type AzureManager

type AzureManager struct {
	// contains filtered or unexported fields
}

AzureManager handles Azure communication and data caching.

func CreateAzureManager

func CreateAzureManager(configReader io.Reader) (*AzureManager, error)

CreateAzureManager creates Azure Manager object to work with Azure.

func (*AzureManager) DeleteInstances

func (m *AzureManager) DeleteInstances(instances []*AzureRef) error

DeleteInstances deletes the given instances. All instances must be controlled by the same ASG.

func (*AzureManager) GetScaleSetForInstance

func (m *AzureManager) GetScaleSetForInstance(instance *AzureRef) (*ScaleSet, error)

GetScaleSetForInstance returns ScaleSetConfig of the given Instance

func (*AzureManager) GetScaleSetSize

func (m *AzureManager) GetScaleSetSize(asConfig *ScaleSet) (int64, error)

GetScaleSetSize gets Scale Set size.

func (*AzureManager) GetScaleSetVms

func (m *AzureManager) GetScaleSetVms(scaleSet *ScaleSet) ([]string, error)

GetScaleSetVms returns list of nodes for the given scale set.

func (*AzureManager) RegisterScaleSet

func (m *AzureManager) RegisterScaleSet(scaleSet *ScaleSet)

RegisterScaleSet registers scale set in Azure Manager.

func (*AzureManager) SetScaleSetSize

func (m *AzureManager) SetScaleSetSize(asConfig *ScaleSet, size int64) error

SetScaleSetSize sets ScaleSet size.

type AzureRef

type AzureRef struct {
	Name string
}

AzureRef contains a reference to some entity in Azure world.

func AzureRefFromProviderId

func AzureRefFromProviderId(id string) (*AzureRef, error)

AzureRefFromProviderId creates InstanceConfig object from provider id which must be in format: azure:///resourceGroupName/name

func (*AzureRef) GetKey

func (m *AzureRef) GetKey() string

GetKey returns key of the given azure reference.

type Config

type Config struct {
	Cloud                      string `json:"cloud" yaml:"cloud"`
	TenantID                   string `json:"tenantId" yaml:"tenantId"`
	SubscriptionID             string `json:"subscriptionId" yaml:"subscriptionId"`
	ResourceGroup              string `json:"resourceGroup" yaml:"resourceGroup"`
	Location                   string `json:"location" yaml:"location"`
	VnetName                   string `json:"vnetName" yaml:"vnetName"`

}

Config holds the configuration parsed from the --cloud-config flag

type ScaleSet

type ScaleSet struct {
	AzureRef
	// contains filtered or unexported fields
}

ScaleSet implements NodeGroup interface.

func (*ScaleSet) Belongs

func (scaleSet *ScaleSet) Belongs(node *apiv1.Node) (bool, error)

Belongs returns true if the given node belongs to the NodeGroup.

func (*ScaleSet) Debug

func (scaleSet *ScaleSet) Debug() string

Debug returns a debug string for the Scale Set.

func (*ScaleSet) DecreaseTargetSize

func (scaleSet *ScaleSet) DecreaseTargetSize(delta int) error

DecreaseTargetSize decreases the target size of the node group. This function doesn't permit to delete any existing node and can be used only to reduce the request for new nodes that have not been yet fulfilled. Delta should be negative. It is assumed that cloud provider will not delete the existing nodes if the size when there is an option to just decrease the target.

func (*ScaleSet) DeleteNodes

func (scaleSet *ScaleSet) DeleteNodes(nodes []*apiv1.Node) error

DeleteNodes deletes the nodes from the group.

func (*ScaleSet) Id

func (scaleSet *ScaleSet) Id() string

Id returns ScaleSet id.
