+# Installing OSEv3 from dev puddles using ansible

+* [Requirements](#requirements)
+* [Caveats](#caveats)
+* [Known Issues](#known-issues)
+* [Configuring the host inventory](#configuring-the-host-inventory)
+* [Creating the default variables for the hosts and host groups](#creating-the-default-variables-for-the-hosts-and-host-groups)

+* [Post-ansible steps](#post-ansible-steps)
+
+## Requirements
+* ansible
+  * Tested using ansible-1.8.2-1.fc20.noarch, but should work with version 1.8+
+  * Available in Fedora channels
+  * Available for EL with EPEL and Optional channel
+* One or more RHEL 7.1 VMs
+* ssh key based auth for the root user needs to be pre-configured from the host
+  running ansible to the remote hosts
+* A checkout of openshift-ansible from https://github.com/openshift/openshift-ansible/
+  
+  ```sh
+  git clone https://github.com/openshift/openshift-ansible.git
+  cd openshift-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-server-7-ose-beta-rpms"
+```
+* Configuration of router is not automated yet
+* Configuration of docker-registry is not automated yet
+* End-to-end testing has not been completed yet using this module
+* root user is used for all ansible actions; eventually we will support using
+  a non-root user with sudo.
+
+## 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
+
+# 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).
+
+## Creating the default variables for the hosts and host groups
+[Ansible docs](http://docs.ansible.com/intro_inventory.html#id9)
+
+#### Group vars for all hosts
+/etc/ansible/group_vars/all:
+```yaml
+---
+# Assume that we want to use the root as the ssh user for all hosts
+ansible_ssh_user: root
+
+# Default debug level for all OpenShift hosts
+openshift_debug_level: 4
+
+# Set the OpenShift deployment type for all hosts
+openshift_deployment_type: enterprise
+
+# Override the default registry for development
+openshift_registry_url: docker-buildvm-rhose.usersys.redhat.com:5000/openshift3_beta/ose-${component}:${version}
+
+# To use the latest OpenShift Enterprise Errata puddle:
+#openshift_additional_repos:
+#- id: ose-devel
+#  name: ose-devel
+#  baseurl: http://buildvm-devops.usersys.redhat.com/puddle/build/OpenShiftEnterpriseErrata/3.0/latest/RH7-RHOSE-3.0/$basearch/os
+#  enabled: 1
+#  gpgcheck: 0
+# To use the latest OpenShift Enterprise Whitelist puddle:
+openshift_additional_repos:
+- id: ose-devel
+  name: ose-devel
+  baseurl: http://buildvm-devops.usersys.redhat.com/puddle/build/OpenShiftEnterprise/3.0/latest/RH7-RHOSE-3.0/$basearch/os
+  enabled: 1
+  gpgcheck: 0
+
+```
+
+## Running the ansible playbooks
+From the openshift-ansible checkout run:
+```sh
+ansible-playbook playbooks/byo/config.yml
+```
+**Note:** this assumes that the host inventory is /etc/ansible/hosts and the
+group_vars are defined in /etc/ansible/group_vars, if using a different
+inventory file (and a group_vars directory that is in the same directory as
+the directory as the inventory) use the -i option for ansible-playbook.
+
+## Post-ansible steps
+#### Create the default router
+On the master host:
+```sh
+systemctl restart openshift-sdn-master
+openshift ex router --create=true \
+  --credentials=/var/lib/openshift/openshift.local.certificates/openshift-client/.kubeconfig \
+  --images='docker-buildvm-rhose.usersys.redhat.com:5000/openshift3_beta/ose-${component}:${version}'
+```
+
+#### Create the default docker-registry
+On the master host:
+```sh
+openshift ex registry --create=true \
+  --credentials=/var/lib/openshift/openshift.local.certificates/openshift-client/.kubeconfig \
+  --images='docker-buildvm-rhose.usersys.redhat.com:5000/openshift3_beta/ose-${component}:${version}' \
+  --mount-host=/var/lib/openshift/docker-registry
+```
