6.16. Customizing Puppet Configuration Data

The Heat template collection contains a set of parameters to pass extra configuration to certain node types. These parameters save the configuration as hieradata for the node's Puppet configuration. These parameters are:

To add extra configuration to the post-deployment configuration process, create an environment file that contains these parameters in the parameter_defaults section. For example, to increase the reserved memory for Compute hosts to 1024 MB and set the VNC keymap to Japanese:

parameter_defaults:
  NovaComputeExtraConfig:
    nova::compute::reserved_host_memory: 1024
    nova::compute::vnc_keymap: ja

Include this environment file when running openstack overcloud deploy.
