- # This is an example of an OpenShift-Ansible host inventory for a cluster
- # with natively hosted, containerized GlusterFS storage for both general
- # application use and a natively hosted Docker registry. It will also create a
- # StorageClass for the general storage.
- #
- # This inventory may be used with the deploy_cluster.yml playbook to deploy a new
- # cluster with GlusterFS storage.
- #
- # This inventory may also be used with openshift-glusterfs/config.yml to
- # deploy GlusterFS storage on an existing cluster. With this playbook, the
- # registry backend volume will be created but the administrator must then
- # either deploy a hosted registry or change an existing hosted registry to use
- # that volume.
- #
- # There are additional configuration parameters that can be specified to
- # control the deployment and state of a GlusterFS cluster. Please see the
- # documentation in playbooks/openshift-glusterfs/README.md and
- # roles/openshift_storage_glusterfs/README.md for additional details.
