Thank you!

I'm curious why you want to install kubelet using aqua.

[takumin]

I think it's a very niche use case, but there are two points:

• Declarative installation of related tools in the Kubernetes The Hardway document
• Adoption as a declarative package manager in a new Linux distribution that I am personally working on as a PoC

I would like to prepare the former mainly for myself, as an environment for use within my company.

I think that combining it with a MicroVM solution (firecracker or cloud-hypervisor + virtiofsd) will make it easy to build a testing environment with various variations.

As for the latter, it is a true PoC, and there are various remnants of past attempts, but my current conclusion is that the package manager itself needs to have declarative installation functionality.

Recently, there have been things like NixOS(or Wolfi OS), but my need is compatibility with existing distributions, and in that respect aqua's design is excellent, so I would like to actively adopt it.

[suzuki-shunsuke]

Thank you for your explanation.
I see. It's interesting.

[takumin]

Is merging difficult?
I'm thinking of using it with limavm, but if merging isn't possible, I'll create my own registry to deal with the issue, so I'd like to know your opinion.

[suzuki-shunsuke]

Sorry. I think we can merge this, but now I'm a bit busy.
And I'm also working on the performance improvement of aqua to prevent huge registry.yaml from making the performance worse.

Thank you for your understanding.

To update this package using Renovate, I think we should rename this to kubernetes/kubernetes/kubelet.
If the package is kubernetes/kubelet, Renovate gets versions from https://github.com/kubernetes/kubelet , which doesn't work well.

@suzuki-shunsuke
Thank you for merging.
There was one thing I didn't understand, so please let me clarify your intention.
The following file doesn't seem to have been moved. Is this intentional?

https://github.com/aquaproj/aqua-registry/blob/main/pkgs/kubernetes/kubelet/scaffold.yaml

Incorrect:
pkgs/kubernetes/kubelet/scaffold.yaml
Correct:
pkgs/kubernetes/kubernetes/kubelet/scaffold.yaml

If this is unintentional, I will submit a PR to fix it.
Thanks for taking the time to review this. Your feedback is always helpful, especially given your busy schedule.

[suzuki-shunsuke]

Oh, this isn't intentional.

aqua-registry mv command doesn't support scaffold.yaml, so I didn't move it mistakenly.

https://github.com/aquaproj/registry-tool/blob/b71abab94846f9ad0150e947e1977128ed5a64d6/pkg/mv/api.go#L27-L33

[suzuki-shunsuke]

I'll fix registry-tool.
