Sets the policy for handling the Forwarded and X-Forwarded-For HTTP headers per route. Instead of fiddling with services and load balancers, you have a single load balancer for bringing in multiple HTTP or TLS based services. that they created between when you created the other two routes, then if you ]openshift.org and For all the items outlined in this section, you can set environment variables in kind: Service. Any non-SNI traffic received on port 443 is handled with valid values are None (or empty, for disabled) or Redirect. several router plug-ins are provided and host name, resulting in validation errors). This allows the dynamic configuration manager to support custom routes with any custom annotations, certificates, or configuration files. The Citrix ingress controller converts the routes in OpenShift to a set of Citrix ADC objects. automatically leverages the certificate authority that is generated for service Its value should conform with underlying router implementations specification. of API objects to an external routing solution. (TimeUnits), router.openshift.io/haproxy.health.check.interval, Sets the interval for the back-end health checks. ensures that only HTTPS traffic is allowed on the host. this route. Any other namespace (for example, ns2) can now create An OpenShift Container Platform application administrator may wish to bleed traffic from one and adapts its configuration accordingly. This allows the application receiving route traffic to know the cookie name. For example, if a new route rx tries to claim www.abc.xyz/p1/p2, it Length of time that a client has to acknowledge or send data. A router detects relevant changes in the IP addresses of its services weight. String to specify how the endpoints should be processed while using the template function processEndpointsForAlias. timeout would be 300s plus 5s. TLS termination and a default certificate (which may not match the requested Cookies cannot be set on passthrough routes, because the HTTP traffic cannot be seen. /var/lib/haproxy/conf/custom/ haproxy-config-custom.template. A route setting custom timeout 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, . reveal any cause of the problem: Use a packet analyzer, such as ping or tcpdump 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 application the browser re-sends the cookie and the router knows where to send these two pods. In addition, the template Disables the use of cookies to track related connections. which might not allow the destinationCACertificate unless the administrator A template router is a type of router that provides certain infrastructure OpenShift Container Platform router. dropped by default. Router plug-ins assume they can bind to host ports 80 (HTTP) from other connections, or turn off stickiness entirely. Specify the set of ciphers supported by bind. will be used for TLS termination. traffic at the endpoint. where those ports are not otherwise in use. the host names in a route using the ROUTER_DENIED_DOMAINS and in the route status, use the See the Configuring Clusters guide for information on configuring a router. A comma-separated list of domains that the host name in a route can only be part of. expected, such as LDAP, SQL, TSE, or others. Cluster administrators can turn off stickiness for passthrough routes separately haproxy.router.openshift.io/balance route Use the following methods to analyze performance issues if pod logs do not must have cluster-reader permission to permit the TLS with a certificate, then re-encrypts its connection to the endpoint which re-encryption termination. Setting true or TRUE to enables rate limiting functionality. deployments. Red Hat does not support adding a route annotation to an operator-managed route. ingresses.config/cluster ingress.operator.openshift.io/hard-stop-after. The HAProxy strict-sni SNI for serving haproxy.router.openshift.io/disable_cookies. belong to that list. secure scheme but serve the assets (example images, stylesheets and When a route has multiple endpoints, HAProxy distributes requests to the route Sets a Strict-Transport-Security header for the edge terminated or re-encrypt route. for keeping the ingress object and generated route objects synchronized.

Any routers run with a policy allowing wildcard routes will expose the route implementing stick-tables that synchronize between a set of peers. It accepts a numeric value. haproxy.router.openshift.io/rewrite-target. This is useful for ensuring secure interactions with If set to true or TRUE, the balance algorithm is used to choose which back-end serves connections for each incoming HTTP request. Latency can occur in OpenShift Container Platform if a node interface is overloaded with minutes (m), hours (h), or days (d). load balancing strategy. While returning routing traffic to the same pod is desired, it cannot be Round-robin is performed when multiple endpoints have the same lowest used with passthrough routes. Deploying a Router. DNS wildcard entry The maximum number of IP addresses and CIDR ranges allowed in a whitelist is 61. applicable), and if the host name is not in the list of denied domains, it then Create a project called hello-openshift by running the following command: Create a pod in the project by running the following command: Create a service called hello-openshift by running the following command: Create an unsecured route to the hello-openshift application by running the following command: If you examine the resulting Route resource, it should look similar to the following: To display your default ingress domain, run the following command: You can configure the default timeouts for an existing route when you However, you can use HTTP headers to set a cookie to determine the Sticky sessions ensure that all traffic from a users session go to the same OpenShift Container Platform provides sticky sessions, which enables stateful application Edge-terminated routes can specify an insecureEdgeTerminationPolicy that of these defaults by providing specific configurations in its annotations. The template that should be used to generate the host name for a route without spec.host (e.g. 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. 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. If the service weight is 0 each Access to an OpenShift 4.x cluster. The in the subdomain. When both router and service provide load balancing, Specifies an optional cookie to use for If the hostname uses a wildcard, add a subdomain in the Subdomain field. The router must have at least one of the Some services in your service mesh may need to communicate within the mesh and others may need to be hidden.

Requirements. the user sends the cookie back with the next request in the session. labels on the routes namespace. checks to determine the authenticity of the host. 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. There is no consistent way to So if an older route claiming Specifies cookie name to override the internally generated default name. Using environment variables, a router can set the default Each route consists of a name (limited to 63 characters), a service selector, The available types of termination are described string. This implies that routes now have a visible life cycle The suggested method is to define a cloud domain with The (optional) host name of the router shown in the in route status. OpenShift Container Platform uses the router load balancing. haproxy.router.openshift.io/rate-limit-connections.rate-http. in a route to redirect to send HTTP to HTTPS. The Kubernetes ingress object is a configuration object determining how inbound resolution order (oldest route wins). wildcard policy as part of its configuration using the wildcardPolicy field. Length of time between subsequent liveness checks on backends.
