Client-go: Building with go modules suddenly returns 'cannot find module providing package'

[SimonTheLeg]

Hi there,

I've been using client-go in combination with go modules and got it to work last week. However suddenly it fails with the following message:

go: finding k8s.io/api/admissionregistration/v1alpha1 latest
go: finding k8s.io/api/admissionregistration latest
go: finding k8s.io/api latest
/Users/simonbein/.gvm/pkgsets/go1.11.2/global/pkg/mod/k8s.io/[email protected]+incompatible/kubernetes/scheme/register.go:22:2: unknown import path "k8s.io/api/admissionregistration
/v1alpha1": cannot find module providing package k8s.io/api/admissionregistration/v1alpha1

Go modules seems to be correctly set-up in the project as I am able to resolve other dependencies (e.g. logrus) without any issues.

Steps to reproduce

1. Create a project outside $GOPATH.
2. run _go mod init [great-module-name]_
3. Write some code that imports packages from client-go, like so

package main

import (
    "k8s.io/client-go/rest"
    "k8s.io/client-go/tools/clientcmd"
    "k8s.io/client-go/kubernetes"
    "path/filepath"
    "os"
    "fmt"
)

func main() {
    var config *rest.Config

    kubecfgpath := filepath.Join(os.Getenv("HOME"), ".kube", "config")
    config, err := clientcmd.BuildConfigFromFlags("", kubecfgpath)

    clientset, err := kubernetes.NewForConfig(config)

    // Please handle errors differently in your code ;)
    if err != nil {
        panic(err)
    }

    fmt.Println(clientset)

}

1. run _go build_

k8s.io/api v0.0.0-20190126160303 indicates it is pulling from the master branch of k8s.io/api (and other k8s dependencies)

That alpha API was just recently removed in master in preparation for 1.14

you need to either pull from the master branch of client-go as well, or pin the dependencies to a release branch rather than master

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

[SimonTheLeg]

Thank you very much for the answer, it is exactly like you said :)

Quick addition for all fellow go beginners who might come across this thread, here's how I got it to work using dependency pinning:

Add the following to your _go.mod_ file

require (
    k8s.io/api kubernetes-1.13.2
    k8s.io/client-go v10.0.0
)

(You can find a list of all available tags for the api package here https://github.com/kubernetes/api/tags)

[EmandM]

My build is also failing with this message, and the above fix is not working. Any further idea on how to fix this?

[irvifa]

I manage to fix this issue by removing indirect dependency, change the version to:

require (
    k8s.io/api kubernetes-1.13.2
    k8s.io/client-go v10.0.0
)

and do go mod tidy

[jsravn]

Is this still working for everyone? It is not working for me at all.

1. start with a clean GOPATH
2. create go.mod as in https://github.com/kubernetes/client-go/issues/551#issuecomment-462619473
3. go build ./... blows up with imports k8s.io/api/admissionregistration/v1alpha1: unknown import path "k8s.io/api/admissionregistration/v1alpha1": cannot find module providing package k8s.io/api/admissionregistration/v1alpha1

[sttts]

The master branch has no admissionregistration/v1alpha1 anymore (1.13 did have it). That suggests that you vendor the master branch.

[jsravn]

Odd, so for some reason it's ignoring kubernetes-1.13.2 which I've specified in go.mod. I will keep digging, thanks.

edit: I was mistaken. I was using kubernetes-1.13.3 tag which breaks with the above error. Switching to kubernetes-1.13.2 seems to have the same problem (when starting from a clean gopath), so not sure what's going on.

update: Swapping k8s.io/api and k8s.io/client-go to kubernetes-1.12.5 seems to work. 1.13 seems broken, for me at least.

[discordianfish]

I have the same problem. I think this can be reproduced by just starting fresh right now. Something is probably pulling in the v1alpha1 dependency. I don't directly depend on it at least.

[liggitt]

specify matching versions of all three k8s.io/... components in your go.mod file, for example:

require (
    k8s.io/api kubernetes-1.14.1
    k8s.io/apimachinery kubernetes-1.14.1
    k8s.io/client-go kubernetes-1.14.1
)

if you want to be extra super sure that you are not using newer versions (even if some of your other dependencies want to), you can pin those versions in your top-level go.mod file:

replace (
    k8s.io/api => k8s.io/api kubernetes-1.14.1
    k8s.io/apimachinery => k8s.io/apimachinery kubernetes-1.14.1
    k8s.io/client-go => k8s.io/client-go kubernetes-1.14.1
)

opened https://github.com/kubernetes/kubernetes/pull/75595/files to update client-go INSTALL.md instructions with go module details

[jsravn]

It is working for me now on go 1.12.1 with the requirements @liggitt posted.

[onethirdzero]

None of the steps above worked for me initially.

However, running go clean -modcache, _and then_ pinning the k8s.io/... components like @liggitt suggested, followed by go mod tidy fixed things for me.

[metacosm]

None of this is working if I try to use the kubernetes-1.14.1 tag…

[liggitt]

if I try to use the kubernetes-1.14.1 tag…

that requires client-go v11.0.0 (or you can use the kubernetes-1.14.1 tag for that as well)

if that doesn't work for you, can you provide your complete go.mod file?

[metacosm]

D'oh! Thank you, @liggitt!

[mjpitz]

I'm running into an issue where even after pinning these versions, specifying the replaces, and running the go clean -modcache, go goes in and replaces with the versions from master despite pinning these versions.

[liggitt]

go goes in and replaces with the versions from master despite pinning these versions.

go will update require statements to reflect the maximal version desired among all your dependencies. however, the replace directives will govern what is actually used in the build.

running GO111MODULE=on go mod graph | grep k8s.io might help narrow down what dependency is bumping your require directives back up to master

[joshmsamuels]

@liggitt I am running into the same issue. Even the versions in the replace directive are being replaced.

[salilgupta1]

For posterity, I ran into the same issue. I was pinning all my k8s.io dependencies to kubernetes-1.15.0 and I was using the replace directive to be extra sure that it would use the appropriate tag. However, go was still complaining that the k8s.io/api/core/v1 package didn't exist. In the end, I was able to resolve my issue by pinning to kubernetes-1.14.6 tag. I also cleaned my cache i.e. go clean -modcache.

Is there something up with the 1.15.0 tag?

[ndascanio-asapp]

copy from kubebuilder

    k8s.io/api v0.17.2
    k8s.io/apimachinery v0.17.2
    k8s.io/client-go v0.17.2

For my case, I just need to keep client-go version the same as k8s.io/apimachinery

require (
    k8s.io/apimachinery v0.19.1
    k8s.io/client-go v10.0.0+incompatible
)

replace (
    k8s.io/client-go => k8s.io/client-go v0.19.1
)

[liggitt]

this will accomplish the same thing:

require (
    k8s.io/apimachinery v0.19.1
    k8s.io/client-go v0.19.1
)

[chenrui333]

@liggitt I tried that, but failed, I think that one is some transitive dep?

[kris-nova]

For anyone trying to use 1.19 client-go I found this was what I needed to use

go mod init
go mod vendor
go mod download

Running Go 1.15

// go.mod

require (
    k8s.io/api v0.19.1
    k8s.io/apimachinery v0.19.1
    k8s.io/client-go v0.19.1
)

Took me a while to find this - adding the language above to help others looking for a solution here. Also important to note that I had to reset my cache from building was a previous version of the libraries as well.
