Update for version 8.0.0, the Master branch of the repo is in version 7.1.0 but there are version 8.0.0 by this reason was need to included the commit https://github.com/akretion/docky/pull/157/commits/1beea3c329e606cd476f69e06fe65dc3d5154c62 in Docker Compose V2 PR https://github.com/akretion/docky/pull/157, to keep Versions in order, but I think will be better to solve it here to reduce code to review and maybe solve the conflict file.
