+### ceph\_radosgw
+
+The ceph\_radosgw LWRP provides an easy way to setup customized radosgw servers. The LWRP itself just adds a node attribute, and then the radosgw recipe does all the setup. Due to the way Chef processes the runlist, this resource has to be explicitly converged before compiling the radosgw recipe. Any recipe that calls this LWRP has to say `.run_action(:add)` after the do..end block. Alternatively, the node attributes can be set with a wrapper cookbook.
