Is Go 1.18 supported by Kubebuilder 3.4.0?

What broke? What's expected?

Hi, all. I'm starting a new project using Kubebuilder. I already used Kubebuilder before to build some operators, and I saw that there was a new version for Kubebuilder. I also saw that a new Go version was out, so I went to test it out with Kubebuilder.
I entered the Kubebuilder book website and searched for the Quick start page, and there I saw some prerequisites. Reading that, I got a bit confused, because it says: "go version v1.17+ < v1.18 (kubebuilder v3.3+).", so I didn't know if I was able to use 1.17 Go version or 1.18 because it doesn't use ">=" (higher or equal) to describe the version.

Therefore, I went to use Go version 1.18 with Kubebuilder 3.4.0. Created a basic project that plays with the created API and Controller, basically it manages fields values from the CR. Everything worked fine so far.

I would like to know if there's any specific problem by using this Go version (1.18) with this Kubebuilder version (3.4.0).
Thanks in advance!

Reproducing this issue

Commands that I used to scaffold a project.

go mod init github.com/test/mylocal

kubebuilder init --domain test.mylocal

kubebuilder create api --group tester --version v1alpha1 --kind HandsOn

Hi @davisoares454 with Kubebuilder release 3.4.0 there were some updates to help support Go 1.18 in the future. Go 1.18 is not officially supported yet due to some potential dependency compatibility issues. This is information that was given in a Slack post when 3.4.0 was released.

You can find the Slack message that announces the Kubebuilder 3.4.0 release here: https://kubernetes.slack.com/archives/CAR30FCJZ/p1651169166108379

I hope this helps!

I am closing this as duplicated of: #2559
See the comment #2559 (comment) to know what needs to be done for we can support.

The release 3.4.0 still does not support go 1.18.
