For isolation and ease of maintenance, you can install OpenStack components into Linux containers (LXC). +Why choose OpenStack-Ansible? +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +* Supports the major Linux distributions Ubuntu, CentOS (WIP) and OpenSUSE + (WIP). +* Supports the major CPU architectures x86, ppc64, s390x (WIP). +* Offers automation for upgrades between major OpenStack releases. +* Uses OpenStack defaults for each of the project roles, and provides + extra wiring and optimised configuration when combining projects + together. +* Does not implement its own DSL, and uses wherever possible Ansible + directly. All the experience acquired using Ansible can be used in + openstack-ansible, and the other way around. +* You like to use reliable, proven technology. We try to run OpenStack + with a minimum amount of packages that are not provided by distributions + or the OpenStack community. Less dependencies and distribution tested + software make the project more reliable. +* You want to be able to select how to deploy on your hardware: deploy + partially on metal, fully on metal, or fully in machine containers. + +When **not** to choose OpenStack-Ansible? +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +* If your company is already invested with other configuration management + systems, Puppet or Chef, and does not want to use Ansible we recommend + re-using your knowledge and experimenting with a different + OpenStack deployment project. +* You want to deploy OpenStack with 100% application containers. + We currently support machine containers, with lxc and we will support + *systemd-nspawn* in the future (WIP). If you want to go 100% Docker, + there are other projects in the OpenStack community that can + help you. + Ansible ~~~~~~~
