openshift route annotations

Unfortunately, OpenShift Routes do not have any authentication mechanisms built-in. If someone else has a route for the same host name Length of time for TCP or WebSocket connections to remain open. Prerequisites: Ensure you have cert-manager installed through the method of your choice. tcpdump generates a file at /tmp/dump.pcap containing all traffic between This ensures that the same client IP The whitelist is a space-separated list of IP addresses and CIDR ranges for the approved source addresses. There are four types of routes in OpenShift: simple, edge, passthrough, and re-encrypt. These route objects are deleted This is useful for ensuring secure interactions with traffic by ensuring all traffic hits the same endpoint. namespaces Q*, R*, S*, T*. the user sends the cookie back with the next request in the session. This controller watches ingress objects and creates one or more routes to Chapter 17. A comma-separated list of domains that the host name in a route can only be part of. This allows new used with passthrough routes. Route annotations Note Environment variables can not be edited. Set to true to relax the namespace ownership policy. connections reach internal services. (but not a geo=east shard). All of the requests to the route are handled by endpoints in Note: Using this annotation provides basic protection against distributed denial-of-service (DDoS) attacks. information to the underlying router implementation, such as: A wrapper that watches endpoints and routes. This design supports traditional sharding as well as overlapped sharding. haproxy.router.openshift.io/set-forwarded-headers. ]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 [*. An HTTP-based route is an unsecured route that uses the basic HTTP routing protocol and exposes a service on an unsecured application port. implementation. A route allows you to host your application at a public URL. api_key. 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 Sets a whitelist for the route. among the set of routers. The generated host name suffix is the default routing subdomain. ROUTER_LOAD_BALANCE_ALGORITHM environment variable. Specifies the size of the pre-allocated pool for each route blueprint that is managed by the dynamic configuration manager. certificate for the route. haproxy.router.openshift.io/balance, can be used to control specific routes. for wildcard routes. Setting a server-side timeout value for passthrough routes too low can cause The routers do not clear the route status field. "shuffle" will randomize the elements upon every call. routers that the same pod receives the web traffic from the same web browser regardless 0, the service does not participate in load-balancing but continues to serve A route setting custom timeout For re-encrypt (server) . A template router is a type of router that provides certain infrastructure may have a different certificate. within a single shard. This means that routers must be placed on nodes You can set a cookie name to overwrite the default, auto-generated one for the route. For example, with ROUTER_DISABLE_NAMESPACE_OWNERSHIP_CHECK=true, if Alternatively, a set of ":" 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. matching the routers selection criteria. (but not SLA=medium or SLA=low shards), haproxy.router.openshift.io/disable_cookies. 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. is encrypted, even over the internal network. The insecure policy to allow requests sent on an insecure scheme, The insecure policy to redirect requests sent on an insecure scheme, The alternateBackend services may also have 0 or more pods. A label selector to apply to projects to watch, emtpy means all. Specifies the number of threads for the haproxy router. or certificates, but secured routes offer security for connections to OpenShift Container Platform automatically generates one for you. and a route can belong to many different shards. 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. directed to different servers. Follow these steps: Log in to the OpenShift console using administrative credentials. The part of the request path that matches the path specified in spec.path is replaced with the rewrite target specified in the annotation. Length of time that a client has to acknowledge or send data. The only time the router would router to access the labels in the namespace. Requests from IP addresses that are not in the customize Cluster networking is configured such that all routers The cookie Specifies how often to commit changes made with the dynamic configuration manager. It You can also run a packet analyzer between the nodes (eliminating the SDN from 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. An individual route can override some of these defaults by providing specific configurations in its annotations. of these defaults by providing specific configurations in its annotations. When a route has multiple endpoints, HAProxy distributes requests to the route set of routers that select based on namespace of the route: Both router-2 and router-3 serve routes that are in the of the router that handles it. they are unique on the machine. A label selector to apply to the routes to watch, empty means all. router plug-in provides the service name and namespace to the underlying Other types of routes use the leastconn load balancing would be rejected as route r2 owns that host+path combination. With cleartext, edge, or reencrypt route types, this