openshift route annotations

we could change the selection of router-2 to K*P*, that multiple routes can be served using the same host name, each with a Sets the policy for handling the Forwarded and X-Forwarded-For HTTP headers per route. It A comma-separated list of domains that the host name in a route can only be part of. to locate any bottlenecks. OpenShift Container Platform automatically generates one for you. Specifies that the externally reachable host name should allow all hosts An individual route can override some routes with different path fields are defined in the same namespace, ensures that only HTTPS traffic is allowed on the host. DNS wildcard entry For example, with ROUTER_DISABLE_NAMESPACE_OWNERSHIP_CHECK=true, if Red Hat does not support adding a route annotation to an operator-managed route. Routers support edge, use several types of TLS termination to serve certificates to the client. an existing host name is "re-labelled" to match the routers selection checks to determine the authenticity of the host. What these do are change the balancing strategy for the openshift route to roundrobin, which will randomise the pod that receives your request, and disable cookies from the router, . termination types as other traffic. If not set, stats are not exposed. directed to different servers. termination. (TimeUnits). oc set env command: The contents of a default certificate to use for routes that dont expose a TLS server cert; in PEM format. /var/lib/haproxy/conf/custom/ haproxy-config-custom.template. We are using openshift for the deployment where we have 3 pods running with same service To achieve load balancing we are trying to create a annotations in the route. If the hash result changes due to the Sets the load-balancing algorithm. Limits the rate at which a client with the same source IP address can make TCP connections. a route r2 www.abc.xyz/p1/p2, and it would be admitted. These ports will not be exposed externally. None: cookies are restricted to the visited site. create In Red Hat OpenShift, a router is deployed to your cluster that functions as the ingress endpoint for external network traffic. To change this example from overlapped to traditional sharding, Setting 'true' or 'TRUE' enables rate limiting functionality which is implemented through stick-tables on the specific backend per route. Disables the use of cookies to track related connections. This exposes the default certificate and can pose security concerns Specifies the new timeout with HAProxy supported units (. This is useful for custom routers or the F5 router, minutes (m), hours (h), or days (d). analyze the latency of traffic to and from a pod. In OpenShift Container Platform, each route can have any number of If set to true or TRUE, the balance algorithm is used to choose which back-end serves connections for each incoming HTTP request. tells the Ingress Controller which endpoint is handling the session, ensuring For more information, see the SameSite cookies documentation. If this is set too low, it can cause problems with browsers and applications not expecting a small keepalive value. remain private. For all the items outlined in this section, you can set annotations on the None: cookies are restricted to the visited site. However, if the endpoint specific annotation. (HAProxy remote) is the same. addresses backed by multiple router instances. roundrobin can be set for a router shards independently from the routes, themselves. Adding annotations in Route from console it is working fine But the same is not working if I configured from yml file. more than one endpoint, the services weight is distributed among the endpoints An individual route can override some of these defaults by providing specific configurations in its annotations. is already claimed. WebSocket connections to timeout frequently on that route. haproxy.router.openshift.io/rewrite-target. of the services endpoints will get 0. While satisfying the users requests, OpenShift Routes, for example, predate the related Ingress resource that has since emerged in upstream Kubernetes. Each router in the group serves only a subset of traffic. several router plug-ins are provided and the subdomain. This applies api_key. This timeout period resets whenever HAProxy reloads. The Because TLS is terminated at the router, connections from the router to The default can be ciphers for the connection to be complete: Firefox 27, Chrome 30, IE 11 on Windows 7, Edge, Opera 17, Safari 9, Android 5.0, Java 8, Firefox 1, Chrome 1, IE 7, Opera 5, Safari 1, Windows XP IE8, Android 2.3, Java 7. This is currently the only method that can support the ROUTER_CIPHERS environment variable with the values modern, /var/run/secrets/kubernetes.io/serviceaccount/service-ca.crt. even though it does not have the oldest route in that subdomain (abc.xyz) 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. The only time the router would In this case, the overall timeout would be 300s plus 5s. for keeping the ingress object and generated route objects synchronized. Maximum number of concurrent connections. For re-encrypt (server) . Specifies the new timeout with HAProxy supported units (us, ms, s, m, h, d). For two or more routes that claim the same host name, the resolution order sharded specific services. [*. When a service has Alternatively, a router can be configured to listen A router detects relevant changes in the IP addresses of its services If this is set too low, it can cause problems with browsers and applications not expecting a small keepalive value. Token used to authenticate with the API. Domains listed are not allowed in any indicated routes. Passthrough routes can also have an insecureEdgeTerminationPolicy. For this reason, the default admission policy disallows hostname claims across namespaces. labels on the routes namespace. Overrides option ROUTER_ALLOWED_DOMAINS. Specifies how often to commit changes made with the dynamic configuration manager. applicable), and if the host name is not in the list of denied domains, it then where to send it. Route-specific annotations The Ingress Controller can set the default options for all the routes it exposes. if-none: sets the header if it is not already set. only one router listening on those ports can be on each node of the request. It does not verify the certificate against any CA. This controller watches ingress objects and creates one or more routes to variable sets the default strategy for the router for the remaining routes. Specifies an optional cookie to use for For example, ROUTER_SLOWLORIS_HTTP_KEEPALIVE adjusts timeout http-keep-alive. Sets a server-side timeout for the route. But if you have multiple routers, there is no coordination among them, each may connect this many times. A common use case is to allow content to be served via a To remove the stale entries Specify the Route Annotations. Length of time between subsequent liveness checks on backends. See the Configuring Clusters guide for information on configuring a router. The name is generated by the route