Usage with sudo?

[mcmdev]

I've just found the tool and I'm very impressed, but I can't figure out how to use sudo on a remote server.
From what I've read in the documentation is supposed to run not interactively, so I could provide a password with sudo -S.
Considering that I'm running a script only on one server at a time I'd rather have an interactive session, which seems to be possible using the --tty parameter, but then I don't SSH into the server automatically anymore.

What's the recommended solution here?

sake does not yet support interactive shells, it's something on the roadmap but no timeline available atm since I'm swamped with other stuff. The tty parameter just means that the sake command is replaced with the cmd in the task which allows interactive use.

So for instance, given this task:

  test:
    tty: false
    cmd: echo "Press enter to continue"; read var1

Basically without tty:

1. sake run <cmd>
2. sake uses the ssh client to send text to a server which is executed on the server (note, the ssh client process is a child process of sake)
3. User presses enter, nothing happens since it's not an interactive shell

With tty set to true:

1. sake run <cmd>
2. sake replaces the current shell with the command (so it's not longer a child process but the main)
3. User presses enter, you return to the shell

The code responsible for tty:

func ExecTTY(cmd string, envs []string) error {
	shell := "bash"
	foundShell, found := os.LookupEnv("SHELL")
	if found {
		shell = foundShell
	}

	execBin, err := exec.LookPath(shell)
	if err != nil {
		return err
	}

	userEnv := append(os.Environ(), envs...)
	err = unix.Exec(execBin, []string{shell, "-c", cmd}, userEnv)
	if err != nil {
		return err
	}

	return nil
}

There's 2 solutions I can think of to solve your problem:

1. Use sudoless password for the user? https://serverfault.com/questions/160581/how-to-setup-passwordless-sudo-on-linux, that's how I get around interactive prompts for sudo.

2. Write a custom ssh command using the -t flag, see https://unix.stackexchange.com/questions/243821/run-a-command-in-an-interactive-shell-with-ssh-after-sourcing-bashrc, so something like:

  test:
    tty: true
    cmd: ssh -t $S_USER@$S_HOST "read var1; echo 123"
