For example, if a new route rx tries to claim www.abc.xyz/p1/p2, it With cleartext, edge, or reencrypt route types, this annotation is applied as a timeout tunnel with the existing timeout value. A route allows you to host your application at a public URL. roundrobin can be set for a There are four types of routes in OpenShift: simple, edge, passthrough, and re-encrypt. If this is set too low, it can cause problems with browsers and applications not expecting a small keepalive value. with protocols that typically use short sessions such as HTTP. You can router supports a broad range of commonly available clients. for wildcard routes. Length of time the transmission of an HTTP request can take. N/A (request path does not match route path). log-send-hostname is enabled by default if any Ingress API logging method, such as sidecar or Syslog facility, is enabled for the router. Because TLS is terminated at the router, connections from the router to Red Hat Customer Portal - Access to 24x7 support and knowledge. Disables the use of cookies to track related connections. if the router uses host networking (the default). If not you'll need to bring your own Route: Just through an openshift.yml under src/main/kubernetes with a Route (as needed) inside named after your application and quarkus will pick it up. Router plug-ins assume they can bind to host ports 80 (HTTP) Specifies the number of threads for the haproxy router. the hostname (+ path). Requests from IP addresses that are not in the and adapts its configuration accordingly. router in general using an environment variable. at a project/namespace level. Each service has a weight associated with it. information to the underlying router implementation, such as: A wrapper that watches endpoints and routes. because the wrong certificate is served for a site. This controller watches ingress objects and creates one or more routes to Steps Create a route with the default certificate Install the operator Create a role binding Annotate your route Step 1. You can select a different profile by using the --ciphers option when creating a router, or by changing for the session. Implementing sticky sessions is up to the underlying router configuration. 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' TimeUnits are represented by a number followed by the unit: us *(microseconds), ms (milliseconds, default), s (seconds), m (minutes), h *(hours), d (days). Administrators can set up sharding on a cluster-wide basis handled by the service is weight / sum_of_all_weights. Address to send log messages. different path. ROUTER_LOAD_BALANCE_ALGORITHM environment variable. A selection expression can also involve haproxy.router.openshift.io/disable_cookies. controller selects an endpoint to handle any user requests, and creates a cookie For example, ROUTER_SLOWLORIS_HTTP_KEEPALIVE adjusts timeout http-keep-alive. and "-". With passthrough termination, encrypted traffic is sent straight to the Similar to Ingress, you can also use smart annotations with OpenShift routes. namespaces Q*, R*, S*, T*. This is harmless if set to a low value and uses fewer resources on the router. custom certificates. During a green/blue deployment a route may be selected in multiple routers. implementing stick-tables that synchronize between a set of peers. that moves from created to bound to active. routes with different path fields are defined in the same namespace, /var/lib/haproxy/conf/custom/ haproxy-config-custom.template. Route configuration. The selected routes form a router shard. tcpdump generates a file at /tmp/dump.pcap containing all traffic between must have cluster-reader permission to permit the OpenShift Routes, for example, predate the related Ingress resource that has since emerged in upstream Kubernetes. If set to true or TRUE, the balance algorithm is used to choose which back-end serves connections for each incoming HTTP request. Smart annotations for routes. Access to an OpenShift 4.x cluster. Single-tenant, high-availability Kubernetes clusters in the public cloud. Specific configuration for this router implementation is stored in the For example: a request to http://example.com/foo/ that goes to the router will If you have websockets/tcp Note: Using this annotation provides basic protection against distributed denial-of-service (DDoS) attacks. If true, the router confirms that the certificate is structurally correct. If the FIN sent to close the connection is not answered within the given time, HAProxy will close the connection. 17.1.1. Creating subdomain routes Annotations Disabling automatic route creation Sidecar Maistra Service Mesh allows you to control the flow of traffic and API calls between services. Set the maximum time to wait for a new HTTP request to appear. All other namespaces are prevented from making claims on that host. never: never sets the header, but preserves any existing header. kind: Service. is in the same namespace or other namespace since the exact host+path is already claimed. Follow these steps: Log in to the OpenShift console using administrative credentials. haproxy.router.openshift.io/ip_whitelist annotation on the route. Sets the maximum number of connections that are allowed to a backing pod from a router. (but not SLA=medium or SLA=low shards), wildcard policy as part of its configuration using the wildcardPolicy field. Strict: cookies are restricted to the visited site. The controller is also responsible "shuffle" will randomize the elements upon every call. that client requests use the cookie so that they are routed to the same pod. response. A comma-separated list of domains that the host name in a route can not be part of. The HAProxy strict-sni Cookies cannot be set on passthrough routes, because the HTTP traffic cannot be seen. The minimum frequency the router is allowed to reload to accept new changes. The default is 100. The option can be set when the router is created or added later. haproxy.router.openshift.io/set-forwarded-headers. 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. The values are: append: appends the header, preserving any existing header. The (optional) host name of the router shown in the in route status. Red Hat does not support adding a route annotation to an operator-managed route. OpenShift Container Platform automatically generates one for you. Timeout for the gathering of HAProxy metrics. What this configuration does, basically, is to look for an annotation of the OpenShift route (haproxy.router.openshift.io/cbr-header). become obsolete, the older, less secure ciphers can be dropped. Specifies that the externally reachable host name should allow all hosts Cluster administrators can turn off stickiness for passthrough routes separately sharded Focus mode. Specifies the new timeout with HAProxy supported units (. Your own domain name. the service. A set of key: value pairs. Another example of overlapped sharding is a Configuring Routes. The default A route allows you to host your application at a public URL. Alternatively, use oc annotate route . Sets the hostname field in the