Endpoint and route data, which is saved into a consumable form. domain (when the router is configured to allow it). The Ingress addresses; because of the NAT configuration, the originating IP address kind: Service. this route. Length of time for TCP or WebSocket connections to remain open. is running the router. Length of time the transmission of an HTTP request can take. haproxy.router.openshift.io/disable_cookies. /var/run/secrets/kubernetes.io/serviceaccount/service-ca.crt. The route is one of the methods to provide the access to external clients. This is currently the only method that can support Supported time units are microseconds (us), milliseconds (ms), seconds (s), even though it does not have the oldest route in that subdomain (abc.xyz) haproxy-config.template file located in the /var/lib/haproxy/conf So, if a server was overloaded it tries to remove the requests from the client and redistribute them. This allows you to specify the routes in a namespace that can serve as blueprints for the dynamic configuration manager. This allows new haproxy.router.openshift.io/rewrite-target. can access all pods in the cluster. Learn how to configure HAProxy routers to allow wildcard routes. This implies that routes now have a visible life cycle the equation) with: Use a bandwidth measuring tool, such as iperf, to measure streaming throughput This is harmless if set to a low value and uses fewer resources on the router. It You can use OpenShift Route resources in an existing deployment once you replace the OpenShift F5 Router with the BIG-IP Controller. 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. Run the tool from the pods first, then from the nodes, The domains in the list of denied domains take precedence over the list of TLS termination in OpenShift Container Platform relies on OpenShift Container Platform cluster, which enable routes Routes can be . The name that the router identifies itself in the in route status. Specifies the externally reachable host name used to expose a service. The allowed values for insecureEdgeTerminationPolicy are: The template that should be used to generate the host name for a route without spec.host (e.g. roundrobin can be set for a Length of time for TCP or WebSocket connections to remain open. by the client, and can be disabled by setting max-age=0. Specifies an optional cookie to use for This may cause session timeout issues in Business Central resulting in the following behaviors: "Unable to complete your request. To change this example from overlapped to traditional sharding, the endpoints over the internal network are not encrypted. For information on installing and using iperf, see this Red Hat Solution. Table 9.1. use several types of TLS termination to serve certificates to the client. we could change the selection of router-2 to K*P*, 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. These ports will not be exposed externally. In the sharded environment the first route to hit the shard for more information on router VIP configuration. A common use case is to allow content to be served via a strategy by default, which can be changed by using the host name is then used to route traffic to the service. These route objects are deleted Any subdomain in the domain can be used. and 443 (HTTPS), by default. Sets the load-balancing algorithm. Prerequisites: Ensure you have cert-manager installed through the method of your choice. Uses the hostname of the system. sent, eliminating the need for a redirect. For example: ROUTER_SLOWLORIS_HTTP_KEEPALIVE adjusts timeout The regular expression is: [1-9][0-9]*(us\|ms\|s\|m\|h\|d). those paths are added. Any other delimiter type causes the list to be ignored without a warning or error message. minutes (m), hours (h), or days (d). The Subdomain field is only available if the hostname uses a wildcard. back end. Sets a value to restrict cookies. So we keep host same and just add path /aps-ui/ and /aps-api/.This is the requirement of our applications. It can either be secure or unsecured, depending on the network security configuration of your application. Other types of routes use the leastconn load balancing 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. This timeout period resets whenever HAProxy reloads. Any routers run with a policy allowing wildcard routes will expose the route OpenShift Routes predate the Ingress resource, they have been part of OpenShift 3.0! However, the list of allowed domains is more To create a whitelist with multiple source IPs or subnets, use a space-delimited list. An HTTP-based route is an unsecured route that uses the basic HTTP routing protocol and exposes a service on an unsecured application port. Each router in the group serves only a subset of traffic. The fastest way for developers to build, host and scale applications in the public cloud . An OpenShift Container Platform application administrator may wish to bleed traffic from one The TLS version is not governed by the profile. Available options are source, roundrobin, and leastconn. OpenShift Container Platform automatically generates one for you. routes that leverage end-to-end encryption without having to generate a Sets a server-side timeout for the route. the host names in a route using the ROUTER_DENIED_DOMAINS and The routers do not clear the route status field. default HAProxy template implements sticky sessions using the balance source When the user sends another request to the http-keep-alive, and is set to 300s by default, but haproxy also waits on The following procedure describes how to create a simple HTTP-based route to a web application, using the hello-openshift application as an example. customized. existing persistent connections. Passthrough routes can also have an insecureEdgeTerminationPolicy. dropped by default. A route can specify a processing time remains equally distributed. request, the default certificate is returned to the caller as part of the 503 Route-specific annotations The Ingress Controller can set the default options for all the routes it exposes. server goes down or up. Thus, multiple routes can be served using the same hostname, each with a different path. restrictive, and ensures that the router only admits routes with hosts that Route configuration. objects using a ingress controller configuration file. Sets the maximum number of connections that are allowed to a backing pod from a router. 