|---|---|
| [cells] | |
scheduler =
nova.cells.scheduler.CellsScheduler |
(String) Cells scheduler The class of the driver used by the cells scheduler. This should be the full Python path to the class to be used. If nothing is specified in this option, the CellsScheduler is used. Possible values: * 'nova.cells.scheduler.CellsScheduler' is the default option * Otherwise it should be the full Python path to the class to be used Services which consume this: * nova-cells Related options: * None |
| [upgrade_levels] | |
cells = None |
(String) Cells version Cells client-side RPC API version. Use this option to set a version cap for messages sent to local cells services. Possible values: * None: This is the default value. * grizzly: message version 1.6. * havana: message version 1.24. * icehouse: message version 1.27. * juno: message version 1.29. * kilo: message version 1.34. * liberty: message version 1.37. Services which consume this: * nova-cells Related options: * None |
cert = None |
(String) Specifies the maximum version for messages sent from cert
services. This should be the minimum value that is supported by all of
the deployed cert services. Possible values: Any valid OpenStack release
name, in lower case, such as 'mitaka' or 'liberty'. Alternatively, it
can be any string representing a version number in the format 'N.N'; for
example, possible values might be '1.12' or '2.0'. * Services which
consume this: nova-cert * Related options: None |
compute = None |
(String) Set a version cap for messages sent to compute services. Set this option to "auto" if you want to let the compute RPC module automatically determine what version to use based on the service versions in the deployment. Otherwise, you can set this to a specific version to pin this service to messages at a particular level. All services of a single type (i.e. compute) should be configured to use the same version, and it should be set to the minimum commonly-supported version of all those services in the deployment. |
conductor = None |
(String) Set a version cap for messages sent to conductor services |
console = None |
(String) Set a version cap for messages sent to console services |
consoleauth = None |
(String) Set a version cap for messages sent to consoleauth services |
intercell = None |
(String) Intercell version Intercell RPC API is the client side of the Cell<->Cell RPC API. Use this option to set a version cap for messages sent between cells services. Possible values: * None: This is the default value. * grizzly: message version 1.0. Services which consume this: * nova-cells Related options: * None |
network = None |
(String) Set a version cap for messages sent to network services |
scheduler = None |
(String) Sets a version cap (limit) for messages sent to scheduler
services. In the situation where there were multiple scheduler services
running, and they were not being upgraded together, you would set this
to the lowest deployed version to guarantee that other services never
send messages that any of your running schedulers cannot understand.
This is rarely needed in practice as most deployments run a single
scheduler. It exists mainly for design compatibility with the other
services, such as compute, which are routinely upgraded in a rolling
fashion. * Services that use this:
nova-compute, nova-conductor * Related options: None |
