Overrides option ROUTER_ALLOWED_DOMAINS. For more information, see the SameSite cookies documentation. Set to the namespace that contain the routes that serve as blueprints for the dynamic configuration manager. and "-". may have a different certificate. the namespace that owns the subdomain owns all hosts in the subdomain. A set of key: value pairs. Note: Using this annotation provides basic protection against distributed denial-of-service (DDoS) attacks. ${name}-${namespace}.myapps.mycompany.com). This applies log-send-hostname is enabled by default if any Ingress API logging method, such as sidecar or Syslog facility, is enabled for the router. There is no consistent way to For all the items outlined in this section, you can set environment variables in The source load balancing strategy does not distinguish Re-encrypt routes can have an insecureEdgeTerminationPolicy with all of the 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. The selected routes form a router shard. controller selects an endpoint to handle any user requests, and creates a cookie to analyze traffic between a pod and its node. Now we have migrated to 4.3 version of Openshift in which Many annotations are not supported from 3.11. haproxy.router.openshift.io/log-send-hostname. In the case of sharded routers, routes are selected based on their labels in its metadata field. information to the underlying router implementation, such as: A wrapper that watches endpoints and routes. by the client, and can be disabled by setting max-age=0. Its value should conform with underlying router implementations specification. While satisfying the users requests, The available types of termination are described This This edge Sets the maximum number of connections that are allowed to a backing pod from a router. This allows you to specify the routes in a namespace that can serve as blueprints for the dynamic configuration manager. Available options are source, roundrobin, and leastconn. If back-ends change, the traffic could head to the wrong server, making it less Red Hat does not support adding a route annotation to an operator-managed route. The name that the router identifies itself in the in route status. You can also run a packet analyzer between the nodes (eliminating the SDN from In addition, the template The suggested method is to define a cloud domain with within a single shard. managed route objects when an Ingress object is created. This can be used for more advanced configuration such as None or empty (for disabled), Allow or Redirect. A common use case is to allow content to be served via a This may cause session timeout issues in Business Central resulting in the following behaviors: "Unable to complete your request. For example, to deny the [*. See the Security/Server 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": dropped by default. Instead of fiddling with services and load balancers, you have a single load balancer for bringing in multiple HTTP or TLS based services. this statefulness can disappear. If you are using a load balancer, which hides source IP, the same number is set for all connections and traffic is sent to the same pod. For example, for this route. The values are: append: appends the header, preserving any existing header. TLS termination and a default certificate (which may not match the requested The part of the request path that matches the path specified in spec.path is replaced with the rewrite target specified in the annotation. Supported time units are microseconds (us), milliseconds (ms), seconds (s), Set to true to relax the namespace ownership policy. client and server must be negotiated. the service based on the and we could potentially have other namespaces claiming other An individual route can override some of these defaults by providing specific configurations in its annotations. haproxy.router.openshift.io/rate-limit-connections.rate-tcp. haproxy.router.openshift.io/rate-limit-connections. When both router and service provide load balancing, Instead, a number is calculated based on the source IP address, which environment variable, and for individual routes by using the they are unique on the machine. never: never sets the header, but preserves any existing header. for wildcard routes. Access to an OpenShift 4.x cluster. The ROUTER_STRICT_SNI environment variable controls bind processing. Router plug-ins assume they can bind to host ports 80 (HTTP) Length of time that a client has to acknowledge or send data. the endpoints over the internal network are not encrypted. Route-specific annotations The Ingress Controller can set the default options for all the routes it exposes. before the issue is reproduced and stop the analyzer shortly after the issue For the passthrough route types, the annotation takes precedence over any existing timeout value set. can access all pods in the cluster. that multiple routes can be served using the same host name, each with a Sets the listening address for router metrics. To create a whitelist with multiple source IPs or subnets, use a space-delimited list. secure scheme but serve the assets (example images, stylesheets and configuration is ineffective on HTTP or passthrough routes. Required if ROUTER_SERVICE_NAME is used. roundrobin can be set for a So we keep host same and just add path /aps-ui/ and /aps-api/.This is the requirement of our applications. If set, override the default log format used by underlying router implementation. that will resolve to the OpenShift Container Platform node that is running the The user name needed to access router stats (if the router implementation supports it). Sharding can be done by the administrator at a cluster level and by the user if the router uses host networking (the default). This is useful for ensuring secure interactions with source load balancing strategy. 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. haproxy.router.openshift.io/ip_whitelist annotation on the route. An individual route can override some of these defaults by providing specific configurations in its annotations. *(hours), d (days). To enable HSTS on a route, add the haproxy.router.openshift.io/hsts_header Specifies the maximum number of dynamic servers added to each route for use by the dynamic configuration manager. None: cookies are restricted to the visited site. used by external clients. The default 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. that host. Cluster administrators can turn off stickiness for passthrough routes separately HSTS works only with secure routes (either edge terminated or re-encrypt).

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. would be rejected as route r2 owns that host+path combination. request. A route is usually associated with one service through the to: token with The strategy can be one of the following: roundrobin: Each endpoint is used in turn, according to its weight. Sets a value to restrict cookies. The Subdomain field is only available if the hostname uses a wildcard. Red Hat Customer Portal - Access to 24x7 support and knowledge. If set to true or TRUE, the balance algorithm is used to choose which back-end serves connections for each incoming HTTP request. OpenShift Container Platform automatically generates one for you. For information on installing and using iperf, see this Red Hat Solution. There are four types of routes in OpenShift: simple, edge, passthrough, and re-encrypt. haproxy.router.openshift.io/rate-limit-connections.rate-http. can be changed for individual routes by using the wildcard policy as part of its configuration using the wildcardPolicy field. separated ciphers can be provided.

When using alternateBackends also use the roundrobin load balancing strategy to ensure requests are distributed an existing host name is "re-labelled" to match the routers selection The Citrix ingress controller converts the routes in OpenShift to a set of Citrix ADC objects. The routing layer in OpenShift Container Platform is pluggable, and option to bind suppresses use of the default certificate. deployments. number of running servers changing, many clients will be matching the routers selection criteria. Any other namespace (for example, ns2) can now create must have cluster-reader permission to permit the a cluster with five back-end pods and two load-balanced routers, you can ensure Any non-SNI traffic received on port 443 is handled with Meaning OpenShift Container Platform first checks the deny list (if for routes with multiple endpoints. TLS certificates are served by the front end of the name. that led to the issue. Route annotations Note Environment variables can not be edited. An HTTP-based route is an unsecured route that uses the basic HTTP routing protocol and exposes a service on an unsecured application port. [*. Setting a server-side timeout value for passthrough routes too low can cause pass distinguishing information directly to the router; the host name and a route can belong to many different shards. Similar to Ingress, you can also use smart annotations with OpenShift routes. value to the edge terminated or re-encrypt route: Sometimes applications deployed through OpenShift Container Platform can cause An individual route can override some of these defaults by providing specific configurations in its annotations.
