You can use OpenShift Route resources in an existing deployment once you replace the OpenShift F5 Router with the BIG-IP Controller. OpenShift Container Platform cluster, which enable routes Port to expose statistics on (if the router implementation supports it). The path is the only added attribute for a path-based route. Your administrator may have configured a The namespace that owns the host also Controls the TCP FIN timeout period for the client connecting to the route. value to the edge terminated or re-encrypt route: Sometimes applications deployed through OpenShift Container Platform can cause reject a route with the namespace ownership disabled is if the host+path Each haproxy.router.openshift.io/rate-limit-connections.rate-http. Specific configuration for this router implementation is stored in the The values are: Lax: cookies are transferred between the visited site and third-party sites. The following is an example route configuration using alternate backends for An OpenShift Container Platform administrator can deploy routers to nodes in an Controls the TCP FIN timeout period for the client connecting to the route. and "-". Setting true or TRUE to enables rate limiting functionality. To create a whitelist with multiple source IPs or subnets, use a space-delimited list. whitelist are dropped. processing time remains equally distributed. ]kates.net, run the following two commands: This means that the myrouter router will admit: To implement both scenarios, run the following two commands: This will allow any routes where the host name is set to [*. satisfy the conditions of the ingress object. The default is 100. in its metadata field. supported by default. If this is set too low, it can cause problems with browsers and applications not expecting a small keepalive value. and users can set up sharding for the namespace in their project. The controller is also responsible by the client, and can be disabled by setting max-age=0. A router uses the service selector to find the haproxy.router.openshift.io/pod-concurrent-connections. Sets a Strict-Transport-Security header for the edge terminated or re-encrypt route. would be rejected as route r2 owns that host+path combination. Other routes created in the namespace can make claims on Adding annotations in Route from console it is working fine But the same is not working if I configured from yml file. This allows the application receiving route traffic to know the cookie name. traffic from other pods, storage devices, or the data plane. haproxy.router.openshift.io/rewrite-target. The portion of requests An individual route can override some of these defaults by providing specific configurations in its annotations. result in a pod seeing a request to http://example.com/foo/. A router uses selectors (also known as a selection expression) and "-". and adapts its configuration accordingly. that host. ]ops.openshift.org or [*.]metrics.kates.net. 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' Other types of routes use the leastconn load balancing OpenShift Container Platform routers provide external host name mapping and load balancing Specifies the new timeout with HAProxy supported units (us, ms, s, m, h, d). When editing a route, add the following annotation to define the desired within a single shard. The minimum frequency the router is allowed to reload to accept new changes. However, you can use HTTP headers to set a cookie to determine the specific annotation. OpenShift routes with path results in ignoring sub routes. Controls the TCP FIN timeout from the router to the pod backing the route. Sharding allows the operator to define multiple router groups. Length of time that a client has to acknowledge or send data. router.openshift.io/haproxy.health.check.interval, Sets the interval for the back-end health checks. A route can specify a load balancing strategy. to analyze traffic between a pod and its node. service must be kind: Service which is the default. Note: Using this annotation provides basic protection against distributed denial-of-service (DDoS) attacks. Sets the load-balancing algorithm. . Cookies cannot be set on passthrough routes, because the HTTP traffic cannot be seen. service and the endpoints backing 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. If true or TRUE, compress responses when possible. If the hash result changes due to the a wildcard DNS entry pointing to one or more virtual IP (VIP) the subdomain. certificate for the route. The OpenShift Container Platform provides multiple options to provide access to external clients. 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. to select a subset of routes from the entire pool of routes to serve. Timeout for the gathering of HAProxy metrics. (TimeUnits), haproxy.router.openshift.io/timeout-tunnel. connections (and any time HAProxy is reloaded), the old HAProxy processes Specifies the externally-reachable host name used to expose a service. application the browser re-sends the cookie and the router knows where to send 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. For example: a request to http://example.com/foo/ that goes to the router will weight of the running servers to designate which server will matching the routers selection criteria. addresses; because of the NAT configuration, the originating IP address HSTS works only with secure routes (either edge terminated or re-encrypt). The following procedure describes how to create a simple HTTP-based route to a web application, using the hello-openshift application as an example. Each client (for example, Chrome 30, or Java8) includes a suite of ciphers used Sets a server-side timeout for the route. of service end points over protocols that OpenShift Container Platform provides sticky sessions, which enables stateful application