Controller-runtime does not compile with client-go 1.31 with version v0.18.5

[howardjohn]

Reproducer:

main.go:

package main

import (
        _ "k8s.io/client-go"
        _ "sigs.k8s.io/controller-runtime/pkg/client/fake"
)

func main() {
}

go.mod:

module test

go 1.22.6

require sigs.k8s.io/controller-runtime v0.18.5

require k8s.io/client-go v0.31.0

Gives:

$ go build .

Broken by kubernetes/kubernetes#125560

[howardjohn]

In the past sometimes we have done tricks to support both versions concurrently. I don't see how we can do it in this case

I am impacted by this as well.

[sbueringer]

While this is not great, it is not something that we guarantee to support, see: https://github.com/kubernetes-sigs/controller-runtime#compatibility

[jpbetz]

Can anyone impacted verify that if they upgrade client-go into the supported skew range that the problem is resolved?

[howardjohn]

Ah I looked for a newer CR release but didn't see it since where I was looking filtered out 0.19 due to the -beta suffix. At least in my example reproducer that does seem to compile.

[sbueringer]

Ah, makes sense! Yup 0.19 would be the correct release for k8s.io/* 1.31.0

I think we'll release it soon. Last thing we want to get done before is this one: #2901 (at least as far as I'm aware)
