Functions

func DefaultGalaxyTemplate 

func DefaultGalaxyTemplate() []byte

Return a default template to create our base stack.

func Exists(name string) (bool, error)

func GalaxyTemplate 

func GalaxyTemplate(params *GalaxyTmplParams) ([]byte, error)

func ListActive() ([]string, error)

return a list of all actives stacks

func ListFailures 

func ListFailures(id string, since time.Time) ([]string, error)

List failures on a stack as "STATUS:REASON"

func SetPolicy 

func SetPolicy(name string, policy []byte) error

set a stack policy TODO: add delete policy

func Wait 

func Wait(name string, timeout time.Duration) error

Wait for a stack event to complete. Poll every 5s while the stack is in the CREATE_IN_PROGRESS or UPDATE_IN_PROGRESS state, and succeed when it enters a successful _COMPLETE state. Return and error of ErrTimeout if the timeout is reached.

func WaitForComplete 

func WaitForComplete(id string, timeout time.Duration) error

Like the Wait function, but instead if returning as soon as there is an error, always wait for a final status. ** This assumes all _COMPLETE statuses are final, and all final statuses end 

in _COMPLETE.

type Pool 

type Pool struct {

}

A Pool can be marshaled directly into a Cloudformation template for our pools. This is Purposely constrained to our usage, with some values specifically using intrinsic functions, and other assumed prerequisites. This should only matter if the poolTmpl is modified, or we attempt to update an arbitrarily added pool template.

}

Resources from the base stack that may need to be referenced from other stacks

func GetSharedResources 

func GetSharedResources(stackName string) (SharedResources, error)

Return the SharedResources from our base stack that are needed for pool stacks. We need the IDs for subnets and security groups, since they cannot be referenced by name in a VPC. We also lookup the IAM instance profile created by the base stack for use in pool's launch configs. This could be cached to disk so that we don't need to lookup the base stack to build a pool template.

func (SharedResources) ListSubnets 

func (s SharedResources) ListSubnets() []string

Return a list of the subnet values.

type Subnet 

type Subnet struct {
	ID                        string `xml:"subnetId"`
	State                     string `xml:"state"`
	VPCID                     string `xml:"vpcId"`
	CIDRBlock                 string `xml:"cidrBlock"`
