Kubebuilder inits in go1.16 and pkgs miss methods later on

[nikfot]

What broke? What's expected?

I am followin the basic tutorial documentation, just instead of creating a CronJob I try it out with a deployment. It initiates the env with go1.16 in go.mod.

Later on, when running kubebuilder create api --group apps --version v1 --kind Deployment I get errors saying Deployment struct is missing DeepCopy method.

When changing the version in go.mod and running go mod tidy it fixes all issues.

Reproducing this issue

1. kubebuilder init --domain tutorial.kubebuilder.io --repo tutorial.kubebuilder.io/project
2. kubebuilder create api --group apps --version v1 --kind Deployment

Hi @nikfot,

You are using Kubebuilder v3.0.0 right? So, the go version supported for it is 1.15 : https://github.com/kubernetes-sigs/kubebuilder/blob/v3.0.0/go.mod#L3

Please, see the comment: #2512 (comment)

Also, could you please check if your issue scenario can be reproduced with the latest KB release and go 1.17+?

Hello @camilamacedo86 ,

I now sow the copatibility matrix between kubebuilder and go, although I was on master so I thought it was enough in the first place.

Anyway, I installed kubebuilder v3.3.0 and the issue is fixed.

Thanks!
