Otherwise, it is recommended to install the docker Python module. Note that both modules should not be installed at the same time. Also note that when both modules are installed and one of them is uninstalled, the other might no longer function and a reinstall of it is required.
• Docker SDK for Python >= 1.10.0 (use docker-py for Python 2.6)