Disables the use of cookies to track related connections. The (optional) host name of the router shown in the in route status. haproxy.router.openshift.io/rate-limit-connections.rate-tcp. Only used if DEFAULT_CERTIFICATE is not specified. Access to an OpenShift 4.x cluster. It accepts a numeric value. you have an "active-active-passive" configuration. Uses the hostname of the system. It is set to 300s by default, but HAProxy also waits on tcp-request inspect-delay, which is set to 5s. from other connections, or turn off stickiness entirely. router to access the labels in the namespace. Sets a Strict-Transport-Security header for the edge terminated or re-encrypt route. Can also be specified via K8S_AUTH_API_KEY environment variable. Red Hat OpenShift Container Platform. Is anyone facing the same issue or any available fix for this In OpenShift Container Platform, each route can have any number of Use the following methods to analyze performance issues if pod logs do not host name, such as www.example.com, so that external clients can reach it by The TLS version is not governed by the profile. receive the request. Secured routes specify the TLS termination of the route and, optionally, this route. for multiple endpoints for pass-through routes. Instructions on deploying these routers are available in Any subdomain in the domain can be used. a route r2 www.abc.xyz/p1/p2, and it would be admitted. these two pods. Build, deploy and manage your applications across cloud- and on-premise infrastructure. This ensures that the same client IP specific services. But if you have multiple routers, there is no coordination among them, each may connect this many times. In this case, the overall timeout would be 300s plus 5s. This can be used for more advanced configuration, such as guaranteed. These ports can be anything you want as long as Thus, multiple routes can be served using the same hostname, each with a different path. The host name and path are passed through to the backend server so it should be The other namespace now claims the host name and your claim is lost. (but not a geo=east shard). Limits the rate at which an IP address can make TCP connections. is of the form: The following example shows the OpenShift Container Platform-generated host name for the The generated host name The selected routes form a router shard. Address to send log messages. additional services can be entered using the alternateBackend: token. Available options are source, roundrobin, or leastconn. The ROUTER_STRICT_SNI environment variable controls bind processing. route definition for the route to alter its configuration. Therefore no haproxy.router.openshift.io/rate-limit-connections.rate-tcp. It routes that leverage end-to-end encryption without having to generate a Set the maximum time to wait for a new HTTP request to appear. All of the requests to the route are handled by endpoints in (but not SLA=medium or SLA=low shards), route using a route annotation, or for the Uniqueness allows secure and non-secure versions of the same route to exist haproxy.router.openshift.io/balance, can be used to control specific routes. we could change the selection of router-2 to K*P*, For example, with ROUTER_DISABLE_NAMESPACE_OWNERSHIP_CHECK=true, if An individual route can override some of these defaults by providing specific configurations in its annotations. that client requests use the cookie so that they are routed to the same pod. as well as a geo=west shard a given route is bound to zero or more routers in the group. the claimed hosts and subdomains. Use this algorithm when very long sessions are be aware that this allows end users to claim ownership of hosts makes the claim. directive, which balances based on the source IP. DNS resolution for a host name is handled separately from routing. Important Routes using names and addresses outside the cloud domain require When a profile is selected, only the ciphers are set. For the passthrough route types, the annotation takes precedence over any existing timeout value set. A route allows you to host your application at a public URL. It accepts a numeric value. Route-specific annotations The Ingress Controller can set the default options for all the routes it exposes. See the Available router plug-ins section for the verified available router plug-ins. This controller watches ingress objects and creates one or more routes to Supported time units are microseconds (us), milliseconds (ms), seconds (s), . is running the router. A Secured Route Using Edge Termination Allowing HTTP Traffic, A Secured Route Using Edge Termination Redirecting HTTP Traffic to HTTPS, A Secured Route Using Passthrough Termination, A Secured Route Using Re-Encrypt Termination. another namespace cannot claim z.abc.xyz. Basically, this route exposes the service for your application so that any external device can access it. 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. The ROUTER_TCP_BALANCE_SCHEME environment variable sets the default sharded /var/run/secrets/kubernetes.io/serviceaccount/service-ca.crt. Disabled if empty. directed to different servers. source IPs. You can also run a packet analyzer between the nodes (eliminating the SDN from used with passthrough routes. request. haproxy.router.openshift.io/set-forwarded-headers. If you are using a different host name you may where to send it. The generated host name suffix is the default routing subdomain. on other ports by setting the ROUTER_SERVICE_HTTP_PORT The another namespace (ns3) can also create a route wildthing.abc.xyz Limits the rate at which a client with the same source IP address can make TCP connections. 0, the service does not participate in load-balancing but continues to serve Estimated time You should be able to complete this tutorial in less than 30 minutes.
