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:
Bemerkung
Mentioned below overrides are default ones and will be applied to ceph-rgw group
---
ceph_conf_overrides_rgw: |-
{{
{
'client.rgw.' ~ hostvars[inventory_hostname]['ansible_facts']['hostname'] ~ '.rgw0': {
'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_project': radosgw_admin_tenant,
'rgw_keystone_admin_domain': 'default',
'rgw_keystone_accepted_roles': 'member, admin, swiftoperator',
'rgw_keystone_implicit_tenants': 'true',
'rgw_swift_account_in_url': 'true',
'rgw_swift_versioning_enabled': 'true',
'rgw_enable_apis': 'swift'
}
}
}}
# For S3 support, update/add above rows
# '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.
