This change adds support for configuring Apt repositories on Ubuntu hosts during host configuration. Repositories are configured in a single file (/etc/apt/sources.list.d/kayobe.sources), using the modern deb822 format [1]. This format is more flexible and readable than the original single-line format, particularly if multiple options are used. Using a single file allows us to more easily keep the set of repositories in sync, since Ansible doesn't make it easy to clean things up. Support is added for marking repositories as signed by a particular GPG key. This approach is now preferred over the deprecated [2] apt-key tool, which resulted in a set of globally trusted keys. It is also possible to disable the repositories in /etc/apt/sources.list via apt_disable_sources_list. This allows for replacing the standard repositories with a local mirror. CI tests and documentation are provided.

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.
Features
- Heavily automated using Ansible
- kayobe Command Line Interface (CLI) for cloud operators
- Deployment of a seed VM used to manage the OpenStack control plane
- Configuration of physical network infrastructure
- Discovery, introspection and provisioning of control plane hardware using OpenStack bifrost
- Deployment of an OpenStack control plane using OpenStack kolla-ansible
- Discovery, introspection and provisioning of bare metal compute hosts using OpenStack ironic and ironic inspector
- Virtualised compute using OpenStack nova
- Containerised workloads on bare metal using OpenStack magnum
- Big data on bare metal using OpenStack sahara
- Control plane and workload monitoring and log aggregation using OpenStack monasca
