Function RepositoryScope

core/remotes/docker/scope.go:32–42

RepositoryScope returns a repository scope string such as "repository:foo/bar:pull" for "host/foo/bar:baz". When push is true, both pull and push are added to the scope.

(refspec reference.Spec, push bool)

// for "host/foo/bar:baz".
// When push is true, both pull and push are added to the scope.
func RepositoryScope(refspec reference.Spec, push bool) (string, error) {
	u, err := url.Parse("dummy://" + refspec.Locator)
	if err != nil {
		return "", err
	}
	s := "repository:" + strings.TrimPrefix(u.Path, "/") + ":pull"
	if push {
		s += ",push"
	}
	return s, nil
}

// tokenScopesKey is used for the key for context.WithValue().
// value: []string (e.g. {"registry:foo/bar:pull"})
