+## Requirements
+* ansible
+ * Tested using ansible 1.9.1 and 1.9.2
+ * There is currently a known issue with ansible-1.9.0, you can downgrade to 1.8.4 on Fedora by installing one of the builds from Koji: http://koji.fedoraproject.org/koji/packageinfo?packageID=13842
+ * Available in Fedora channels
+ * Available for EL with EPEL and Optional channel
+* One or more RHEL 7.1 VMs
+* Either ssh key based auth for the root user or ssh key based auth for a user
+ with sudo access (no password)
+* A checkout of atomic-enterprise-ansible from https://github.com/projectatomic/atomic-enterprise-ansible/
+
+ ```sh
+ git clone https://github.com/projectatomic/atomic-enterprise-ansible.git
+ cd atomic-enterprise-ansible
+ ```
+
+## Caveats
+This ansible repo is currently under heavy revision for providing OSE support;
+the following items are highly likely to change before the OSE support is
+merged into the upstream repo:
+ * the current git branch for testing
+ * how the inventory file should be configured
+ * variables that need to be set
+ * bootstrapping steps
+ * other configuration steps
+
+## Known Issues
+* Host subscriptions are not configurable yet, the hosts need to be
+ pre-registered with subscription-manager or have the RHEL base repo
+ pre-configured. If using subscription-manager the following commands will
+ disable all but the rhel-7-server rhel-7-server-extras and
+ rhel-server7-ose-beta repos:
+```sh
+subscription-manager repos --disable="*"
+subscription-manager repos \
+--enable="rhel-7-server-rpms" \
+--enable="rhel-7-server-extras-rpms" \
+--enable="rhel-7-server-ose-3.0-rpms"
+```
+* Configuration of router is not automated yet
+* Configuration of docker-registry is not automated yet
+
+## Configuring the host inventory
+[Ansible docs](http://docs.ansible.com/intro_inventory.html)
+
+Example inventory file for configuring one master and two nodes for the test
+environment. This can be configured in the default inventory file
+(/etc/ansible/hosts), or using a custom file and passing the --inventory
+option to ansible-playbook.
+
+/etc/ansible/hosts:
+```ini
+# This is an example of a bring your own (byo) host inventory
+
+# Create an OSEv3 group that contains the masters and nodes groups
+[OSEv3:children]
+masters
+nodes
+
+# Set variables common for all OSEv3 hosts
+[OSEv3:vars]
+# SSH user, this user should allow ssh based auth without requiring a password
+ansible_ssh_user=root
+
+# If ansible_ssh_user is not root, ansible_sudo must be set to true
+#ansible_sudo=true
+
+# To deploy origin, change deployment_type to origin
+deployment_type=enterprise
+
+# Pre-release registry URL
+oreg_url=docker-buildvm-rhose.usersys.redhat.com:5000/openshift3/ose-${component}:${version}
+
+# Pre-release additional repo
+openshift_additional_repos=[{'id': 'ose-devel', 'name': 'ose-devel',
+'baseurl':
+'http://buildvm-devops.usersys.redhat.com/puddle/build/OpenShiftEnterprise/3.0/latest/RH7-RHOSE-3.0/$basearch/os',
+'enabled': 1, 'gpgcheck': 0}]
+
+# Origin copr repo
+#openshift_additional_repos=[{'id': 'openshift-origin-copr', 'name':
+'OpenShift Origin COPR', 'baseurl':
+'https://copr-be.cloud.fedoraproject.org/results/maxamillion/origin-next/epel-7-$basearch/',
+'enabled': 1, 'gpgcheck': 1, gpgkey:
+'https://copr-be.cloud.fedoraproject.org/results/maxamillion/origin-next/pubkey.gpg'}]
+
+# host group for masters
+[masters]
+ose3-master.example.com
+
+# host group for nodes
+[nodes]
+ose3-node[1:2].example.com
+```
+
+The hostnames above should resolve both from the hosts themselves and
+the host where ansible is running (if different).
+
+## Running the ansible playbooks
+From the atomic-enterprise-ansible checkout run:
+```sh
+ansible-playbook playbooks/byo/config.yml
+```
+**Note:** this assumes that the host inventory is /etc/ansible/hosts, if using a different
+inventory file use the -i option for ansible-playbook.
+
+## Post-ansible steps
+#### Create the default router
+On the master host:
+```sh
+oadm router --create=true \
+ --credentials=/etc/openshift/master/openshift-router.kubeconfig \
+ --images='docker-buildvm-rhose.usersys.redhat.com:5000/openshift3/ose-${component}:${version}'
+```
+
+#### Create the default docker-registry
+On the master host:
+```sh
+oadm registry --create=true \
+ --credentials=/etc/openshift/master/openshift-registry.kubeconfig \
+ --images='docker-buildvm-rhose.usersys.redhat.com:5000/openshift3/ose-${component}:${version}' \
+ --mount-host=/var/lib/openshift/docker-registry
+```
+
+## Overriding detected ip addresses and hostnames
+Some deployments will require that the user override the detected hostnames
+and ip addresses for the hosts. To see what the default values will be you can
+run the openshift_facts playbook:
+```sh
+ansible-playbook playbooks/byo/openshift_facts.yml
+```
+The output will be similar to:
+```
+ok: [10.3.9.45] => {
+ "result": {
+ "ansible_facts": {
+ "openshift": {
+ "common": {

+ }
+ }
+ },
+ "changed": false,
+ "invocation": {
+ "module_args": "",
+ "module_name": "openshift_facts"
+ }
+ }
+}
+```
+Now, we want to verify the detected common settings to verify that they are
+what we expect them to be (if not, we can override them).
+
+* hostname
+ * Should resolve to the internal ip from the instances themselves.
+ * openshift_hostname will override.
+* ip
+ * Should be the internal ip of the instance.
+ * openshift_ip will override.
+* public hostname
+ * Should resolve to the external ip from hosts outside of the cloud
+ * provider openshift_public_hostname will override.
+* public_ip
+ * Should be the externally accessible ip associated with the instance
+ * openshift_public_ip will override
+* use_openshift_sdn
+ * Should be true unless the cloud is GCE.
+ * openshift_use_openshift_sdn overrides
+
+To override the the defaults, you can set the variables in your inventory:
+```
+...snip...
+[masters]
+ose3-master.example.com openshift_ip=1.1.1.1 openshift_hostname=ose3-master.example.com openshift_public_ip=2.2.2.2 openshift_public_hostname=ose3-master.public.example.com
+...snip...
