Ian Wienand c110a56ea9 Print unparsable file in pkg-map
As you can see in the CI failures for
Ib11b9df84b593ab25232729a570c812f1b4b8774, you can not see what file
is causing the problems when the parser fails.  Add a print, but raise
the error as it contains the cause.

pkg-map

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.
