Configuring OpenStack Image Service with OpenStack Object Storage
By default, images are stored as files in the /var/lib/glance/images/ directory. However, OpenStack Image Service can be configured to use OpenStack Object Storage (Swift) for storing images, as well as other backend storage such as Ceph and GlusterFS. In this recipe, we will go through the steps required to configure OpenStack Image service (Glance) to use Object Storage service (Swift).
Getting ready
To begin with, ensure you're logged in to our OpenStack Controller host or the host that is running OpenStack Image Service.
To log in to our OpenStack Controller host that was created using Vagrant, issue the following command:
vagrant ssh controller
How to do it...
To configure OpenStack Image Service to use OpenStack Object Storage, carry out the following steps:
- We first edit the
/etc/glance/glance-api.conffile to notify Glance that we will use Swift instead of the default filesystem by editing the following line under the [DEFAULT] section:[DEFAULT] default_store = swift
- We then edit the
[glance_store]section in the same file to configure Swift:[glance_store] stores = glance.store.filesystem.Store, glance.store.http.Store, glance.store.swift.Store swift_store_auth_version = 2 swift_store_auth_address = https://192.168.100.200:5000/v2.0/ swift_store_user = service:glance swift_store_key = glance swift_store_container = glance swift_store_create_container_on_put = True swift_store_large_object_size = 5120 swift_store_large_object_chunk_size = 200 swift_enable_snet = False swift_store_auth_insecure = True - Then, we restart the two OpenStack Image Service processes to pick up the changes:
sudo restart glance-api sudo restart glance-registry
How it works...
OpenStack Image Service can be configured to use several different backend for storing images, such as Ceph, OpenStack Object Storage, and raw disk. Once Object Storage is configured as a backend, images will be uploaded to Swift instead of being stored locally.
