func (az *Cloud) Clusters() (cloudprovider.Clusters, bool)

func (*Cloud) CreateRoute 

func (az *Cloud) CreateRoute(clusterName string, nameHint string, kubeRoute *cloudprovider.Route) error

CreateRoute creates the described managed route route.Name will be ignored, although the cloud-provider may use nameHint to create a more user-meaningful name.

func (az *Cloud) CreateVolume(name, storageAccount, storageType, location string, requestGB int) (string, string, int, error)

CreateVolume creates a VHD blob in a storage account that has storageType and location using the given storage account. If no storage account is given, search all the storage accounts associated with the resource group and pick one that fits storage type and location.

func (*Cloud) CurrentNodeName 

func (az *Cloud) CurrentNodeName(hostname string) (types.NodeName, error)

CurrentNodeName returns the name of the node we are currently running on On most clouds (e.g. GCE) this is the hostname, so we provide the hostname

func (az *Cloud) DeleteFileShare(accountName, key, name string) error

DeleteFileShare deletes a file share using storage account name and key

func (*Cloud) DeleteRoute 

func (az *Cloud) DeleteRoute(clusterName string, kubeRoute *cloudprovider.Route) error

func (*Cloud) DeleteVolume 

func (az *Cloud) DeleteVolume(name, uri string) error

DeleteVolume deletes a VHD blob

func (*Cloud) DetachDiskByName 

func (az *Cloud) DetachDiskByName(diskName, diskURI string, nodeName types.NodeName) error

DetachDiskByName detaches a vhd from host the vhd can be identified by diskName or diskURI

DisksAreAttached checks if a list of volumes are attached to the node with the specified NodeName

func (*Cloud) EnsureLoadBalancer 

func (az *Cloud) EnsureLoadBalancer(clusterName string, service *v1.Service, nodes []*v1.Node) (*v1.LoadBalancerStatus, error)

EnsureLoadBalancer creates a new load balancer 'name', or updates the existing one. Returns the status of the balancer

func (*Cloud) EnsureLoadBalancerDeleted 

func (az *Cloud) EnsureLoadBalancerDeleted(clusterName string, service *v1.Service) error

EnsureLoadBalancerDeleted deletes the specified load balancer if it exists, returning nil if the load balancer specified either didn't exist or was successfully deleted. This construction is useful because many cloud providers' load balancers have multiple underlying components, meaning a Get could say that the LB doesn't exist even if some part of it is still laying around.

func (*Cloud) ExternalID 

func (az *Cloud) ExternalID(name types.NodeName) (string, error)

ExternalID returns the cloud provider ID of the specified instance (deprecated).

func (*Cloud) GetDiskLun 

func (az *Cloud) GetDiskLun(diskName, diskURI string, nodeName types.NodeName) (int32, error)

GetDiskLun finds the lun on the host that the vhd is attached to, given a vhd's diskName and diskURI

func (*Cloud) GetLoadBalancer 

func (az *Cloud) GetLoadBalancer(clusterName string, service *v1.Service) (status *v1.LoadBalancerStatus, exists bool, err error)

GetLoadBalancer returns whether the specified load balancer exists, and if so, what its status is.

func (*Cloud) GetNextDiskLun 

func (az *Cloud) GetNextDiskLun(nodeName types.NodeName) (int32, error)

GetNextDiskLun searches all vhd attachment on the host and find unused lun return -1 if all luns are used

func (*Cloud) GetZone 

func (az *Cloud) GetZone() (cloudprovider.Zone, error)

GetZone returns the Zone containing the current failure zone and locality region that the program is running in

func (*Cloud) InstanceID 

func (az *Cloud) InstanceID(name types.NodeName) (string, error)

InstanceID returns the cloud provider ID of the specified instance. Note that if the instance does not exist or is no longer running, we must return ("", cloudprovider.InstanceNotFound)

func (*Cloud) InstanceType 

func (az *Cloud) InstanceType(name types.NodeName) (string, error)

InstanceType returns the type of the specified instance. Note that if the instance does not exist or is no longer running, we must return ("", cloudprovider.InstanceNotFound) (Implementer Note): This is used by kubelet. Kubelet will label the node. Real log from kubelet: 

Adding node label from cloud provider: beta.kubernetes.io/instance-type=[value]

func (*Cloud) Instances 

func (az *Cloud) Instances() (cloudprovider.Instances, bool)

Instances returns an instances interface. Also returns true if the interface is supported, false otherwise.

UpdateLoadBalancer updates hosts under the specified load balancer.

func (*Cloud) Zones 

func (az *Cloud) Zones() (cloudprovider.Zones, bool)

type Config 

type Config struct {
	// The cloud environment identifier. Takes values from https://github.com/Azure/go-autorest/blob/ec5f4903f77ed9927ac95b19ab8e44ada64c1356/autorest/azure/environments.go#L13
	Cloud string `json:"cloud" yaml:"cloud"`

	TenantID string `json:"tenantId" yaml:"tenantId"`
	// The ID of the Azure Subscription that the cluster is deployed in
	SubscriptionID string `json:"subscriptionId" yaml:"subscriptionId"`
	// The name of the resource group that the cluster is deployed in
	ResourceGroup string `json:"resourceGroup" yaml:"resourceGroup"`
	// The location of the resource group that the cluster is deployed in
	Location string `json:"location" yaml:"location"`
	// The name of the VNet that the cluster is deployed in
	VnetName string `json:"vnetName" yaml:"vnetName"`
	// The name of the subnet that the cluster is deployed in
	SubnetName string `json:"subnetName" yaml:"subnetName"`

	SecurityGroupName string `json:"securityGroupName" yaml:"securityGroupName"`
	// (Optional in 1.6) The name of the route table attached to the subnet that the cluster is deployed in
	RouteTableName string `json:"routeTableName" yaml:"routeTableName"`
	// (Optional) The name of the availability set that should be used as the load balancer backend
	// If this is set, the Azure cloudprovider will only add nodes from that availability set to the load
	// balancer backend pool. If this is not set, and multiple agent pools (availability sets) are used, then
	// the cloudprovider will try to add all nodes to a single backend pool which is forbidden.
	// In other words, if you use multiple agent pools (availability sets), you MUST set this field.
	PrimaryAvailabilitySetName string `json:"primaryAvailabilitySetName" yaml:"primaryAvailabilitySetName"`

	// The ClientID for an AAD application with RBAC access to talk to Azure RM APIs
	AADClientID string `json:"aadClientId" yaml:"aadClientId"`
	// The ClientSecret for an AAD application with RBAC access to talk to Azure RM APIs
	AADClientSecret string `json:"aadClientSecret" yaml:"aadClientSecret"`