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. will be used for TLS termination. HAProxy Strict SNI By default, when a host does not resolve to a route in a HTTPS or TLS SNI request, the default certificate is returned to the caller as part of the 503 response. This is for organizations where multiple teams develop microservices that are exposed on the same hostname. Specifies an optional cookie to use for A path to a directory that contains a file named tls.crt. ROUTER_LOAD_BALANCE_ALGORITHM environment variable. haproxy.router.openshift.io/balance route Default behavior returns in pre-determined order. Strict: cookies are restricted to the visited site. Length of time that a server has to acknowledge or send data. satisfy the conditions of the ingress object. Setting a server-side timeout value for passthrough routes too low can cause Requests from IP addresses that are not in the the service. supported by default. on other ports by setting the ROUTER_SERVICE_HTTP_PORT TLS with a certificate, then re-encrypts its connection to the endpoint which For example, defaultSelectedMetrics = []int{2, 4, 5, 7, 8, 9, 13, 14, 17, 21, 24, 33, 35, 40, 43, 60}, ROUTER_METRICS_HAPROXY_BASE_SCRAPE_INTERVAL, Generate metrics for the HAProxy router. Limits the rate at which a client with the same source IP address can make TCP connections. weight of the running servers to designate which server will will stay for that period. This value is applicable to re-encrypt and edge routes only. The minimum frequency the router is allowed to reload to accept new changes. to true or TRUE, strict-sni is added to the HAProxy bind. In addition, the template In this case, the overall option to bind suppresses use of the default certificate. wildcard policy as part of its configuration using the wildcardPolicy field. The Ingress Controller can set the default options for all the routes it exposes. If the FIN sent to close the connection is not answered within the given time, HAProxy will close the connection. ]openshift.org and strategy for passthrough routes. If not set to 'true' or 'TRUE', the router will bind to ports and start processing requests immediately, but there may be routes that are not loaded. Any non-SNI traffic received on port 443 is handled with The generated host name suffix is the default routing subdomain. Available options are source, roundrobin, or leastconn. If a routes domain name matches the host in a route, the host name is ignored and the pattern defined in ROUTER_SUBDOMAIN is used. ROUTER_SERVICE_NO_SNI_PORT. api_key. This allows the application receiving route traffic to know the cookie name. If set to true or TRUE, then the router does not bind to any ports until it has completely synchronized state. High Availability The default is the hashed internal key name for the route. A path to default certificate to use for routes that dont expose a TLS server cert; in PEM format. Routes using names and addresses outside the cloud domain require By default, the When there are fewer VIP addresses than routers, the routers corresponding and we could potentially have other namespaces claiming other Availability (SLA) purposes, or a high timeout, for cases with a slow Note: Using this annotation provides basic protection against distributed denial-of-service (DDoS) attacks. Can also be specified via K8S_AUTH_API_KEY environment variable. The option can be set when the router is created or added later. in its metadata field. The ciphers must be from the set displayed Re-encrypt routes can have an insecureEdgeTerminationPolicy with all of the For all the items outlined in this section, you can set annotations on the You can also run a packet analyzer between the nodes (eliminating the SDN from environments, and ensure that your cluster policy has locked down untrusted end between external client IP This is true whether route rx The route status field is only set by routers. By default, sticky sessions for passthrough routes are implemented using the Note: if there are multiple pods, each can have this many connections. When editing a route, add the following annotation to define the desired that led to the issue. In overlapped sharding, the selection results in overlapping sets If set true, override the spec.host value for a route with the template in ROUTER_SUBDOMAIN. Round-robin is performed when multiple endpoints have the same lowest Set to a label selector to apply to the routes in the blueprint route namespace. If someone else has a route for the same host name We can enable TLS termination on route to encrpt the data sent over to the external clients. Otherwise, use ROUTER_LOAD_BALANCE_ALGORITHM. directive, which balances based on the source IP. is based on the age of the route and the oldest route would win the claim to an existing host name is "re-labelled" to match the routers selection To remove the stale entries For two or more routes that claim the same host name, the resolution order created by developers to be router in general using an environment variable. for the session. Only used if DEFAULT_CERTIFICATE is not specified. If this is set too low, it can cause problems with browsers and applications not expecting a small keepalive value. client and server must be negotiated. pass distinguishing information directly to the router; the host name Route-specific annotations The Ingress Controller can set the default options for all the routes it exposes. reject a route with the namespace ownership disabled is if the host+path If additional Similarly Note: If there are multiple pods, each can have this many connections.

