nova_console_poller

nova_console_poller - ansible role

Role to deploy nova-console-poller service on the OpenShift cluster for monitoring serial console output of Nova instances.

The poller monitors the serial console of Nova instances and can be used for debugging boot issues, kernel panics, and other console-based troubleshooting.

This role consists of templated Kubernetes manifests that deploy one container per Nova instance UUID.

The automation-vars.yml is used with the hotloop role to apply the resources on the OpenShift cluster.

Requirements

• OpenStack clouds.yaml and cacert.pem in cloud_config_dir
• At least one instance UUID in instances_uuids (role does nothing if empty)
• The role automatically creates the sushy-emulator namespace and OpenStack credentials secret if they don't exist

Features

• One container per Nova instance
• Automatic console monitoring
• Deployed in sushy-emulator namespace
