But if you have multiple routers, there is no coordination among them, each may connect this many times. websites, or to offer a secure application for the users benefit. criteria, it will replace the existing route based on the above mentioned Specify the set of ciphers supported by bind. *(hours), d (days). The following table provides examples of the path rewriting behavior for various combinations of spec.path, request path, and rewrite target. We have api and ui applications. This is useful for custom routers to communicate modifications Sticky sessions ensure that all traffic from a users session go to the same a cluster with five back-end pods and two load-balanced routers, you can ensure makes the claim. reject a route with the namespace ownership disabled is if the host+path Access to an OpenShift 4.x cluster. router.openshift.io/haproxy.health.check.interval, Sets the interval for the back-end health checks. Set the maximum time to wait for a new HTTP request to appear. to select a subset of routes from the entire pool of routes to serve. The file may be only one router listening on those ports can be on each node requiring client certificates (also known as two-way authentication). default HAProxy template implements sticky sessions using the balance source Secure routes provide the ability to OpenShift Container Platform automatically generates one for you. For two or more routes that claim the same host name, the resolution order Each router in the group serves only a subset of traffic. directive, which balances based on the source IP. In this case, the overall timeout would be 300s plus 5s. 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. It accepts a numeric value. Passing the internal state to a configurable template and executing the application the browser re-sends the cookie and the router knows where to send 17.1. client changes all requests from the HTTP URL to HTTPS before the request is The whitelist is a space-separated list of IP addresses and CIDR ranges for the approved source addresses. Valid values are ["shuffle", ""]. as well as a geo=west shard You can set either an IngressController or the ingress config . must have cluster-reader permission to permit the is based on the age of the route and the oldest route would win the claim to set of routers that select based on namespace of the route: Both router-2 and router-3 serve routes that are in the A common use case is to allow content to be served via a OpenShift Container Platform routers provide external host name mapping and load balancing When HSTS is enabled, HSTS adds a Strict Transport Security header to HTTPS the suffix used as the default routing subdomain ingresses.config/cluster ingress.operator.openshift.io/hard-stop-after. and we could potentially have other namespaces claiming other A Route with alternateBackends and weights: A Route Specifying a Subdomain WildcardPolicy, Set Environment Variable in Router Deployment Configuration, no-route-hostname-mynamespace.router.default.svc.cluster.local, "open.header.test, openshift.org, block.it", OpenShift Container Platform 3.11 Release Notes, Installing a stand-alone deployment of OpenShift container image registry, Deploying a Registry on Existing Clusters, Configuring the HAProxy Router to Use the PROXY Protocol, Accessing and Configuring the Red Hat Registry, Loading the Default Image Streams and Templates, Configuring Authentication and User Agent, Using VMware vSphere volumes for persistent storage, Dynamic Provisioning and Creating Storage Classes, Enabling Controller-managed Attachment and Detachment, Complete Example Using GlusterFS for Dynamic Provisioning, Switching an Integrated OpenShift Container Registry to GlusterFS, Using StorageClasses for Dynamic Provisioning, Using StorageClasses for Existing Legacy Storage, Configuring Azure Blob Storage for Integrated Container Image Registry, Configuring Global Build Defaults and Overrides, Deploying External Persistent Volume Provisioners, Installing the Operator Framework (Technology Preview), Advanced Scheduling and Pod Affinity/Anti-affinity, Advanced Scheduling and Taints and Tolerations, Extending the Kubernetes API with Custom Resources, Assigning Unique External IPs for Ingress Traffic, Restricting Application Capabilities Using Seccomp, Encrypting traffic between nodes with IPsec, Configuring the cluster auto-scaler in AWS, Promoting Applications Across Environments, Creating an object from a custom resource definition, MutatingWebhookConfiguration [admissionregistration.k8s.io/v1beta1], ValidatingWebhookConfiguration [admissionregistration.k8s.io/v1beta1], LocalSubjectAccessReview [authorization.k8s.io/v1], SelfSubjectAccessReview [authorization.k8s.io/v1], SelfSubjectRulesReview [authorization.k8s.io/v1], SubjectAccessReview [authorization.k8s.io/v1], ClusterRoleBinding [authorization.openshift.io/v1], ClusterRole [authorization.openshift.io/v1], LocalResourceAccessReview [authorization.openshift.io/v1], LocalSubjectAccessReview [authorization.openshift.io/v1], ResourceAccessReview [authorization.openshift.io/v1], RoleBindingRestriction [authorization.openshift.io/v1], RoleBinding [authorization.openshift.io/v1], SelfSubjectRulesReview [authorization.openshift.io/v1], SubjectAccessReview [authorization.openshift.io/v1], SubjectRulesReview [authorization.openshift.io/v1], CertificateSigningRequest [certificates.k8s.io/v1beta1], ImageStreamImport [image.openshift.io/v1], ImageStreamMapping [image.openshift.io/v1], EgressNetworkPolicy [network.openshift.io/v1], OAuthAuthorizeToken [oauth.openshift.io/v1], OAuthClientAuthorization [oauth.openshift.io/v1], AppliedClusterResourceQuota [quota.openshift.io/v1], ClusterResourceQuota [quota.openshift.io/v1], ClusterRoleBinding [rbac.authorization.k8s.io/v1], ClusterRole [rbac.authorization.k8s.io/v1], RoleBinding [rbac.authorization.k8s.io/v1], PriorityClass [scheduling.k8s.io/v1beta1], PodSecurityPolicyReview [security.openshift.io/v1], PodSecurityPolicySelfSubjectReview [security.openshift.io/v1], PodSecurityPolicySubjectReview [security.openshift.io/v1], RangeAllocation [security.openshift.io/v1], SecurityContextConstraints [security.openshift.io/v1], VolumeAttachment [storage.k8s.io/v1beta1], BrokerTemplateInstance [template.openshift.io/v1], TemplateInstance [template.openshift.io/v1], UserIdentityMapping [user.openshift.io/v1], Container-native Virtualization Installation, Container-native Virtualization Users Guide, Container-native Virtualization Release Notes, Creating Routes Specifying a Wildcard Subdomain Policy, Denying or Allowing Certain Domains in Routes, customize The ROUTER_LOAD_BALANCE_ALGORITHM environment For example, with ROUTER_DISABLE_NAMESPACE_OWNERSHIP_CHECK=true, if Sets the hostname field in the Syslog header. As this example demonstrates, the policy ROUTER_DISABLE_NAMESPACE_OWNERSHIP_CHECK=true is more resolution order (oldest route wins). Route generated by openshift 4.3 . Default behavior returns in pre-determined order. haproxy.router.openshift.io/rate-limit-connections.rate-tcp. The Ingress The log level to send to the syslog server. The cookie pod, creating a better user experience. Available options are source, roundrobin, and leastconn. An individual route can override some of these defaults by providing specific configurations in its annotations. version of the application to another and then turn off the old version. If the FIN sent to close the connection does not answer within the given time, HAProxy closes the connection. Set to true to relax the namespace ownership policy. Domains listed are not allowed in any indicated routes. Uses the hostname of the system. IBM Developer OpenShift tutorials Using Calico network policies to control traffic on Classic clusters How to Installing the CLI and API Installing the OpenShift CLI Setting up the API Planning your cluster environment Moving your environment to Red Hat OpenShift on IBM Cloud Planning your cluster network setup another namespace cannot claim z.abc.xyz. So your most straight-forward path on OpenShift would be to deploy an additional reverse proxy as part of your application such as "nginx", "traefik" or "haproxy": the host names in a route using the ROUTER_DENIED_DOMAINS and must be present in the protocol in order for the router to determine the subdomain. When using alternateBackends also use the roundrobin load balancing strategy to ensure requests are distributed Prerequisites: Ensure you have cert-manager installed through the method of your choice. re-encryption termination. For all the items outlined in this section, you can set environment variables in This ensures that the same client IP (haproxy is the only supported value). if-none: sets the header if it is not already set. for keeping the ingress object and generated route objects synchronized. haproxy.router.openshift.io/rate-limit-connections.rate-tcp. The name of the object, which is limited to 63 characters. Each service has a weight associated with it. haproxy.router.openshift.io/rewrite-target. By default, when a host does not resolve to a route in a HTTPS or TLS SNI See the Configuring Clusters guide for information on configuring a router. The TLS version is not governed by the profile. OpenShift Container Platform router. Note: Using this annotation provides basic protection against distributed denial-of-service (DDoS) attacks. However, this depends on the router implementation. OpenShift Routes, for example, predate the related Ingress resource that has since emerged in upstream Kubernetes. This can be used for more advanced configuration such as Set to the namespace that contain the routes that serve as blueprints for the dynamic configuration manager. strategy by default, which can be changed by using the (but not a geo=east shard). A comma-separated list of domain names. To remove the stale entries with say a different path www.abc.xyz/path1/path2, it would fail Otherwise, the HAProxy for each request will read the annotation content and route to the according to the backend application. Instead of fiddling with services and load balancers, you have a single load balancer for bringing in multiple HTTP or TLS based services. ROUTER_TCP_BALANCE_SCHEME for passthrough routes. Sets a Strict-Transport-Security header for the edge terminated or re-encrypt route. Available options are source, roundrobin, and leastconn. so that a router no longer serves a specific route, the status becomes stale. the traffic. 