Dear bug triager. This bug was created since a commit was marked with DOCIMPACT.
Your project "openstack/openstack-ansible" is set up so that we directly report the documentation bugs against it. If this needs changing, the docimpact-group option needs to be added for the project. You can ask the OpenStack infra team (#openstack-infra on freenode) for help if you need to.

    Allow for multiple store backends for Glance

    This implementation will add a new `user_variables.yml` override
    glance_additional_stores which is set with the default values http, cinder
    The operator can now independently enable Glance store protocols besides
    glance_default_store.

    A example configuration can be

    glance_default_store = rbd
    glance_additional_stores:
      - swift
      - http
      - cinder

    to maintain glance images over RBD and Swift/HTTP.
    This is particular useful when adding new storage protocols
    to glance while retaining access to the existing protocols/images.
