# This is an example of an OpenShift-Ansible host inventory for a cluster # with natively hosted, containerized GlusterFS storage. # # This inventory may be used with the deploy_cluster.yml playbook to deploy a new # cluster with GlusterFS storage, which will use that storage to create a # volume that will provide backend storage for a hosted Docker registry. # # 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.
