Functions ¶
func ResolveDependencies ¶
ResolveDependencies returns a list of dependencies by parsing the opaque Properties blob.
Types ¶
type FlavorPlugin ¶
type FlavorPlugin struct {
Plugin plugin.Name
Properties *types.Any // this will be the Spec of the plugin
}
FlavorPlugin describes the flavor configuration
type InstancePlugin ¶
type InstancePlugin struct {
Plugin plugin.Name
Properties *types.Any // this will be the Spec of the plugin
}
InstancePlugin is the structure that describes an instance plugin.
type Options ¶
type Options struct {
// Self is set when the controller is part of a group that can be updated.
Self *instance.LogicalID
// PollInterval is the frequency for syncing the state
PollInterval types.Duration
// MaxParallelNum is the max number of parallel instance operation. Default =0 (no limit)
MaxParallelNum uint
// PollIntervalGroupSpec polls for group spec at this interval to update the metadata paths
PollIntervalGroupSpec types.Duration
// PollIntervalGroupDetail polls for group details at this interval to update the metadata paths
PollIntervalGroupDetail types.Duration
}
Options capture the options for starting up the group controller.
type SkipBeforeInstanceDestroy ¶
type SkipBeforeInstanceDestroy string
SkipBeforeInstanceDestroy defines the action that should be skipped prior destroying the instance.
func (SkipBeforeInstanceDestroy) MarshalJSON ¶
func (s SkipBeforeInstanceDestroy) MarshalJSON() ([]byte, error)
MarshalJSON returns the json representation
func (*SkipBeforeInstanceDestroy) UnmarshalJSON ¶
func (s *SkipBeforeInstanceDestroy) UnmarshalJSON(buff []byte) error
UnmarshalJSON unmarshals the buffer to this struct
type Spec ¶
type Spec struct {
Instance InstancePlugin
Flavor FlavorPlugin
Allocation group.AllocationMethod
Updating Updating
}
Spec is the configuration schema for the plugin, provided in group.Spec.Properties
func ParseProperties ¶
ParseProperties parses the group plugin properties JSON document in a group configuration.
func (Spec) InstanceHash ¶
InstanceHash computes a stable hash of the document in InstancePluginProperties.
type Updating ¶
type Updating struct {
Duration types.Duration
Count int
SkipBeforeInstanceDestroy *SkipBeforeInstanceDestroy
}
Updating is the configuration schema using on a rolling update and defines how long a node must be healthy before the next node is updated. If Duration is set then the node must be healthy for at least the specified time. If Count is set then the node must be healthy for specified number of poll intervals. Both Duration and Count cannot be non 0.
