Description of problem: When I mirror the image to a repo, get the Golang panic. I know the right usage is "openshift-tests images --to-repository repo/registry/xxx", however, it should not generate panic even if we specify the repo only. [root@preserve-olm-env origin]# ./openshift-tests images --to-repository jiazha0210.mirror-registry.qe.azure.devcluster.openshift.com:5000 panic: runtime error: index out of range [1] with length 1 goroutine 1 [running]: k8s.io/kubernetes/test/utils/image.mapConfigToRepos(0x9, 0x5e0977e, 0x21, 0x5d7f9c5, 0xf, 0x5d54dc3, 0x3, 0x0, 0x0, 0x0, ...) k8s.io/kubernetes.0/test/utils/image/manifest.go:292 +0x620 k8s.io/kubernetes/test/utils/image.GetMappedImageConfigs(0xc0004a1650, 0x0, 0x0, 0x0) k8s.io/kubernetes.0/test/utils/image/manifest.go:275 +0x20b main.createImageMirrorForInternalImages(0x0, 0x0, 0xc001e6eaa0, 0x41, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, ...) github.com/openshift/origin/cmd/openshift-tests/images.go:54 +0xc6 main.newImagesCommand.func1(0xc000ffeb00, 0xc001e6d180, 0x0, 0x2, 0x0, 0x0) github.com/openshift/origin/cmd/openshift-tests/openshift-tests.go:177 +0x297 github.com/spf13/cobra.(*Command).execute(0xc000ffeb00, 0xc001e6d160, 0x2, 0x2, 0xc000ffeb00, 0xc001e6d160) github.com/spf13/cobra.1/command.go:850 +0x453 github.com/spf13/cobra.(*Command).ExecuteC(0xc000ffe000, 0x0, 0x6b6a8e0, 0xa0a22e0) github.com/spf13/cobra.1/command.go:958 +0x349 github.com/spf13/cobra.(*Command).Execute(...) github.com/spf13/cobra.1/command.go:895 main.main.func1(0xc000ffe000, 0x0, 0x0) github.com/openshift/origin/cmd/openshift-tests/openshift-tests.go:84 +0x94 main.main() github.com/openshift/origin/cmd/openshift-tests/openshift-tests.go:85 +0x3e4 Version-Release number of selected component (if applicable): the master branch of origin, openshift-tests version: v4.1.0-3600-gaf3f04c How reproducible: always Steps to Reproduce: 1.
