Tomamos los cambios del bash

bext@bext-VPCF13WFX:~$ source /etc/bash_completion.d/docker-machine-prompt.bash

Queda actualizar el prompt el cual indicará la docker-machine, se editara en el .bashrc modificando la variable PS1 agregando $(__docker_machine_ps1) como acomode a nuestro gusto

ejemplo PS1='[\u@\h \W$(__docker_machine_ps1)]\$ '

Este es el .bashrc original
...

if [ "$color_prompt" = yes ]; then
    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\$
else
    PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
fi
unset color_prompt force_color_prompt

# If this is an xterm set the title to user@host:dir
case "$TERM" in
xterm*|rxvt*)
    PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h: \w\a\]$PS1"
    ;;
*)
    ;;
esac
