Configuring the Image service
In an all-in-one deployment with a single infrastructure node, the Image service uses the local file system on the target host to store images. When deploying production clouds we recommend backing Glance with a swift backend or some form or another of shared storage.
The following procedure describes how to modify the
/etc/openstack_deploy/user_variables.yml
file to enable
Cloud Files usage.
Change the default store to use Object Storage (swift), the underlying architecture of Cloud Files:
glance_default_store: swift
Set the appropriate authentication URL:
glance_swift_store_auth_address: https://127.0.0.1/v2.0
Set the swift account credentials:
# Replace this capitalized variables with actual data. glance_swift_store_user: GLANCE_SWIFT_TENANT:GLANCE_SWIFT_USER glance_swift_store_key: SWIFT_PASSWORD_OR_KEY
Change the ``glance_swift_store_endpoint_type`` from the default ``internalURL`` settings to ``publicURL`` if needed.
glance_swift_store_endpoint_type: publicURL
Define the store name:
glance_swift_store_container: STORE_NAME
Replace ``STORE_NAME`` with the container name in swift to be used for storing images. If the container doesn't exist, it will be automatically created.
Define the store region:
glance_swift_store_region: STORE_REGION
Replace ``STORE_REGION`` if needed.
(Optional) Set the paste deploy flavor:
glance_flavor: GLANCE_FLAVOR
By default, the Image service uses caching and authenticates with the Identity service. The default maximum size of the image cache is 10 GB. The default Image service container size is 12 GB. In some configurations, the Image service might attempt to cache an image which exceeds the available disk space. If necessary, you can disable caching. For example, to use Identity without caching, replace ``GLANCE_FLAVOR`` with
keystone
:glance_flavor: keystone
Or, to disable both authentication and caching, set ``GLANCE_FLAVOR`` to no value:
glance_flavor:
This option is set by default to use authentication and cache management in the
playbooks/roles/os_glance/defaults/main.yml
file. To override the default behavior, setglance_flavor
to a different value in/etc/openstack_deploy/user_variables.yml
.The possible values for ``GLANCE_FLAVOR`` are:
- (Nothing)
caching
cachemanagement
keystone
keystone+caching
keystone+cachemanagement
(default)trusted-auth
trusted-auth+cachemanagement
