Functions

func NewAlicloudPlugin

func NewAlicloudPlugin(pluginSPI spi.PluginSPI) driver.Driver

NewAlicloudPlugin returns a new Alicloud machine plugin.

Types

type MachinePlugin

type MachinePlugin struct {
	SPI spi.PluginSPI
}

MachinePlugin implements the driver.Driver It also implements the PluginSPI interface

func (*MachinePlugin) CreateMachine

func (plugin *MachinePlugin) CreateMachine(ctx context.Context, req *driver.CreateMachineRequest) (*driver.CreateMachineResponse, error)

CreateMachine handles a machine creation request REQUIRED METHOD

REQUEST PARAMETERS (driver.CreateMachineRequest) Machine *v1alpha1.Machine Machine object from whom VM is to be created MachineClass *v1alpha1.MachineClass MachineClass backing the machine object Secret *corev1.Secret Kubernetes secret that contains any sensitive data/credentials

RESPONSE PARAMETERS (driver.CreateMachineResponse) ProviderID string Unique identification of the VM at the cloud provider. This could be the same/different from req.MachineName.

ProviderID typically matches with the node.Spec.ProviderID on the node object.
Eg: gce://project-name/region/vm-ProviderID

NodeName string Returns the name of the node-object that the VM register's with Kubernetes.

This could be different from req.MachineName as well

LastKnownState string (Optional) Last known state of VM during the current operation.

Could be helpful to continue operations in future requests.

OPTIONAL IMPLEMENTATION LOGIC It is optionally expected by the safety controller to use an identification mechanisms to map the VM Created by a providerSpec. These could be done using tag(s)/resource-groups etc. This logic is used by safety controller to delete orphan VMs which are not backed by any machine CRD

func (*MachinePlugin) DeleteMachine

func (plugin *MachinePlugin) DeleteMachine(ctx context.Context, req *driver.DeleteMachineRequest) (*driver.DeleteMachineResponse, error)

DeleteMachine handles a machine deletion request

REQUEST PARAMETERS (driver.DeleteMachineRequest) Machine *v1alpha1.Machine Machine object from whom VM is to be deleted MachineClass *v1alpha1.MachineClass MachineClass backing the machine object Secret *corev1.Secret Kubernetes secret that contains any sensitive data/credentials

RESPONSE PARAMETERS (driver.DeleteMachineResponse) LastKnownState bytes(blob) (Optional) Last known state of VM during the current operation.

Could be helpful to continue operations in future requests.

func (*MachinePlugin) GetMachineStatus

func (plugin *MachinePlugin) GetMachineStatus(ctx context.Context, req *driver.GetMachineStatusRequest) (*driver.GetMachineStatusResponse, error)

GetMachineStatus handles a machine get status request OPTIONAL METHOD

REQUEST PARAMETERS (driver.GetMachineStatusRequest) Machine *v1alpha1.Machine Machine object from whom VM status needs to be returned MachineClass *v1alpha1.MachineClass MachineClass backing the machine object Secret *corev1.Secret Kubernetes secret that contains any sensitive data/credentials

RESPONSE PARAMETERS (driver.GetMachineStatueResponse) ProviderID string Unique identification of the VM at the cloud provider. This could be the same/different from req.MachineName.

ProviderID typically matches with the node.Spec.ProviderID on the node object.
Eg: gce://project-name/region/vm-ProviderID

NodeName string Returns the name of the node-object that the VM register's with Kubernetes.

This could be different from req.MachineName as well

The request should return a NOT_FOUND (5) status error code if the machine is not existing

func (*MachinePlugin) GetVolumeIDs

func (plugin *MachinePlugin) GetVolumeIDs(ctx context.Context, req *driver.GetVolumeIDsRequest) (*driver.GetVolumeIDsResponse, error)

GetVolumeIDs returns a list of Volume IDs for all PV Specs for whom an provider volume was found

REQUEST PARAMETERS (driver.GetVolumeIDsRequest) PVSpecList []*corev1.PersistentVolumeSpec PVSpecsList is a list PV specs for whom volume-IDs are required.

RESPONSE PARAMETERS (driver.GetVolumeIDsResponse) VolumeIDs []string VolumeIDs is a repeated list of VolumeIDs.

func (*MachinePlugin) InitializeMachine

func (plugin *MachinePlugin) InitializeMachine(_ context.Context, _ *driver.InitializeMachineRequest) (*driver.InitializeMachineResponse, error)

InitializeMachine handles VM initialization for Alibaba Cloud VM's. Currently, un-implemented.

func (*MachinePlugin) ListMachines

func (plugin *MachinePlugin) ListMachines(ctx context.Context, req *driver.ListMachinesRequest) (*driver.ListMachinesResponse, error)

ListMachines lists all the machines possibilly created by a providerSpec Identifying machines created by a given providerSpec depends on the OPTIONAL IMPLEMENTATION LOGIC you have used to identify machines created by a providerSpec. It could be tags/resource-groups etc OPTIONAL METHOD

REQUEST PARAMETERS (driver.ListMachinesRequest) MachineClass *v1alpha1.MachineClass MachineClass based on which VMs created have to be listed Secret *corev1.Secret Kubernetes secret that contains any sensitive data/credentials

RESPONSE PARAMETERS (driver.ListMachinesResponse) MachineList map<string,string> A map containing the keys as the MachineID and value as the MachineName

for all machine's who where possibilly created by this ProviderSpec
