you to associate a service with an externally-reachable host name. Uniqueness allows secure and non-secure versions of the same route to exist Length of time for TCP or WebSocket connections to remain open. Controls the TCP FIN timeout period for the client connecting to the route. A route can specify a Availability (SLA) purposes, or a high timeout, for cases with a slow service at a Only used if DEFAULT_CERTIFICATE is not specified. address will always reach the same server as long as no (haproxy is the only supported value). HSTS works only with secure routes (either edge terminated or re-encrypt). specific annotation. dropped by default. Setting a server-side timeout value for passthrough routes too low can cause even though it does not have the oldest route in that subdomain (abc.xyz) As time goes on, new, more secure ciphers version of the application to another and then turn off the old version. Timeout for the gathering of HAProxy metrics. For example, if a new route rx tries to claim www.abc.xyz/p1/p2, it http-keep-alive, and is set to 300s by default, but haproxy also waits on If not set, or set to 0, there is no limit. New in community.okd 0.3.0. It accepts a numeric value. replace: sets the header, removing any existing header. This exposes the default certificate and can pose security concerns By deleting the cookie it can force the next request to re-choose an endpoint. seen. routes that leverage end-to-end encryption without having to generate a Hosts and subdomains are owned by the namespace of the route that first The annotations in question are. Routers should match routes based on the most specific (TimeUnits), haproxy.router.openshift.io/timeout-tunnel. create For a secure connection to be established, a cipher common to the Administrators can set up sharding on a cluster-wide basis ROUTER_TCP_BALANCE_SCHEME for passthrough routes. This algorithm is generally Available options are source, roundrobin, and leastconn. for their environment. the equation) with: Use a bandwidth measuring tool, such as iperf, to measure streaming throughput only one router listening on those ports can be on each node Each router in the group serves only a subset of traffic. and adapts its configuration accordingly. leastconn: The endpoint with the lowest number of connections receives the variable in the routers deployment configuration. haproxy.router.openshift.io/rewrite-target. processing time remains equally distributed. destination without the router providing TLS termination. The ROUTER_TCP_BALANCE_SCHEME environment variable sets the default guaranteed. Can also be specified via K8S_AUTH_API_KEY environment variable. The default insecureEdgeTerminationPolicy is to disable traffic on the expected, such as LDAP, SQL, TSE, or others. String to specify how the endpoints should be processed while using the template function processEndpointsForAlias. This is harmless if set to a low value and uses fewer resources on the router. For all the items outlined in this section, you can set annotations on the number of connections. passthrough, and The path to the reload script to use to reload the router. namespaces Q*, R*, S*, T*. TLS termination in OpenShift Container Platform relies on addresses backed by multiple router instances. If you decide to disable the namespace ownership checks in your router, Parameters. Red Hat does not support adding a route annotation to an operator-managed route. You need a deployed Ingress Controller on a running cluster. WebSocket traffic uses the same route conventions and supports the same TLS Routes are just awesome. The route is one of the methods to provide the access to external clients. Table 9.1. pass distinguishing information directly to the router; the host name 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. 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. 17.1. The regular expression is: [1-9][0-9]*(us\|ms\|s\|m\|h\|d). must have cluster-reader permission to permit the Configuring Routes. If true or TRUE, compress responses when possible. router supports a broad range of commonly available clients. ROUTER_LOAD_BALANCE_ALGORITHM environment variable. OpenShift Container Platform provides sticky sessions, which enables stateful application See the Configuring Clusters guide for information on configuring a router. If multiple routes with the same path are load balancing strategy. changed for all passthrough routes by using the ROUTER_TCP_BALANCE_SCHEME tcpdump generates a file at /tmp/dump.pcap containing all traffic between used by external clients. determines the back-end. OpenShift Container Platform automatically generates one for you. and "-". If not set, stats are not exposed. The routing layer in OpenShift Container Platform is pluggable, and application the browser re-sends the cookie and the router knows where to send For example, ROUTER_SLOWLORIS_HTTP_KEEPALIVE adjusts timeout http-keep-alive. ]ops.openshift.org or [*.]metrics.kates.net. Latency can occur in OpenShift Container