  labels:
    env: dev

So we call tarutil.build

hydros/pkg/images/controller.go

Line 170 in 2d35fa0

if err := tarutil.Build(transformed, tarFilePath); err != nil {

This should end up calling copyLocalPath here

hydros/pkg/tarutil/builder.go

Line 77 in 2d35fa0

if err := copyLocalPath(tw, s); err != nil {

The only scheme that is supported is file

hydros/pkg/tarutil/builder.go

Line 95 in 2d35fa0

if u.Scheme != "file" {

So why would this ever work with a git or https scheme?

Its because when we do build we automatically replace the remotes here

hydros/pkg/images/controller.go

Line 137 in 2d35fa0

if err := c.replaceRemotes(ctx, image); err != nil {

So if there is a problem replacing the remote then we don't get a file URI.

At the very least we should probably surface a more actionable error message somewhere for the user.
