Deploy and Use OpenStack with Ansible

#OpenStack #Anisble #Kolla
Ansible 是個讓自動化簡單易用的開放原始碼的計畫 --- 它目前是最多人使用用來部署跟設定OpenStack環境的工具。現在，就連OpenStack-infra team 都使用它來自動化OpenStack 的CI 測試。想要知道如何使用Ansible 部署跟應用你的OpenStack 雲嗎？這講題就是你的最佳選擇。如果你知道 Ansible 跟 OpenStack 卻不知道如何開始自動化你的 IT ？ 這講題也是你的最佳選擇。
來這個講題你能：

- 了解 Ansible 跟它與 OpenStack 的關係。
- 如何使用 Ansible 快速、輕鬆部署一個 OpenStack 環境。
- 如何使用 Ansible 中的 OpenStack Modules 操作 OpenStack 雲。

14. OpenStack-Ansible https://docs.openstack.org/developer/openstack-ansible/
15. • Ansible Playbooks for deploying OpenStack • Supports installation of most of the OpenStack Projects • Deploys OpenStack on LXC (or baremetal) • Deploys OpenStack from Source • Scalable while also being simple to operate, upgrade, and grow • Ceph Ansible integration ANSIBLE OPENSTACK ANSIBLE KOLLA ANSIBLE OPENSTACK MODULES DEMO
16. • Need to manaul install Operating System • Required to setup network bridges • At least 4 nodes minimum (infra, compute, storage, log) ANSIBLE OPENSTACK ANSIBLE KOLLA ANSIBLE OPENSTACK MODULES DEMO Drawbacks:
17. • MariaDB with Galera • Memcached • Repository • Load balancer • Log aggregation host • Unbound DNS container ANSIBLE OPENSTACK ANSIBLE KOLLA ANSIBLE OPENSTACK MODULES DEMO
18. • Bare Metal (ironic) • Block Storage (cinder) • Compute (nova) • Container Infrastructure Management (magnum) • Dashboard (horizon) • Data Processing (sahara) • Identity (keystone) • Image (glance) • Networking (neutron) • Object Storage (swift) • Orchestration (heat) • Telemetry (aodh, ceilometer, gnocchi) ANSIBLE OPENSTACK ANSIBLE KOLLA ANSIBLE OPENSTACK MODULES DEMO

30. • Ansible Modules for managing OpenStack Clouds • Supports Nova, Keystone, Glance, Neutron, Ironic, Cinder, Swift • Will do almost the same as a HEAT template • Easy to manage full stack automation • Hide difference in datacenter architecture DEMO ANSIBLE OPENSTACK ANSIBLE KOLLA ANSIBLE OPENSTACK MODULES
31. • Keystone: user, groups, roles, projects • Nova: servers, keypairs, security groups, flavors • Neutron: network, ports, subnet, routers, floating IPs • Ironic: nodes, introspection • Swift Objects • Cinder Volume • Glance Image DEMO ANSIBLE OPENSTACK ANSIBLE KOLLA ANSIBLE OPENSTACK MODULES