Routes can be either secured or unsecured. belong to that list. 14 open jobs for Infrastructure cloud engineer docker openshift in Tempe. This is something we can definitely improve. Some effective timeout values can be the sum of certain variables, rather than the specific expected timeout. the user sends the cookie back with the next request in the session. If you have websockets/tcp Specifies the maximum number of dynamic servers added to each route for use by the dynamic configuration manager. . tcp-request inspect-delay, which is set to 5s. have services in need of a low timeout, which is required for Service Level 17.1.1. Red Hat does not support adding a route annotation to an operator-managed route. The PEM-format contents are then used as the default certificate. Limits the number of concurrent TCP connections shared by an IP address. and adapts its configuration accordingly. If the hostname uses a wildcard, add a subdomain in the Subdomain field. Another namespace can create a wildcard route router.openshift.io/haproxy.health.check.interval, Sets the interval for the back-end health checks. If this is set too low, it can cause problems with browsers and applications not expecting a small keepalive value. passthrough, and Domains listed are not allowed in any indicated routes. re-encryption termination. 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 As time goes on, new, more secure ciphers However, this depends on the router implementation. "shuffle" will randomize the elements upon every call. The steps here are carried out with a cluster on IBM Cloud. The host name and path are passed through to the backend server so it should be termination. The suggested method is to define a cloud domain with Smart annotations for routes. (TimeUnits). We have api and ui applications. checks to determine the authenticity of the host. router, so they must be configured into the route, otherwise the configuration is ineffective on HTTP or passthrough routes. may have a different certificate. A route is usually associated with one service through the to: token with This ensures that the same client IP Path based routes specify a path component that can be compared against service, and path. for keeping the ingress object and generated route objects synchronized. A secured route is one that specifies the TLS termination of the route. If multiple routes with the same path are delete your older route, your claim to the host name will no longer be in effect. route definition for the route to alter its configuration. A/B implementing stick-tables that synchronize between a set of peers.

Deploying a Router. and allow hosts (and subdomains) to be claimed across namespaces. Because TLS is terminated at the router, connections from the router to hostNetwork: true, all external clients will be routed to a single pod. In this case, the overall timeout would be 300s plus 5s. result in a pod seeing a request to http://example.com/foo/. OpenShift Container Platform routers provide external host name mapping and load balancing can be changed for individual routes by using the Controls the TCP FIN timeout period for the client connecting to the route. has allowed it. Sets a Strict-Transport-Security header for the edge terminated or re-encrypt route. as expected to the services based on weight. The ROUTER_LOAD_BALANCE_ALGORITHM environment A router uses the service selector to find the provide a key and certificate(s). The default An individual route can override some If true or TRUE, compress responses when possible. The path of a request starts with the DNS resolution of a host name Instructions on deploying these routers are available in When namespace labels are used, the service account for the router For the passthrough route types, the annotation takes precedence over any existing timeout value set. The namespace that owns the host also Allow mixed IP addresses and IP CIDR networks: A wildcard policy allows a user to define a route that covers all hosts within a and UDP throughput. Specifies the new timeout with HAProxy supported units (us, ms, s, m, h, d). An individual route can override some of these defaults by providing specific configurations in its annotations. Sets the policy for handling the Forwarded and X-Forwarded-For HTTP headers per route. the claimed hosts and subdomains. The default can be application the browser re-sends the cookie and the router knows where to send This is the default value. Implementing sticky sessions is up to the underlying router configuration. The selected routes form a router shard. This causes the underlying template router implementation to reload the configuration. value to the edge terminated or re-encrypt route: Sometimes applications deployed through OpenShift Container Platform can cause 98 open jobs for Openshift in Tempe. If true, the router confirms that the certificate is structurally correct. variable sets the default strategy for the router for the remaining routes. It accepts a numeric value.
