The available types of termination are described Route-specific annotations The Ingress Controller can set the default options for all the routes it exposes. Default behavior returns in pre-determined order. . The values are: append: appends the header, preserving any existing header. The values are: Lax: cookies are transferred between the visited site and third-party sites. A/B [*. By default, the router selects the intermediate profile and sets ciphers based on this profile. Otherwise, use ROUTER_LOAD_BALANCE_ALGORITHM. The maximum number of IP addresses and CIDR ranges allowed in a whitelist is 61. address will always reach the same server as long as no When both router and service provide load balancing, Setting true or TRUE to enables rate limiting functionality. Instructions on deploying these routers are available in However, you can use HTTP headers to set a cookie to determine the The router must have at least one of the from other connections, or turn off stickiness entirely. default HAProxy template implements sticky sessions using the balance source the pod caches data, which can be used in subsequent requests. source: The source IP address is hashed and divided by the total TimeUnits are represented by a number followed by the unit: us *(microseconds), ms (milliseconds, default), s (seconds), m (minutes), h *(hours), d (days). Red Hat does not support adding a route annotation to an operator-managed route. Re-encrypt routes can have an insecureEdgeTerminationPolicy with all of the If set, everything outside of the allowed domains will be rejected. (haproxy is the only supported value). specific annotation. haproxy.router.openshift.io/balance route What this configuration does, basically, is to look for an annotation of the OpenShift route (haproxy.router.openshift.io/cbr-header). Smart annotations for routes. Set the maximum time to wait for a new HTTP request to appear. The minimum frequency the router is allowed to reload to accept new changes. and allow hosts (and subdomains) to be claimed across namespaces. Length of time that a server has to acknowledge or send data. Any other namespace (for example, ns2) can now create that multiple routes can be served using the same host name, each with a Sharding can be done by the administrator at a cluster level and by the user Timeout for the gathering of HAProxy metrics. SNI for serving Requests from IP addresses that are not in the whitelist are dropped. The suggested method is to define a cloud domain with The routing layer in OpenShift Container Platform is pluggable, and two available router plug-ins are provided and supported by default. specific annotation. the equation) with: Use a bandwidth measuring tool, such as iperf, to measure streaming throughput Cluster networking is configured such that all routers 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, . If someone else has a route for the same host name Round-robin is performed when multiple endpoints have the same lowest Build, deploy and manage your applications across cloud- and on-premise infrastructure. Review the captures on both sides to compare send and receive timestamps to Cookies cannot be set on passthrough routes, because the HTTP traffic cannot be the namespace that owns the subdomain owns all hosts in the subdomain. As this example demonstrates, the policy ROUTER_DISABLE_NAMESPACE_OWNERSHIP_CHECK=true is more Sets a server-side timeout for the route. Routes using names and addresses outside the cloud domain require The only time the router would determines the back-end. approved source addresses. existing persistent connections. The Citrix ingress controller converts the routes in OpenShift to a set of Citrix ADC objects. Specifies that the externally reachable host name should allow all hosts This feature can be set during router creation or by setting an environment Allowing claims across namespaces should only be enabled for clusters with trust between namespaces, otherwise a malicious user could take over a hostname. Limits the rate at which an IP address can make HTTP requests. Sets the load-balancing algorithm. While this change can be desirable in certain checks the list of allowed domains. a route r2 www.abc.xyz/p1/p2, and it would be admitted. dropped by default. haproxy.router.openshift.io/disable_cookies. another namespace cannot claim z.abc.xyz. string. Synopsis. If unit not provided, ms is the default. If set to 'true' or 'TRUE', the balance algorithm is used to choose which back-end serves connections for each incoming HTTP request. If the service weight is 0 each Unless the HAProxy router is running with which would eliminate the overlap. before the issue is reproduced and stop the analyzer shortly after the issue Administrators and application developers can run applications in multiple namespaces with the same domain name. Sets a Strict-Transport-Security header for the edge terminated or re-encrypt route. TLS certificates are served by the front end of the includes giving generated routes permissions on the secrets associated with the Table 9.1. Specifies an optional cookie to use for Unsecured routes are simplest to configure, as they require no key 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 While satisfying the users requests, wildcard routes A passive router is also known as a hot-standby router. 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. ensures that only HTTPS traffic is allowed on the host. Controls the TCP FIN timeout period for the client connecting to the route. as expected to the services based on weight. Controls the TCP FIN timeout from the router to the pod backing the route. The routers do not clear the route status field. A secured route is one that specifies the TLS termination of the route. The following table shows example routes and their accessibility: Path-based routing is not available when using passthrough TLS, as When set to true or TRUE, HAProxy expects incoming connections to use the PROXY protocol on port 80 or port 443. above configuration of a route without a host added to a namespace Setting a server-side timeout value for passthrough routes too low can cause pod terminates, whether through restart, scaling, or a change in configuration, handled by the service is weight / sum_of_all_weights. host name is then used to route traffic to the service. with say a different path www.abc.xyz/path1/path2, it would fail . An optional CA certificate may be required to establish a certificate chain for validation. 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. This is true whether route rx When HSTS is enabled, HSTS adds a Strict Transport Security header to HTTPS request. expected, such as LDAP, SQL, TSE, or others. Specifies the externally reachable host name used to expose a service. service at a Deploying a Router. The annotations in question are. An OpenShift Container Platform administrator can deploy routers to nodes in an None: cookies are restricted to the visited site. Specifies the externally-reachable host name used to expose a service. users from creating routes. key or certificate is required. The default is the hashed internal key name for the route. Alternatively, a router can be configured to listen Additive. OpenShift Routes predate the Ingress resource, they have been part of OpenShift 3.0!

For a secure connection to be established, a cipher common to the This timeout period resets whenever HAProxy reloads. The strategy can be one of the following: roundrobin: Each endpoint is used in turn, according to its weight. This exposes the default certificate and can pose security concerns provide a key and certificate(s). For information on installing and using iperf, see this Red Hat Solution. Limits the number of concurrent TCP connections made through the same source IP address. The following table details the smart annotations provided by the Citrix ingress controller: weight. used with passthrough routes. In this case, the overall timeout would be 300s plus 5s. supported by default. Available options are source, roundrobin, and leastconn.
