fuse environment shell

Attach an interactive terminal to a running environment's guest

fuse environment shell <id>          # alias: ssh
fuse environment shell <id> -- top

With no command this opens the guest’s login shell. A command after -- runs instead of the shell, still on a terminal.

This is a relayed pty, not SSH: there is no scp, no port forwarding, and no key-based login. It needs a real terminal and refuses to run when stdin and stdout are not a tty, so for scripted commands use exec. The session exits with the guest command’s exit code.

shell requires the master token. It is root in the guest, and API keys carry no scopes today, so anything weaker would silently make every issued key a root shell on every VM in the fleet.
