Running Kayobe Playbooks on Demand

In some situations it may be necessary to run an individual Kayobe playbook. Playbooks are stored in <kayobe repo>/ansible/*.yml. To run an arbitrary Kayobe playbook:

(kayobe) $ kayobe playbook run <playbook> [<playbook>]

Running Kolla-ansible Commands

To execute a kolla-ansible command:

(kayobe) $ kayobe kolla ansible run <command>

Dumping Kayobe Configuration

The Ansible configuration space is quite large, and it can be hard to determine the final values of Ansible variables. We can use Kayobe’s configuration dump command to view individual variables or the variables for one or more hosts. To dump Kayobe configuration for one or more hosts:

(kayobe) $ kayobe configuration dump

The output is a JSON-formatted object mapping hosts to their hostvars.

We can use the --var-name argument to inspect a particular variable or the --host or --hosts arguments to view a variable or variables for a specific host or set of hosts.

Checking Network Connectivity

In complex networking environments it can be useful to be able to automatically check network connectivity and diagnose networking issues. To perform some simple connectivity checks:

(kayobe) $ kayobe network connectivity check

Note that this will run on the seed, seed hypervisor, and overcloud hosts. If any of these hosts are not expected to be active (e.g. prior to overcloud deployment), the set of target hosts may be limited using the --limit argument.
