The OpenContrail v4.x configuration files are generated by SaltStack
and then mounted into containers as volumes. SaltStack also provides
a mechanism to apply configuration changes by restarting the systemd
services inside a container.
To modify the OpenContrail v4.x configurations:
Log in to the Salt Master node.
Make necessary configuration changes in the
classes/cluster/<cluster_name>/opencontrail folder.
Apply the opencontrail state specific to the OpenContrail configuration
file where the changes were made. For example, if you made changes in the
database.yaml file:
salt -C 'I@opencontrail:database' state.apply opencontrail
After the state is applied, the systemd services are automatically
restarted inside the OpenContrail container in question
to apply the configuration changes.
