Original GitHub issue: https://github.com/fsouza/fake-gcs-server/issues/110

Here's a single use case where I'm:

Creating a bucket "test_bucket"
Uploading a file "foo.txt"
Listing the files (I see "foo.txt")
Downloading the file "foo.txt"

I'm able to do steps 1 to 3. But step for gives me an error, as if it was trying to go the the cloud:

Here's the code sample:

func TestNewGcsStore(t *testing.T) {
	ctx := context.Background()

	server := fakestorage.NewServer(nil)
	server.CreateBucket("bucket_test")
	url := server.URL() + "/storage/v1/"

	transCfg := &http.Transport{
		TLSClientConfig: &tls.Config{InsecureSkipVerify: true}, // ignore expired SSL certificates
	}
	httpClient := &http.Client{Transport: transCfg}
	client, err := storage.NewClient(ctx, option.WithEndpoint(url), option.WithHTTPClient(httpClient))
	if err != nil {
		t.Fatal(err)
	}

	// Create bucket

	bucket := client.Bucket("bucket_test")

	// Create file
	wc := bucket.Object("foo.txt").NewWriter(ctx)

	if _, err = io.Copy(wc, strings.NewReader("Foo content!")); err != nil {
		t.Fatal(err)
	}

	if err := wc.Close(); err != nil {
		t.Fatal(err)
	}

	// List files
	it := bucket.Objects(ctx, nil)
	for {
		attrs, err := it.Next()
		if err == iterator.Done {
			break
		}
		if err != nil {
			t.Fatal(err)
		}
		t.Log(" -> " + attrs.Name)
	}

	// Download file
	rc, err := bucket.Object("foo.txt").NewReader(ctx)
	if err != nil {
		t.Fatal(err)
	}

	data, err := ioutil.ReadAll(rc)
	defer rc.Close()
	if err != nil {
		t.Fatal(err)
	}

	fileContents := string(data)
	t.Log(fileContents)
}

The output is:

=== RUN   TestNewGcsStore
--- FAIL: TestNewGcsStore (0.01s)
    gcsstore_test.go:98:  -> foo.txt
    gcsstore_test.go:104: Get https://storage.googleapis.com/bucket_test/foo.txt: dial tcp: lookup storage.googleapis.com: no such host

Am I missing something or this is a bug?

@aurc commented on GitHub (Oct 25, 2019):

My bad...

Replacing:

server := fakestorage.NewServer(nil)
server.CreateBucket("bucket_test")
url := server.URL() + "/storage/v1/"

transCfg := &http.Transport{
    TLSClientConfig: &tls.Config{InsecureSkipVerify: true}, // ignore expired SSL certificates
}
httpClient := &http.Client{Transport: transCfg}
client, err := storage.NewClient(ctx, option.WithEndpoint(url), option.WithHTTPClient(httpClient))

With

server := fakestorage.NewServer(nil)
server.CreateBucket("bucket_test")
client := server.Client()

did the trick
