5. Run the deployment command and include the core heat templates, environment files, and this new custom environment file.

   Important

   The order of the environment files is important as the parameters and resources defined in subsequent environment files take precedence.

   Example

   $ openstack overcloud deploy --templates \
   -e <your_environment_files> \
   -e /usr/share/openstack-tripleo-heat-templates/environments/services/octavia.yaml \
   -e /home/stack/templates/my-octavia-environment.yaml
