Variables

var EsxPort int

EsxPort used to connect to ESX, passed in as command line param

Types

type EsxVmdkCmd

type EsxVmdkCmd struct {
	Mtx *sync.Mutex // For serialization of Run comand/response
}

EsxVmdkCmd struct - empty , we use it only to implement VmdkCmdRunner interface

func (EsxVmdkCmd) Run

func (vmdkCmd EsxVmdkCmd) Run(cmd string, name string, opts map[string]string) ([]byte, error)

Run command Guest VM requests on ESX via vmdkops_serv.py listening on vSocket * * For each request: * - Establishes a vSocket connection * - Sends json string up to ESX * - waits for reply and returns resulting JSON or an error

type MockVmdkCmd

type MockVmdkCmd struct{}

MockVmdkCmd struct

func NewMockCmd

func NewMockCmd() MockVmdkCmd

NewMockCmd returns a new instance of MockVmdkCmd.

func (MockVmdkCmd) Run

func (mockCmd MockVmdkCmd) Run(cmd string, name string, opts map[string]string) ([]byte, error)

Run returns JSON responses to each command or an error

type VmdkCmdRunner

type VmdkCmdRunner interface {
	Run(cmd string, name string, opts map[string]string) ([]byte, error)
}

VmdkCmdRunner interface for sending Vmdk Commands to an ESX server.

type VmdkOps

type VmdkOps struct {
	Cmd VmdkCmdRunner // see *_vmdkcmd.go for implementations.
}

VmdkOps struct

func (VmdkOps) Attach

func (v VmdkOps) Attach(name string, opts map[string]string) (*fs.VolumeDevSpec, error)

Attach attaches a volume and returns the disk's VolumeDevSpec.

func (VmdkOps) Create

func (v VmdkOps) Create(name string, opts map[string]string) error

Create a volume

func (VmdkOps) Detach

func (v VmdkOps) Detach(name string, opts map[string]string) error

Detach a volume

func (VmdkOps) Get

func (v VmdkOps) Get(name string) (map[string]interface{}, error)

Get for volume

func (VmdkOps) List

func (v VmdkOps) List() ([]VolumeData, error)

List all volumes

func (VmdkOps) RawAttach

func (v VmdkOps) RawAttach(name string, opts map[string]string) ([]byte, error)

RawAttach attaches a volume and returns `[]byte` representing the raw response string.

func (VmdkOps) Remove

func (v VmdkOps) Remove(name string, opts map[string]string) error

Remove a volume

type VolumeData

type VolumeData struct {
	Name       string
	Attributes map[string]string
}

VolumeData we return to the caller

type VolumeInfo

type VolumeInfo struct {
	Name    string            `json:"Name"`
	Options map[string]string `json:"Opts,omitempty"`
}

VolumeInfo we get about the volume from upstairs