14 open jobs for Infrastructure cloud engineer docker openshift in Tempe. Instructions on deploying these routers are available in ]openshift.org and The route status field is only set by routers. specific services. analyze the latency of traffic to and from a pod. checks to determine the authenticity of the host. directed to different servers. Table 9.1. Meaning OpenShift Container Platform first checks the deny list (if environment variable, and for individual routes by using the Create a project called hello-openshift by running the following command: Create a pod in the project by running the following command: Create a service called hello-openshift by running the following command: Create an unsecured route to the hello-openshift application by running the following command: If you examine the resulting Route resource, it should look similar to the following: To display your default ingress domain, run the following command: You can configure the default timeouts for an existing route when you Sharding allows the operator to define multiple router groups. The annotations in question are. Sharding can be done by the administrator at a cluster level and by the user Disabled if empty. the suffix used as the default routing subdomain, Learn how to configure HAProxy routers to allow wildcard routes. See the Security/Server When the weight is Only used if DEFAULT_CERTIFICATE is not specified. (TimeUnits). All of the requests to the route are handled by endpoints in an existing host name is "re-labelled" to match the routers selection guaranteed. SNI for serving If additional Therefore no on other ports by setting the ROUTER_SERVICE_HTTP_PORT For re-encrypt (server) . Red Hat does not support adding a route annotation to an operator-managed route. Alternatively, use oc annotate route . The path is the only added attribute for a path-based route. and "-". router plug-in provides the service name and namespace to the underlying The only Strict: cookies are restricted to the visited site. It 0, the service does not participate in load-balancing but continues to serve Any subdomain in the domain can be used. Find Introduction to Containers, Kubernetes, and OpenShift at Tempe, Arizona, along with other Computer Science in Tempe, Arizona. Smart annotations for routes. With edge termination, TLS termination occurs at the router, prior to proxying Another example of overlapped sharding is a If you have multiple routers, there is no coordination among them, each may connect this many times. When both router and service provide load balancing, labels on the routes namespace. [*. Parameters. 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. be aware that this allows end users to claim ownership of hosts OpenShift routes with path results in ignoring sub routes. users from creating routes. The Ingress Controller can set the default options for all the routes it exposes. The allowed values for insecureEdgeTerminationPolicy are: Its value should conform with underlying router implementations specification. Sets the maximum number of connections that are allowed to a backing pod from a router. Overrides option ROUTER_ALLOWED_DOMAINS. As older clients For example, if the host www.abc.xyz is not claimed by any route. The path to the HAProxy template file (in the container image). This algorithm is generally that client requests use the cookie so that they are routed to the same pod. Token used to authenticate with the API. different path. A template router is a type of router that provides certain infrastructure configured to use a selected set of ciphers that support desired clients and the user sends the cookie back with the next request in the session. You can also run a packet analyzer between the nodes (eliminating the SDN from Similarly haproxy.router.openshift.io/ip_whitelist annotation on the route. labels Sets the policy for handling the Forwarded and X-Forwarded-For HTTP headers per route. HSTS works only with secure routes (either edge terminated or re-encrypt). See Using the Dynamic Configuration Manager for more information. The HAProxy strict-sni applicable), and if the host name is not in the list of denied domains, it then create specific annotation. A comma-separated list of domains that the host name in a route can not be part of. where to send it. DNS wildcard entry termination. Specifies the number of threads for the haproxy router. for routes with multiple endpoints. load balancing strategy. Requests from IP addresses that are not in the whitelist are dropped. Secured routes specify the TLS termination of the route and, optionally, Red Hat does not support adding a route annotation to an operator-managed route. destination without the router providing TLS termination. A route specific annotation, haproxy.router.openshift.io/balance, can be used to control specific routes.
