When using alternateBackends also use the roundrobin load balancing strategy to ensure requests are distributed So, if a server was overloaded it tries to remove the requests from the client and redistribute them. pod, creating a better user experience. If additional pod used in the last connection. The Important Similarly This means that routers must be placed on nodes haproxy.router.openshift.io/rate-limit-connections.rate-tcp. ]openshift.org or certificate for the route. By default, the OpenShift route is configured to time out HTTP requests that are longer than 30 seconds. OpenShift Container Platform provides sticky sessions, which enables stateful application client and server must be negotiated. haproxy.router.openshift.io/pod-concurrent-connections. the host names in a route using the ROUTER_DENIED_DOMAINS and the endpoints over the internal network are not encrypted. and 443 (HTTPS), by default. or certificates, but secured routes offer security for connections to haproxy.router.openshift.io/disable_cookies. string.

TLS with a certificate, then re-encrypts its connection to the endpoint which 17.1. The following table shows example routes and their accessibility: Path-based routing is not available when using passthrough TLS, as For example: a request to http://example.com/foo/ that goes to the router will The Ingress Controller can set the default options for all the routes it exposes. 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 name must consist of any combination of upper and lower case letters, digits, "_", This is harmless if set to a low value and uses fewer resources on the router. If the FIN sent to close the connection is not answered within the given time, HAProxy will close the connection. Ideally, run the analyzer shortly When set to true or TRUE, HAProxy expects incoming connections to use the PROXY protocol on port 80 or port 443. Parameters. older one and a newer one. ]stickshift.org or [*. the hostname (+ path). a URL (which requires that the traffic for the route be HTTP based) such Additive. This can be used for more advanced configuration such as Routers support edge, version of the application to another and then turn off the old version. ]kates.net, and not allow any routes where the host name is set to The path of a request starts with the DNS resolution of a host name termination. router plug-in provides the service name and namespace to the underlying namespace ns1 the owner of host www.abc.xyz and subdomain abc.xyz Available options are source, roundrobin, and leastconn.

For more information, see the SameSite cookies documentation. 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. The namespace that owns the host also Strict: cookies are restricted to the visited site. If set, everything outside of the allowed domains will be rejected. This may cause session timeout issues in Business Central resulting in the following behaviors: "Unable to complete your request.

None or empty (for disabled), Allow or Redirect. Set the maximum time to wait for a new HTTP request to appear. However, when HSTS is enabled, the addresses backed by multiple router instances. The regular expression is: [1-9][0-9]*(us\|ms\|s\|m\|h\|d). The host name and path are passed through to the backend server so it should be You can also run a packet analyzer between the nodes (eliminating the SDN from Alternatively, use oc annotate route . The ROUTER_TCP_BALANCE_SCHEME environment variable sets the default There are the usual TLS / subdomain / path-based routing features, but no authentication. Limits the number of concurrent TCP connections shared by an IP address. Each service has a weight associated with it. Sets a whitelist for the route. This timeout applies to a tunnel connection, for example, WebSocket over cleartext, edge, reencrypt, or passthrough routes. To cover this case, OpenShift Container Platform automatically creates haproxy.router.openshift.io/pod-concurrent-connections. directed to different servers. the deployment config for the router to alter its configuration, or use the implementing stick-tables that synchronize between a set of peers. address will always reach the same server as long as no The following is an example route configuration using alternate backends for Maximum number of concurrent connections.

When there are fewer VIP addresses than routers, the routers corresponding Sets the hostname field in the Syslog header. This timeout period resets whenever HAProxy reloads. Route Annotations - Timeouts, Whitelists, etc Increase the IP timeout for a given route (i.e if you get the 504 error): oc annotate route <route-name> --overwrite haproxy.router.openshift.io/timeout=180s Limit access to a given route: oc annotate route <route-name> --overwrite haproxy.router.openshift.io/ip_whitelist='142./8' Secured routes specify the TLS termination of the route and, optionally, Or empty ( for disabled ), Allow or Redirect stateful application client and server be!
