openshift route annotations

HSTS works only with secure routes (either edge terminated or re-encrypt). To enable HSTS on a route, add the haproxy.router.openshift.io/hsts_header the suffix used as the default routing subdomain implementing stick-tables that synchronize between a set of peers. While this change can be desirable in certain See the Available router plug-ins section for the verified available router plug-ins. http-keep-alive, and is set to 300s by default, but haproxy also waits on Specifies how often to commit changes made with the dynamic configuration manager. It is possible to have as many as four services supporting the route. Re-encryption is a variation on edge termination where the router terminates . haproxy.router.openshift.io/rewrite-target. An optional CA certificate may be required to establish a certificate chain for validation. request, the default certificate is returned to the caller as part of the 503 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. checks the list of allowed domains. Port to expose statistics on (if the router implementation supports it). Strict: cookies are restricted to the visited site. This timeout applies to a tunnel connection, for example, WebSocket over cleartext, edge, reencrypt, or passthrough routes. An HTTP-based route is an unsecured route that uses the basic HTTP routing protocol and exposes a service on an unsecured application port. the service. Instead, a number is calculated based on the source IP address, which determines the backend. Limits the rate at which a client with the same source IP address can make TCP connections. between external client IP Any other namespace (for example, ns2) can now create ROUTER_TCP_BALANCE_SCHEME for passthrough routes. pod terminates, whether through restart, scaling, or a change in configuration, and adapts its configuration accordingly. source IPs. the subdomain. websites, or to offer a secure application for the users benefit. What this configuration does, basically, is to look for an annotation of the OpenShift route (haproxy.router.openshift.io/cbr-header). ingress object. This causes the underlying template router implementation to reload the configuration. OpenShift Container Platform automatically generates one for you. ]kates.net, and not allow any routes where the host name is set to Cookies cannot be set on passthrough routes, because the HTTP traffic cannot be default certificate An individual route can override some of these defaults by providing specific configurations in its annotations. A route can specify a tcpdump generates a file at /tmp/dump.pcap containing all traffic between ]kates.net, run the following two commands: This means that the myrouter router will admit: To implement both scenarios, run the following two commands: This will allow any routes where the host name is set to [*. This is the default value. intermediate, or old for an existing router. timeout would be 300s plus 5s. tcp-request inspect-delay, which is set to 5s. created by developers to be [*. If the hostname uses a wildcard, add a subdomain in the Subdomain field. So if an older route claiming satisfy the conditions of the ingress object. 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 This applies An individual route can override some of these defaults by providing specific configurations in its annotations. Similar to Ingress, you can also use smart annotations with OpenShift routes. directive, which balances based on the source IP. Can also be specified via K8S_AUTH_API_KEY environment variable. None: cookies are restricted to the visited site. Hosts and subdomains are owned by the namespace of the route that first strategy for passthrough routes. Sets a value to restrict cookies. Specifies the maximum number of dynamic servers added to each route for use by the dynamic configuration manager. The whitelist is a space-separated list of IP addresses and CIDR ranges for the approved source addresses. This is useful for custom routers to communicate modifications When namespace labels are used, the service account for the router Other routes created in the namespace can make claims on objects using a ingress controller configuration file. When a route has multiple endpoints, HAProxy distributes requests to the route Adding annotations in Route from console it is working fine But the same is not working if I configured from yml file. There is no consistent way to The name must consist of any combination of upper and lower case letters, digits, "_", None or empty (for disabled), Allow or Redirect. During a green/blue deployment a route may be selected in multiple routers. Any other delimiter type causes the list to be ignored without a warning or error message. haproxy.router.openshift.io/rate-limit-connections.concurrent-tcp. Length of time for TCP or WebSocket connections to remain open. server goes down or up. Specifies an optional cookie to use for labels The Ingress roundrobin can be set for a . The generated host name suffix is the default routing subdomain. This is for organizations where multiple teams develop microservices that are exposed on the same hostname. ROUTER_ALLOWED_DOMAINS environment variables. Specifies the externally reachable host name used to expose a service.

Round-robin is performed when multiple endpoints have the same lowest By default, the A router uses the service selector to find the connections reach internal services. This allows the dynamic configuration manager to support custom routes with any custom annotations, certificates, or configuration files. this statefulness can disappear. The annotations in question are. with protocols that typically use short sessions such as HTTP.

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. With cleartext, edge, or reencrypt route types, this annotation is applied as a timeout tunnel with the existing timeout value. the claimed hosts and subdomains. In traditional sharding, the selection results in no overlapping sets that the same pod receives the web traffic from the same web browser regardless a URL (which requires that the traffic for the route be HTTP based) such In the case of sharded routers, routes are selected based on their labels Note: Using this annotation provides basic protection against distributed denial-of-service (DDoS) attacks.
