- 1. TripleO: OpenStack on OpenStack Chris Jones IRC: Ng (Freenode) Twitter: @cmsj Email: cmsj@tenshu.net © Copyright 2013 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice.
- 2. What is TripleO (OpenStack On OpenStack)? ➡ Using OpenStack to deploy OpenStack on real hardware © Copyright 2013 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice.
- 3. Why? ➡ Lots of existing tools/methods for deploying OpenStack ➡ Few prioritise deployment speed ➡ Few leverage OpenStack’s inherent ability to provision machine resources ➡ Standard OpenStack APIs for infrastructure is awesome © Copyright 2013 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice.
- 4. What is TripleO made of? ➡ OpenStack components: ➡ nova-baremetal ➡ neutron ➡ heat ➡ Original components: ➡ diskimage-builder ➡ configuration management tools © Copyright 2013 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice.
- 5. How does a TripleO deployment work? ➡ Heat drives “seed” VM to deploy an "undercloud" image to bare metal ➡ nova-baremetal switches on a suitable machine via IPMI ➡ machine netboots into ramdisk to write image to disk, then reboots ➡ config management tools configure machine and start service daemons ➡ repeat until “undercloud” is functional ➡ Heat drives “undercloud” to repeat entire process until “overcloud” is functional © Copyright 2013 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice.
- 6. How do changes/upgrades work? ➡ Configuration changes can be applied by config management ➡ Beware entropy! ➡ Image upgrades are driven by “nova rebuild” and the deployment ramdisk ➡ (Ask me afterwards if you want to know how data persists the rebuild) © Copyright 2013 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice.
- 7. Why use images for deployment? ➡ Speed (dd vs OS installer) ➡ Also applies to rollbacks ➡ Reproducibility (e.g. package version skew) © Copyright 2013 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice.
- 8. Why is speed so important? ➡ Continuous Delivery gives you control and flexibility ➡ Why wait for an OpenStack release if trunk passes tests? ➡ Quicker bug fixes ➡ Quicker feature addition © Copyright 2013 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice.
- 9. How can I try it out? ➡ “tripleo-incubator” git repo on git.openstack.org ➡ devtest.sh ➡ Creates 4 VMs to emulate real hardware ➡ Deploys full (but non-HA) seed/undercloud/overcloud environment © Copyright 2013 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice.
