func SSHFileSigner

func SSHFileSigner(path string) (ssh.Signer, error)

SSHFileSigner returns an ssh.Signer for a key file.

func TestPEM

func TestPEM(t *testing.T) string

Types

type Config

type Config struct {
	Type string `mapstructure:"communicator"`

	// SSH
	SSHHost              string        `mapstructure:"ssh_host"`
	SSHPort              int           `mapstructure:"ssh_port"`
	SSHUsername          string        `mapstructure:"ssh_username"`
	SSHPassword          string        `mapstructure:"ssh_password"`
	SSHPrivateKey        string        `mapstructure:"ssh_private_key_file"`
	SSHPty               bool          `mapstructure:"ssh_pty"`
	SSHTimeout           time.Duration `mapstructure:"ssh_timeout"`
	SSHHandshakeAttempts int           `mapstructure:"ssh_handshake_attempts"`

	// WinRM
	WinRMUser     string        `mapstructure:"winrm_username"`
	WinRMPassword string        `mapstructure:"winrm_password"`
	WinRMHost     string        `mapstructure:"winrm_host"`
	WinRMPort     int           `mapstructure:"winrm_port"`
	WinRMTimeout  time.Duration `mapstructure:"winrm_timeout"`
}

Config is the common configuration that communicators allow within a builder.

func (*Config) Port

func (c *Config) Port() int

Port returns the port that will be used for access based on config.

func (*Config) Prepare

func (c *Config) Prepare(ctx *interpolate.Context) []error

type StepConnect

type StepConnect struct {
	// Config is the communicator config struct
	Config *Config

	// Host should return a host that can be connected to for communicator
	// connections.
	Host func(multistep.StateBag) (string, error)

	// The fields below are callbacks to assist with connecting to SSH.
	//
	// SSHConfig should return the default configuration for
	// connecting via SSH.
	SSHConfig func(multistep.StateBag) (*gossh.ClientConfig, error)
	SSHPort   func(multistep.StateBag) (int, error)

	// The fields below are callbacks to assist with connecting to WinRM.
	//
	// WinRMConfig should return the default configuration for
	// connecting via WinRM.
	WinRMConfig func(multistep.StateBag) (*WinRMConfig, error)

	// CustomConnect can be set to have custom connectors for specific
	// types. These take highest precedence so you can also override
	// existing types.
	CustomConnect map[string]multistep.Step
	// contains filtered or unexported fields
}

StepConnect is a multistep Step implementation that connects to the proper communicator and stores it in the "communicator" key in the state bag.

func (*StepConnect) Cleanup

func (s *StepConnect) Cleanup(state multistep.StateBag)

func (*StepConnect) Run

func (s *StepConnect) Run(state multistep.StateBag) multistep.StepAction

type StepConnectSSH

type StepConnectSSH struct {
	// All the fields below are documented on StepConnect
	Config    *Config
	Host      func(multistep.StateBag) (string, error)
	SSHConfig func(multistep.StateBag) (*gossh.ClientConfig, error)
	SSHPort   func(multistep.StateBag) (int, error)
}

StepConnectSSH is a step that only connects to SSH.

In general, you should use StepConnect.

func (*StepConnectSSH) Cleanup

func (s *StepConnectSSH) Cleanup(multistep.StateBag)

func (*StepConnectSSH) Run

func (s *StepConnectSSH) Run(state multistep.StateBag) multistep.StepAction

type StepConnectWinRM

type StepConnectWinRM struct {
	// All the fields below are documented on StepConnect
	Config      *Config
	Host        func(multistep.StateBag) (string, error)
	WinRMConfig func(multistep.StateBag) (*WinRMConfig, error)
}

StepConnectWinRM is a multistep Step implementation that waits for WinRM to become available. It gets the connection information from a single configuration when creating the step.

Uses:

ui packer.Ui

Produces:

communicator packer.Communicator

func (*StepConnectWinRM) Cleanup

func (s *StepConnectWinRM) Cleanup(multistep.StateBag)

func (*StepConnectWinRM) Run

func (s *StepConnectWinRM) Run(state multistep.StateBag) multistep.StepAction

type WinRMConfig

type WinRMConfig struct {
	Username string
	Password string
}

WinRMConfig is configuration that can be returned at runtime to dynamically configure WinRM.
