The `glasskube install` command does a bunch of stuff that ends up as resources in your Kubernetes cluster, that are then interpreted by the Glasskube operator.
The "Gitops template" make use of ArgoCD and Git to do what `glasskube install` would have done.
I am not super thrilled about critical applications like Argo getting a plethora of plugins, otherwise we end up looping back to Jenkins and plugin hell
On-topic: Glasskube isn't really an ArgoCD plugin as it can work standalone, but in 2024, can you really propose a package manager for k8s without having some integration with ArgoCD and GitOps in general?
If you want to migrate, having interoperability between the tools can make the process smoother. And if you don't want to migrate and still benefit from a centralized, curated, audited repository of packages for Kubernetes so that your "Powered by ArgoCD" GitOps are easier to manage, that's what the GitOps template propose.
In Debian, you can just `apt install <that big thing i don't want to write a deploy script for>`. Imagine doing that with the usual big operators you want in your cluster (cert-manager, a hashicorp vault operator, istio or nginx ingress controller or envoy or ...)
I certainly prefer FluxCD, myself.
FluxCD is fully batteries-included, but the UI (3rd party!) leaves a lot to be desired, and turns off a lot of developers, and as a result makes it difficult to get team buy-in
ArgoCD is missing some critical systems, like how to tell when the underlying image needs updating. There are a number of ways to handle this but it's either a kludge, a plugin, or both. However, the UI is fantastic and very easy to pickup and understand, team buy-in is usually close to 100%
I generally recommend starting with argo, and once the team/project/s have matured, migrate to FluxCD. Eventually you want to lock everyone out of the CD system, but initially people are skeptical and want to understand/watch everything work, especially during debug.
