Combining Federation V2 and Istio Multicluster

Combining Federation V2 and Istio Multicluster

In a previous post, we saw how to leverage Istio Multicluster to deploy an application (bookinfo) on multiple Red Hat OpenShift clusters and apply mesh policies on all of the deployed services. We also saw that the deployment process was relatively complex. In this post we are going to see how Federation V2 can help […]

Controlling Namespace Configurations

In the Kubernetes namespace model, the high-level idea is that a development team is given access to a namespace. Within the confines of that sandbox, they have the freedom to perform any action they desire. There are, however, a set of namespaced objects whose ownership is not so immediately clear. For example, while it’s obvious […]

Istio Multicluster on OpenShift

Istio Multicluster on OpenShift

Istio Multicluster is a feature of Istio–the basis of Red Hat OpenShift Service Mesh–that allows for the extension of the service mesh across multiple Kubernetes or Red Hat OpenShift clusters. The primary goal of this feature is to enable control of services deployed across multiple clusters with a single control plane. The main requirement for […]

Connecting Multiple OpenShift SDNs with a Network Tunnel

Connecting Multiple OpenShift SDNs with a Network Tunnel

Introduction Istio, the upstream project for Red Hat OpenShift Mesh, has an interesting feature that allows you to extend the service mesh across multiple OpenShift clusters. The main requirement to implement this feature is that the IPs of the pods of the clusters that comprise the service mesh are all routable between each other. That […]

An Open Source Load Balancer for OpenShift

An Open Source Load Balancer for OpenShift

Introduction A highly-available deployment of OpenShift needs at least two load balancers: One to load balance the control plane (the master API endpoints) and one for the data plane (the application routers). In most on-premise deployments, we use appliance-based load balancers (such as F5 or Netscaler). The architecture looks like the following: In this architecture, […]
