Summary: Networking

In standard OpenShift Container Platform (OCP) installations, the cluster networking operator relies on default scripts to configure the external bridge, br-ex. While these defaults work for simple setups, production environments frequently demand robust and redundant setups, such as LACP bonding or active-backup configurations that the default scripts cannot guess.

In this article, we explore advanced configurations for the br-ex bridge on OpenShift. We will configure a worker node with a high-availability active-backup bond, attach it to an OVS bridge (br-ex), and ensure the node maintains connectivity.

This is our second look into the Kubernetes Gateway API an it’s integration into OpenShift. This post covers TLS configuration.

The Kubernetes Gateway API is new implementation of the ingress, load balancing and service mesh API’s. See upstream for more information.

Also the OpenShift documentation provides an overview of the Gateway API and it’s integration.

We demonstrate how to add TLS to our Nginx deployment, how to implement a shared Gateway and finally how to implement HTTP to HTTPS redirection with the Gateway API. Furthermore we cover how HTTPRoute objects attach to Gateways and dive into ordering of HTTPRoute objects.

This blog post summarizes our first look into the Kubernetes Gateway API and how it is integrated in OpenShift.
