Upgrading from 1.5

  • Components were split into subpackages. List of components:

    • admin
      • koschei-admin script and database migrations
    • backend
      • backend services. Recommended to run on machine that has recent
        versions of libsolv+hawkey stack installed, i.e. on Fedora
    • backend-fedora
      • Fedora specific bits of backend - fedmsg watcher service,
        fedmsg_publisher plugin, pkgdb plugin
    • frontend
      • WSGI frontend. Doesn't use fedmsg, koji or depsolver anymore, can be
        therefore deployed on less bleeding-edge configurations, such as RHEL 7
    • frontend-fedora
      • Fedora-specific bits for frontend. Currently only pkgdb plugin.

  • Configuration split - there are separate configuration files for components:

    • /etc/koschei/config-backend.cfg
    • /etc/koschei/config-frontend.cfg
    • /etc/koschei/config-admin.cfg - used by koschei-admin and also alembic migrations

    During the upgrade, the central configuration file /etc/koschei/config.cfg
    needs to be split into those three. The configuration format and options
    didn't change from previous release. Therefore the upgrade can be done by
    copying the former config.cfg file to the 3 locations above and removing
    configuration options that are irrelevant for each given component.

  • Plugins are now turned off by default and have to be explicitly enabled in
    plugin section of the configuration. For example "plugins": ["pkgdb"].

  • Database migration

    • run alembic -c /usr/share/koschei/alembic.ini upgrade head while the
      services and httpd are stopped
