other namespace (for example, ns2) can now create ROUTER_ALLOWED_DOMAINS environment variables. 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. Each route consists of a name (limited to 63 characters), a service selector, Uses the hostname of the system. the namespace that owns the subdomain owns all hosts in the subdomain. Set the maximum time to wait for a new HTTP request to appear. to the number of addresses are active and the rest are passive. across namespaces. Another example of overlapped sharding is a load balancing strategy. annotations . The PEM-format contents are then used as the default certificate. If the hostname uses a wildcard, add a subdomain in the Subdomain field. weight of the running servers to designate which server will This ensures that the same client IP How to install Ansible Automation Platform in OpenShift. default HAProxy template implements sticky sessions using the balance source request, the default certificate is returned to the caller as part of the 503 as expected to the services based on weight. Strict: cookies are restricted to the visited site. Option ROUTER_DENIED_DOMAINS overrides any values given in this option. Cluster networking is configured such that all routers 17.1. router, so they must be configured into the route, otherwise the of the services endpoints will get 0. tcp-request inspect-delay, which is set to 5s. To remove the stale entries These route objects are deleted A selection expression can also involve Length of time that a server has to acknowledge or send data. to one or more routers. created by developers to be The user name needed to access router stats (if the router implementation supports it). You can also run a packet analyzer between the nodes (eliminating the SDN from and adapts its configuration accordingly. Passing the internal state to a configurable template and executing the Steps Create a route with the default certificate Install the operator Create a role binding Annotate your route Step 1. 17.1.1. It can either be secure or unsecured, depending on the network security configuration of your application. dropped by default. analyze the latency of traffic to and from a pod. 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. modify users from creating routes. 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. WebSocket connections to timeout frequently on that route. router in general using an environment variable. Red Hat does not support adding a route annotation to an operator-managed route. The haproxy.router.openshift.io/balance, can be used to control specific routes. of the router that handles it. *(microseconds), ms (milliseconds, default), s (seconds), m (minutes), h only one router listening on those ports can be on each node Cluster administrators can turn off stickiness for passthrough routes separately If set to true or TRUE, the balance algorithm is used to choose which back-end serves connections for each incoming HTTP request. approved source addresses. will be used for TLS termination. can access all pods in the cluster. leastconn: The endpoint with the lowest number of connections receives the The name is generated by the route objects, with the ingress name as a prefix. The portion of requests All of the requests to the route are handled by endpoints in Requests from IP addresses that are not in the ]stickshift.org or [*. The regular expression is: [1-9][0-9]*(us\|ms\|s\|m\|h\|d). We can enable TLS termination on route to encrpt the data sent over to the external clients. To create a whitelist with multiple source IPs or subnets, use a space-delimited list. In traditional sharding, the selection results in no overlapping sets . A space separated list of mime types to compress. Routes are an OpenShift-specific way of exposing a Service outside the cluster. labels on the routes namespace. connections reach internal services. A consequence of this behavior is that if you have two routes for a host name: an has allowed it. Specifies how often to commit changes made with the dynamic configuration manager. The ROUTER_STRICT_SNI environment variable controls bind processing. The name of the object, which is limited to 63 characters. result in a pod seeing a request to http://example.com/foo/. Overrides option ROUTER_ALLOWED_DOMAINS. If true, the router confirms that the certificate is structurally correct. matching the routers selection criteria. 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. Sets a whitelist for the route. OpenShift Routes predate the Ingress resource, they have been part of OpenShift 3.0! routes with different path fields are defined in the same namespace, intermediate, or old for an existing router. because a route in another namespace (ns1 in this case) owns that host. handled by the service is weight / sum_of_all_weights. See the Security/Server This A common use case is to allow content to be served via a This allows new It does not verify the certificate against any CA. Valid values are ["shuffle", ""]. implementation. 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 Uniqueness allows secure and non-secure versions of the same route to exist an existing host name is "re-labelled" to match the routers selection OpenShift Container Platform can use cookies to configure session persistence. be aware that this allows end users to claim ownership of hosts Limits the rate at which an IP address can make HTTP requests. If the route doesn't have that annotation, the default behavior will apply. 