func (f *FakeCloud) TCPLoadBalancer() (TCPLoadBalancer, bool)

TCPLoadBalancer returns a fake implementation of TCPLoadBalancer.

Actually it just returns f itself.

func (*FakeCloud) TCPLoadBalancerExists

func (f *FakeCloud) TCPLoadBalancerExists(name, region string) (bool, error)

TCPLoadBalancerExists is a stub implementation of TCPLoadBalancer.TCPLoadBalancerExists.

func (*FakeCloud) UpdateTCPLoadBalancer

func (f *FakeCloud) UpdateTCPLoadBalancer(name, region string, hosts []string) error

UpdateTCPLoadBalancer is a test-spy implementation of TCPLoadBalancer.UpdateTCPLoadBalancer. It adds an entry "update" into the internal method call record.

func (*FakeCloud) Zones

func (f *FakeCloud) Zones() (Zones, bool)

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)
}

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)
}

Interface is an abstract, pluggable interface for cloud providers

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.
	CreateTCPLoadBalancer(name, region string, port int, hosts []string) error