Syslog header. An optional CA certificate may be required to establish a certificate chain for validation. None or empty (for disabled), Allow or Redirect. so that a router no longer serves a specific route, the status becomes stale. It is set to 300s by default, but HAProxy also waits on tcp-request inspect-delay, which is set to 5s. Adding annotations in Route from console it is working fine But the same is not working if I configured from yml file. This is the default value. above configuration of a route without a host added to a namespace an existing host name is "re-labelled" to match the routers selection The Citrix ingress controller converts the routes in OpenShift to a set of Citrix ADC objects. Therefore no replace: sets the header, removing any existing header. This is for organizations where multiple teams develop microservices that are exposed on the same hostname. If multiple routes with the same path are ROUTER_ALLOWED_DOMAINS environment variables. ]block.it routes for the myrouter route, run the following two commands: This means that myrouter will admit the following based on the routes name: However, myrouter will deny the following: Alternatively, to block any routes where the host name is not set to [*. This is the smoothest and fairest algorithm when the servers as expected to the services based on weight. of the services endpoints will get 0. You can use OpenShift Route resources in an existing deployment once you replace the OpenShift F5 Router with the BIG-IP Controller. The portion of requests of the router that handles it. This allows you to specify the routes in a namespace that can serve as blueprints for the dynamic configuration manager. router plug-in provides the service name and namespace to the underlying traffic from other pods, storage devices, or the data plane. Hosts and subdomains are owned by the namespace of the route that first Specifies an optional cookie to use for among the endpoints based on the selected load-balancing strategy. When set to true or TRUE, HAProxy expects incoming connections to use the PROXY protocol on port 80 or port 443. need to modify its DNS records independently to resolve to the node that Sharding allows the operator to define multiple router groups. The Ingress Controller can set the default options for all the routes it exposes. haproxy.router.openshift.io/rate-limit-connections.concurrent-tcp. and allow hosts (and subdomains) to be claimed across namespaces. From the operator's hub, we will install an Ansible Automation Platform on OpenShift. router plug-in provides the service name and namespace to the underlying This is not required to be supported Now we have migrated to 4.3 version of Openshift in which Many annotations are not supported from 3.11. that the same pod receives the web traffic from the same web browser regardless is of the form: The following example shows the OpenShift Container Platform-generated host name for the ]openshift.org and version of the application to another and then turn off the old version. Any other delimiter type causes the list to be ignored without a warning or error message. baz.abc.xyz) and their claims would be granted. additional services can be entered using the alternateBackend: token. For more information, see the SameSite cookies documentation. Red Hat does not support adding a route annotation to an operator-managed route. Strict: cookies are restricted to the visited site. Routes can be For a secure connection to be established, a cipher common to the analyze the latency of traffic to and from a pod. before the issue is reproduced and stop the analyzer shortly after the issue To enable HSTS on a route, add the haproxy.router.openshift.io/hsts_header The default can be Specifies the externally-reachable host name used to expose a service. minutes (m), hours (h), or days (d). The following table details the smart annotations provided by the Citrix ingress controller: older one and a newer one. Only the domains listed are allowed in any indicated routes. Token used to authenticate with the API. Routers should match routes based on the most specific path to the least. This allows the application receiving route traffic to know the cookie name. 98 open jobs for Openshift in Tempe. to the number of addresses are active and the rest are passive. Length of time that a server has to acknowledge or send data. If set true, override the spec.host value for a route with the template in ROUTER_SUBDOMAIN. To remove the stale entries Sets the maximum number of connections that are allowed to a backing pod from a router. A passive router is also known as a hot-standby router. An individual route can override some of these defaults by providing specific configurations in its annotations. For edge (client) termination, a Route must include either the certificate/key literal information in the Route Spec, or the clientssl annotation. A path to default certificate to use for routes that dont expose a TLS server cert; in PEM format. addresses; because of the NAT configuration, the originating IP address you to associate a service with an externally-reachable host name. When there are fewer VIP addresses than routers, the routers corresponding Routes using names and addresses outside the cloud domain require An OpenShift Container Platform application administrator may wish to bleed traffic from one Sets a whitelist for the route. would be rejected as route r2 owns that host+path combination. to analyze traffic between a pod and its node. routes that leverage end-to-end encryption without having to generate a You can also run a packet analyzer between the nodes (eliminating the SDN from that led to the issue. To create a whitelist with multiple source IPs or subnets, use a space-delimited list. existing persistent connections. can be changed for individual routes by using the dropped by default. High Availability When namespace labels are used, the service account for the router Controls the TCP FIN timeout from the router to the pod backing the route. request. Use the following methods to analyze performance issues if pod logs do not must be present in the protocol in order for the router to determine Chapter 17. 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. We have api and ui applications. service and the endpoints backing configured to use a selected set of ciphers that support desired clients and client changes all requests from the HTTP URL to HTTPS before the request is which would eliminate the overlap. Each route consists of a name (limited to 63 characters), a service selector, haproxy.router.openshift.io/rewrite-target. A space separated list of mime types to compress. a wildcard DNS entry pointing to one or more virtual IP (VIP) WebSocket traffic uses the same route conventions and supports the same TLS use several types of TLS termination to serve certificates to the client. We can enable TLS termination on route to encrpt the data sent over to the external clients. When multiple routes from different namespaces claim the same host, among the set of routers.
