commit 6f8d14aa1997b5a4b79fbe10129fe898bfe36161 Author: Andy McCrae Date: Mon Jul 20 16:07:23 2015 +0100 Add swift-sync role and environment Add the swift-remote host group and environment file. Add an os_swift_sync role which will sync the swift ring and ssh keys for swift hosts (remote and not-remote). Which has the following: * Moves the key and ring tasks out of os_swift role to os_swift_sync. * This adds the use of the "-r" flag that was added to the swift_rings.py and swift_rings_check.py. * Adds a ring.builder vs contents file consistency check. * Adjusts the rsync process to use the built-in synchronize module * Ensure services have started post ring/ssh key sync. Adds environment file and sample configuration file for swift-remote hosts (conf.d). Move appropriate default vars to the os_swift_sync role, and remove them from the os_swift role. Rename the "os-swift-install.yml" playbook to "os-swift-setup.yml" as this handles only the setup, and add a playbook to for both os-swift-sync.yml and an overarching playbook (os-swift-install.yml) that will call both the os-swift-sync.yml and os-swift-setup.yml playbooks. This means the funcitonality of "os-swift-install.yml" remains unchanged. Adjust the run-playbooks.sh so that it calls the new overarching swift playbook.
