We might have to change this in deployment/cephadm/ceph-rgw.yaml :
~~~
      keystone_resources:
        swift:
          endpoints:
            public: {get_param: [EndpointMap, CephRgwPublic, uri]}
            internal: {get_param: [EndpointMap, CephRgwInternal, uri]}
            admin: {get_param: [EndpointMap, CephRgwAdmin, uri]}
          users:
            swift:
              password: {get_param: SwiftPassword}
              roles:
                - admin
                - member
          region: {get_param: KeystoneRegion}
          service: 'object-store'
          roles:
            - member
            - ResellerAdmin
            - swiftoperator
