ReferenceExpand causes image lookup failures with containerd image store about linuxkit

[jalaziz]

I was able to reproduce the issue by testing with this simple Go program:

package main

import (
	"github.com/containerd/containerd/reference"
	"github.com/linuxkit/linuxkit/src/cmd/linuxkit/docker"
	"github.com/linuxkit/linuxkit/src/cmd/linuxkit/util"
	log "github.com/sirupsen/logrus"
)

func main() {
	// Create a new client
	cli, err := docker.Client()
	if err != nil {
		log.Fatal(err)
	}

	imageName := util.ReferenceExpand("bastion.io/foo:local")
	ref, err := reference.Parse(imageName)
	if err != nil {
		log.Errorf("could not resolve references for image %s: %v", imageName, err)
	}

	// Check if the image is in the cache
	err = docker.HasImage(&ref)
	if err != nil {
		log.Fatal(err)
	}

	// Inspect the image
	inspect, err := docker.InspectImage(cli, &ref)
	if err != nil {
		log.Fatal(err)
	}

	log.Println(inspect)
}
