1. How Rackspace Is Deploying OpenStack with Ansible Walter Bentley, RPC Solutions Architect Twitter: @djstayflypro LinkedIn: http://goo.gl/r2p21i Github: wbentley15 Blog: hitchnyc.com
2. 2 I started my 17-year IT career as an MS .ASP developer and transitioned into supporting web-based applications. The bulk of my time was spent providing production support as an on-call engineer. Who Am I?
3. 3 How Did We Get Here? Hybrid Stable & Scalable Automation Flexible •  In early 2014, Rackspace embarked on the journey of developing a RPC version to move from the OpenStack release of Havana onto Icehouse! •  Looking to implement improvements gained from the many lessons learned! •  New reference architecture had to deliver these 4 core principles:"

5. 5 Rackspace Private Cloud v9.0 – built on OpenStack Reference Architecture Artifact
6. 6 www.rackspace.com Why Ansible? •  Clarity and ease of use! •  Creating playbooks is highly accessible for developers! •  Other groups in Rackspace already using Ansible, and Rackspace has a good relationship with them! •  Existing Ansible modules for OpenStack! •  Ease of use in configuring hosts and containers! •  Only SSH and Python required on the target device, no clients/agents! •  Components and configurations can be upgraded or modified in isolation or combination"
7. 7 www.rackspace.com What I Love About Ansible •  Open Source!!! •  Ansible’s goal first and foremost is simplicity and maximum ease of use •  Code is written in Python •  Playbooks are written in the YAML format •  Clearly defined best practices
8. Rackspace Private Cloud (RPC) v9.0 Under the Covers
9. 9 www.rackspace.com Rackspace Private Cloud v9.0 Under the Covers To deploy the OpenStack Private Cloud, it was broken down into three main playbooks:! •  ansible-playbook -e @/etc/rpc_deploy/user_variables.yml playbooks/setup/host-setup.yml! •  ansible-playbook -e @/etc/rpc_deploy/user_variables.yml playbooks/infrastructure/haproxy-install.yml (optional)! •  ansible-playbook -e @/etc/rpc_deploy/user_variables.yml playbooks/infrastructure/infrastructure- setup.yml! •  ansible-playbook -e @/etc/rpc_deploy/user_variables.yml playbooks/openstack/openstack-setup.yml
 ! All playbooks are dependent on two configuration files:! •  rpc_user_config.yml" •  user_variables.yml"
10. 10 www.rackspace.com Rackspace Private Cloud v9.0 Before You Get in Bed For a person like me…! If you plan to do it once…!
11. 11 www.rackspace.com Why not create some roles and playbooks to automate all those pre-configurations!
12. 12 www.rackspace.com Rackspace Private Cloud v9.0 How Ansible Solved My Problem Decided to build some playbooks to handle all the pre-implementation work! •  Deploy locally; using Vagrant, VirtualBox and of course…Ansible! •  git clone --recursive https://github.com/wbentley15/vagrant-rpcv901_deploy.git" •  git clone --recursive https://github.com/wbentley15/vagrant-rpcv901.git" •  Deploy on Rackspace Public Cloud; solely using Ansible!
13. 13 www.rackspace.com OpenStack Community Adoption In the end of November, the community voted to accept our playbooks as a Stackforge repository, making them the basis of Ansible support for OpenStack going forward! •  https://review.openstack.org/#/c/132703 •  Community Page: https://review.openstack.org/#/admin/projects/stackforge/os-ansible-deployment •  Issues: https://bugs.launchpad.net/~openstack-ansible •  IRC on Freenode: #openstack-ansible •  Code Location: https://github.com/stackforge/os-ansible-deployment This means a lot to Rackspace and opens up the door for community contribution!
