+# OpenStack Provisioning
+
+This repository contains playbooks and Heat templates to provision
+OpenStack resources (servers, networking, volumes, security groups,
+etc.). The result is an environment ready for openshift-ansible.
+
+
+## Dependencies
+
+* [Ansible 2.3](https://pypi.python.org/pypi/ansible)
+* [shade](https://pypi.python.org/pypi/shade)
+
+
+## What does it do
+
+* Create Nova servers with floating IP addresses attached
+* Assigns Cinder volumes to the servers
+* Set up an `openshift` user with sudo privileges
+* Optionally attach Red Hat subscriptions
+* Set up a bind-based DNS server
+* When deploying more than one master, set up a HAproxy server
+
+
+## Set up
+
+### Copy the sample inventory
+
+    cp openshift-ansible-contrib/playbooks/provisioning/openstack/sample-inventory inventory
+
+### Copy clouds.yaml
+
+    cp openshift-ansible-contrib/playbooks/provisioning/openstack/sample-inventory/clouds.yaml clouds.yaml
+
+### Update `inventory/group_vars/all.yml`
+
+Pay special attention to the values in the first paragraph -- these
+will depend on your OpenStack environment.
+
+The `env_id` and `openstack_dns_domain` will form the DNS domain all
+your servers will be under. With the default values, this will be
+`openshift.example.com`.
+
+`openstack_nameservers` is a list of DNS servers accessible from all
+the created Nova servers. These will be serve as your DNS forwarders.
+
+`openstack_ssh_key` is a Nova keypair -- you can see your keypairs with
+`openstack keypair list`.
+
+`openstack_default_image_name` is the name of the Glance image the
+servers will use. You can
+see your images with `openstack image list`.
+
+`openstack_default_flavor` is the Nova flavor the servers will use.
+You can see your flavors with `openstack flavor list`.
+
+`openstack_external_network_name` is the name of the Neutron network
+providing external connectivity. It is often called `public`,
+`external` or `ext-net`. You can see your networks with `openstack
+network list`.
+
+The `openstack_num_masters`, `openstack_num_infra` and
+`openstack_num_nodes` values specify the number of Master, Infra and
+App nodes to create.
+
+### Update the DNS names in `inventory/hosts`
+
+The different server groups are currently grouped by the domain name,
+so if you end up using a different domain than
+`openshift.example.com`, you will need to update the `inventory/hosts`
+file.
+
+For example, if your final domain is `my.cloud.com`, you can run this
+command to fix update the `hosts` file:
+
+    sed -i 's/openshift.example.com/my.cloud.com/' inventory/hosts
+
+### Configure the OpenShift parameters
+
+Finally, you need to update the DNS entry in
+`inventory/group_vars/OSEv3.yml` (look at
+`openshift_master_default_subdomain`).
+
+In addition, this is the place where you can customise your OpenShift
+installation for example by specifying the authentication.
+
+The full list of options is available in this sample inventory:
+
+https://github.com/openshift/openshift-ansible/blob/master/inventory/byo/hosts.ose.example
+
+
+## Deployment
+
+### Run the playbook
+
+Assuming your OpenStack (Keystone) credentials are in the `keystonerc`
+file, this is how you stat the provisioning process:
+
+    . keystonerc
+    ansible-playbook -i inventory  --private-key ~/.ssh/openshift openshift-ansible-contrib/playbooks/provisioning/openstack/provision.yaml
+
+### Install OpenShift
+
+Once it succeeds, you can install openshift by running:
+
+    ansible-playbook --become --user openshift --private-key ~/.ssh/openshift -i inventory/ openshift-ansible/playbooks/byo/config.yml
+
