kustomize VS ketch

kustomize: brew install kustomize

It's a built in feature of kustomize https://github.com/kubernetes-sigs/kustomize/blob/master/api/types/helmchartargs.go

I think the combination of Kustomize and helm works in my experience. For advanced use cases, you can also see KRM functions in Kustomize.

See for instance a related issue: https://github.com/kubernetes-sigs/kustomize/issues/3866

Using a strategic merge is the safest way so you avoid the index fragility.

Rendering out the manifests is something I have been pushing for. Not having to understand how every templating tool works and what actually is being changed is key. Though, it gets complicated when you use helm (or any templating/patching tool) that produces many variants. You also lose any release/deployment time hooks that are provided (helm hooks or recently "patched" kustomize env variables).

Kustomize is an open-source project that “lets you customize raw, template-free YAML files for multiple purposes, leaving the original YAML untouched and usable as is.” It’s now the most popular tool for customizing Kubernetes manifests reasonably, and it’s even built directly into the Kubernetes CLI since K8s v1.14.

Here at Suse we looked at https://github.com/theketchio/ketch and the founder for Acorn did some diligence there. Is it a copy?

An idea may be to look at something like Ketch, and potentially combine it with Pulumi, TF, or others. Here is an example

You have some more “established” tools, such as Ketch but from what I’ve seen, many people are building it in house by using tools such as Helm, Crossplane, or others

Pretty much what Ketch has been doing for a while already, and Ketch is part of a larger app platform

Pretty much what Ketch has been doing for a while now

Another option you have is to use open source projects like Ketch that can make this process more "developer friendly". Here is an example

Because of that, we have created an open-source project called Ketch to make life easier when deploying apps on K8s.

The team is excited about enabling developers to focus on their application code instead of infrastructure. We would love it if you could show your support by starring the project on GitHub and sharing this article with your teammates.

It might be worth having a look at the open source project Ketch

Instead, by combining the application-focused approach from Ketch with the IaC model from Pulumi, developers can have an application-focused layer they can leverage to quickly deploy their applications without getting into the underlying infrastructure details exposed by Kubernetes.
