+# OpenShift GlusterFS Playbooks
+
+These playbooks are intended to enable the use of GlusterFS volumes by pods in
+OpenShift. While they try to provide a sane set of defaults they do cover a
+variety of scenarios and configurations, so read carefully. :)
+
+## Playbook: config.yml
+
+This is the main playbook that integrates GlusterFS into a new or existing
+OpenShift cluster. It will also, if specified, configure a hosted Docker
+registry with GlusterFS backend storage.
+
+This playbook requires the `glusterfs` group to exist in the Ansible inventory
+file. The hosts in this group are the nodes of the GlusterFS cluster.
+
+ * If this is a newly configured cluster each host must have a
+   `glusterfs_devices` variable defined, each of which must be a list of block
+   storage devices intended for use only by the GlusterFS cluster. If this is
+   also an external GlusterFS cluster, you must specify
+   `openshift_storage_glusterfs_is_native=False`. If the cluster is to be
+   managed by an external heketi service you must also specify
+   `openshift_storage_glusterfs_heketi_is_native=False` and
+   `openshift_storage_glusterfs_heketi_url=<URL>` with the URL to the heketi
+   service. All these variables are specified in `[OSEv3:vars]`,
+ * If this is an existing cluster you do not need to specify a list of block
+   devices but you must specify the following variables in `[OSEv3:vars]`:
+   * `openshift_storage_glusterfs_is_missing=False`
+   * `openshift_storage_glusterfs_heketi_is_missing=False`
+
+By default, pods for a native GlusterFS cluster will be created in the
+`default` namespace. To change this, specify
+`openshift_storage_glusterfs_namespace=<other namespace>` in `[OSEv3:vars]`.
+
+To configure the deployment of a Docker registry with GlusterFS backend
+storage, specify `openshift_hosted_registry_storage_kind=glusterfs` in
+`[OSEv3:vars]`. To create a separate GlusterFS cluster for use only by the
+registry, specify a `glusterfs_registry` group that is populated as the
+`glusterfs` is with the nodes for the separate cluster. If no
+`glusterfs_registry` group is specified, the cluster defined by the `glusterfs`
+group will be used.
+
+To swap an existing hosted registry's backend storage for a GlusterFS volume,
+specify `openshift_hosted_registry_storage_glusterfs_swap=True`. To
+additoinally copy any existing contents from an existing hosted registry,
+specify `openshift_hosted_registry_storage_glusterfs_swapcopy=True`.
+
+**NOTE:** For each namespace that is to have access to GlusterFS volumes an
+Enpoints resource pointing to the GlusterFS cluster nodes and a corresponding
+Service resource must be created. If dynamic provisioning using StorageClasses
+is configure, these resources are created automatically in the namespaces that
+require them. This playbook also takes care of creating these resources in the
+namespaces used for deployment.
+
+An example of a minimal inventory file:
+```
+[OSEv3:children]
+masters
+nodes
+glusterfs
+
+[OSEv3:vars]
+ansible_ssh_user=root
+deployment_type=origin
+
+[masters]
+master
+
+[nodes]
+node0
+node1
+node2
+
+[glusterfs]
+node0 glusterfs_devices='[ "/dev/sdb" ]'
+node1 glusterfs_devices='[ "/dev/sdb", "/dev/sdc" ]'
+node2 glusterfs_devices='[ "/dev/sdd" ]'
+```
+
+## Playbook: registry.yml
+
+This playbook is intended for admins who want to deploy a hosted Docker
+registry with GlusterFS backend storage on an existing OpenShift cluster. It
+has all the same requirements and behaviors as `config.yml`.
+
+## Role: openshift_storage_glusterfs
+
+The bulk of the work is done by the `openshift_storage_glusterfs` role. This
+role can handle the deployment of GlusterFS (if it is to be hosted on the
+OpenShift cluster), the registration of GlusterFS nodes (hosted or standalone),
+and (if specified) integration as backend storage for a hosted Docker registry.
+
+See the documentation in the role's directory for further details.
+
+## Role: openshift_hosted
+
+The `openshift_hosted` role recognizes `glusterfs` as a possible storage
+backend for a hosted docker registry. It will also, if configured, handle the
+swap of an existing registry's backend storage to a GlusterFS volume.
