+# OpenStack Provisioning
+
+This directory contains [Ansible][ansible] playbooks and roles to create
+OpenStack resources (servers, networking, volumes, security groups,
+etc.). The result is an environment ready for OpenShift installation
+via [openshift-ansible].
+
+We provide everything necessary to be able to install OpenShift on
+OpenStack (including the DNS and load balancer servers when
+necessary). In addition, we work on providing integration with the
+OpenStack-native services (storage, lbaas, baremetal as a service,
+dns, etc.).
+
+
+## OpenStack Requirements
+
+Before you start the installation, you need to have an OpenStack
+environment to connect to. You can use a public cloud or an OpenStack
+within your organisation. It is also possible to
+use [Devstack][devstack] or [TripleO][tripleo]. In the case of
+TripleO, we will be running on top of the **overcloud**.
+
+The OpenStack release must be Newton (for Red Hat OpenStack this is
+version 10) or newer. It must also satisfy these requirements:
+
+* Heat (Orchestration) must be available
+* The deployment image (CentOS 7 or RHEL 7) must be loaded
+* The deployment flavor must be available to your user
+  - `m1.medium` / 4GB RAM + 40GB disk should be enough for testing
+  - look at
+    the [Minimum Hardware Requirements page][hardware-requirements]
+    for production
+* The keypair for SSH must be available in openstack
+* `keystonerc` file that lets you talk to the openstack services
+   * NOTE: only Keystone V2 is currently supported
+
+Optional:
+* External Neutron network with a floating IP address pool
+
+
+## DNS Requirements
+
+OpenShift requires DNS to operate properly. OpenStack supports DNS-as-a-service
+in the form of the Designate project, but the playbooks here don't support it
+yet. Until we do, you will need to provide a DNS solution yourself (or in case
+you are not running Designate when we do).
+
+If your server supports nsupdate, we will use it to add the necessary records.
+
+TODO(shadower): describe how to build a sample DNS server and how to configure
+our playbooks for nsupdate.
+
+
+## Installation
+
+There are four main parts to the installation:
+
+1. [Preparing Ansible and dependencies](#1-preparing-ansible-and-dependencies)
+2. [Configuring the desired OpenStack environment and OpenShift cluster](#2-configuring-the-openstack-environment-and-openshift-cluster)
+3. [Creating the OpenStack resources (VMs, networking, etc.)](#3-creating-the-openstack-resources-vms-networking-etc)
+4. [Installing OpenShift](#4-installing-openshift)
+
+This guide is going to install [OpenShift Origin][origin]
+with [CentOS 7][centos7] images with minimal customisation.
+
+We will create the VMs for running OpenShift, in a new Neutron
+network, assign Floating IP addresses and configure DNS.
+
+The OpenShift cluster will have a single Master node that will run
+`etcd`, a single Infra node and two App nodes.
+
+You can look at
+the [Advanced Configuration page][advanced-configuration] for
+additional options.
+
+
+
+### 1. Preparing Ansible and dependencies
+
+First, you need to select where to run [Ansible][ansible] from (the
+*Ansible host*). This can be the computer you read this guide on or an
+OpenStack VM you'll create specifically for this purpose.
+
+We will use
+a
+[Docker image that has all the dependencies installed][control-host-image] to
+make things easier. If you don't want to use Docker, take a look at
+the [Ansible host dependencies][ansible-dependencies] and make sure
+they're installed.
+
+Your *Ansible host* needs to have the following:
+
+1. Docker
+2. `keystonerc` file with your OpenStack credentials
+3. SSH private key for logging in to your OpenShift nodes
+
+Assuming your private key is `~/.ssh/id_rsa` and `keystonerc` in your
+current directory:
+
+```bash
+$ sudo docker run -it -v ~/.ssh:/mnt/.ssh:Z \
+     -v $PWD/keystonerc:/root/.config/openstack/keystonerc.sh:Z \
+     redhatcop/control-host-openstack bash
+```
+
+This will create the container, add your SSH key and source your
+`keystonerc`. It should be set up for the installation.
+
+You can verify that everything is in order:
+
+
+```bash
+$ less .ssh/id_rsa
+$ ansible --version
+$ openstack image list
+```
+
+
+### 2. Configuring the OpenStack Environment and OpenShift Cluster
+
+The configuration is all done in an Ansible inventory directory. We
+will clone the [openshift-ansible][openshift-ansible] repository and set
+things up for a minimal installation.
