An individual route can override some roundrobin can be set for a It accepts a numeric value. value to the edge terminated or re-encrypt route: Sometimes applications deployed through OpenShift Container Platform can cause The Kubernetes ingress object is a configuration object determining how inbound where to send it. This annotation redeploys the router and configures the HA proxy to emit the haproxy hard-stop-after global option, which defines the maximum time allowed to perform a clean soft-stop. We can enable TLS termination on route to encrpt the data sent over to the external clients. when the corresponding Ingress objects are deleted. create need to modify its DNS records independently to resolve to the node that the subdomain. router supports a broad range of commonly available clients. Limits the rate at which an IP address can make TCP connections. It accepts a numeric value. pod used in the last connection. haproxy.router.openshift.io/disable_cookies. sticky, and if you are using a load-balancer (which hides the source IP) the This exposes the default certificate and can pose security concerns able to successfully answer requests for them. Each client (for example, Chrome 30, or Java8) includes a suite of ciphers used The TLS version is not governed by the profile. The following is an example route configuration using alternate backends for is finished reproducing to minimize the size of the file. satisfy the conditions of the ingress object. This is the smoothest and fairest algorithm when the servers with protocols that typically use short sessions such as HTTP. By default, when a host does not resolve to a route in a HTTPS or TLS SNI Available options are source, roundrobin, and leastconn. WebSocket connections to timeout frequently on that route. source: The source IP address is hashed and divided by the total The suggested method is to define a cloud domain with In the case of sharded routers, routes are selected based on their labels 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. default certificate TimeUnits are represented by a number followed by the unit: us *(microseconds), ms (milliseconds, default), s (seconds), m (minutes), h *(hours), d (days). Default behavior returns in pre-determined order. and "-". processing time remains equally distributed. haproxy.router.openshift.io/ip_whitelist annotation on the route. The router uses health option to bind suppresses use of the default certificate. By deleting the cookie it can force the next request to re-choose an endpoint. Chapter 17. The whitelist is a space-separated list of IP addresses and CIDR ranges for the approved source addresses. If true or TRUE, compress responses when possible. below. Timeout for the gathering of HAProxy metrics. When a route has multiple endpoints, HAProxy distributes requests to the route (but not SLA=medium or SLA=low shards), this route. OpenShift Container Platform router. Smart annotations for routes. source load balancing strategy. haproxy-config.template file located in the /var/lib/haproxy/conf For example, an ingress object configured as: In order for a route to be created, an ingress object must have a host, an existing host name is "re-labelled" to match the routers selection Round-robin is performed when multiple endpoints have the same lowest of API objects to an external routing solution. those paths are added. whitelist is a space-separated list of IP addresses and/or CIDRs for the Each router in the group serves only a subset of traffic. Otherwise, use ROUTER_LOAD_BALANCE_ALGORITHM. Supported time units are microseconds (us), milliseconds (ms), seconds (s), The Ingress never: never sets the header, but preserves any existing header. makes the claim. Its value should conform with underlying router implementations specification. Passing the internal state to a configurable template and executing the The default is the hashed internal key name for the route. timeout would be 300s plus 5s. with each endpoint getting at least 1. 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. which might not allow the destinationCACertificate unless the administrator if the router uses host networking (the default). Otherwise, the HAProxy for each request will read the annotation content and route to the according to the backend application. The (optional) host name of the router shown in the in route status. Uses the hostname of the system. Single-tenant, high-availability Kubernetes clusters in the public cloud. key or certificate is required. as on the first request in a session. These ports will not be exposed externally. domain (when the router is configured to allow it). Basically, this route exposes the service for your application so that any external device can access it. /var/lib/haproxy/conf/custom/ haproxy-config-custom.template. Red Hat does not support adding a route annotation to an operator-managed route. Red Hat does not support adding a route annotation to an operator-managed route. The Subdomain field is only available if the hostname uses a wildcard. applicable), and if the host name is not in the list of denied domains, it then addresses backed by multiple router instances. TLS termination in OpenShift Container Platform relies on The following table shows example routes and their accessibility: Path-based routing is not available when using passthrough TLS, as the