Method Details [hide private]

UpgradeConfig(self)

source code 

Fill defaults for missing configuration values.

Overrides: ConfigObject.UpgradeConfig

primary_hypervisor(self)

source code 

The first hypervisor is the primary.

Useful, for example, for Node's hv/disk state.

Decorators:
  • @property

ToDict(self, _with_private=False)

source code 

Custom function for cluster.

Parameters:
  • _with_private - if True, the object will leak its private fields in the dictionary representation. If False, the values will be replaced with None.
Overrides: ConfigObject.ToDict

FromDict(cls, val)
Class Method

source code 

Custom function for cluster.

Overrides: ConfigObject.FromDict

SimpleFillDP(self, diskparams)

source code 

Fill a given diskparams dict with cluster defaults.

Parameters:
  • diskparams - The diskparams
Returns:
The defaults dict

GetHVDefaults(self, hypervisor, os_name=None, skip_keys=None)

source code 

Get the default hypervisor parameters for the cluster.

Parameters:
  • hypervisor - the hypervisor name
  • os_name - if specified, we'll also update the defaults for this OS
  • skip_keys - if passed, list of keys not to use
Returns:
the defaults dict

SimpleFillHV(self, hv_name, os_name, hvparams, skip_globals=False)

source code 

Fill a given hvparams dict with cluster defaults.

Parameters:
  • hv_name (string) - the hypervisor to use
  • os_name (string) - the OS to use for overriding the hypervisor defaults
  • skip_globals (boolean) - if True, the global hypervisor parameters will not be filled
Returns: dict
a copy of the given hvparams with missing keys filled from the cluster defaults

FillHV(self, instance, skip_globals=False)

source code 

Fill an instance's hvparams dict with cluster defaults.

Parameters:
  • instance (objects.Instance) - the instance parameter to fill
  • skip_globals (boolean) - if True, the global hypervisor parameters will not be filled
Returns: dict
a copy of the instance's hvparams with missing keys filled from the cluster defaults

SimpleFillBE(self, beparams)

source code 

Fill a given beparams dict with cluster defaults.

Parameters:
  • beparams (dict) - the dict to fill
Returns: dict
a copy of the passed in beparams with missing keys filled from the cluster defaults

FillBE(self, instance)

source code 

Fill an instance's beparams dict with cluster defaults.

Parameters:
Returns: dict
a copy of the instance's beparams with missing keys filled from the cluster defaults

SimpleFillNIC(self, nicparams)

source code 

Fill a given nicparams dict with cluster defaults.

Parameters:
  • nicparams (dict) - the dict to fill
Returns: dict
a copy of the passed in nicparams with missing keys filled from the cluster defaults

SimpleFillOS(self, os_name, os_params_public, os_params_private=None, os_params_secret=None)

source code 

Fill an instance's osparams dict with cluster defaults.

Parameters:
  • os_name (string) - the OS name to use
  • os_params_public (dict) - the dict to fill with default values
  • os_params_private (dict) - the dict with private fields to fill with default values. Not passing this field results in no private fields being added to the return value. Private fields will be wrapped in Private objects.
  • os_params_secret (dict) - the dict with secret fields to fill with default values. Not passing this field results in no secret fields being added to the return value. Private fields will be wrapped in Private objects.
Returns: dict
a copy of the instance's osparams with missing keys filled from the cluster defaults. Private and secret parameters are not included unless the respective optional parameters are supplied.

FillND(self, node, nodegroup)

source code 

Return filled out ndparams for objects.NodeGroup and objects.Node

Parameters:
  • node (objects.Node) - A Node object to fill
  • nodegroup (objects.NodeGroup) - A Node object to fill @return a copy of the node's ndparams with defaults filled

FillNDGroup(self, nodegroup)

source code 

Return filled out ndparams for just objects.NodeGroup

Parameters:
  • nodegroup (objects.NodeGroup) - A Node object to fill @return a copy of the node group's ndparams with defaults filled

SimpleFillND(self, ndparams)

source code 

Fill a given ndparams dict with defaults.

Parameters:
  • ndparams (dict) - the dict to fill
Returns: dict
a copy of the passed in ndparams with missing keys filled from the cluster defaults

SimpleFillIPolicy(self, ipolicy)