+
+
+```
+$ git clone https://github.com/openshift/openshift-ansible
+$ cp -r openshift-ansible/playbooks/openstack/sample-inventory/ inventory
+```
+
+If you're testing multiple configurations, you can have multiple
+inventories and switch between them.
+
+#### OpenStack Configuration
+
+The OpenStack configuration is in `inventory/group_vars/all.yml`.
+
+Open the file and plug in the image, flavor and network configuration
+corresponding to your OpenStack installation.
+
+```bash
+$ vi inventory/group_vars/all.yml
+```
+
+1. Set the `openshift_openstack_keypair_name` to your OpenStack keypair name.
+   - See `openstack keypair list` to find the keypairs registered with
+   OpenShift.
+   - This must correspond to your private SSH key in `~/.ssh/id_rsa`
+2. Set the `openshift_openstack_external_network_name` to the floating IP
+   network of your openstack.
+   - See `openstack network list` for the list of networks.
+   - It's often called `public`, `external` or `ext-net`.
+3. Set the `openshift_openstack_default_image_name` to the image you want your
+   OpenShift VMs to run.
+   - See `openstack image list` for the list of available images.
+4. Set the `openshift_openstack_default_flavor` to the flavor you want your
+   OpenShift VMs to use.
+   - See `openstack flavor list` for the list of available flavors.
+5. Set the `openshift_openstack_dns_nameservers` to the list of the IP addresses
+   of the DNS servers used for the **private** address resolution.
+
+**NOTE ON DNS**: at minimum, the OpenShift nodes need to be able to access each
+other by their hostname.  OpenStack doesn't provide this by default, so you
+need to provide a DNS server. Put the address of that DNS server in
+`openshift_openstack_dns_nameservers` variable.
+
+
+
+
+#### OpenShift configuration
+
+The OpenShift configuration is in `inventory/group_vars/OSEv3.yml`.
+
+The default options will mostly work, but unless you used the large
+flavors for a production-ready environment, openshift-ansible's
+hardware check will fail.
+
+Let's disable those checks by putting this in
+`inventory/group_vars/OSEv3.yml`:
+
+```yaml
+openshift_disable_check: disk_availability,memory_availability
+```
+
+**NOTE**: The default authentication method will allow **any username
+and password** in! If you're running this in a public place, you need
+to set up access control.
+
+Feel free to look at
+the [Sample OpenShift Inventory][sample-openshift-inventory] and
+the [advanced configuration][advanced-configuration].
+
+
+### 3. Creating the OpenStack resources (VMs, networking, etc.)
+
+We provide an `ansible.cfg` file which has some useful defaults -- you should
+copy it to the directory you're going to run `ansible-playbook` from.
+
+```bash
+$ cp openshift-ansible/ansible.cfg ansible.cfg
+```
+
+Then run the provisioning playbook -- this will create the OpenStack
+resources:
+
+```bash
+$ ansible-playbook --user openshift -i inventory openshift-ansible/playbooks/openstack/openshift-cluster/provision.yaml
+```
+
+If you're using multiple inventories, make sure you pass the path to
+the right one to `-i`.
+
+If your SSH private key is not in `~/.ssh/id_rsa` use the `--private-key`
+option to specify the correct path.
+
+
+### 4. Installing OpenShift
+
+Run the `byo/config.yml` playbook on top of the OpenStack nodes we have
+prepared.
+
+```bash
+$ ansible-playbook -i inventory openshift-ansible/playbooks/byo/config.yml
+```
+
+
+### Next Steps
+
+And that's it! You should have a small but functional OpenShift
+cluster now.
+
+Take a look at [how to access the cluster][accessing-openshift]
+and [how to remove it][uninstall-openshift] as well as the more
+advanced configuration:
+
+* [Accessing the OpenShift cluster][accessing-openshift]
+* [Removing the OpenShift cluster][uninstall-openshift]
+* Set Up Authentication (TODO)
+* [Multiple Masters with a load balancer][loadbalancer]
+* [External Dns][external-dns]
+* Multiple Clusters (TODO)
+* [Cinder Registry][cinder-registry]
+* [Bastion Node][bastion]
