  During
  xref:../install_config/install/advanced_install.adoc#install-config-install-advanced-install[advanced installations],
  the `BuildOverrides` plug-in can
  be configured using the following parameters, which are configurable in the inventory file:
  
  - `openshift_buildoverrides_force_pull`
  - `openshift_buildoverrides_image_labels`
  - `openshift_buildoverrides_nodeselectors`
  - `openshift_buildoverrides_annotations`
