client-go 0.23.5 run blocked

[regnaio]

Using go 1.18.1 or go 1.17.9 and client-go 0.23.5

go run <script using client-go>

# k8s.io/client-go/applyconfigurations/meta/v1
/go/pkg/mod/k8s.io/client-go@v0.23.5/applyconfigurations/meta/v1/unstructured.go:64:38: cannot use doc (variable of type *"github.com/googleapis/gnostic/openapiv2".Document) as type *"github.com/google/gnostic/openapiv2".Document in argument to proto.NewOpenAPIData

It helped reverting client-go to v0.22.8 for me. Just a work around though.

make sure you have matching client-go and other k8s.io/... module versions

[liggitt]

(and are using the version of k8s.io/kube-openapi indicated by your version of client-go)

[liggitt]

I suspect you are trying to use HEAD of k8s.io/kube-openapi with v0.23.5 of client-go

[liggitt]

client-go 0.23.5 uses this version of kube-openapi:

k8s.io/kube-openapi v0.0.0-20211115234752-e816edb12b65

https://github.com/kubernetes/kube-openapi/commits/master/pkg/util/proto shows the history of that file, which changed the signature of that method from googleapis/gnostic → google/gnostic on 3/10/2022

the error you're getting indicates you were using a version of kube-openapi >= 3/10/2022 in your build

client-go 0.23.5 uses this version of kube-openapi:

k8s.io/kube-openapi v0.0.0-20211115234752-e816edb12b65

just add replace k8s.io/kube-openapi => k8s.io/kube-openapi v0.0.0-20211115234752-e816edb12b65 and it works, thanks a lot!

The problem came up again this week from this pr in kube-openapi.

I solved it today by updating client-go to include this commit.

Warning this is not a long term fix and should only be used if necessary and until v0.28.0 is stable.

// go.mod
replace k8s.io/client-go => k8s.io/client-go v0.28.0-alpha.2

[lowang-bh]

also met this error with client-go v0.27.0~v0.27.2
