OpenShift Service Mesh 3: multi-cluster with ACM and Kiali

Thu, 23 Jul 2026 00:00:00 -0300

Multi-cluster with a service mesh usually fails on the boring detail: meshID, clusterName, and network have to match everywhere. If one diverges, Kiali shows half a topology or inter-cluster traffic never finishes the handshake. Installing the control plane twice does not fix that.

In the post about OpenShift Service Mesh 3 I covered the move from Maistra to upstream Istio. This is the next step: two spokes in the same multi-primary mesh, with ACM on the hub.

Skupper workshop: Patient Portal on Kubernetes

Description

This workshop introduces Red Hat Service Interconnect, an application integration solution that lets different systems communicate efficiently and securely.

Solution architecture

Service topology

Workshop outline

Sign in to Red Hat Developer.
Create an OpenShift cluster.
Access the OpenShift cluster.
In the Red Hat OpenShift Sandbox project, open your project.
Create a virtual machine with OpenShift Virtualization.
Install packages on the virtual machine:
- podman
- kubernetes-client
- skupper
- oc
- wget
Deploy the database with Podman.
Deploy the application frontend and backend.
Configure Service Interconnect (Skupper) so the database running under Podman can talk to the app on OpenShift.
Access the application and confirm communication works.
Closing notes.

References and technologies used

Tools

A computer with minikube [2] installed;
A terminal to run the commands;
kubectl > 1.15 [6] or newer.

Solution overview

Skupper [1] lets you connect two or more cloud environments in a non-intrusive, secure way. Those environments can sit on different cloud providers—AWS, GCP, Azure, and others—or on native Kubernetes clusters.
