# 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.
