PROGRAM:
NAME
cloud-sandbox - launch a cloud instance and ssh directly into it, as a 'sandbox' system
SYNOPSIS
cloud-sandbox [instance-type [ubuntu-release]] [ec2-run-instance-options]
DESCRIPTION
cloud-sandbox is a program that launches a cloud instance (EC2 by default), automatically
generates ssh host keys, ssh's into the launched system, and prompts the user for instance
termination on exit.
cloud-sandbox does the following:
- conveniently supports simple parameters for instance-type and ubuntu-release, by
passing those to ubuntu-ec2-run(1)
- generates ssh-host keys locally using ssh-keygen(1), and passes them to the instance
- automatically adds host key fingerprints to a local host keys file,
$HOME/.ssh/known_hosts.cloud, which removes the interactive fingerprint prompt
- uses ssh-import-id(1) in the instance to import the user's public SSH key, if the
environment variable $LAUNCHPAD_ID exists
- uses bootmail(1) to send the user email noting that the instance has booted, if the
environment variable $BOOTMAIL exists and is a valid email address
- waits in a loop for sshd(8) to start on the cloud instance
- execs an ssh(1) session to the instance
- upon exit, interactively prompts the user if they want to immediately terminate the
instance and remote the ssh known host key
