Is Go 1.17 supported by Kubebuilder 3.6.0?

[Gearheads]

Hello, I am new here, and I am trying to use kubebuilder 3.6.0. I appear to be experiencing an issue while running the following command:

% kubebuilder init --domain=my.domain --repo=my.repo
Writing kustomize manifests for you to edit...
Writing scaffold for you to edit...
Get controller runtime:
$ go get sigs.k8s.io/[email protected]
Update dependencies:
$ go mod tidy
go mod tidy: go.mod file indicates go 1.18, but maximum supported version is 1.17
Error: failed to initialize project: unable to run post-scaffold tasks of "base.go.kubebuilder.io/v3": exit status 1
Usage:
  kubebuilder init [flags]

Examples:
  # Initialize a new project with your domain and name in copyright
  kubebuilder init --plugins go/v3 --domain example.org --owner "Your name"

  # Initialize a new project defining a specific project version
  kubebuilder init --plugins go/v3 --project-version 3


Flags:
      --component-config         create a versioned ComponentConfig file, may be 'true' or 'false'
      --domain string            domain for groups (default "my.domain")
      --fetch-deps               ensure dependencies are downloaded (default true)
  -h, --help                     help for init
      --license string           license to use to boilerplate, may be one of 'apache2', 'none' (default "apache2")
      --owner string             owner to add to the copyright
      --project-name string      name of this project
      --project-version string   project version (default "3")
      --repo string              name to use for go module (e.g., github.com/user/repo), defaults to the go package of the current working directory.
      --skip-go-version-check    if specified, skip checking the Go version

Global Flags:
      --plugins strings   plugin keys to be used for this subcommand execution

All of the issues, and discussions, appear to talk about adding support for Go 1.18, and that Go 1.17 should already be supported, so I am not sure if I am doing something wrong?

Has anyone seen this error before, or have any ideas I might be able to try out?

Versions

% go version
go version go1.17.10 darwin/amd64

% kubebuilder version
Version: main.version{KubeBuilderVersion:"3.6.0", KubernetesVendor:"1.24.1", GitCommit:"f20414648f1851ae97997f4a5f8eb4329f450f6d", BuildDate:"2022-08-03T11:47:17Z", GoOs:"darwin", GoArch:"amd64"}

Also, tried other versions of kubebuilder like 3.5.0 and 3.4.1, and so far it looks like the latest version that works with Go 1.17 is 3.4.1:

% kubebuilder init --domain=my.domain --repo=my.repo

Hi @Gearheads,

go mod tidy: go.mod file indicates go 1.18, but maximum supported version is 1.17

As you can see this message came from the Golang when the tool will run go mod tidy. Golang besides being stable and avoiding breaking changes in the releases has some limitations sometimes.

The project as you checked to move forward to support go 1.18 in this way the scaffolds are done using go 1.18 so to use the latest release 3.6.0 you must have installed go 1.18.

We need to indeed update the instruction: https://book.kubebuilder.io/quick-start.html#prerequisites
Also, would be nice to update the code here to avoid the error: https://github.com/kubernetes-sigs/kubebuilder/blob/master/pkg/plugins/golang/v3/init.go#L38

Would you like to help us with it? WDYT?

Hi @camilamacedo86, thank you for the reply and information. I would be happy to help! Should create a new issue, or create one from this discussion?

Hi @Gearheads,

I think we just need a PR to do the updates described above and you can link this discussion in the description. WDYT?
Would you like to contribute?

[Gearheads]

Ok sounds good. Yes, I would be happy to contribute.
