@STRRL Thx~ It would be great if you can remove the replacement here, and run go mod tidy to refresh the file go.sum

kubebrain/go.mod

Line 57 in 793d0cf

k8s.io/kubernetes => k8s.io/kubernetes v1.14.8

Updated! PTAL!

I also updated the pseudo version for k8s.io/kube-openapi as the version used in kubernetes 1.20.4

I found other issues when I remove the replace statements in go.mod:

It relates to changes in the interface.

What do you think about it? @divanodestiny

• Keep using replace k8s.io/* dependencies with version 1.14.x, then update dependencies and codes about interface changes in other PR?
• Or make required changes in this PR?

Just keep k8s.io/* dependencies with version 1.14 now，and we will find the way to update them later. It seems that the resourcelock.Interface is changed after v1.18.0-beta.0

got that.

Updated! PTAL! @divanodestiny

PS: I am very pleased to help if you meet some issue when bump the version of kubernetes deps. We (Chaos Mesh Contributors) also make a script for upgrade replace statements in go.mod: https://github.com/chaos-mesh/chaos-mesh/blob/master/hack/update-kubernetes-library.sh

Another thing needs to be mentioned: when I tried to execute go mod tidy, this issue occurs on me:

$ go mod tidy
go: finding module for package github.com/googleapis/gnostic/OpenAPIv2
github.com/kubewharf/kubebrain/pkg/server/service/leader imports
        k8s.io/client-go/tools/leaderelection tested by
        k8s.io/client-go/tools/leaderelection.test imports
        k8s.io/client-go/kubernetes/fake imports
        k8s.io/client-go/discovery imports
        github.com/googleapis/gnostic/OpenAPIv2: module github.com/googleapis/gnostic@latest found (v0.6.9), but does not contain package github.com/googleapis/gnostic/OpenAPIv2

That's a historical issue with kubernetes client-go: kubernetes/client-go#741 (comment)

I am not sure why you did not face this issue. Maybe the (internal) go module proxy server that you used cached an old version for github.com/googleapis/gnostic@latest.

And that's the reason why I replace the github.com/googleapis/gnostic with version v0.3.1

@STRRL Thx for your help~ It seems to work now. I will recheck this PR after merging #2, which sets the actions for UT and lint to run basic checks.

[divanodestiny]

@STRRL hi~ would you mind updating this PR to trigger the workflows, which were set recently.
