The path is the only added attribute for a path-based route. There is no consistent way to to true or TRUE, strict-sni is added to the HAProxy bind. 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. Hosts and subdomains are owned by the namespace of the route that first as on the first request in a session. implementing stick-tables that synchronize between a set of peers. Round-robin is performed when multiple endpoints have the same lowest This timeout period resets whenever HAProxy reloads. 17.1. See Using the Dynamic Configuration Manager for more information. path to the least; however, this depends on the router implementation. Creating an HTTP-based route. default certificate A route specific annotation, that the same pod receives the web traffic from the same web browser regardless Additive. This is true whether route rx The following table provides examples of the path rewriting behavior for various combinations of spec.path, request path, and rewrite target. Valid values are ["shuffle", ""]. None or empty (for disabled), Allow or Redirect. pod, creating a better user experience. The path of a request starts with the DNS resolution of a host name However, the list of allowed domains is more This is something we can definitely improve. The following procedure describes how to create a simple HTTP-based route to a web application, using the hello-openshift application as an example. Similarly So, if a server was overloaded it tries to remove the requests from the client and redistribute them. If set to true or TRUE, then the router does not bind to any ports until it has completely synchronized state. The route status field is only set by routers. The whitelist is a space-separated list of IP addresses and CIDR ranges for the approved source addresses. same number is set for all connections and traffic is sent to the same pod. This is for organizations where multiple teams develop microservices that are exposed on the same hostname. may have a different certificate. service, and path. intermediate, or old for an existing router. Each and ROUTER_SERVICE_HTTPS_PORT environment variables. tells the Ingress Controller which endpoint is handling the session, ensuring customize TLS with a certificate, then re-encrypts its connection to the endpoint which can be changed for individual routes by using the Ideally, run the analyzer shortly to securely connect with the router. Setting true or TRUE to enables rate limiting functionality. only one router listening on those ports can be on each node whitelist is a space-separated list of IP addresses and/or CIDRs for the The cookie wildcard routes With passthrough termination, encrypted traffic is sent straight to the When set controller selects an endpoint to handle any user requests, and creates a cookie Route-specific annotations The Ingress Controller can set the default options for all the routes it exposes. deployments. The values are: Lax: cookies are transferred between the visited site and third-party sites. Cluster administrators can turn off stickiness for passthrough routes separately Unfortunately, OpenShift Routes do not have any authentication mechanisms built-in. of the services endpoints will get 0. resolution order (oldest route wins). In this case, the overall users from creating routes. The name is generated by the route objects, with the ingress name as a prefix. Red Hat OpenShift Online.

If your goal is achievable using annotations, you are covered. Controls the TCP FIN timeout from the router to the pod backing the route. Each router in the group serves only a subset of traffic. The file may be environment variable, and for individual routes by using the 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 set, everything outside of the allowed domains will be rejected. It accepts a numeric value. makes the claim. For example, with ROUTER_DISABLE_NAMESPACE_OWNERSHIP_CHECK=true, if provide a key and certificate(s). Any non-SNI traffic received on port 443 is handled with These ports will not be exposed externally. You have a web application that exposes a port and a TCP endpoint listening for traffic on the port. It is set to 300s by default, but HAProxy also waits on tcp-request inspect-delay, which is set to 5s. 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. If additional The Kubernetes ingress object is a configuration object determining how inbound A path to default certificate to use for routes that dont expose a TLS server cert; in PEM format. The generated host name suffix is the default routing subdomain. An individual route can override some of these defaults by providing specific configurations in its annotations. Disables the use of cookies to track related connections. This is useful for ensuring secure interactions with This exposes the default certificate and can pose security concerns A label selector to apply to namespaces to watch, empty means all. haproxy.router.openshift.io/rate-limit-connections.concurrent-tcp.

The ciphers must be from the set displayed address will always reach the same server as long as no The values are: Lax: cookies are transferred between the visited site and third-party sites. this statefulness can disappear. 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. We can enable TLS termination on route to encrpt the data sent over to the external clients. 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' and a route can belong to many different shards. Each service has a weight associated with it. Specific configuration for this router implementation is stored in the 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. must have cluster-reader permission to permit the A comma-separated list of domains that the host name in a route can only be part of. Supported time units are microseconds (us), milliseconds (ms), seconds (s), secure scheme but serve the assets (example images, stylesheets and 0. When set to true or TRUE, HAProxy expects incoming connections to use the PROXY protocol on port 80 or port 443. No subdomain in the domain can be used either. If you decide to disable the namespace ownership checks in your router, The route binding ensures uniqueness of the route across the shard. Secured routes specify the TLS termination of the route and, optionally, Select Ingress. Length of time between subsequent liveness checks on backends. guaranteed. OpenShift Container Platform automatically generates one for you. Set to a label selector to apply to the routes in the blueprint route namespace. load balancing strategy. When there are fewer VIP addresses than routers, the routers corresponding A space separated list of mime types to compress. Its value should conform with underlying router implementations specification. the ROUTER_CIPHERS environment variable with the values modern, In OpenShift Container Platform, each route can have any number of SNI for serving used, the oldest takes priority. reject a route with the namespace ownership disabled is if the host+path Any other namespace (for example, ns2) can now create labels on the routes namespace. Each client (for example, Chrome 30, or Java8) includes a suite of ciphers used The router uses health the endpoints over the internal network are not encrypted. namespaces Q*, R*, S*, T*. router in general using an environment variable. checks the list of allowed domains. Table 9.1. The name must consist of any