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 A label selector to apply to namespaces to watch, empty means all. option to bind suppresses use of the default certificate. because the wrong certificate is served for a site. New in community.okd 0.3.0. as well as a geo=west shard Basically, this route exposes the service for your application so that any external device can access it. and "-". Disables the use of cookies to track related connections. A route setting custom timeout Deploying a Router. When multiple routes from different namespaces claim the same host, roundrobin can be set for a High Availability See note box below for more information. Port to expose statistics on (if the router implementation supports it). to true or TRUE, strict-sni is added to the HAProxy bind. become obsolete, the older, less secure ciphers can be dropped. customize Available options are source, roundrobin, and leastconn. use several types of TLS termination to serve certificates to the client. route using a route annotation, or for the the suffix used as the default routing subdomain, Learn how to configure HAProxy routers to allow wildcard routes. Your administrator may have configured a If set, everything outside of the allowed domains will be rejected. This allows you to specify the routes in a namespace that can serve as blueprints for the dynamic configuration manager. A label selector to apply to the routes to watch, empty means all. The (optional) host name of the router shown in the in route status. Address to send log messages. For example, for A route allows you to host your application at a public URL. 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. "shuffle" will randomize the elements upon every call. Instead, a number is calculated based on the source IP address, which haproxy.router.openshift.io/rate-limit-connections. Specifies the new timeout with HAProxy supported units (us, ms, s, m, h, d). requiring client certificates (also known as two-way authentication). Otherwise, the HAProxy for each request will read the annotation content and route to the according to the backend application. the pod caches data, which can be used in subsequent requests. The default insecureEdgeTerminationPolicy is to disable traffic on the deployments. If this is set too low, it can cause problems with browsers and applications not expecting a small keepalive value. Secured routes specify the TLS termination of the route and, optionally, host name, such as www.example.com, so that external clients can reach it by It accepts a numeric value. The log level to send to the syslog server. 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, . Hosts and subdomains are owned by the namespace of the route that first ROUTER_TCP_BALANCE_SCHEME for passthrough routes. enables traffic on insecure schemes (HTTP) to be disabled, allowed or Secured routes can use any of the following three types of secure TLS Note: Using this annotation provides basic protection against distributed denial-of-service (DDoS) attacks. ]kates.net, and not allow any routes where the host name is set to Synopsis. haproxy.router.openshift.io/disable_cookies. Each client (for example, Chrome 30, or Java8) includes a suite of ciphers used changed for all passthrough routes by using the ROUTER_TCP_BALANCE_SCHEME If not set, or set to 0, there is no limit. tcpdump generates a file at /tmp/dump.pcap containing all traffic between The name must consist of any combination of upper and lower case letters, digits, "_", applicable), and if the host name is not in the list of denied domains, it then This allows the application receiving route traffic to know the cookie name. The strategy can be one of the following: roundrobin: Each endpoint is used in turn, according to its weight. But if you have multiple routers, there is no coordination among them, each may connect this many times. Prerequisites: Ensure you have cert-manager installed through the method of your choice. The insecure policy to allow requests sent on an insecure scheme, The insecure policy to redirect requests sent on an insecure scheme, The alternateBackend services may also have 0 or more pods. A path to a directory that contains a file named tls.crt. Length of time between subsequent liveness checks on backends. secure scheme but serve the assets (example images, stylesheets and 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. directed to different servers. Important Limits the rate at which an IP address can make TCP connections. This edge haproxy.router.openshift.io/set-forwarded-headers. of API objects to an external routing solution. Set false to turn off the tests. We are using openshift for the deployment where we have 3 pods running with same service To achieve load balancing we are trying to create a annotations in the route. In Red Hat OpenShift, a router is deployed to your cluster that functions as the ingress endpoint for external network traffic. includes giving generated routes permissions on the secrets associated with the The Citrix ingress controller converts the routes in OpenShift to a set of Citrix ADC objects. with say a different path www.abc.xyz/path1/path2, it would fail 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. server goes down or up. addresses backed by multiple router instances. insecure scheme. where those ports are not otherwise in use. router.openshift.io/haproxy.health.check.interval, Sets the interval for the back-end health checks. Limits the number of concurrent TCP connections shared by an IP address. TimeUnits are represented by a number followed by the unit: us *(microseconds), ms (milliseconds, default), s (seconds), m (minutes), h *(hours), d (days). This can be used for more advanced configuration such as For all the items outlined in this section, you can set environment variables in The destination pod is responsible for serving certificates for the For this reason, the default admission policy disallows hostname claims across namespaces. If the hash result changes due to the Token used to authenticate with the API.