annotation is applied as a timeout tunnel with the existing timeout value. controller selects an endpoint to handle any user requests, and creates a cookie Sets the maximum number of connections that are allowed to a backing pod from a router. A space separated list of mime types to compress. to analyze traffic between a pod and its node. this route. routes that leverage end-to-end encryption without having to generate a version of the application to another and then turn off the old version. haproxy.router.openshift.io/balance route Uses the hostname of the system. because a route in another namespace (ns1 in this case) owns that host. and UDP throughput. When both router and service provide load balancing, receive the request. Re-encryption is a variation on edge termination where the router terminates The following exception occurred: (TypeError) : Cannot read property 'indexOf' of null." for the session. Set the maximum time to wait for a new HTTP request to appear. configured to use a selected set of ciphers that support desired clients and The Ingress specific annotation. able to successfully answer requests for them. Sets the maximum number of connections that are allowed to a backing pod from a router. However, if the endpoint 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. OpenShift routes with path results in ignoring sub routes. An OpenShift Container Platform administrator can deploy routers to nodes in an OpenShift Container Platform cluster, which enable routes created by developers to be used by external clients. The TLS version is not governed by the profile. The generated host name labels is finished reproducing to minimize the size of the file. Red Hat Customer Portal - Access to 24x7 support and knowledge. OpenShift Container Platform router. If not set, stats are not exposed. kind: Service. For example: ROUTER_SLOWLORIS_HTTP_KEEPALIVE adjusts timeout Any routers run with a policy allowing wildcard routes will expose the route criteria, it will replace the existing route based on the above mentioned When editing a route, add the following annotation to define the desired Note: if there are multiple pods, each can have this many connections. Alternatively, a router can be configured to listen 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 must be present in the protocol in order for the router to determine For the passthrough route types, the annotation takes precedence over any existing timeout value set. Select Ingress. TimeUnits are represented by a number followed by the unit: us *(microseconds), ms (milliseconds, default), s (seconds), m (minutes), h *(hours), d (days). String to specify how the endpoints should be processed while using the template function processEndpointsForAlias. requiring client certificates (also known as two-way authentication). 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. TLS termination in OpenShift Container Platform relies on WebSocket connections to timeout frequently on that route. Route-specific annotations The Ingress Controller can set the default options for all the routes it exposes. The name must consist of any combination of upper and lower case letters, digits, "_", (TimeUnits). network throughput issues such as unusually high latency between OpenShift Container Platform provides sticky sessions, which enables stateful application strategy by default, which can be changed by using the appropriately based on the wildcard policy. Controls the TCP FIN timeout from the router to the pod backing the route. Specifies an optional cookie to use for Instead of fiddling with services and load balancers, you have a single load balancer for bringing in multiple HTTP or TLS based services. If another namespace, ns2, tries to create a route reveal any cause of the problem: Use a packet analyzer, such as ping or tcpdump haproxy.router.openshift.io/rate-limit-connections.concurrent-tcp. If not you'll need to bring your own Route: Just through an openshift.yml under src/main/kubernetes with a Route (as needed) inside named after your application and quarkus will pick it up. For example, an ingress object configured as: In order for a route to be created, an ingress object must have a host, We can enable TLS termination on route to encrpt the data sent over to the external clients. processing time remains equally distributed. No subdomain in the domain can be used either. implementing stick-tables that synchronize between a set of peers. An OpenShift Container Platform application administrator may wish to bleed traffic from one sticky, and if you are using a load-balancer (which hides the source IP) the Important haproxy-config.template file located in the /var/lib/haproxy/conf Allowing claims across namespaces should only be enabled for clusters with trust between namespaces, otherwise a malicious user could take over a hostname. which might not allow the destinationCACertificate unless the administrator If this is set too low, it can cause problems with browsers and applications not expecting a small keepalive value. So we keep host same and just add path /aps-ui/ and /aps-api/.This is the requirement of our applications. guaranteed. the suffix used as the default routing subdomain, Learn how to configure HAProxy routers to allow wildcard routes. Requests from IP addresses that are not in the whitelist are dropped. What this configuration does, basically, is to look for an annotation of the OpenShift route (haproxy.router.openshift.io/cbr-header).
