Deployment of containerised OpenStack to bare metal using kolla and bifrost

The IPA ramdisk and kernel images may be built or downloaded via a URL. If the latter option is used, any images previously downloaded to $KOLLA_CONFIG_PATH/config/ironic/ironic-agent.* would previously not be updated if the image contents change. This change introduces variables for setting a URL to a file containing checksums for the images. The algorithm used to compute the checksum is also configurable (default sha256). This allows us to ensure we are using the correct version of the image, while avoiding an expensive few hundred megabyte image download just to check. If a checksum is not specified, the image will be downloaded every time to ensure that it is up to date. Change-Id: I8120518ed98d61f3652f5205ce7ec9f798ab2aa1 Story: 2001660 Task: 6693 |

Kayobe
Kayobe enables deployment of containerised OpenStack to bare metal.
Containers offer a compelling solution for isolating OpenStack services, but running the control plane on an orchestrator such as Kubernetes or Docker Swarm adds significant complexity and operational overheads.
The hosts in an OpenStack control plane must somehow be provisioned, but deploying a secondary OpenStack cloud to do this seems like overkill.
Kayobe stands on the shoulders of giants:
- OpenStack bifrost discovers and provisions the cloud
- OpenStack kolla builds container images for OpenStack services
- OpenStack kolla-ansible delivers painless deployment and upgrade of containerised OpenStack services
To this solid base, kayobe adds:
- Configuration of cloud host OS & flexible networking
- Management of physical network devices
- A friendly openstack-like CLI
All this and more, automated from top to bottom using Ansible.
