Functions

func RegisterCloudProvider

func RegisterCloudProvider(name string, cloud Factory)

RegisterCloudProvider registers a cloudprovider.Factory by name. This is expected to happen during app startup.

Types

type Clusters added in v0.2.1

type Clusters interface {
	// List lists the names of the available clusters.
	ListClusters() ([]string, error)
	// Master gets back the address (either DNS name or IP address) of the master node for the cluster.
	Master(clusterName string) (string, error)
}

Clusters is an abstract, pluggable interface for clusters of containers.

type Factory

type Factory func(config io.Reader) (Interface, error)

Factory is a function that returns a cloudprovider.Interface. The config parameter provides an io.Reader handler to the factory in order to load specific configurations. If no configuration is provided the parameter is nil.

type Instances

type Instances interface {
	// IPAddress returns an IP address of the specified instance.
	IPAddress(name string) (net.IP, error)
	// List lists instances that match 'filter' which is a regular expression which must match the entire instance name (fqdn)
	List(filter string) ([]string, error)
	// GetNodeResources gets the resources for a particular node
	GetNodeResources(name string) (*api.NodeResources, error)
}

Instances is an abstract, pluggable interface for sets of instances.

type Interface

type Interface interface {
	// TCPLoadBalancer returns a balancer interface. Also returns true if the interface is supported, false otherwise.
	TCPLoadBalancer() (TCPLoadBalancer, bool)
	// Instances returns an instances interface. Also returns true if the interface is supported, false otherwise.
	Instances() (Instances, bool)
	// Zones returns a zones interface. Also returns true if the interface is supported, false otherwise.
	Zones() (Zones, bool)
	// Clusters returns a clusters interface.  Also returns true if the interface is supported, false otherwise.
	Clusters() (Clusters, bool)
}

Interface is an abstract, pluggable interface for cloud providers.

func GetCloudProvider

func GetCloudProvider(name string, config io.Reader) (Interface, error)

GetCloudProvider creates an instance of the named cloud provider, or nil if the name is not known. The error return is only used if the named provider was known but failed to initialize. The config parameter specifies the io.Reader handler of the configuration file for the cloud provider, or nil for no configuation.

func InitCloudProvider added in v0.2.1

func InitCloudProvider(name string, configFilePath string) Interface

InitCloudProvider creates an instance of the named cloud provider.

type TCPLoadBalancer

type TCPLoadBalancer interface {
	// TCPLoadBalancerExists returns whether the specified load balancer exists.
	// TODO: Break this up into different interfaces (LB, etc) when we have more than one type of service
	TCPLoadBalancerExists(name, region string) (bool, error)
	// CreateTCPLoadBalancer creates a new tcp load balancer. Returns the IP address of the balancer
	CreateTCPLoadBalancer(name, region string, externalIP net.IP, port int, hosts []string, affinityType api.AffinityType) (net.IP, error)
	// UpdateTCPLoadBalancer updates hosts under the specified load balancer.
	UpdateTCPLoadBalancer(name, region string, hosts []string) error
	// DeleteTCPLoadBalancer deletes a specified load balancer.
	DeleteTCPLoadBalancer(name, region string) error
}

TCPLoadBalancer is an abstract, pluggable interface for TCP load balancers.

type Zone

type Zone struct {
	FailureDomain string
	Region        string
}

Zone represents the location of a particular machine.

type Zones

type Zones interface {
	// GetZone returns the Zone containing the current failure zone and locality region that the program is running in
	GetZone() (Zone, error)
}

Zones is an abstract, pluggable interface for zone enumeration.
