README.md

Map package names to distro specific packages.

Provides the following:

  • bin/pkg-map

    usage: pkg-map [-h] [--element ELEMENT] [--distro DISTRO]

    Translate package name to distro specific name.

    optional arguments: -h, --help show this help message and exit --element ELEMENT The element (namespace) to use for translation. --distro DISTRO The distro name to use for translation. Defaults to DISTRO_NAME

  • Any element may create its own pkg-map JSON config file using the one of 3 sections for the distro/family/ and or default. The family is set automatically within pkg-map based on the supplied distro name. Families include:

    • redhat: includes centos, fedora, and rhel distros
    • debian: includes debian and ubuntu distros
    • suse: includes the opensuse distro

    The most specific section takes priority. An empty package list can be provided. Example for Nova and Glance (NOTE: using fictitious package names for Fedora and package mapping for suse family to provide a good example!)

    Example format: { "distro": { "fedora": { "nova_package": "openstack-compute", "glance_package": "openstack-image" } }, "family": { "redhat": { "nova_package": "openstack-nova", "glance_package": "openstack-glance" }, "suse": { "nova_package": "" } }, "default": { "nova_package": "nova", "glance_package": "glance" } }

    Example commands using this format:

    pkg-map --element nova-compute --distro fedora nova_package

    Returns: openstack-compute

    pkg-map --element nova-compute --distro rhel nova_package

    Returns: openstack-nova

    pkg-map --element nova-compute --distro ubuntu nova_package

    Returns: nova

    pkg-map --element nova-compute --distro opensuse nova_package

    Returns:

  • This output can be used to filter what other tools actually install (install-packages can be modified to use this for example)

  • Individual pkg-map files live within each element. For example if you are created an Apache element your pkg-map JSON file should be created at elements/apache/pkg-map.
