[TheoBrigitte]

This PR updates controller-gen to v0.14.0 in order to get rid of a bug impeding the make manifest and make generate commands

It also simplifies the installation process for controller-gen

Hi @TheoBrigitte, I don't think there was a report of such a bug. Can you please expand on how to repeat the bug? Does it depend on specific versions of other tooling?

[TheoBrigitte]

To my understanding the tools needed are go and make

Here is my environment

$ go version
go version go1.22.0 linux/amd64
$ make --version
GNU Make 4.4.1
Built for x86_64-pc-linux-gnu

$ uname -a
Linux x1 5.15.154-1-MANJARO #1 SMP PREEMPT Wed Apr 10 19:10:26 UTC 2024 x86_64 GNU/Linux

How to reproduce

$ rm $(which controller-gen)
$ make manifests
<same error as above>

[yorugac]

OK, thanks. It seems it happens with Golang 1.22: k6-operator is at 1.21 now.
For reference:

• Controller-gen panic when using go 1.22 kubernetes-sigs/controller-tools#880
• go/types: sigs.k8s.io/controller-tools/cmd/controller-gen crashes on 1.22 golang/go#65637

I'll need to look into those in detail before returning to this PR. It'd be nice if there was another workaround...
But Go 1.21 should work.

[yorugac]

After some looking around and testing, I think it should be good to go ahead with this change. Thanks again, @TheoBrigitte!
