Functions

func CheckPrivateSshConnection

func CheckPrivateSshConnection(t *testing.T, publicHost Host, privateHost Host, command string) string

CheckPrivateSshConnection attempts to connect to privateHost (which is not addressable from the Internet) via a separate publicHost (which is addressable from the Internet) and then executes "command" on privateHost and returns its output. It is useful for checking that it's possible to SSH from a Bastion Host to a private instance.

func CheckPrivateSshConnectionE

func CheckPrivateSshConnectionE(t *testing.T, publicHost Host, privateHost Host, command string) (string, error)

CheckPrivateSshConnection attempts to connect to privateHost (which is not addressable from the Internet) via a separate publicHost (which is addressable from the Internet) and then executes "command" on privateHost and returns its output. It is useful for checking that it's possible to SSH from a Bastion Host to a private instance.

func CheckSshCommand

func CheckSshCommand(t *testing.T, host Host, command string) string

Check that you can connect via SSH to the given host and run the given command. Returns the stdout/stderr.

func CheckSshCommandE

func CheckSshCommandE(t *testing.T, host Host, command string) (string, error)

Check that you can connect via SSH to the given host and run the given command. Returns the stdout/stderr.

func CheckSshConnection

func CheckSshConnection(t *testing.T, host Host)

Check that you can connect via SSH to the given host and fail the test if the connection fails.

func CheckSshConnectionE

func CheckSshConnectionE(t *testing.T, host Host) error

Check that you can connect via SSH to the given host and return an error if the connection fails

func Close

func Close(t *testing.T, closeable Closeable, ignoreErrors ...string)

func NoOpHostKeyCallback

func NoOpHostKeyCallback(hostname string, remote net.Addr, key ssh.PublicKey) error

An ssh.HostKeyCallback that does nothing. Only use this when you're sure you don't want to check the host key at all (e.g., only for testing and non-production use cases).

Types

type Closeable

type Closeable interface {
	Close() error
}

type Host

type Host struct {
	Hostname    string
	SshUserName string
	SshKeyPair  *KeyPair
}

type JumpHostSession

type JumpHostSession struct {
	JumpHostClient        *ssh.Client
	HostVirtualConnection net.Conn
	HostConnection        ssh.Conn
}

func (*JumpHostSession) Cleanup

func (jumpHost *JumpHostSession) Cleanup(t *testing.T)

type KeyPair

type KeyPair struct {
	PublicKey  string
	PrivateKey string
}

A public and private key pair that can be used for SSH access

func GenerateRSAKeyPair

func GenerateRSAKeyPair(t *testing.T, keySize int) *KeyPair

Generate an RSA Keypair and return the public and private keys

func GenerateRSAKeyPairE

func GenerateRSAKeyPairE(t *testing.T, keySize int) (*KeyPair, error)

Generate an RSA Keypair and return the public and private keys

type SshConnectionOptions

type SshConnectionOptions struct {
	Username    string
	Address     string
	Port        int
	AuthMethods []ssh.AuthMethod
	Command     string
	JumpHost    *SshConnectionOptions
}

func (*SshConnectionOptions) ConnectionString

func (options *SshConnectionOptions) ConnectionString() string

type SshSession

type SshSession struct {
	Options  *SshConnectionOptions
	Client   *ssh.Client
	Session  *ssh.Session
	JumpHost *JumpHostSession
}

A container object for all resources created by an SSH session. The reason we need this is so that we can do a single defer in a top-level method that calls the Cleanup method to go through and ensure all of these resources are released and cleaned up.

func (*SshSession) Cleanup

func (sshSession *SshSession) Cleanup(t *testing.T)
