Kayobe allows specifying a --limit argument, which is passed through to Ansible. In some cases we wish to add an intersection with a group. This allows us to reuse playbooks for the seed, overcloud etc. For example, the lvm.yml playbook specifies a host list of seed-hypervisor:seed:overcloud. When executed as part of a kayobe overcloud host configure command, Kayobe passes a limit of overcloud. If the user specifies a --limit argument, this gets intersected with the overcloud limit: host1:&overcloud. The problem happens if the user specifies multiple parts to the host pattern in their limit using a comma, e.g. host1,host2. This results in host1,host2:&overcloud. Ansible ignores the colon, and treats this as host1 or host2:&overcloud. The solution is to use a comma to join the patterns if the user has used a comma: host1,host2,&overcloud Change-Id: Ibe42fa372c6fa0c539d2c2b0e238601286dc213d Story: 2008255 Task: 41111
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.
