A short article on how to deploy an application into multiple Kubernetes clusters using ArgoCD. And also Vcluster and Kyverno.

It starts with cluster creation and walks you through the whole thing up to a running app. An interesting point for me was an ability of Kyverno to create resources based on event. I didn’t know about this ability and it seems very powerful (now, I’m wondering if one can create a resource in a cluster by an event in another using Kyverno).

However, I’ve missed some things here as well. It’s not like an example is a “hello world” one, it’s fine. Yet, I would appreciate it, if there were more in-depth glance into Argo. How does it manage an app in several clusters? Can one use multiple clusters for HA purposes, but abstract an app via Argo? What would happen if one needs an odd number of replicas, how is it going to be distributed between clusters?

If you know the answer, I’d be happy to have a chat with you. Also, if you have an article on that, I would happily check it out and also share it here!
