community.general.nmcli – Manage Networking

Note

This plugin is part of the community.general collection.

To install it use: ansible-galaxy collection install community.general.

To use it in a playbook, specify: community.general.nmcli.

Synopsis

  • Manage the network devices. Create, modify and manage various connection and device type e.g., ethernet, teams, bonds, vlans etc.
  • On CentOS 8 and Fedora >=29 like systems, the requirements can be met by installing the following packages: NetworkManager-libnm, python3-libsemanage, python3-policycoreutils.
  • On CentOS 7 and Fedora <=28 like systems, the requirements can be met by installing the following packages: NetworkManager-glib, libnm-qt-devel.x86_64, nm-connection-editor.x86_64, python-libsemanage, python-policycoreutils.
  • On Ubuntu and Debian like systems, the requirements can be met by installing the following packages: network-manager, python-dbus (or python3-dbus, depending on the Python version in use), libnm-dev.
  • On older Ubuntu and Debian like systems, the requirements can be met by installing the following packages: network-manager, python-dbus (or python3-dbus, depending on the Python version in use), libnm-glib-dev.
  • On openSUSE, the requirements can be met by installing the following packages: NetworkManager, python2-dbus-python (or python3-dbus-python), typelib-1_0-NMClient-1_0 and typelib-1_0-NetworkManager-1_0.

Requirements

The below requirements are needed on the host that executes this module.
