This is a minimal reproduction of a bug I have found when using the fake ClientSet from k8s.io/client-go@v0.18.2.
This repo contains a single test, it uses the fake.NewSimpleClientset to test an informer.
In my local environment with Go 1.15, this test passes
$ go version
go version go1.15.6 linux/amd64
$ make test
go test -v -count=1 ./...
=== RUN Test_kubernetestFakeFailure
--- PASS: Test_kubernetestFakeFailure (0.00s)
PASS
ok github.com/LucasRoesler/buildx-bug 0.009sBut this test fails when run inside a docker build using buildx to produce a multiach build for amd/intel + arm.
