Glance formula
==============

The Glance project provides services for discovering, registering, and
retrieving virtual machine images. Glance has a RESTful API that allows
querying of VM image metadata as well as retrieval of the actual image.


Sample pillars
==============

.. code-block:: yaml

    glance:
      server:
        enabled: true
        version: juno
        workers: 8
        policy:
          publicize_image:
            - "role:admin"
            - "role:image_manager"
        database:
          engine: mysql
          host: 127.0.0.1
          port: 3306
          name: glance
          user: glance
          password: pwd
        identity:
          engine: keystone
          host: 127.0.0.1
          port: 35357
          tenant: service
          user: glance
          password: pwd
        message_queue:
          engine: rabbitmq
          host: 127.0.0.1
          port: 5672
          user: openstack
          password: pwd
          virtual_host: '/openstack'
        storage:
          engine: file
        images:
        - name: "CirrOS 0.3.1"
          format: qcow2
          file: cirros-0.3.1-x86_64-disk.img
          source: http://cdn.download.cirros-cloud.net/0.3.1/cirros-0.3.1-x86_64-disk.img
          public: true
        audit:
          enabled: false
        api_limit_max: 100
        limit_param_default: 50

The pagination is controlled by the *api_limit_max* and *limit_param_default*
parameters as shown above:

* *api_limit_max* defines the maximum number of records that the server will
  return.

* *limit_param_default* is the default *limit* parameter that
  applies if the request didn't defined it explicitly.

Documentation and Bugs
======================

To learn how to deploy OpenStack Salt, consult the documentation available
online at:

    https://wiki.openstack.org/wiki/OpenStackSalt

In the unfortunate event that bugs are discovered, they should be reported to
the appropriate bug tracker. If you obtained the software from a 3rd party
operating system vendor, it is often wise to use their own bug tracker for
reporting problems. In all other cases use the master OpenStack bug tracker,
available at:

    http://bugs.launchpad.net/openstack-salt

Developers wishing to work on the OpenStack Salt project should always base
their work on the latest formulas code, available from the master GIT
repository at:

    https://git.openstack.org/cgit/openstack/salt-formula-glance

Developers should also join the discussion on the IRC list, at:

    https://wiki.openstack.org/wiki/Meetings/openstack-salt

Documentation and Bugs

In the unfortunate event that bugs are discovered, they should be reported to
the appropriate issue tracker. Use Github issue tracker for specific salt
formula:

For feature requests, bug reports or blueprints affecting entire ecosystem,
use Launchpad salt-formulas project:

    https://launchpad.net/salt-formulas

You can also join salt-formulas-users team and subscribe to mailing list:
