Using radosgw as a drop-in replacement for Swift¶
OpenStack-Ansible gives you the option of deploying radosgw as a drop-in replacement for native OpenStack Swift.
In particular, the ceph-rgw-install.yml playbook (which includes
ceph-rgw-keystone-setup.yml) will deploy radosgw to any
ceph-rgw hosts, and create a corresponding Keystone
object-store service catalog entry. The service endpoints do
contain the AUTH_%(tenant_id)s prefix just like in native Swift,
so public read ACLs and temp URLs will work just like they do in
Swift.
By default, OSA enables only the Swift API in radosgw.
Adding S3 API support¶
You may want to enable the default radosgw S3 API, in addition to the
Swift API. In order to do so, you need to override the
ceph_conf_overrides_rgw variable in user_variables.yml. Below
is an example configuration snippet:
ceph_conf_overrides_rgw:
"client.rgw.{{ hostvars[inventory_hostname]['ansible_hostname'] }}":
# OpenStack integration with Keystone
rgw_keystone_url: "{{ keystone_service_adminuri }}"
rgw_keystone_api_version: 3
rgw_keystone_admin_user: "{{ radosgw_admin_user }}"
rgw_keystone_admin_password: "{{ radosgw_admin_password }}"
rgw_keystone_admin_tenant: "{{ radosgw_admin_tenant }}"
rgw_keystone_admin_domain: default
rgw_keystone_accepted_roles: 'member, _member_, admin, swiftoperator'
rgw_keystone_implicit_tenants: 'true'
rgw_swift_account_in_url: true
rgw_swift_versioning_enabled: 'true'
# Add S3 support, in addition to Swift
rgw_enable_apis: 'swift, s3'
rgw_s3_auth_use_keystone: 'true'
You may also want to add the rgw_dns_name option if you want to
enable bucket hostnames with the S3 API.
