6. 6 www.rackspace.com What is Ansible? •  IT automation tool that can be used to: •  Configure systems •  Deploy software •  Orchestration •  eventually replace most infrastructure folks…just kidding…maybe? •  Ansible’s goal first and foremost is simplicity and maximum ease of use •  Manages systems using Secure Shell (SSH) •  No remote daemon or agent required!!! •  Code is organized into something called, playbooks, of which is written in the YAML language http://docs.ansible.com/intro.html
7. 7 www.rackspace.com Ansible Best Practices/Modules http://docs.ansible.com/playbooks_best_practices.html http://docs.ansible.com/list_of_all_modules.html
9. 9 OpenStack Ansible Deployment (OSAD) Hybrid Stable & Scalable Flexible OSAD was created to meet the following 3 principles:"
10. 10 Rackspace Private Cloud – built on OpenStack Reference Architecture Artifact
11. 11 www.rackspace.com OSAD Features and Benefits •  Ansible! •  Linux Containers (LXC)! •  Linux Bridge agent! •  Full Neutron deployment! •  Includes all PROD ready OpenStack services! •  Can be used to deploy an AIO or fully distributed multi-node HA layout!
12. 12 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!
13. OSAD Under the Covers
14. 14 www.rackspace.com OSAD Under the Covers High-level prerequisites:! •  Ubuntu 14.04 (Trusty)! •  SSH Client! •  NTP Client! •  Python 2.7 or later! •  Use of Linux networking features: Bridges and Namespaces! •  Container management: br-mgmt (Mandatory) " •  OpenStack Networking tunnel/overlay: br-vxlan (Mandatory)! •  OpenStack Networking provider: br-vlan (Mandatory)! •  Storage: br-storage (Optional)!
15. 15 www.rackspace.com OSAD Under the Covers (cont.) 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"
16. 16 www.rackspace.com Why not create some roles and playbooks to automate all those pre-configurations!
17. 17 www.rackspace.com Tips and Tricks •  Deploy using ‘Tags’ version on GitHub repo! •  Check GitHub repo for new versions and variables being introduced! •  Triple check your network setup! •  Re-deployment steps (aka the clean-up process)! •  Galera health check playbook! •  Running playbooks with ‘-l’"
