Overview

Package images provides information and interaction with the image API resource in the OpenStack Compute service.

An image is a collection of files used to create or rebuild a server. Operators provide a number of pre-built OS images by default. You may also create custom images from cloud servers you have launched.

	gophercloud.Result
}

GetResult temporarily stores a Get response.

func Get

func Get(client *gophercloud.ServiceClient, id string) GetResult

Get acquires additional detail about a specific image by ID. Use ExtractImage() to interpret the result as an openstack Image.

func (GetResult) Extract

func (gr GetResult) Extract() (*Image, error)

Extract interprets a GetResult as an Image.

type Image

type Image struct {
	// ID contains the image's unique identifier.
	ID string

	Created string

	// MinDisk and MinRAM specify the minimum resources a server must provide to be able to install the image.
	MinDisk int
	MinRAM  int

	// Name provides a human-readable moniker for the OS image.
	Name string

	// The Progress and Status fields indicate image-creation status.
	// Any usable image will have 100% progress.
	Progress int
	Status   string

func ExtractImages

func ExtractImages(page pagination.Page) ([]Image, error)

ExtractImages converts a page of List results into a slice of usable Image structs.

type ImagePage

type ImagePage struct {
	pagination.LinkedPageBase
}

ImagePage contains a single page of results from a List operation. Use ExtractImages to convert it into a slice of usable structs.

func (ImagePage) IsEmpty

func (page ImagePage) IsEmpty() (bool, error)

IsEmpty returns true if a page contains no Image results.

func (ImagePage) NextPageURL

func (page ImagePage) NextPageURL() (string, error)

NextPageURL uses the response's embedded link reference to navigate to the next page of results.

type ListOpts

type ListOpts struct {
	// When the image last changed status (in date-time format).
	ChangesSince string `q:"changes-since"`
	// The number of Images to return.
	Limit int `q:"limit"`
	// UUID of the Image at which to set a marker.
	Marker string `q:"marker"`
	// The name of the Image.
	Name string `q:"name:"`
	// The name of the Server (in URL format).
	Server string `q:"server"`
