# Note:
#   This deployment file is designed for 'quickstart' of multus, easy installation to test it,
#   hence this deployment yaml does not care about following things intentionally.
#     - various configuration options
#     - minor deployment scenario
#     - upgrade/update/uninstall scenario
#   Multus team understand users deployment scenarios are diverse, hence we do not cover
#   comprehensive deployment scenario. We expect that it is covered by each platform deployment.
