Note

For more information about RHOSP, please refer to its documentation pages.

Deployment Steps

Prepare the environment files

RHOSP makes use of TripleO Heat Templates (THT), which allows you to define the Overcloud resources by creating environment files.

To ensure that your RHOSP environment is correctly configured to use Glance Image Cache on Pure Storage FlashArrays edit your version of cinder-pure-config.yaml and add the following information:

parameter_defaults:
  ControllerExtraConfig:
    cinder::config::cinder_config:
      DEFAULT/cinder_internal_tenant_project_id:
        value: PROJECT_ID
    cinder::config::cinder_config:
      DEFAULT/cinder_internal_tenant_user_id:
        value: USER_ID

This will render the required parameters in the cinder.conf file as:

[DEFAULT]
cinder_internal_tenant_project_id=PROJECT_ID
cinder_internal_tenant_user_id=USER_ID