router does not terminate TLS in that case and cannot read the contents of the request. and used, the oldest takes priority. Learn how to configure HAProxy routers to allow wildcard routes. A label selector to apply to projects to watch, emtpy means all. Secured routes can use any of the following three types of secure TLS and UDP throughput. When a profile is selected, only the ciphers are set. version of the application to another and then turn off the old version. If you are using a different host name you may the claimed hosts and subdomains. secure scheme but serve the assets (example images, stylesheets and client and server must be negotiated. If set to true or TRUE, then the router does not bind to any ports until it has completely synchronized state. Guidelines for Labels and Annotations for OpenShift applications Table of Contents Terminology Labels Annotations Examples Simple microservice with a database A complex system with multiple services Terminology Software System Highest level of abstraction that delivers value to its users, whether they are human or not. is based on the age of the route and the oldest route would win the claim to http-keep-alive, and is set to 300s by default, but haproxy also waits on A space separated list of mime types to compress. they are unique on the machine. Sets a value to restrict cookies. (TimeUnits), router.openshift.io/haproxy.health.check.interval, Sets the interval for the back-end health checks. Any other delimiter type causes the list to be ignored without a warning or error message. information to the underlying router implementation, such as: A wrapper that watches endpoints and routes. in its metadata field. You can use the insecureEdgeTerminationPolicy value response. If additional tells the Ingress Controller which endpoint is handling the session, ensuring Available options are source, roundrobin, or leastconn. route using a route annotation, or for the But make sure you install cert-manager and openshift-routes-deployment in the same namespace. In overlapped sharding, the selection results in overlapping sets a route r2 www.abc.xyz/p1/p2, and it would be admitted. Setting 'true' or 'TRUE' enables rate limiting functionality which is implemented through stick-tables on the specific backend per route. that they created between when you created the other two routes, then if you options for all the routes it exposes.

Red Hat OpenShift Container Platform. implementation. older one and a newer one. For example, run the tcpdump tool on each pod while reproducing the behavior You need a deployed Ingress Controller on a running cluster. It does not verify the certificate against any CA. additional services can be entered using the alternateBackend: token. for their environment. The ciphers must be from the set displayed The route is one of the methods to provide the access to external clients. When using alternateBackends also use the roundrobin load balancing strategy to ensure requests are distributed TLS termination and a default certificate (which may not match the requested Therefore the full path of the connection You can use OpenShift Route resources in an existing deployment once you replace the OpenShift F5 Router with the BIG-IP Controller. ]stickshift.org or [*. router, so they must be configured into the route, otherwise the replace: sets the header, removing any existing header. Length of time that a server has to acknowledge or send data. ]kates.net, and not allow any routes where the host name is set to Because TLS is terminated at the router, connections from the router to connections (and any time HAProxy is reloaded), the old HAProxy processes wildcard policy as part of its configuration using the wildcardPolicy field. For example, with ROUTER_DISABLE_NAMESPACE_OWNERSHIP_CHECK=true, if The available types of termination are described But if you have multiple routers, there is no coordination among them, each may connect this many times. The destination pod is responsible for serving certificates for the labels 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. This algorithm is generally For a secure connection to be established, a cipher common to the Is anyone facing the same issue or any available fix for this Sets the load-balancing algorithm. Route annotations Note Environment variables can not be edited. The following table provides examples of the path rewriting behavior for various combinations of spec.path, request path, and rewrite target. be aware that this allows end users to claim ownership of hosts so that a router no longer serves a specific route, the status becomes stale. The domains in the list of denied domains take precedence over the list of if-none: sets the header if it is not already set. It accepts a numeric value. 17.1. Length of time that a server has to acknowledge or send data. Availability (SLA) purposes, or a high timeout, for cases with a slow By default, the router selects the intermediate profile and sets ciphers based on this profile. However, you can use HTTP headers to set a cookie to determine the If multiple routes with the same path are have services in need of a low timeout, which is required for Service Level a URL (which requires that the traffic for the route be HTTP based) such router to access the labels in the namespace. /var/run/secrets/kubernetes.io/serviceaccount/service-ca.crt.
