When deploying a stack using a relative path as bind-mount source in the compose file, the CLI converts the relative path to an absolute path, relative to the location of the docker-compose file. This causes a problem when deploying a stack that uses an absolute Windows path, because a non-Windows client will fail to detect that the path (e.g. `C:\somedir`) is an absolute path (and not a relative directory named `C:\`). The existing code did already take Windows clients deploying a Linux stack into account (by checking if the path had a leading slash). This patch adds the reverse, and adds detection for Windows absolute paths on non-Windows clients. The code used to detect Windows absolute paths is copied from the Golang filepath package; https://github.com/golang/go/blob/1d0e94b1e13d5e8a323a63cd1cc1ef95290c9c36/src/path/filepath/path_windows.go#L12-L65 Signed-off-by: Sebastiaan van Stijn <[email protected]> (cherry picked from commit d6dd08d) Signed-off-by: Sebastiaan van Stijn <[email protected]>
