OpenShift provides multiple methods for communicating with services running on the platform. While this option provides support for the majority of use cases, there are restrictions which limit the usage by certain applications. In this case, OpenShift Container Platform implements a non-cloud version of the LoadBalancer service type and assigns IP addresses to the services. $ oc -n istio-system expose svc/istio-ingressgateway --port=http2 Automatic sidecar injection.

NGINX and NGINX Plus Routers An Ingress can be configured to give services externally-reachable urls, load balance traffic, terminate SSL, offer name based virtual hosting etc. In the case of edge and re-encrypt routes, the router also uploads and configures the TLS certificate and … The OpenShift API server operator uses the domain from the cluster Ingress configuration as the domain used when generating a default host for a Route resource that does not specify an explicit host. OpenShift route exposes a service at a host name, like www.example.com, so that external clients can reach it by name in a mature fashion. The Ingress controller selects an endpoint to handle any user requests, and creates a cookie for the session. After installation is complete, expose an OpenShift route for the ingress gateway.

Fortunately, OpenShift provides several alternate options, such as ingress, for exposing and accessing services … I had used ingress in 3.11 and included tls.hosts section to use default certificate from the default namespace so route created would be secured. The process launches proxies as children and triggers reloads as necessary after new config has been written. The Ingress Operator uses the domain from the cluster Ingress configuration as the domain for the default Ingress Controller. If logical network type of separations can be considered, then there are ways to stretch a single OpenShift deployment across multiple network zones. Traffic routing is controlled by rules defined on the Ingress resource. You must ensure that the IP address pool you assign terminates at one or more nodes in your cluster. When uploading resources that don’t reside in the default or current Project, specify the correct Project using the --namespace (or -n) flag. That will automatically create a new "domain name" that I can use to access my application from e.g. The Red Hat OpenShift ingress controller implementation is designed to watch ingress objects and create one or more routes to fulfill the conditions specified. If this is the case, skip to the next section. This post presented a few technical approaches. The main difference is that routes are implemented by good, old HAproxy that can be replaced by commercial solution based on F5 BIG-IP. As far as I know you can't edit the host in place for an existing route. The template router code (openshift-router) is generic and creates config files on disk based on the state of the cluster. tls: - This setup is not necessary if you are running OpenShift 4.1 or higher. So now in OpenShift we have a Route objects which do almost the same job as Ingress in Kubernetes.
