  • name – Name of the plugin that will be in the plugin’s RPM file name. The allowed name characters are lowercase letters, dash -, and underscore _.

  • title – Human-readable plugin name displayed on the Fuel web UI.

  • version – Plugin version. For guidelines, see Plugin versioning system.

  • fuel_version – The Fuel version that your plugin is compatible with. Currently, the builder verifies fuel_version only against package_version. The package_version field must be supported by the Fuel versions listed at the bottom of this section. Leaving this field empty will skip the check. For format guidelines, see _ClassType StrictVersion.

  • licenses – List the licenses under which your plugin can be distributed.

  • authors – Name of the plugin author. A company or an individual.

  • homepage – A link to page with your plugin. This can be your plugin’s GitHub repository page.

  • is_hotpluggable – State if the plugin is hot-pluggable. See Hot-pluggable plugins.

  • groups – A group to which your plugin belongs in the Fuel web UI.

  • releases – A list of OpenStack releases compatible with the plugin.

    • releases: os – A compatible Linux distribution for the plugin. The supported values are ubuntu and centos. Fuel 8.0 supports only Ubuntu.
    • releases: version – A compatible OpenStack release version. Fuel Plugin Builder does not validate the releases: version field; but if there is no OpenStack release with the same version on the Fuel Master, the user cannot enable the plugin. See also a note in Install Fuel Plugin Builder.
    • releases: mode – A list of compatible cluster deployment modes. Fuel 8.0 supports only the haz value.
    • releases: deployment_scripts_path – A path in your plugin directory where all the deployment scripts for the release are. The path is relative to the plugin root.
    • releases: repository_path – A path in your plugin directory where all the packages for the release are. Relative to the plugin root.
  • package_version – A version of the compatible plugin format. To build your plugin, the Fuel Plugin Builder version must be the same as the version of the compatible plugin format or newer. Each new plugin format version introduces new features and, possibly, deprecates some of the old ones. The Fuel master node must support the specific package_version, otherwise, you cannot install the plugin.

    The table below shows the existing plugin format versions and the versions of Fuel starting from which they are supported:

    Plugin format 1.0.0 2.0.0 3.0.0 4.0.0 5.0.0
    Fuel 6.0 6.1 7.0 8.0 9.0
  • build_version – A version of the build that allows to iterate package version without updating the plugin version.
