-:warning: **WARNING** :warning: This feature is community supported and has not been tested by Red Hat. Visit [docs.openshift.com](https://docs.openshift.com) for [OpenShift Enterprise](https://docs.openshift.com/enterprise/latest/install_config/install/index.html) or [OpenShift Origin](https://docs.openshift.org/latest/install_config/install/index.html) supported installation docs.

-Requirements
-------------
-- ansible (the latest 1.9 release is preferred, but any version greater than 1.9.1 should be sufficient).
-- vagrant (tested against version 1.7.2)
-- vagrant-hostmanager plugin (tested against version 1.5.0)
-- vagrant-libvirt (tested against version 0.0.26)
-  - Only required if using libvirt instead of virtualbox
-
-For ``enterprise`` deployment types the base RHEL box has to be added to Vagrant:
-
-1. Download the RHEL7 vagrant image (libvirt or virtualbox) available from the [Red Hat Container Development Kit downloads in the customer portal](https://access.redhat.com/downloads/content/293/ver=1/rhel---7/1.0.1/x86_64/product-downloads)
-
-2. Install it into vagrant
-
-   ``$ vagrant box add --name rhel-7 /path/to/rhel-server-libvirt-7.1-3.x86_64.box``
-
-3. (optional, recommended) Increase the disk size of the image to 20GB - This is a two step process. (these instructions are specific to libvirt)
-
-    Resize the actual qcow2 image:
-
-	``$ qemu-img resize ~/.vagrant.d/boxes/rhel-7/0/libvirt/box.img 20GB``
-
-    Edit `~/.vagrant.d/boxes/rhel-7/0/libvirt/metadata.json` to reflect the new size.  A corrected metadata.json looks like this:
-
-	``{"provider": "libvirt", "format": "qcow2", "virtual_size": 20}``
-
-Usage
------
-```
-vagrant up --no-provision
-vagrant provision
-```
-
-Using libvirt:
-```
-vagrant up --provider=libvirt --no-provision
-vagrant provision
-```
-
-Environment Variables
----------------------
-The following environment variables can be overridden:
-- ``OPENSHIFT_DEPLOYMENT_TYPE`` (defaults to origin, choices: origin, openshift-enterprise)
-- ``OPENSHIFT_NUM_NODES`` (the number of nodes to create, defaults to 2)
-
-Note that if ``OPENSHIFT_DEPLOYMENT_TYPE`` is ``enterprise`` you should also specify environment variables related to ``subscription-manager`` which are used by the ``rhel_subscribe`` role:
-
-- ``rhel_subscription_user``: rhsm user
-- ``rhel_subscription_pass``: rhsm password
-- (optional) ``rhel_subscription_pool``: poolID to attach a specific subscription besides what auto-attach detects
