Error deleting image when defining containerd.sock path

E1023 12:38:30.121874       1 image_manager.go:492] error deleting image '<image>' from node '<node-name>': Job.batch "test-imagecache-q955z" is invalid: [spec.template.spec.volumes[0].hostPath.path: Required value, spec.template.spec.containers[0].volumeMounts[0].name: Not found: "runtime-sock", spec.template.spec.containers[0].volumeMounts[0].mountPath: Required value] 

I think it is because the socketPath is empty when criSocketPath is not empty. (The same goes for the following two if blocks)

kube-fledged/pkg/images/image_helpers.go

Lines 229 to 231 in 6765db5

	if criSocketPath == "" {
	socketPath = "/run/containerd/containerd.sock"
	}