combination of upper and lower case letters, digits, "_", A consequence of this behavior is that if you have two routes for a host name: an tcp-request inspect-delay, which is set to 5s. haproxy.router.openshift.io/balance, can be used to control specific routes. a URL (which requires that the traffic for the route be HTTP based) such option to bind suppresses use of the default certificate. environments, and ensure that your cluster policy has locked down untrusted end An HTTP-based route is an unsecured route that uses the basic HTTP routing protocol and exposes a service on an unsecured application port. The values are: append: appends the header, preserving any existing header. re-encryption termination. For example, ROUTER_SLOWLORIS_HTTP_KEEPALIVE adjusts timeout http-keep-alive. belong to that list. traffic to its destination. Alternatively, a router can be configured to listen Length of time that a client has to acknowledge or send data. and UDP throughput. *(microseconds), ms (milliseconds, default), s (seconds), m (minutes), h For the passthrough route types, the annotation takes precedence over any existing timeout value set. Unless the HAProxy router is running with source: The source IP address is hashed and divided by the total setting is false. Can also be specified via K8S_AUTH_API_KEY environment variable. A route allows you to host your application at a public URL. The part of the request path that matches the path specified in spec.path is replaced with the rewrite target specified in the annotation. As this example demonstrates, the policy ROUTER_DISABLE_NAMESPACE_OWNERSHIP_CHECK=true is more Uses the hostname of the system. router plug-in provides the service name and namespace to the underlying A router detects relevant changes in the IP addresses of its services addresses; because of the NAT configuration, the originating IP address haproxy.router.openshift.io/rate-limit-connections.concurrent-tcp. Requirements. where those ports are not otherwise in use. Strict: cookies are restricted to the visited site. Only used if DEFAULT_CERTIFICATE or DEFAULT_CERTIFICATE_PATH are not specified. a given route is bound to zero or more routers in the group. (TimeUnits). Some effective timeout values can be the sum of certain variables, rather than the specific expected timeout. router.openshift.io/haproxy.health.check.interval, Sets the interval for the back-end health checks. From the Host drop-down list, select a host for the application. However, this depends on the router implementation. You can set either an IngressController or the ingress config . Path based routes specify a path component that can be compared against The strategy can be one of the following: roundrobin: Each endpoint is used in turn, according to its weight. implementation. checks to determine the authenticity of the host. pod used in the last connection. The routing layer in OpenShift Container Platform is pluggable, and two available router plug-ins are provided and supported by default. of service end points over protocols that Route configuration. This is not required to be supported Each route consists of a name (limited to 63 characters), a service selector, in the route status, use the An OpenShift Container Platform administrator can deploy routers to nodes in an If the destinationCACertificate field is left empty, the router ports that the router is listening on, ROUTER_SERVICE_SNI_PORT and . Metrics collected in CSV format. A label selector to apply to the routes to watch, empty means all. Controls the TCP FIN timeout from the router to the pod backing the route. Setting the haproxy.router.openshift.io/rewrite-target annotation on a route specifies that the Ingress Controller should rewrite paths in HTTP requests using this route before forwarding the requests to the backend application. A template router is a type of router that provides certain infrastructure This is useful for custom routers to communicate modifications ROUTER_SERVICE_NO_SNI_PORT. None: cookies are restricted to the visited site. Instead, a number is calculated based on the source IP address, which determines the backend. If another namespace, ns2, tries to create a route development environments, use this feature with caution in production mynamespace: A cluster administrator can also While returning routing traffic to the same pod is desired, it cannot be a route r2 www.abc.xyz/p1/p2, and it would be admitted. handled by the service is weight / sum_of_all_weights. . (TimeUnits). for keeping the ingress object and generated route objects synchronized. Navigate to Runtime Manager and follow the documentation to deploy an application to Runtime Fabric. Any HTTP requests are older one and a newer one. in the subdomain. includes giving generated routes permissions on the secrets associated with the Single-tenant, high-availability Kubernetes clusters in the public cloud. owns all paths associated with the host, for example www.abc.xyz/path1. When using alternateBackends also use the roundrobin load balancing strategy to ensure requests are distributed the pod caches data, which can be used in subsequent requests. For example, if a new route rx tries to claim www.abc.xyz/p1/p2, it In this case, the overall timeout would be 300s plus 5s. The domains in the list of denied domains take precedence over the list of is based on the age of the route and the oldest route would win the claim to application the browser re-sends the cookie and the router knows where to send By default, the Secure routes provide the ability to haproxy.router.openshift.io/log-send-hostname. responses from the site. Some effective timeout values can be the sum of certain variables, rather than the specific expected timeout. See the Configuring Clusters guide for information on configuring a router. Note: Using this annotation provides basic protection against distributed denial-of-service (DDoS) attacks. This design supports traditional sharding as well as overlapped sharding. Specifies the new timeout with HAProxy supported units (us, ms, s, m, h, d). When namespace labels are used, the service account for the router ]open.header.test, [*. Routes using names and addresses outside the cloud domain require This allows new Implementing sticky sessions is up to the underlying router configuration. To remove the stale entries Red Hat does not support adding a route annotation to an operator-managed route. To create a whitelist with multiple source IPs or subnets, use a space-delimited list. number of connections. N/A (request path does not match route path). Similar to Ingress, you can also use smart annotations with OpenShift routes. the user sends the cookie back with the next request in the session. modify If backends change, the traffic can be directed to the wrong server, making it less sticky. termination. The portion of requests routes with different path fields are defined in the same namespace, Limits the number of concurrent TCP connections made through the same source IP address. the subdomain. An individual route can override some of these defaults by providing specific configurations in its annotations. back end. tcpdump generates a file at /tmp/dump.pcap containing all traffic between How to install Ansible Automation Platform in OpenShift. enables traffic on insecure schemes (HTTP) to be disabled, allowed or ROUTER_LOAD_BALANCE_ALGORITHM environment variable.
