Types

type MachinePlugin 

type MachinePlugin struct {
	SPI PluginSPI
}

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

func NewGCPPlugin 

func NewGCPPlugin(pluginSPI PluginSPI) *MachinePlugin

NewGCPPlugin returns a new Gcp plugin

func (*MachinePlugin) CreateMachine 

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

CreateMachine handles a machine creation request REQUIRED METHOD

REQUEST PARAMETERS (driver.CreateMachineRequest) MachineName string Contains the name of the machine object for whom an VM is to be created at the provider ProviderSpec bytes(blob) Template/Configuration of the machine to be created is given by at the provider Secrets map<string,bytes> (Optional) Contains a map from string to string contains any cloud specific secrets that can be used by the provider LastKnownState bytes(blob) (Optional) Last known state of VM during last operation. Could be helpful to continue operation from previous state

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 bytes(blob) (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) CreateMachineUtil 

func (ms *MachinePlugin) CreateMachineUtil(ctx context.Context, machineName string, providerSpec *api.GCPProviderSpec, secret *corev1.Secret) (string, error)

CreateMachineUtil method is used to create a GCP machine

func (*MachinePlugin) DeleteMachine 

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

DeleteMachine handles a machine deletion request

REQUEST PARAMETERS (driver.DeleteMachineRequest) MachineName string Contains the name of the machine object for the backing VM(s) have to be deleted ProviderID string Contains the unique identification of the VM at the cloud provider ProviderSpec bytes(blob) Template/Configuration of the machine to be deleted is given by at the provider Secrets map<string,bytes> (Optional) Contains a map from string to string contains any cloud specific secrets that can be used by the provider LastKnownState bytes(blob) (Optional) Last known state of VM during last operation. Could be helpful to continue operation from previous state

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) DeleteMachineUtil 

func (ms *MachinePlugin) DeleteMachineUtil(ctx context.Context, machineName string, _ string, providerSpec *api.GCPProviderSpec, secret *corev1.Secret) (string, error)

DeleteMachineUtil deletes a VM by name

func (*MachinePlugin) GetMachineStatus 

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

GetMachineStatus handles a machine get status request OPTIONAL METHOD

REQUEST PARAMETERS (driver.GetMachineStatusRequest) MachineName string Contains the name of the machine object for whose status is to be retrived ProviderID string Contains the unique identification of the VM at the cloud provider ProviderSpec bytes(blob) Template/Configuration of the machine whose status is to be retrived Secrets map<string,bytes> (Optional) Contains a map from string to string contains any cloud specific secrets that can be used by the provider

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

func (*MachinePlugin) GetMachineStatusUtil 

func (ms *MachinePlugin) GetMachineStatusUtil(ctx context.Context, machineName string, _ string, providerSpec *api.GCPProviderSpec, secret *corev1.Secret) (string, error)

GetMachineStatusUtil checks for existence of VM by name

func (*MachinePlugin) GetVolumeIDs 

func (ms *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 bytes(blob) PVSpecsList is a list PV specs for whom volume-IDs are required. Plugin should parse this raw data into pre-defined list of PVSpecs.

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

func (*MachinePlugin) ListMachines 

func (ms *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) ProviderSpec bytes(blob) Template/Configuration of the machine that wouldn've been created by this ProviderSpec (Machine Class) Secrets map<string,bytes> (Optional) Contains a map from string to string contains any cloud specific secrets that can be used by the provider

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

func (*MachinePlugin) ListMachinesUtil 

func (ms *MachinePlugin) ListMachinesUtil(ctx context.Context, providerSpec *api.GCPProviderSpec, secret *corev1.Secret) (map[string]string, error)

ListMachinesUtil lists all VMs in the DC or folder

type PluginSPI 

type PluginSPI interface {
	NewComputeService(secrets *corev1.Secret) (context.Context, *compute.Service, error)
}

PluginSPI provides an interface to deal with cloud provider session You can optionally enhance this interface to add interface methods here You can use it to mock cloud provider calls

type PluginSPIImpl 

type PluginSPIImpl struct{}

PluginSPIImpl is the real implementation of PluginSPI interface that makes the calls to the provider SDK

func (*PluginSPIImpl) NewComputeService 

func (spi *PluginSPIImpl) NewComputeService(secret *corev1.Secret) (context.Context, *compute.Service, error)

NewComputeService returns an instance of the compute service
