Description

This cookbook installs the OpenStack Image service Glance as part of an OpenStack reference deployment Chef for OpenStack. The http://github.com/mattray/chef-openstack-repo contains documentation for using this cookbook in the context of a full OpenStack deployment. Glance is installed from packages, optionally populating the repository with default images.

Requirements

Chef 0.10.0 or higher required (for Chef environment use).

Cookbooks

The following cookbooks are dependencies:

• database
• mysql
• openstack-common
• openstack-identity

Usage

api

• Installs the image-api server

registry

• Installs the image-registry server

keystone-registration

• Registers the API endpoint and glance service Keystone user

db

• Creates the Glance registry database

The Glance cookbook currently supports file, swift, and Rackspace Cloud Files (swift API compliant) backing stores. NOTE: changing the storage location from cloudfiles to swift (and vice versa) requires that you manually export and import your stored images.

To enable these features set the following in the default attributes section in your environment:

Files

"openstack": {
    "image": {
        "api": {
            "default_store": "file"
        },
        "upload_images": [
            "cirros"
        ],
        "image_upload": true
    }
}

Swift

"openstack": {
    "image": {
        "api": {
            "default_store": "swift"
        },
        "upload_images": [
            "cirros"
        ],
        "image_upload": true
    }
}
