Types ¶
type EasySSHExecutor ¶ added in v1.0.9
type EasySSHExecutor struct { Config *easyssh.MakeConfig Locale string // the locale used when executing the command Sudo bool // all commands run with this executor will be using sudo }
EasySSHExecutor implements Executor with EasySSH as transportation layer.
func (*EasySSHExecutor) Execute ¶ added in v1.0.9
func (e *EasySSHExecutor) Execute(cmd string, sudo bool, timeout ...time.Duration) ([]byte, []byte, error)
Execute run the command via SSH, it's not invoking any specific shell by default.
func (*EasySSHExecutor) Transfer ¶ added in v1.0.9
func (e *EasySSHExecutor) Transfer(src string, dst string, download bool) error
Transfer copies files via SCP This function depends on `scp` (a tool from OpenSSH or other SSH implementation) This function is based on easyssh.MakeConfig.Scp() but with support of copying file from remote to local.
type Executor ¶ added in v1.0.7
type Executor interface { // Execute run the command, then return it's stdout and stderr // NOTE: stdin is not supported as it seems we don't need it (for now). If // at some point in the future we need to pass stdin to a command, we'll // need to refactor this function and its implementations. // If the cmd can't quit in timeout, it will return error, the default timeout is 60 seconds. Execute(cmd string, sudo bool, timeout ...time.Duration) (stdout []byte, stderr []byte, err error) // Transfer copies files from or to a target Transfer(src string, dst string, download bool) error }
Executor is the executor interface for TiOps, all tasks will in the end be passed to a executor and then be actually performed.
type NativeSSHExecutor ¶ added in v1.0.9
type NativeSSHExecutor struct { Config *SSHConfig Locale string // the locale used when executing the command Sudo bool // all commands run with this executor will be using sudo ConnectionTestResult error // test if the connection can be established in initialization phase }
NativeSSHExecutor implements Excutor with native SSH transportation layer.
type SSHConfig ¶
type SSHConfig struct { Host string // hostname of the SSH server Port int // port of the SSH server User string // username to login to the SSH server Password string // password of the user KeyFile string // path to the private key file Passphrase string // passphrase of the private key file // Timeout is the maximum amount of time for the TCP connection to establish. Timeout time.Duration }
SSHConfig is the configuration needed to establish SSH connection.