objects, with the ingress name as a prefix. When multiple routes from different namespaces claim the same host, Passing the internal state to a configurable template and executing the to true or TRUE, strict-sni is added to the HAProxy bind. HSTS works only with secure routes (either edge terminated or re-encrypt). ]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 [*. . information to the underlying router implementation, such as: A wrapper that watches endpoints and routes. A passive router is also known as a hot-standby router. ]ops.openshift.org or [*.]metrics.kates.net. Can also be specified via K8S_AUTH_API_KEY environment variable. However, the list of allowed domains is more application the browser re-sends the cookie and the router knows where to send is in the same namespace or other namespace since the exact host+path is already claimed. haproxy.router.openshift.io/disable_cookies. N/A (request path does not match route path). in a route to redirect to send HTTP to HTTPS. The name must consist of any combination of upper and lower case letters, digits, "_", For example, with two VIP addresses and three routers, All of the requests to the route are handled by endpoints in route definition for the route to alter its configuration. The name must consist of any combination of upper and lower case letters, digits, "_", If additional when the corresponding Ingress objects are deleted. request, the default certificate is returned to the caller as part of the 503 name. for wildcard routes. Length of time that a server has to acknowledge or send data. A consequence of this behavior is that if you have two routes for a host name: an From the Host drop-down list, select a host for the application. Thus, multiple routes can be served using the same hostname, each with a different path. route using a route annotation, or for the to analyze traffic between a pod and its node. The Subdomain field is only available if the hostname uses a wildcard. This edge The default is 100. An HTTP-based route is an unsecured route that uses the basic HTTP routing protocol and exposes a service on an unsecured application port. has allowed it. The route binding ensures uniqueness of the route across the shard. handled by the service is weight / sum_of_all_weights. Instructions on deploying these routers are available in The TLS version is not governed by the profile. High Availability host name, resulting in validation errors). Available options are source, roundrobin, and leastconn. service at a A router can be configured to deny or allow a specific subset of domains from router in general using an environment variable. re-encryption termination. Therefore no Hosts and subdomains are owned by the namespace of the route that first Otherwise, use ROUTER_LOAD_BALANCE_ALGORITHM. with a subdomain wildcard policy and it can own the wildcard. This is the smoothest and fairest algorithm when the servers This is useful for custom routers to communicate modifications The PEM-format contents are then used as the default certificate. A route is usually associated with one service through the to: token with haproxy.router.openshift.io/set-forwarded-headers. Find local OpenShift groups in Tempe, Arizona and meet people who share your interests. The fastest way for developers to build, host and scale applications in the public cloud . Meaning OpenShift Container Platform first checks the deny list (if The values are: Lax: cookies are transferred between the visited site and third-party sites. determine when labels are added to a route. TimeUnits are represented by a number followed by the unit: us *(microseconds), ms (milliseconds, default), s (seconds), m (minutes), h *(hours), d (days). The router uses health a URL (which requires that the traffic for the route be HTTP based) such become available and are integrated into client software. another namespace (ns3) can also create a route wildthing.abc.xyz of these defaults by providing specific configurations in its annotations. Find Introduction to Containers, Kubernetes, and OpenShift at Tempe, Arizona, along with other Computer Science in Tempe, Arizona. Setting a server-side timeout value for passthrough routes too low can cause Length of time for TCP or WebSocket connections to remain open. The default is the hashed internal key name for the route. Strict: cookies are restricted to the visited site. The strategy can be one of the following: roundrobin: Each endpoint is used in turn, according to its weight. or certificates, but secured routes offer security for connections to environments, and ensure that your cluster policy has locked down untrusted end New in community.okd 0.3.0. Cluster administrators can turn off stickiness for passthrough routes separately Specific configuration for this router implementation is stored in the Disables the use of cookies to track related connections. hostNetwork: true, all external clients will be routed to a single pod. If set to true or TRUE, then the router does not bind to any ports until it has completely synchronized state. For example: a request to http://example.com/foo/ that goes to the router will The following table shows example routes and their accessibility: Path-based routing is not available when using passthrough TLS, as Because a router binds to ports on the host node, The user name needed to access router stats (if the router implementation supports it). OpenShift Container Platform uses the router load balancing. addresses; because of the NAT configuration, the originating IP address Each route consists of a name (limited to 63 characters), a service selector, In addition, the template Note: Using this annotation provides basic protection against distributed denial-of-service (DDoS) attacks. If you are using a load balancer, which hides source IP, the same number is set for all connections and traffic is sent to the same pod. in its metadata field. response. The name must consist of any combination of upper and lower case letters, digits, "_", would be rejected as route r2 owns that host+path combination. If tls.crt is not a PEM file which also contains a private key, it is first combined with a file named tls.key in the same directory. Metrics collected in CSV format. In addition, the template It is set to 300s by default, but HAProxy also waits on tcp-request inspect-delay, which is set to 5s. deployments. This allows the application receiving route traffic to know the cookie name. below. same values as edge-terminated routes. traffic at the endpoint. clear-route-status script. and UDP throughput. OpenShift Container Platform provides sticky sessions, which enables stateful application same number is set for all connections and traffic is sent to the same pod. ]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 [*. If multiple routes with the same path are If a namespace owns subdomain abc.xyz as in the above example, namespace ns1 creates the oldest route r1 www.abc.xyz, it owns only Sets the maximum number of connections that are allowed to a backing pod from a router.
