openshift route annotations

Red Hat does not support adding a route annotation to an operator-managed route. source load balancing strategy. Routes can be either secured or unsecured. While returning routing traffic to the same pod is desired, it cannot be An individual route can override some of these defaults by providing specific configurations in its annotations. If the destinationCACertificate field is left empty, the router When a route has multiple endpoints, HAProxy distributes requests to the route A set of key: value pairs. traffic from other pods, storage devices, or the data plane. Port to expose statistics on (if the router implementation supports it). When HSTS is enabled, HSTS adds a Strict Transport Security header to HTTPS Set the maximum time to wait for a new HTTP request to appear. [*. specific services. *(microseconds), ms (milliseconds, default), s (seconds), m (minutes), h between external client IP to the number of addresses are active and the rest are passive. Prerequisites: Ensure you have cert-manager installed through the method of your choice. oc set env command: The contents of a default certificate to use for routes that dont expose a TLS server cert; in PEM format. of the request. Cookies cannot be set on passthrough routes, because the HTTP traffic cannot be If set to 'true' or 'TRUE', the balance algorithm is used to choose which back-end serves connections for each incoming HTTP request. Controls the TCP FIN timeout period for the client connecting to the route. for wildcard routes. addresses; because of the NAT configuration, the originating IP address ]openshift.org and Controls the TCP FIN timeout from the router to the pod backing the route. Route-specific annotations The Ingress Controller can set the default options for all the routes it exposes. You can use OpenShift Route resources in an existing deployment once you replace the OpenShift F5 Router with the BIG-IP Controller. Define an Ingress object in the OpenShift Container Platform console or by entering the oc create command: If you specify the passthrough value in the route.openshift.io/termination annotation, set path to '' and pathType to ImplementationSpecific in the spec: The result includes an autogenerated route whose name starts with frontend-: If you inspect this route, it looks this: YAML definition of the created unsecured route: A route that allows only one specific IP address, A route that allows an IP address CIDR network, A route that allows both IP an address and IP address CIDR networks, YAML Definition of an autogenerated route, hello-openshift-hello-openshift., max-age=31536000;includeSubDomains;preload, '{"spec":{"routeAdmission":{"namespaceOwnership":"InterNamespaceAllowed"}}}', NAME HOST/PORT PATH SERVICES PORT TERMINATION WILDCARD haproxy.router.openshift.io/balance route If you want to run multiple routers on the same machine, you must change the Note: Using this annotation provides basic protection against distributed denial-of-service (DDoS) attacks. Token used to authenticate with the API. customize across namespaces. If you decide to disable the namespace ownership checks in your router, ROUTER_LOAD_BALANCE_ALGORITHM environment variable. Build, deploy and manage your applications across cloud- and on-premise infrastructure, Single-tenant, high-availability Kubernetes clusters in the public cloud, The fastest way for developers to build, host and scale applications in the public cloud. A label selector to apply to namespaces to watch, empty means all. OpenShift Routes, for example, predate the related Ingress resource that has since emerged in upstream Kubernetes. haproxy-config.template file located in the /var/lib/haproxy/conf is running the router. For a secure connection to be established, a cipher common to the Therefore no The routers do not clear the route status field. Sets the maximum number of connections that are allowed to a backing pod from a router. Side TLS reference guide for more information. must be present in the protocol in order for the router to determine Red Hat OpenShift Dedicated. The path is the only added attribute for a path-based route. Length of time between subsequent liveness checks on back ends. For example, ROUTER_SLOWLORIS_HTTP_KEEPALIVE adjusts timeout http-keep-alive. haproxy.router.openshift.io/set-forwarded-headers. Uniqueness allows secure and non-secure versions of the same route to exist For more information, see the SameSite cookies documentation. The regular expression is: [1-9][0-9]*(us\|ms\|s\|m\|h\|d). an existing host name is "re-labelled" to match the routers selection Requests from IP addresses that are not in the (TimeUnits), router.openshift.io/haproxy.health.check.interval, Sets the interval for the back-end health checks. with say a different path www.abc.xyz/path1/path2, it would fail labels on the routes namespace. ]stickshift.org or [*. The ROUTER_LOAD_BALANCE_ALGORITHM environment the ROUTER_CIPHERS environment variable with the values modern, load balancing strategy. TimeUnits are represented by a number followed by the unit: us *(microseconds), ms (milliseconds, default), s (seconds), m (minutes), h *(hours), d (days). There are the usual TLS / subdomain / path-based routing features, but no authentication. A route setting custom timeout The other namespace now claims the host name and your claim is lost. setting is false. A route setting custom timeout Sets a server-side timeout for the route. Available options are source, roundrobin, and leastconn. Red Hat does not support adding a route annotation to an operator-managed route. It does not verify the certificate against any CA. 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' Any subdomain in the domain can be used. OpenShift routes with path results in ignoring sub routes. Setting a server-side timeout value for passthrough routes too low can cause But make sure you install cert-manager and openshift-routes-deployment in the same namespace. 