Functions

func IDFromName

func IDFromName(client *gophercloud.ServiceClient, name string) (string, error)

IDFromName is a convienience function that returns a snapshot's ID given its name.

func List

func List(client *gophercloud.ServiceClient, opts ListOptsBuilder) pagination.Pager

List returns Snapshots optionally limited by the conditions provided in ListOpts.

func WaitForStatus

func WaitForStatus(c *gophercloud.ServiceClient, id, status string, secs int) error

WaitForStatus will continually poll the resource, checking for a particular status. It will do this for the amount of seconds defined.

Types

type CreateOpts

type CreateOpts struct {
	VolumeID    string                 `json:"volume_id" required:"true"`
	Description string                 `json:"display_description,omitempty"`
	Force       bool                   `json:"force,omitempty"`

	Name        string                 `json:"display_name,omitempty"`
}

CreateOpts contains options for creating a Snapshot. This object is passed to the snapshots.Create function. For more information about these parameters, see the Snapshot object.

func (CreateOpts) ToSnapshotCreateMap

func (opts CreateOpts) ToSnapshotCreateMap() (map[string]interface{}, error)

ToSnapshotCreateMap assembles a request body based on the contents of a CreateOpts.

type CreateOptsBuilder

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

CreateOptsBuilder allows extensions to add additional parameters to the Create request.

type CreateResult

type CreateResult struct {
	// contains filtered or unexported fields
}

CreateResult contains the response body and error from a Create request.

func Create

func Create(client *gophercloud.ServiceClient, opts CreateOptsBuilder) (r CreateResult)

Create will create a new Snapshot based on the values in CreateOpts. To extract the Snapshot object from the response, call the Extract method on the CreateResult.

func (CreateResult) Extract

func (r CreateResult) Extract() (*Snapshot, error)

Extract will get the Snapshot object out of the commonResult object.

type DeleteResult

type DeleteResult struct {
	gophercloud.ErrResult
}

DeleteResult contains the response body and error from a Delete request.

func Delete

func Delete(client *gophercloud.ServiceClient, id string) (r DeleteResult)

Delete will delete the existing Snapshot with the provided ID.

type GetResult

type GetResult struct {
	// contains filtered or unexported fields
}

GetResult contains the response body and error from a Get request.

func Get

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

Get retrieves the Snapshot with the provided ID. To extract the Snapshot object from the response, call the Extract method on the GetResult.

func (GetResult) Extract

func (r GetResult) Extract() (*Snapshot, error)

Extract will get the Snapshot object out of the commonResult object.

type ListOpts

type ListOpts struct {
	Name     string `q:"display_name"`
	Status   string `q:"status"`
	VolumeID string `q:"volume_id"`
}

ListOpts hold options for listing Snapshots. It is passed to the snapshots.List function.

func (ListOpts) ToSnapshotListQuery

func (opts ListOpts) ToSnapshotListQuery() (string, error)

ToSnapshotListQuery formats a ListOpts into a query string.

type ListOptsBuilder

type ListOptsBuilder interface {
	ToSnapshotListQuery() (string, error)
}

ListOptsBuilder allows extensions to add additional parameters to the List request.

type Snapshot

type Snapshot struct {
	// Currect status of the Snapshot.
	Status string `json:"status"`

	// Display name.
	Name string `json:"display_name"`

	// Instances onto which the Snapshot is attached.
	Attachments []string `json:"attachments"`

	// Logical group.
	AvailabilityZone string `json:"availability_zone"`

	// Is the Snapshot bootable?
	Bootable string `json:"bootable"`

	// Date created.
	CreatedAt time.Time `json:"-"`

	// Display description.
	Description string `json:"display_description"`

	// See VolumeType object for more information.
	VolumeType string `json:"volume_type"`

	// ID of the Snapshot from which this Snapshot was created.
	SnapshotID string `json:"snapshot_id"`

	// ID of the Volume from which this Snapshot was created.
	VolumeID string `json:"volume_id"`

	// User-defined key-value pairs.
	Metadata map[string]string `json:"metadata"`

	// Unique identifier.
	ID string `json:"id"`

	// Size of the Snapshot, in GB.
	Size int `json:"size"`
}

Snapshot contains all the information associated with an OpenStack Snapshot.

func ExtractSnapshots

func ExtractSnapshots(r pagination.Page) ([]Snapshot, error)
