Functions

Types

type Client 

type Client interface {
	Get(string) (*http.Response, error)
}

Client is an interface that expects a Get method similar to http.Get. This is needed for unit testing, since we can mock an http client. Thus, the client will usually be an http.Client EXCEPT in unit tests.

type CreateOpts 

type CreateOpts struct {
	// The name of the stack. It must start with an alphabetic character.
	Name string `json:"stack_name" required:"true"`
	// A structure that contains either the template file or url. Call the
	// associated methods to extract the information relevant to send in a create request.
	TemplateOpts *Template `json:"-" required:"true"`
	// Enables or disables deletion of all stack resources when a stack
	// creation fails. Default is true, meaning all resources are not deleted when
	// stack creation fails.
	DisableRollback *bool `json:"disable_rollback,omitempty"`
	// A structure that contains details for the environment of the stack.
	EnvironmentOpts *Environment `json:"-"`
	// User-defined parameters to pass to the template.
	Parameters map[string]interface{} `json:"parameters,omitempty"`
	// The timeout for stack creation in minutes.
	Timeout int `json:"timeout_mins,omitempty"`
	// A list of tags to assosciate with the Stack
	Tags []string `json:"-"`
}

CreateOpts is the common options struct used in this package's Create operation.

type CreateOptsBuilder 

type CreateOptsBuilder interface {
	ToStackCreateMap() (map[string]interface{}, error)
}

CreateOptsBuilder is the interface options structs have to satisfy in order to be used in the main Create operation in this package. Since many extensions decorate or modify the common logic, it is useful for them to satisfy a basic interface in order for them to be used.

Stack struct

func ExtractStacks 

func ExtractStacks(r pagination.Page) ([]StackList, error)
