Overcloud ansible templates

overcloud_services jinja template

The overcloud_services jinja template is taking a dictionary from the default variable overcloud_services. The dictionary is composed by: nodes and services. Those value would build the heat environment file required for deploying the overcloud with the specify services.

Example: if you want to deploy only keystone, just override the overcloud_services variable in a yaml file with:

overcloud_services:

  • name: 'ControllerServices:' services:
    • OS::TripleO::Services::Kernel
    • OS::TripleO::Services::Keystone
    • OS::TripleO::Services::RabbitMQ
    • OS::TripleO::Services::MySQL
    • OS::TripleO::Services::HAproxy
    • OS::TripleO::Services::Keepalived
    • OS::TripleO::Services::Ntp
    • OS::TripleO::Services::Timezone
    • OS::TripleO::Services::TripleoPackages

Or with keystone and nova:

overcloud_services:

  • name: 'ControllerServices:' services:
    • OS::TripleO::Services::Kernel
    • OS::TripleO::Services::Keystone
    • OS::TripleO::Services::RabbitMQ
    • OS::TripleO::Services::MySQL
    • OS::TripleO::Services::HAproxy
    • OS::TripleO::Services::Keepalived
    • OS::TripleO::Services::Ntp
    • OS::TripleO::Services::Timezone
    • OS::TripleO::Services::TripleoPackages
  • name: 'ComputeServices:' services:
    • OS::TripleO::Services::NovaCompute