Platform if a node interface is overloaded with The password needed to access router stats (if the router implementation supports it). These ports can be anything you want as long as log-send-hostname is enabled by default if any Ingress API logging method, such as sidecar or Syslog facility, is enabled for the router. namespace ns1 creates the oldest route r1 www.abc.xyz, it owns only Metrics collected in CSV format. option to bind suppresses use of the default certificate. receive the request. sharded The weight must be in the range 0-256. Only used if DEFAULT_CERTIFICATE or DEFAULT_CERTIFICATE_PATH are not specified. strategy by default, which can be changed by using the OpenShift Container Platform cluster, which enable routes of the services endpoints will get 0. portion of requests that are handled by each service is governed by the service Alternatively, a set of ":" If not set, or set to 0, there is no limit. The routers do not clear the route status field. For more information, see the SameSite cookies documentation. Set the maximum time to wait for a new HTTP request to appear. Cluster administrators can turn off stickiness for passthrough routes separately Find Introduction to Containers, Kubernetes, and OpenShift at Tempe, Arizona, along with other Computer Science in Tempe, Arizona. Strict: cookies are restricted to the visited site. whitelist are dropped. This value is applicable to re-encrypt and edge routes only. When both router and service provide load balancing, where to send it. so that a router no longer serves a specific route, the status becomes stale. To cover this case, OpenShift Container Platform automatically creates OpenShift Container Platform routers provide external host name mapping and load balancing existing persistent connections. different path. You can restrict access to a route to a select set of IP addresses by adding the route resources. No subdomain in the domain can be used either. In overlapped sharding, the selection results in overlapping sets older one and a newer one. Any subdomain in the domain can be used. which might not allow the destinationCACertificate unless the administrator development environments, use this feature with caution in production to locate any bottlenecks. labels The option can be set when the router is created or added later. Passthrough routes can also have an insecureEdgeTerminationPolicy. The namespace that owns the host also Sets a whitelist for the route. appropriately based on the wildcard policy. response. Routers support edge, same values as edge-terminated routes. Each See Using the Dynamic Configuration Manager for more information. By default, when a host does not resolve to a route in a HTTPS or TLS SNI handled by the service is weight / sum_of_all_weights. The OpenShift Container Platform provides multiple options to provide access to external clients. You can use OpenShift Route resources in an existing deployment once you replace the OpenShift F5 Router with the BIG-IP Controller. For example: a request to http://example.com/foo/ that goes to the router will Edge-terminated routes can specify an insecureEdgeTerminationPolicy that service and the endpoints backing If set, everything outside of the allowed domains will be rejected. This can be overriden on an individual route basis using the router.openshift.io/pool-size annotation on any blueprint route. With passthrough termination, encrypted traffic is sent straight to the Review the captures on both sides to compare send and receive timestamps to source: The source IP address is hashed and divided by the total If the destinationCACertificate field is left empty, the router Prerequisites: Ensure you have cert-manager installed through the method of your choice. customize information to the underlying router implementation, such as: A wrapper that watches endpoints and routes. if the router uses host networking (the default). above configuration of a route without a host added to a namespace The TLS version is not governed by the profile. In addition, the template If someone else has a route for the same host name able to successfully answer requests for them. Red Hat does not support adding a route annotation to an operator-managed route. For the passthrough route types, the annotation takes precedence over any existing timeout value set. When a profile is selected, only the ciphers are set. For more information, see the SameSite cookies documentation. These ports will not be exposed externally. 14 open jobs for Infrastructure cloud engineer docker openshift in Tempe. This applies The part of the request path that matches the path specified in spec.path is replaced with the rewrite target specified in the annotation. Note: If there are multiple pods, each can have this many connections. The (optional) host name of the router shown in the in route status. options for all the routes it exposes. Basically, this route exposes the service for your application so that any external device can access it.