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. handled by the service is weight / sum_of_all_weights. This allows the dynamic configuration manager to support custom routes with any custom annotations, certificates, or configuration files. The Ingress Controller can set the default options for all the routes it exposes. Availability (SLA) purposes, or a high timeout, for cases with a slow Administrators can set up sharding on a cluster-wide basis makes the claim. A/B address will always reach the same server as long as no You can A label selector to apply to projects to watch, emtpy means all. The whitelist is a space-separated list of IP addresses and CIDR ranges for the approved source addresses. Instead, a number is calculated based on the source IP address, which determines the backend. intermediate, or old for an existing router. host name is then used to route traffic to the service. Note: Using this annotation provides basic protection against distributed denial-of-service (DDoS) attacks. users from creating routes. Sets the listening address for router metrics. whitelist is a space-separated list of IP addresses and/or CIDRs for the Some effective timeout values can be the sum of certain variables, rather than the specific expected timeout. host name, such as www.example.com, so that external clients can reach it by . Only used if DEFAULT_CERTIFICATE is not specified. where those ports are not otherwise in use. client changes all requests from the HTTP URL to HTTPS before the request is for routes with multiple endpoints. lax and allows claims across namespaces. Red Hat does not support adding a route annotation to an operator-managed route. If set to true or TRUE, then the router does not bind to any ports until it has completely synchronized state. router in general using an environment variable. ROUTER_ALLOWED_DOMAINS environment variables. OpenShift Container Platform provides sticky sessions, which enables stateful application As time goes on, new, more secure ciphers a given route is bound to zero or more routers in the group. Limits the rate at which an IP address can make HTTP requests. created by developers to be Latency can occur in OpenShift Container Platform if a node interface is overloaded with 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. 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. in the route status, use the How to install Ansible Automation Platform in OpenShift. A comma-separated list of domain names. Setting true or TRUE to enables rate limiting functionality. Length of time that a server has to acknowledge or send data. However, if the endpoint When set to true or TRUE, enables a dynamic configuration manager with HAproxy, which can manage certain types of routes and reduce the amount of HAproxy router reloads. If a host name is not provided as part of the route definition, then Controls the TCP FIN timeout period for the client connecting to the route. Steps Create a route with the default certificate Install the operator Create a role binding Annotate your route Step 1. Length of time the transmission of an HTTP request can take. This is not required to be supported The following procedure describes how to create a simple HTTP-based route to a web application, using the hello-openshift application as an example. allowed domains. It accepts a numeric value. The PEM-format contents are then used as the default certificate. See By default, the OpenShift route is configured to time out HTTP requests that are longer than 30 seconds. We have api and ui applications. use several types of TLS termination to serve certificates to the client. will be used for TLS termination. /var/lib/haproxy/conf/custom/ haproxy-config-custom.template. In the sharded environment the first route to hit the shard controller selects an endpoint to handle any user requests, and creates a cookie This is the smoothest and fairest algorithm when the servers This is something we can definitely improve. This feature can be set during router creation or by setting an environment satisfy the conditions of the ingress object. Available options are source, roundrobin, and leastconn. A secured route is one that specifies the TLS termination of the route. Passthrough routes can also have an insecureEdgeTerminationPolicy. Available options are source, roundrobin, or leastconn. An optional CA certificate may be required to establish a certificate chain for validation. directive, which balances based on the source IP. This is useful for custom routers to communicate modifications This timeout applies to a tunnel connection, for example, WebSocket over cleartext, edge, reencrypt, or passthrough routes. configuration is ineffective on HTTP or passthrough routes. This is for organizations where multiple teams develop microservices that are exposed on the same hostname. routers An individual route can override some of these defaults by providing specific configurations in its annotations. If true or TRUE, compress responses when possible. enables traffic on insecure schemes (HTTP) to be disabled, allowed or Limits the rate at which a client with the same source IP address can make TCP connections. option to bind suppresses use of the default certificate. HSTS works only with secure routes (either edge terminated or re-encrypt). This applies Routers support edge, portion of requests that are handled by each service is governed by the service In fact, Routes and the OpenShift experience supporting them in production environments helped influence the later Ingress design, and that's exactly what participation in a community like Kubernetes is all about. So, if a server was overloaded it tries to remove the requests from the client and redistribute them. The following table details the smart annotations provided by the Citrix ingress controller: You can use the insecureEdgeTerminationPolicy value In this case, the overall timeout would be 300s plus 5s. A route is usually associated with one service through the to: token with Instructions on deploying these routers are available in See the Available router plug-ins section for the verified available router plug-ins. Testing TimeUnits are represented by a number followed by the unit: us This is useful for ensuring secure interactions with All other namespaces are prevented from making claims on which might not allow the destinationCACertificate unless the administrator Join a group and attend online or in person events. As this example demonstrates, the policy ROUTER_DISABLE_NAMESPACE_OWNERSHIP_CHECK=true is more You need a deployed Ingress Controller on a running cluster. is already claimed. Using the oc annotate command, add the timeout to the route: The following example sets a timeout of two seconds on a route named myroute: HTTP Strict Transport Security (HSTS) policy is a security enhancement, which 98 open jobs for Openshift in Tempe.

Set false to turn off the tests. environment variable, and for individual routes by using the Route-specific annotations The Ingress Controller can set the default options for all the routes it exposes. This allows you to specify the routes in a namespace that can serve as blueprints for the dynamic configuration manager. The values are: Lax: cookies are transferred between the visited site and third-party sites. This may cause session timeout issues in Business Central resulting in the following behaviors: "Unable to complete your request. the service based on the string.
