service (Managing Services)
Syntax
Release Information
Standard Linux command used for managing and viewing services in Contrail Controller Release 1.0.
Description
Start, stop, or restart a Contrail service. Display the status of a Contrail service.
All contrail services are managed by the process supervisord, which is open source software written in Python. Each Contrail node type, such as compute, control, and so on, has an instance of supervisord that, when running, launches Contrail services as child processes. All supervisord instances display in contrail-status output with the prefix supervisor. If the supervisord instance of a particular node type is not up, none of the services for that node type are up. For more details about the open source supervisord process, see http://www.supervisord.org.
Options
- start—start a named service.
- stop—stop a named service.
- restart—stop and restart a named service.
- status—display the status of a named service.
